Tortuguero, Costa Rica
–
Tortuguero, Costa Rica, which can be translated as Land of Turtles, is a village on the Northern Caribbean coast of Costa Rica in the Limón Province. It gave its name to the neighboring Tortuguero National Park, the village is situated on a sand bar island, separated from the mainland by Tortuguero River and bordering the Caribbean Sea. Tortuguero is renowned for its navigable canals that run through the rainforest in the national park, the beaches around Tortuguero are key nesting sites for four species of sea turtle, including two critically endangered species. The National Park is also host to a biodiversity of insects, resident and migratory birds. Accordingly, there are four biological stations — the John H, the small village, which can be reached only by boat or airplane, is sustained almost entirely by eco-tourism. The ocean here can be dangerous to swim in due to rough surf, Tortuguero is only accessible by boat or plane. There is an airstrip which serves daily flights from Nature Air via San José. Charter flights are available with Nature Air or Sansa Airlines. Boat transportation is available via La Pavona to the North or Moín to the South, during September and October many local guides will offer tourists the opportunity to help turtle nests hatch. The canals of Tortuguero gave the town its nickname of Costa Ricas Amazon, many guided boat tours leave Tortuguero and the surrounding lodges to see the wildlife, jungle, and canals. Cerro Tortuguero has been closed by the National Park and National Reserve service due to overuse. Many local guides will still offer tours, for hikers, Cerro Tortuguero is a small hill roughly 6 km north of the village, accessible only by boat. Its only 119 m high, but offers views of the area.

Costa Rica
–
It has a population of around 4.5 million, of whom nearly a quarter live in the metropolitan area of the capital and largest city, San José. Costa Rica was sparsely inhabited by people before coming under Spanish rule in the 16th century. Since then, Costa Rica has remained among the most stable, prosperous, following a brief civil war, it permanently abolished its army in 1949, becoming one of only a few sovereign nations without a standing army. Costa Rica is a member of the Organisation Internationale de la Francophonie. The country has consistently performed favourably in the Human Development Index, placing 69th in the world as of 2015 and its rapidly developing economy, once heavily dependent on agriculture, has diversified to include sectors such as finance, pharmaceuticals, and ecotourism. Costa Rica is known for its environmental policies, being the only country to meet all five UNDP criteria established to measure environmental sustainability. Costa Rica officially plans to become a country by 2021. In 2012, it became the first country in the Americas to ban recreational hunting, historians have classified the indigenous people of Costa Rica as belonging to the Intermediate Area, where the peripheries of the Mesoamerican and Andean native cultures overlapped. More recently, pre-Columbian Costa Rica has also described as part of the Isthmo-Colombian Area. The oldest evidence of occupation in Costa Rica is associated with the arrival of various groups of hunter-gatherers about 10,000 to 7,000 years BCE in the Turrialba Valley. The presence of Clovis culture type spearheads and arrows from South America opens the possibility that, in this area, agriculture became evident in the populations that lived in Costa Rica about 5,000 years ago. They mainly grew tubers and roots, for the first and second millennia BCE there were already settled farming communities. These were small and scattered, although the transition from hunting and gathering to agriculture as the livelihood in the territory is still unknown. The earliest use of pottery appears around 2,000 to 3,000 BCE, shards of pots, cylindrical vases, platters, gourds and other forms of vases decorated with grooves, prints, and some modelled after animals have been found. The impact of indigenous peoples on modern Costa Rican culture has been small compared to other nations. Costa Rica was described as the poorest and most miserable Spanish colony in all America by a Spanish governor in 1719, for all these reasons, Costa Rica was, by and large, unappreciated and overlooked by the Spanish Crown and left to develop on its own. Costa Rica became a democracy with no oppressed mestizo or indigenous class. It was not long before Spanish settlers turned to the hills, where they found rich volcanic soil, like the rest of Central America, Costa Rica never fought for independence from Spain

Taxonomy (biology)
–
Taxonomy is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. The exact definition of taxonomy varies from source to source, but the core of the remains, the conception, naming. There is some disagreement as to whether biological nomenclature is considered a part of taxonomy, the broadest meaning of taxonomy is used here. The word taxonomy was introduced in 1813 by Candolle, in his Théorie élémentaire de la botanique, the term alpha taxonomy is primarily used today to refer to the discipline of finding, describing, and naming taxa, particularly species. In earlier literature, the term had a different meaning, referring to morphological taxonomy, ideals can, it may be said, never be completely realized. They have, however, a value of acting as permanent stimulants. Some of us please ourselves by thinking we are now groping in a beta taxonomy, turrill thus explicitly excludes from alpha taxonomy various areas of study that he includes within taxonomy as a whole, such as ecology, physiology, genetics, and cytology. He further excludes phylogenetic reconstruction from alpha taxonomy, thus, Ernst Mayr in 1968 defined beta taxonomy as the classification of ranks higher than species. This activity is what the term denotes, it is also referred to as beta taxonomy. How species should be defined in a group of organisms gives rise to practical and theoretical problems that are referred to as the species problem. The scientific work of deciding how to define species has been called microtaxonomy, by extension, macrotaxonomy is the study of groups at higher taxonomic ranks, from subgenus and above only, than species. While some descriptions of taxonomic history attempt to date taxonomy to ancient civilizations, earlier works were primarily descriptive, and focused on plants that were useful in agriculture or medicine. There are a number of stages in scientific thinking. Early taxonomy was based on criteria, the so-called artificial systems. Later came systems based on a complete consideration of the characteristics of taxa, referred to as natural systems, such as those of de Jussieu, de Candolle and Bentham. The publication of Charles Darwins Origin of Species led to new ways of thinking about classification based on evolutionary relationships and this was the concept of phyletic systems, from 1883 onwards. This approach was typified by those of Eichler and Engler, the advent of molecular genetics and statistical methodology allowed the creation of the modern era of phylogenetic systems based on cladistics, rather than morphology alone. Taxonomy has been called the worlds oldest profession, and naming and classifying our surroundings has likely been taking place as long as mankind has been able to communicate

Plant
–
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The term is generally limited to the green plants, which form an unranked clade Viridiplantae. This includes the plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae. Green plants have cell walls containing cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts and their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce amounts of chlorophyll or to photosynthesize. Plants are characterized by sexual reproduction and alternation of generations, although reproduction is also common. There are about 300–315 thousand species of plants, of which the great majority, green plants provide most of the worlds molecular oxygen and are the basis of most of Earths ecologies, especially on land. Plants that produce grains, fruits and vegetables form humankinds basic foodstuffs, Plants play many roles in culture. They are used as ornaments and, until recently and in variety, they have served as the source of most medicines. The scientific study of plants is known as botany, a branch of biology, Plants are one of the two groups into which all living things were traditionally divided, the other is animals. The division goes back at least as far as Aristotle, who distinguished between plants, which generally do not move, and animals, which often are mobile to catch their food. Much later, when Linnaeus created the basis of the system of scientific classification. Since then, it has become clear that the plant kingdom as originally defined included several unrelated groups, however, these organisms are still often considered plants, particularly in popular contexts. When the name Plantae or plant is applied to a group of organisms or taxon. The evolutionary history of plants is not yet settled. Those which have been called plants are in bold, the way in which the groups of green algae are combined and named varies considerably between authors. Algae comprise several different groups of organisms which produce energy through photosynthesis, most conspicuous among the algae are the seaweeds, multicellular algae that may roughly resemble land plants, but are classified among the brown, red and green algae. Each of these groups also includes various microscopic and single-celled organisms

Flowering plant
–
The flowering plants, also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approx. 13,164 known genera and a total of c.295,383 known species, etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term angiosperm comes from the Greek composite word meaning enclosed seeds, the ancestors of flowering plants diverged from gymnosperms in the Triassic Period, during the range 245 to 202 million years ago, and the first flowering plants are known from 160 mya. They diversified extensively during the Lower Cretaceous, became widespread by 120 mya, angiosperms differ from other seed plants in several ways, described in the table. These distinguishing characteristics taken together have made the angiosperms the most diverse and numerous land plants, the amount and complexity of tissue-formation in flowering plants exceeds that of gymnosperms. The vascular bundles of the stem are arranged such that the xylem and phloem form concentric rings, in the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium, the soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Among the monocotyledons, the bundles are more numerous in the stem and are scattered through the ground tissue. They contain no cambium and once formed the stem increases in diameter only in exceptional cases, the characteristic feature of angiosperms is the flower. Flowers show remarkable variation in form and elaboration, and provide the most trustworthy external characteristics for establishing relationships among angiosperm species, the function of the flower is to ensure fertilization of the ovule and development of fruit containing seeds. The floral apparatus may arise terminally on a shoot or from the axil of a leaf, occasionally, as in violets, a flower arises singly in the axil of an ordinary foliage-leaf. There are two kinds of cells produced by flowers. Microspores, which divide to become pollen grains, are the male cells and are borne in the stamens. The female cells called megaspores, which divide to become the egg cell, are contained in the ovule. The flower may consist only of parts, as in willow. Usually, other structures are present and serve to protect the sporophylls, the individual members of these surrounding structures are known as sepals and petals. The outer series is usually green and leaf-like, and functions to protect the rest of the flower, the inner series is, in general, white or brightly colored, and is more delicate in structure. It functions to attract insect or bird pollinators, attraction is effected by color, scent, and nectar, which may be secreted in some part of the flower

Eudicots
–
The eudicots, Eudicotidae or eudicotyledons are a monophyletic clade of flowering plants that had been called tricolpates or non-magnoliid dicots by previous authors. The close relationships among flowering plants with tricolpate pollen grains was initially seen in studies of shared derived characters. These plants have a trait in their pollen grains of exhibiting three colpi or grooves paralleling the polar axis. Later molecular evidence confirmed the basis for the evolutionary relationships among flowering plants with tricolpate pollen grains. The term means true dicotyledons, as it contains the majority of plants that have been considered dicots and have characteristics of the dicots, the term eudicots has subsequently been widely adopted in botany to refer to one of the two largest clades of angiosperms, monocots being the other. The remaining angiosperms are sometimes referred to as basal angiosperms or paleodicots, the other name for the eudicots is tricolpates, a name which refers to the grooved structure of the pollen. Members of the group have tricolpate pollen, or forms derived from it and these pollens have three or more pores set in furrows called colpi. In contrast, most of the seed plants produce monosulcate pollen. The name tricolpates is preferred by some botanists to avoid confusion with the dicots, numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Most leafy trees of midlatitudes also belong to eudicots, with exceptions being magnolias and tulip trees which belong to magnoliids, and Ginkgo biloba. The name eudicots is used in the APG system, of 1998 and it is applied to a clade, a monophyletic group, which includes most of the dicots. The eudicots can be divided into two groups, the basal eudicots and the core eudicots, basal eudicot is an informal name for a paraphyletic group. The core eudicots are a monophyletic group, a 2010 study suggested the core eudicots can be divided into two clades, Gunnerales and a clade called Pentapetalae, comprising all the remaining core eudicots

Rosids
–
The rosids are members of a large clade of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification and these orders, in turn, together comprise about 140 families. Fossil rosids are known from the Cretaceous period, molecular clock estimates indicate that the rosids originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. The name is based upon the name Rosidae, which had usually been understood to be a subclass, in 1967, Armen Takhtajan showed that the correct basis for the name Rosidae is a description of a group of plants published in 1830 by Friedrich Gottlieb Bartling. The clade was later renamed Rosidae and has been variously delimited by different authors, the name rosids is informal and not assumed to have any particular taxonomic rank like the names authorized by the ICBN. The rosids are monophyletic based upon evidence found by molecular phylogenetic analysis, three different definitions of the rosids were used. Some authors included the orders Saxifragales and Vitales in the rosids, others excluded both of these orders. The circumscription used in this article is that of the APG IV classification, which includes Vitales, the rosids and Saxifragales form the superrosids clade. This is one of three groups compose the Pentapetalae, the others being Dilleniales and the superasterids. The rosids consist of two groups, the order Vitales and the eurosids, the eurosids, in turn, are divided into two groups, fabids and malvids. The rosids consist of 17 orders, in addition to Vitales, there are 8 orders in fabids and 8 orders in malvids. Some of the orders have only recently been recognized and these are Vitales, Zygophyllales, Crossosomatales, Picramniales, and Huerteales. The phylogeny of Rosids shown below is adapted from the Angiosperm Phylogeny Group website, the nitrogen-fixing clade contains a high number of actinorhizal plants. Not all plants in this clade are actinorhizal, however, media related to Rosids at Wikimedia Commons

Rosales
–
Rosales is an order of flowering plants. It is sister to a clade consisting of Fagales and Cucurbitales and it contains about 7700 species, distributed into about 260 genera. Rosales comprise nine families, the family being the rose family. The largest of these families are Rosaceae and Urticaceae, the order Rosales is divided into three clades that have never been assigned a taxonomic rank. The basal clade consists of the family Rosaceae, another clade consists of four families, including Rhamnaceae, the order Rosales is strongly supported as monophyletic in phylogenetic analyses of DNA sequences, such as those carried out by members of the Angiosperm Phylogeny Group. In their APG III system of plant classification, they defined Rosales as consisting of the nine families listed in the box on the right. The relationships of these families were uncertain until 2011, when they were resolved in a phylogenetic study based on two nuclear genes and ten chloroplast genes. In the classification system of Dahlgren the Rosales were in the superorder Rosiflorae, in the obsolete Cronquist system, the order Rosales was many times polyphyletic. It consisted of the family Rosaceae and 23 other families that are now placed in other orders

Moraceae
–
The Moraceae — often called the mulberry family or fig family — are a family of flowering plants comprising about 38 genera and over 1180 species. Most are widespread in tropical and subtropical regions, less so in temperate climates, included are well-known plants such as the fig, banyan, breadfruit, mulberry, and Osage-orange. The flowers of Moraceae are often pseudanthia, cecropia, which has variously been placed in Moraceae, Urticaceae, or their own family, Cecropiaceae, is now included in Urticaceae. Dioecy appears to be the state in Moraceae. Monoecy has evolved independently at least four times within the family, Moraceae comprises the following, Modern molecular phylogenetics suggest the following relationships, Moraceae in L. Watson and M. J. Dallwitz

Artocarpus
–
Artocarpus is a genus of approximately 60 trees and shrubs of Southeast Asian and Pacific origin, belonging to the mulberry family, Moraceae. All Artocarpus species are trees or shrubs that are composed of leaves, twigs. The fauna type is monoecious and produces flowers, furthermore. The plants produce small, greenish, female flowers grow on short. Following pollination, the flowers grow into a fruit. The stipulated leaves vary from small and entire to large and lobed, with the leaves of the species A. altilis ending in long. The name Artocarpus is derived from the Greek words artos and karpos and this name was coined by Johann Reinhold Forster and J. Georg Adam Forster, a father-and-son team of botanists aboard the HMS Resolution on James Cooks second voyage. It is maintained as a conserved name, several species in the genus bear edible fruit and are commonly cultivated, breadfruit, cempedak, jackfruit, kwai muk, lakoocha, pudau, anjily, chaplaish, and marang. Breadfruit and jackfruit are cultivated widely in the tropical Southeast Asia, other species are cultivated locally for their timber, fruit or edible seeds. Anjily, A. hirsutus, is grown for fruit and timber in the Western Ghats, subgenus Pseudojaca, Perianth is entirely connate. Subgenus Pseudojaca is allied to the genus Prainea, and some researchers treat this taxon as a subgenus of Artocarpus.

Binomial nomenclature
–
Such a name is called a binomial name, a binomen, binominal name or a scientific name, more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs, for example, humans belong to the genus Homo and within this genus to the species Homo sapiens. The formal introduction of system of naming species is credited to Carl Linnaeus. But Gaspard Bauhin, in as early as 1623, had introduced in his book Pinax theatri botanici many names of genera that were adopted by Linnaeus. Although the general principles underlying binomial nomenclature are common to these two codes, there are differences, both in the terminology they use and in their precise rules. Similarly, both parts are italicized when a binomial name occurs in normal text, thus the binomial name of the annual phlox is now written as Phlox drummondii. In scientific works, the authority for a name is usually given, at least when it is first mentioned. In zoology Patella vulgata Linnaeus,1758, the original name given by Linnaeus was Fringilla domestica, the parentheses indicate that the species is now considered to belong in a different genus. The ICZN does not require that the name of the person who changed the genus be given, nor the date on which the change was made, in botany Amaranthus retroflexus L. – L. is the standard abbreviation used in botany for Linnaeus. – Linnaeus first named this bluebell species Scilla italica, Rothmaler transferred it to the genus Hyacinthoides, the ICN does not require that the dates of either publication be specified. Prior to the adoption of the binomial system of naming species. Together they formed a system of polynomial nomenclature and these names had two separate functions. First, to designate or label the species, and second, to be a diagnosis or description, such polynomial names may sometimes look like binomials, but are significantly different. For example, Gerards herbal describes various kinds of spiderwort, The first is called Phalangium ramosum, Branched Spiderwort, is aptly termed Phalangium Ephemerum Virginianum, Soon-Fading Spiderwort of Virginia. The Latin phrases are short descriptions, rather than identifying labels, the Bauhins, in particular Caspar Bauhin, took some important steps towards the binomial system, by pruning the Latin descriptions, in many cases to two words. The adoption by biologists of a system of binomial nomenclature is due to Swedish botanist and physician Carl von Linné. It was in his 1753 Species Plantarum that he first began using a one-word trivial name together with a generic name in a system of binomial nomenclature. This trivial name is what is now known as an epithet or specific name

Sydney C. Parkinson
–
Sydney Parkinson was a Scottish Quaker, botanical illustrator and natural history artist. Parkinson was employed by Joseph Banks to travel with him on James Cooks first voyage to the Pacific in 1768, Parkinson made nearly a thousand drawings of plants and animals collected by Banks and Daniel Solander on the voyage. He had to work in conditions, living and working in a small cabin surrounded by hundreds of specimens. In Tahiti he was plagued by swarms of flies which ate the paint as he worked and he died at sea on the way to Cape Town of dysentery contracted at Princes Island off the western end of Java. Banks paid his salary to his brother. Parkinson is commemorated in the common and scientific name of the Parkinsons petrel Procellaria parkinsoni, the great Florilegium of his work was finally published in 1988 by Alecto Historical Editions in 35 volumes and has since been digitized by the Natural History Museum in London.

Synonym (taxonomy)
–
For example, Linnaeus was the first to give a scientific name to the Norway spruce, which he called Pinus abies. This name is no longer in use, it is now a synonym of the current scientific name which is Picea abies, unlike synonyms in other contexts, in taxonomy a synonym is not interchangeable with the name of which it is a synonym. In taxonomy, synonyms are not equals, but have a different status, for any taxon with a particular circumscription, position, and rank, only one scientific name is considered to be the correct one at any given time. A synonym cannot exist in isolation, it is always an alternative to a different scientific name, given that the correct name of a taxon depends on the taxonomic viewpoint used a name that is one taxonomists synonym may be another taxonomists correct name. Synonyms may arise whenever the same taxon is described and named more than once, independently. They may also arise when existing taxa are changed, as when two taxa are joined to one, a species is moved to a different genus. To the general user of scientific names, in such as agriculture, horticulture, ecology, general science. A synonym is a name that was used as the correct scientific name but which has been displaced by another scientific name. Thus Oxford Dictionaries Online defines the term as a name which has the same application as another. In handbooks and general texts, it is useful to have mentioned as such after the current scientific name. Synonyms used in this way may not always meet the strict definitions of the synonym in the formal rules of nomenclature which govern scientific names. Changes of scientific name have two causes, they may be taxonomic or nomenclatural, a name change may be caused by changes in the circumscription, position or rank of a taxon, representing a change in taxonomic, scientific insight. A name change may be due to purely nomenclatural reasons, that is, based on the rules of nomenclature, the earliest such name is called the senior synonym, while the later name is the junior synonym. One basic principle of zoological nomenclature is that the earliest correctly published name, synonyms are important because if the earliest name cannot be used, then the next available junior synonym must be used for the taxon. Objective synonyms refer to taxa with the type and same rank. For example, John Edward Gray published the name Antilocapra anteflexa in 1855 for a species of pronghorn, however, it is now commonly accepted that his specimen was an unusual individual of the species Antilocapra americana published by George Ord in 1815. Ords name thus takes precedence, with Antilocapra anteflexa being a subjective synonym. Objective synonyms are common at the level of genera, because for various reasons two genera may contain the type species, these are objective synonyms

Tree
–
In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. Trees are not a group but include a variety of plant species that have independently evolved a woody trunk. In looser senses, the palms, the tree ferns, bananas. Trees tend to be long-lived, some reaching several thousand years old, the tallest known tree, a coast redwood named Hyperion, stands 115.6 m high. Trees have been in existence for 370 million years and it is estimated that there are just over 3 trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk and this trunk typically contains woody tissue for strength, and vascular tissue to carry materials from one part of the tree to another. For most trees it is surrounded by a layer of bark which serves as a protective barrier, below the ground, the roots branch and spread out widely, they serve to anchor the tree and extract moisture and nutrients from the soil. Above ground, the divide into smaller branches and shoots. The shoots typically bear leaves, which light energy and convert it into sugars by photosynthesis, providing the food for the trees growth. Flowers and fruit may also be present, but some trees, such as conifers, instead have pollen cones and seed cones, others, such as tree ferns, trees play a significant role in reducing erosion and moderating the climate. They remove carbon dioxide from the atmosphere and store large quantities of carbon in their tissues, trees and forests provide a habitat for many species of animals and plants. Tropical rainforests are one of the most biodiverse habitats in the world, trees provide shade and shelter, timber for construction, fuel for cooking and heating, and fruit for food as well as having many other uses. In parts of the world, forests are shrinking as trees are cleared to increase the amount of available for agriculture. Because of their longevity and usefulness, trees have always revered, with sacred groves in various cultures. Although tree is a term of common parlance, there is no universally recognised precise definition of what a tree is, either botanically or in common language. In its broadest sense, a tree is any plant with the form of an elongated stem, or trunk. Trees are also defined by height, with smaller plants from 0.5 to 10 m being called shrubs

Morus (plant)
–
Morus, a genus of flowering plants in the family Moraceae, comprises 10–16 species of deciduous trees commonly known as mulberries, growing wild and under cultivation in many temperate world regions. The closely related genus Broussonetia is also known as mulberry, notably the paper mulberry. Mulberries are fast-growing when young, but soon become slow-growing and rarely exceed 10–15 metres tall, the leaves are alternately arranged, simple and often lobed and serrated on the margin. Lobes are more common on juvenile shoots than on mature trees, the trees can be monoecious or dioecious. The mulberry fruit is a fruit, approximately 2 to 3 cm long. Immature fruits are white, green, or pale yellow, in most species the fruits turn pink and then red while ripening, then dark purple or black, and have a sweet flavor when fully ripe. The fruits of the white-fruited cultivar are white when ripe, the fruit of this cultivar is also sweet, the taxonomy of Morus is complex and disputed. Morus classification is further complicated by widespread hybridisation, wherein the hybrids are fertile. Jams and sherbets are often made from the fruit in this region, black mulberry was imported to Britain in the 17th century in the hope that it would be useful in the cultivation of silkworms. It was much used in medicine, especially in the treatment of ringworm. Mulberries are also widespread in Greece, particularly in the Peloponnese, mulberries can be grown from seed, and this is often advised as seedling-grown trees are generally of better shape and health, but they are most often planted from large cuttings which root readily. The mulberry plants which are allowed to grow tall with a height of 5–6 feet from ground level. Usually, the plantation is raised and in formation with a spacing of 6 feet ×6 feet, or 8 feet ×8 feet, as plant to plant. The plants are usually pruned once a year during the season to a height of 5–6 feet. The leaves are harvested three or four times a year by a leaf-picking method under rain-fed or semiarid conditions, depending on the monsoon, the tree branches pruned during the fall season are cut and used to make durable baskets supporting agriculture and animal husbandry. Some North American cities have banned the planting of mulberries because of the amounts of pollen they produce. In actuality, only the male mulberry trees produce pollen, this light-weight pollen can be inhaled deeply into the lungs, conversely, female mulberry trees produce all-female flowers, which draw pollen and dust from the air. Because of this feature, all-female mulberry trees have an OPALS allergy scale rating of just 1

Jackfruit
–
The jackfruit, also known as jack tree, jakfruit, or sometimes simply jack or jak, is a species of tree in the fig, mulberry, and breadfruit family. It is native to parts of South and Southeast Asia and is believed to have originated in the rain forests of the Western Ghats in the Indian subcontinent. The jackfruit tree is suited to tropical lowlands, and its fruit is the largest tree-borne fruit, reaching as much as 35 kg in weight,90 cm in length. The jackfruit tree can produce about 100 to 200 fruits in a year, the jackfruit is a multiple fruit, composed of hundreds to thousands of individual flowers, and it is the fleshy petals that are eaten. The jackfruit tree is a cultivated and popular food item throughout the tropical regions of the world. Jackfruit is the fruit of Bangladesh. The word jackfruit comes from Portuguese jaca, which in turn is derived from the Malayalam language term chakka. When the Portuguese arrived in India at Kozhikode on the Malabar Coast in 1498, henry Yule translated the book in Jordanus Catalanis Mirabilia descripta, the wonders of the East. The common English name jackfruit was used by physician and naturalist Garcia de Orta in his 1563 book Colóquios dos simples e drogas da India. Centuries later, botanist Ralph Randles Stewart suggested it was named after William Jack, a Scottish botanist who worked for the East India Company in Bengal, Sumatra, the jackfruit has played a significant role in Indian agriculture for centuries. Archeological findings in India have revealed that jackfruit was cultivated in India 3000 to 6000 years ago and it has also been widely cultivated in southeast Asia. Stingless bees such as Tetragonula iridipennis are jackfruit pollinators, and as such, the jackfruit also provides a potential solution to countries facing problems with food security, such as in several countries of Africa. In terms of taking care of the plant, minimal pruning is required, in addition, twigs bearing fruit must be twisted or cut down to the trunk to induce growth for the next season. Branches may also be cut off every three to four years to maintain its productivity, Jackfruit have a distinctive sweet and fruity aroma. A fully ripe and unopened jackfruit is known to emit an aroma, with the inside of the fruit described as smelling of pineapple. After roasting, the seeds may be an alternative to chocolate aroma. The flesh of the jackfruit is starchy and fibrous and is a source of dietary fiber, the flavor is comparable to a combination of apple, pineapple, mango, and banana. Varieties are distinguished according to characteristics of the fruits flesh, Jackfruit is commonly used in South and Southeast Asian cuisines

Oceania
–
Oceania, also known as Oceanica, is a region centred on the islands of the tropical Pacific Ocean. The term is used more specifically to denote a continent comprising Australia. The term was coined as Océanie circa 1812 by geographer Conrad Malte-Brun, the word Océanie is a French word derived from the Latin word oceanus, and this from the Greek word ὠκεανός, ocean. Natives and inhabitants of this region are called Oceanians or Oceanicans, as an ecozone, Oceania includes all of Micronesia, Fiji, and all of Polynesia except New Zealand. New Zealand, along with New Guinea and nearby islands, part of the Philippine islands, Australia, the Solomon Islands, Vanuatu, in geopolitical terms, however, New Zealand, the Solomon Islands, Vanuatu and New Caledonia are almost always considered part of Oceania. Australia and Papua New Guinea are usually considered part of Oceania along with the Maluku Islands, puncak Jaya in Papua is often considered the highest peak in Oceania. Oceania was originally conceived as the lands of the Pacific Ocean and it comprised four regions, Polynesia, Micronesia, Malaysia, and Melanesia. The area extends to Sumatra in the west, the Bonin Islands in the northwest, the Hawaiian Islands in the northeast, Rapa Nui and Sala y Gómez Island in the east, and Macquarie Island in the south. Not included are the Pacific islands of Taiwan, the Ryukyu Islands and the Japanese archipelago, all on the margins of Asia, and the Aleutian Islands of North America. The islands at the extremes of Oceania are Bonin, a politically integral part of Japan, Hawaii, a state of the United States. There is also a geographic definition that excludes land on the Sunda Plate. Biogeographically, Oceania is used as a synonym for either the Australasian ecozone or the Pacific ecozone, Oceania is one of eight terrestrial ecozones, which constitute the major ecological regions of the planet. The Oceania ecozone includes all of Micronesia, Fiji, and all of Polynesia except New Zealand, New Zealand, New Guinea, Melanesia apart from Fiji, and Australia constitute the separate Australasian ecozone. The Malay Archipelago is part of the Indomalaya ecozone, related to these concepts are Near Oceania, that part of western Island Melanesia which has been inhabited for tens of millennia, and Remote Oceania which is more recently settled. The term is used to denote a continent comprising Australia. New Zealand forms the corner of the Polynesian Triangle. Its indigenous Māori constitute one of the cultures of Polynesia. It is also, however, considered part of Australasia, the history of Oceania in the medieval period was synonymous with the history of the indigenous peoples of Australasia, Micronesia, Melanesia, Polynesia

DNA profiling
–
DNA profiling is a forensic technique used to identify individuals by characteristics of their DNA. A DNA profile is a set of DNA variations that is very likely to be different in all unrelated individuals. DNA profiling should not be confused with full genome sequencing, DNA fingerprinting has also been widely used in the study of animal and floral populations and has revolutionized the fields of zoology, botany, and agriculture. Although 99. 9% of human DNA sequences are the same in every person, enough of the DNA is different that it is possible to one individual from another. DNA profiling uses repetitive sequences that are variable, called variable number tandem repeats, in particular short tandem repeats, also known as microsatellites. VNTR loci are very similar between closely related individuals, but are so variable that unrelated individuals are extremely unlikely to have the same VNTRs. The modern process of DNA profiling was developed in 1984 by Sir Alec Jeffreys while working in the Department of Genetics at the University of Leicester, developed by Professor of Genetics Sir Alec Jeffreys, the process begins with a sample of an individuals DNA. A common method of collecting a sample is the use of a buccal swab. Samples obtained from blood relatives can provide an indication of an individuals profile, a reference sample is then analyzed to create the individuals DNA profile using one of a number of techniques, discussed below. The DNA profile is then compared against another sample to determine there is a genetic match. The first methods for finding out genetics used for DNA profiling involved RFLP analysis, DNA is collected from cells, such as a blood sample, and cut into small pieces using a restriction enzyme. This generates thousands of DNA fragments of differing sizes as a consequence of variations between DNA sequences of different individuals, the fragments are then separated on the basis of size using gel electrophoresis. The separated fragments are transferred to a nitrocellulose or nylon filter. The DNA fragments within the blot are permanently fixed to the filter, radiolabeled probe molecules are then added that are complementary to sequences in the genome that contain repeat sequences. These repeat sequences tend to vary in length among different individuals and are called variable number tandem repeat sequences or VNTRs, the probe molecules hybridize to DNA fragments containing the repeat sequences and excess probe molecules are washed away. The blot is then exposed to an X-ray film, fragments of DNA that have bound to the probe molecules appear as dark bands on the film. The Southern blot technique is laborious, and requires large amounts of undegraded sample DNA, also, Karl Browns original technique looked at many minisatellite loci at the same time, increasing the observed variability, but making it hard to discern individual alleles. These early techniques have been supplanted by PCR-based assays, developed by Kary Mullis in 1983, a process was reported by which specific portions of the sample DNA can be amplified almost indefinitely

New Guinea
–
New Guinea is a large Island in the South West Pacific region. It is the worlds second-largest island, after Greenland, covering an area of 785,753 km2. The island is divided between two countries, Papua New Guinea to the east, and Indonesia to the west, the island has been known by various names. The name Papua was used to refer to parts of the island before contact with the West and its etymology is unclear, one theory states that it is from Tidore, the language used by the Sultanate of Tidore, which controlled parts of the islands coastal region. The name came from papo and ua, which means not united or, ploeg reports that the word papua is often said to derive from the Malay word papua or pua-pua, meaning frizzly-haired, referring to the highly curly hair of the inhabitants of these areas. When the Portuguese and Spanish explorers arrived in the island via the Spice Islands, when the Dutch colonized it as part of Netherlands East Indies, they called it Nieuw Guinea. The name Irian was used in the Indonesian language to refer the island and Indonesian province, the name was promoted in 1945 by Marcus Kaisiepo, brother of the future governor Frans Kaisiepo. It is taken from the Biak language of Biak Island, and means to rise and this name of Irian is the name used in the Biak language and other languages such as Serui, Merauke and Waropen. The name was used until 2001, when the name Papua was again used for the island, the name Irian, which was originally favored by natives, is now considered to be a name imposed by the authority of Jakarta. New Guinea is an island to the north of Australia, and it is isolated by the Arafura Sea to the west and the Torres Strait and Coral Sea to the east. A spine of east–west mountains, the New Guinea Highlands, dominates the geography of New Guinea, stretching over 1,600 km from the head to the tail of the island. The western half of the island of New Guinea contains the highest mountains in Oceania, rising up to 4,884 m high, the tree line is around 4,000 m elevation and the tallest peaks contain permanent equatorial glaciers—which have been retreating since at least 1936. Various other smaller mountain ranges occur both north and west of the central ranges, except in high elevations, most areas possess a warm humid climate throughout the year, with some seasonal variation associated with the northeast monsoon season. At 4,884 metres, Puncak Jaya makes New Guinea the worlds fourth highest landmass, Puncak Mandala, located in Papua, is the second highest peak on the island at 4,760 metres. Puncak Trikora, also in Papua, is 4,750 metres, mount Wilhelm is the highest peak on the PNG side of the border at 4,509 metres. Its granite peak is the highest point of the Bismarck Range, mount Giluwe 4,368 metres is the second highest summit in PNG. It is also the highest volcanic peak in Oceania, another major habitat feature is the vast southern and northern lowlands. Stretching for hundreds of kilometres, these include lowland rainforests, extensive wetlands, savanna grasslands, the southern lowlands are the site of Lorentz National Park, also a UNESCO World Heritage Site

Malay Archipelago
–
The Malay Archipelago is the archipelago between mainland Indochina and Australia. It has also called the Malay World, Indo-Australian Archipelago, East Indies, Nusantara, Spices Archipelago. The name was taken from the 19th-century European concept of a Malay race, situated between the Indian and Pacific Oceans, the group of over 25,000 islands is the largest archipelago by area, and fourth by number of islands in the world. It includes Brunei, Singapore, East Malaysia, Indonesia, the Philippines, the island of New Guinea is usually excluded from definitions of the Malay Archipelago, although the Indonesian western portion of the island may be included. The term is synonymous with maritime Southeast Asia. The term was derived from the European concept of a Malay race, which referred to the people who inhabited what is now Brunei, Singapore, Malaysia, Indonesia, the Philippines and East Timor. The racial concept was proposed by European explorers based on their observations of the influence of the ethnic Malay empire, Srivijaya, the 19th-century naturalist Alfred Wallace used the term Malay Archipelago as the title of his influential book documenting his studies in the region. Wallace also referred to the area as the Indian Archipelago and the Indo-Australian Archipelago and he included within the region the Solomon Islands and the Malay Peninsula due to physiographic similarities. The archipelago was called the East Indies from the late 16th century and it is still sometimes referred to as such, but broader usages of the East Indies term had included Indochina and the Indian subcontinent. The area is called Nusantara in the Indonesian and Malaysian languages, the area is also referred to as the Indonesian archipelago. The term maritime Southeast Asia is largely synonymous, covering both the islands in Southeast Asia and nearby communities, such as those found on the Malay Peninsula. The land and sea area of the archipelago exceeds 2 million km2, the more than 25,000 islands of the archipelago comprise many smaller archipelagoes. Geologically the archipelago is one of the most active regions in the world. Tectonic uplifts have produced large mountains, including the highest in Mount Kinabalu in Sabah, Malaysia, with a height of 4,095.2 m and Puncak Jaya on Papua, Indonesia at 4,884 m. Other high mountains in the archipelago include Puncak Mandala, Indonesia at 4,760 m and Puncak Trikora, Indonesia, the climate throughout the archipelago is tropical, owing to its position on the equator. Wallace used the term Malay Archipelago as the title of his influential book documenting his studies in the region and he proposed what would come to be known as the Wallace Line, a boundary that separated the flora and fauna of Asia and Australia. The ice age boundary was formed by the deep water straits between Borneo and Sulawesi, and through the Lombok Strait between Bali and Lombok and this is now considered the western border of the Wallacea transition zone between the zoogeographical regions of Asia and Australia. The zone has a mixture of species of Asian and Australian origin, over 380 million people live in the region, with the most populated islands being Java, Luzon, Sumatra, Taiwan, Mindanao and Sri Lanka

Micronesia
–
Micronesia is a subregion of Oceania, comprising thousands of small islands in the western Pacific Ocean. It has a cultural history with two other island regions, Polynesia to the east and Melanesia to the south. The region has a marine climate, and is part of the Oceania ecozone. There are four main archipelagos along with numerous outlying islands, Micronesia is divided politically among several sovereign countries. One of these is the Federated States of Micronesia, which is often called Micronesia for short and is not to be confused with the overall region, Micronesia began to be settled several millennia ago, although there are competing theories about the origin and arrival of the first settlers. The earliest known contact with Europeans occurred in 1521, when Ferdinand Magellan reached the Marianas, the coinage of the term Micronesia is usually attributed to Jules Dumont dUrvilles usage in 1832, however Domeny de Rienzi had used the term a year previously. Micronesia is a region that includes approximately 2100 islands, with a land area of 2,700 km2, the largest of which is Guam. The total ocean area within the perimeter of the islands is 7,400,000 km2, there are four main island groups in Micronesia, the Caroline Islands the Gilbert Islands the Mariana Islands the Marshall Islands Plus the island country of Nauru. The Caroline Islands are a widely scattered archipelago consisting of about 500 small coral islands, north of New Guinea, the Gilbert Islands are a chain of sixteen atolls and coral islands, arranged in an approximate north-to-south line. In a geographical sense, the equator serves as the line between the northern Gilbert Islands and the southern Gilbert Islands. The Republic of Kiribati contains all of the Gilberts, as well as the island of Tarawa, the Mariana Islands are an arc-shaped archipelago made up by the summits of fifteen volcanic mountains. Guam and the Northern Marianas are two of the five remaining U. S, the Marshall Islands is an island country, located north of Nauru and Kiribati, east of the Federated States of Micronesia, and south of the U. S. territory of Wake Island. The country consists of 29 low-lying atolls and 5 isolated islands, comprising 1,156 individual islands, the atolls and islands form two groups, the Ratak Chain and the Ralik Chain. All the islands in the chain are part of the Republic of the Marshall Islands, having few natural resources, the islands wealth is based on a service economy, as well as some fishing and agriculture. Of the 29 atolls,24 of them are inhabited, Bikini Atoll is an atoll in the Marshall Islands. There are 23 islands in the Bikini Atoll, the islands of Bokonijien, Aerokojlol, and Nam were vaporized during nuclear tests that occurred there. The islands are composed of low coral limestone аnd sand, the average elevation is only about 2.1 metres above low tide level. Nauru is an island country in the southwestern Pacific Ocean,42 km south of the Equator, listed as the worlds smallest republic

Central America
–
Central America is the southernmost, isthmian portion of the North American continent, which connects with South America on the southeast. Central America is bordered by Mexico to the north, Colombia to the southeast, the Caribbean Sea to the east, Central America consists of seven countries, Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and Panama. The combined population of Central America is between 41,739,000 and 42,688,190, Central America is a part of the Mesoamerican biodiversity hotspot, which extends from northern Guatemala through to central Panama. Due to the presence of several active faults and the Central America Volcanic Arc. Volcanic eruptions and earthquakes occur frequently, these disasters have resulted in the loss of many lives. In the Pre-Columbian era, Central America was inhabited by the peoples of Mesoamerica to the north and west. Soon after Christopher Columbuss voyages to the Americas, the Spanish began to colonize the Americas, the seven states finally became independent autonomous states, beginning with Nicaragua, Honduras, Costa Rica, and Guatemala, followed by El Salvador, then Panama, and finally Belize. Middle America is usually thought to comprise Mexico to the north of the 7 states of Central America as well as Colombia, usually the whole of the Caribbean to the north-east and sometimes the Guyanas are also included. According to one source, the term Central America was used as a synonym for Middle America as recently as 1962, in Brazil, Central America comprises all countries between Mexico and Colombia, including those in the Caribbean. Mexico, in whole or in part, is included by British people. For the people living in the 5 countries formerly part of the Federal Republic of Central America there is a distinction between the Spanish language terms América Central and Centroamérica, in the Pre-Columbian era, the northern areas of Central America were inhabited by the indigenous peoples of Mesoamerica. Most notable among these were the Mayans, who had built numerous cities throughout the region, and the Aztecs, following Christopher Columbuss voyages to the Americas, the Spanish sent many expeditions to the region, and they began their conquest of Maya territory in 1523. Soon after the conquest of the Aztec Empire, Spanish conquistador Pedro de Alvarado commenced the conquest of northern Central America for the Spanish Empire. Beginning with his arrival in Soconusco in 1523, Alvarados forces systematically conquered and subjugated most of the major Maya kingdoms, including the Kiche, Tzutujil, Pipil, and the Kaqchikel. By 1528, the conquest of Guatemala was nearly complete, with only the Petén Basin remaining outside the Spanish sphere of influence, the last independent Maya kingdoms – the Kowoj and the Itza people – were finally defeated in 1697, as part of the Spanish conquest of Petén. In 1538, Spain established the Real Audiencia of Panama, which had jurisdiction over all land from the Strait of Magellan to the Gulf of Fonseca. This entity was dissolved in 1543, and most of the territory within Central America then fell under the jurisdiction of the Audiencia Real de Guatemala. This area included the current territories of Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and the Mexican state of Chiapas, the president of the Audiencia, which had its seat in Antigua Guatemala, was the governor of the entire area

South America
–
South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It may also be considered a subcontinent of the Americas, which is the used in nations that speak Romance languages. The reference to South America instead of other regions has increased in the last decades due to changing geopolitical dynamics. It is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean, North America and it includes twelve sovereign states, a part of France, and a non-sovereign area. In addition to this, the ABC islands of the Kingdom of the Netherlands, Trinidad and Tobago, South America has an area of 17,840,000 square kilometers. Its population as of 2005 has been estimated at more than 371,090,000, South America ranks fourth in area and fifth in population. Brazil is by far the most populous South American country, with more than half of the population, followed by Colombia, Argentina, Venezuela. In recent decades Brazil has also concentrated half of the regions GDP and has become a first regional power, most of the population lives near the continents western or eastern coasts while the interior and the far south are sparsely populated. Most of the continent lies in the tropics, the continents cultural and ethnic outlook has its origin with the interaction of indigenous peoples with European conquerors and immigrants and, more locally, with African slaves. Given a long history of colonialism, the majority of South Americans speak Portuguese or Spanish. South America occupies the portion of the Americas. The continent is delimited on the northwest by the Darién watershed along the Colombia–Panama border. Almost all of mainland South America sits on the South American Plate, South Americas major mineral resources are gold, silver, copper, iron ore, tin, and petroleum. These resources found in South America have brought high income to its countries especially in times of war or of rapid growth by industrialized countries elsewhere. However, the concentration in producing one major export commodity often has hindered the development of diversified economies and this is leading to efforts to diversify production to drive away from staying as economies dedicated to one major export. South America is one of the most biodiverse continents on earth, South America is home to many interesting and unique species of animals including the llama, anaconda, piranha, jaguar, vicuña, and tapir. The Amazon rainforests possess high biodiversity, containing a proportion of the Earths species. Brazil is the largest country in South America, encompassing around half of the land area

Caribbean
–
The Caribbean is a region that consists of the Caribbean Sea, its islands and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, situated largely on the Caribbean Plate, the region comprises more than 700 islands, islets, reefs and cays. These islands generally form island arcs that delineate the eastern and northern edges of the Caribbean Sea, in a wider sense, the mainland countries of Belize, Guyana, Suriname and French Guiana are often included due to their political and cultural ties with the region. Geopolitically, the Caribbean islands are usually regarded as a subregion of North America and are organized into 30 territories including sovereign states, overseas departments, and dependencies. From December 15,1954, to October 10,2010, there was a known as the Netherlands Antilles composed of five states. The West Indies cricket team continues to represent many of those nations, the region takes its name from that of the Caribs, an ethnic group present in the Lesser Antilles and parts of adjacent South America at the time of the Spanish conquest. The two most prevalent pronunciations of Caribbean are KARR-ə-BEE-ən, with the accent on the third syllable. The former pronunciation is the older of the two, although the variant has been established for over 75 years. It has been suggested that speakers of British English prefer KARR-ə-BEE-ən while North American speakers more typically use kə-RIB-ee-ən, usage is split within Caribbean English itself. The word Caribbean has multiple uses and its principal ones are geographical and political. The Caribbean can also be expanded to include territories with strong cultural and historical connections to slavery, European colonisation, the United Nations geoscheme for the Americas accords the Caribbean as a distinct region within the Americas. Physiographically, the Caribbean region is mainly a chain of islands surrounding the Caribbean Sea, to the north, the region is bordered by the Gulf of Mexico, the Straits of Florida and the Northern Atlantic Ocean, which lies to the east and northeast. To the south lies the coastline of the continent of South America, politically, the Caribbean may be centred on socio-economic groupings found in the region. For example, the known as the Caribbean Community contains the Co-operative Republic of Guyana. Bermuda and the Turks and Caicos Islands, which are in the Atlantic Ocean, are members of the Caribbean Community. The Commonwealth of the Bahamas is also in the Atlantic and is a member of the Caribbean Community. According to the ACS, the population of its member states is 227 million people. The geography and climate in the Caribbean region varies, Some islands in the region have relatively flat terrain of non-volcanic origin and these islands include Aruba, Barbados, Bonaire, the Cayman Islands, Saint Croix, the Bahamas, and Antigua

Staple food
–
The staple food of a specific society may be eaten as often as every day or every meal, and most people live on a diet based on just a small number of staples. Typical examples of staples include tubers and roots, and grains, legumes, such nonperishable foods are the only possible staples during seasons of shortage, such as dry seasons or cold temperate winters, against which times harvests have been stored. During seasons of plenty, wider choices of foods may be available. Most staple plant foods are derived either from cereals such as wheat, barley, rye, maize, or rice, or starchy tubers or root vegetables such as potatoes, yams, taro, arrowroot, other staple foods include pulses, sago, and fruits. Staple foods may contain, sorghum, olive oil, coconut oil. Most staples are plant materials, but in some fishing is the primary source of nutrition. Of the more than 50,000 edible plant species in the world, although there are over 10,000 species in the cereal family, just a few have been widely cultivated over the past 2,000 years. The staple food in different parts of the world is a function of weather patterns, local terrain, farming constraints, acquired tastes, for example, the main energy source staples in the average African diet are cereals, roots and tubers and animal products. In Western Europe the main staples in the diet are animal products, cereals and roots. Regional staples include rye, soybeans, barley, oats and teff, just 15 crop plants provide 90 percent of the worlds food energy intake, with rice, maize and wheat comprising two-thirds of human food consumption. The three are the staples of about 80% of the population, and rice feeds almost half of humanity. Roots and tubers, meanwhile, are important staples for over 1 billion people in the developing world, roots and tubers are high in carbohydrates, calcium and vitamin C but low in protein. Cassava root is a staple food in the developing world. With economic development and free trade, many countries have shifted away from low-nutrient-density staple foods to higher-nutrient-density staples, despite this trend, there is growing recognition of the importance of traditional staple crops in nutrition. Efforts are underway to identify better strains with superior nutrition, disease resistance, some foods like quinoa—a pseudocereal grain that originally came from the Andes—were also staple foods centuries ago. Oca, ulluco and amaranth seed are other foods claimed to be staples in Andean history, pemmican was a staple of the Plains Indians of North America. In 2010, the consumption of speciality grains such as quinoa was very small compared to other staples such as rice, wheat. These grains, once popular but then forgotten, are being reevaluated and reintroduced, most staple food is produced using modern and conventional farming practices

Seamanship
–
Seamanship is the art of operating a ship or boat. The degree of knowledge needed within these areas is dependent upon the nature of the work, navigation is the art and science of safely and efficiently directing the movements of a vessel from one point to another. Piloting uses water depth and visible references, while dead reckoning uses courses and distances from the last known position, more than just finding a vessels present location, safe navigation includes predicting future location, route planning and collision avoidance. Nautical navigation in western nations, like air navigation, is based on the nautical mile, navigation also includes electronics such as GPS and Loran. Celestial navigation involves taking sights by sextant on the planets, moon, stars, sun and using the data with a nautical almanac, accurate time information is also needed. After nautical dusk, navigation at sea referencing the horizon is no longer possible, a fundamental skill of professional seamanship is being able to maneuver a vessel with accuracy and precision. Unlike vehicles on land, a ship afloat is subject to the movements of the air around it, another complicating factor is the mass of a ship that has to be accounted for when stopping and starting. Ship-handling is about arriving and departing a berth or buoy, maneuvering in confined channels and harbours and in proximity to other ships, two other types of operations, berthing alongside another ship and replenishment at sea, are occasionally included. Fundamental to low-speed maneuvering is an understanding of the configuration and handedness of the propeller, thus to put the vessel into astern mode the rudder can be rotated through 180 degrees without altering the speed and direction of the engine. Since with the propeller or rudder configuration the propeller is designed to operate at maximum efficiency when going ahead. But with the Kortz Nozzle, the ahead and astern thrust is the same, most commercial vessels in excess of size limits determined by local authorities are handled in confined areas by a marine pilot. Marine pilots are seafarers with extensive seafaring experience and are usually qualified master mariners who have trained as expert ship-handlers. These pilots are conversant with all types of vessel and propulsion systems, as well as handling ships of all sizes in all weather and they are also experts in the geographical areas they work. In most countries, the pilot takes over the conduct of the navigation from the ship master and this means that the master and crew should adhere to the pilots orders in respect of the safe navigation of the vessel when in a compulsory pilotage area. The master may with good cause resume conduct of the vessels navigation, however this should never be done lightly. In situations where the pilot is an advisor even though he has the con, the master, upon realizing there is a dangerous situation developing, must take such action as to avoid an accident or at least to minimize the damage from one that cant be avoided. In some countries and areas, the role is as an advisor. However, in practice, they are likely to have the conduct of the vessel, especially on larger ships using tug boats to assist

Melanesia
–
Melanesia is a subregion of Oceania extending from New Guinea island in the southwestern Pacific Ocean to the Arafura Sea, and eastward to Fiji. The region includes the four countries of Vanuatu, the Solomon Islands, Fiji, the concept among Europeans of Melanesia as a distinct region evolved gradually over time as their expeditions mapped and explored the Pacific. Early European explorers noted the differences among groups of Pacific Islanders. In the first half of the nineteenth century Jean Baptiste Bory de Saint-Vincent, over time, however, Europeans increasingly viewed Melanesia as a distinct cultural, rather than racial, area. Scholars and other commentators disagreed on its boundaries, which were fluid, in the nineteenth century Robert Codrington, a British missionary, produced a series of monographs on the Melanesians based on his long-time residence in the region. He did not include the islands of New Guinea because only some of its people were Melanesians, like Bory de Saint-Vincent, he excluded Australia from Melanesia. It was in works that Codrington introduced the cultural concept of mana to the West. Uncertainty about the delineation and definition of the region continues, the scholarly consensus now includes New Guinea within Melanesia. Ann Chowning wrote in her 1977 textbook on Melanesia that there is no agreement even among anthropologists about the geographical boundaries of Melanesia. In 1998 Paul Sillitoe wrote of Melanesia, it is not easy to define precisely, on geographical, cultural, biological, or any other grounds, where Melanesia ends and the neighbouring regions. It covers populations that have a linguistic, biological and cultural affinity – a certain ill-defined sameness. Both Sillitoe and Chowning include the island of New Guinea in the definition of Melanesia, most of the peoples in Melanesia have established independent countries, are admistered by France or have active independence movements. Many have recently taken up the term Melanesia as a source of identity, stephanie Lawson writes that the term moved from a term of denigration to one of affirmation, providing a positive basis for contemporary subregional identity as well as a formal organisation. For instance, the author Bernard Narokobi wrote about the Melanesian Way as a form of culture that could empower the people of this region. The concept is used in geopolitics. For instance, the Melanesian Spearhead Group preferential trade agreement is a trade treaty among Vanuatu, the Solomon Islands, Papua New Guinea. The people of Melanesia have a distinctive ancestry, the limit of this ancient migration was Sahul, the continent formed when Australia and New Guinea were united by a land bridge as a result of low sea levels. The first migration into Sahul came over 40,000 years ago, a further expansion into the eastern islands of Melanesia came much later, probably between 4000 B. C. and 3000 B. C

Polynesia
–
Polynesia is a subregion of Oceania, made up of over 1,000 islands scattered over the central and southern Pacific Ocean. The indigenous people who inhabit the islands of Polynesia are termed Polynesians and they share many similar traits including the language family, culture, and beliefs. Historically, they were experienced sailors who used stars to navigate at night, the term Polynesia was first used in 1756 by French writer Charles de Brosses, and originally applied to all the islands of the Pacific. In 1831, Jules Dumont dUrville proposed a restriction on its use during a lecture to the Geographical Society of Paris, historically, these islands have also been referred to as the South Sea Islands. Polynesia is characterized by an amount of land spread over a very large portion of the mid. Most Polynesian islands and archipelagos, including the Hawaiian Islands and Samoa, are composed of volcanic islands built by hotspots, New Zealand, Norfolk Island, and Ouvéa, the Polynesian outlier near New Caledonia, are the unsubmerged portions of the largely sunken continent of Zealandia. At first, the Pacific plate was subducted under the Australian plate, the Alpine Fault that traverses the South Island is currently a transform fault while the convergent plate boundary from the North Island northwards is called the Kermadec-Tonga Subduction Zone. The volcanism associated with subduction zone is the origin of the Kermadec. Out of approximately 300,000 or 310,000 square kilometres of land, over 270,000 km2 are within New Zealand, the Zealandia continent has approximately 3,600,000 km2 of continental shelf. The oldest rocks in the region are found in New Zealand and are believed to be about 510 million years old, the oldest Polynesian rocks outside of Zealandia are to be found in the Hawaiian Emperor Seamount Chain, and are 80 million years old. Polynesia is generally defined as the islands within the Polynesian Triangle, geographically, the Polynesian Triangle is drawn by connecting the points of Hawaii, New Zealand and Easter Island. The other main island groups located within the Polynesian Triangle are Samoa, Tonga, there are also small Polynesian settlements in Papua New Guinea, the Solomon Islands, the Caroline Islands, and in Vanuatu. An island group with strong Polynesian cultural traits outside of this triangle is Rotuma. The people of Rotuma have many common Polynesian traits but speak a non-Polynesian language, some of the Lau Islands to the southeast of Fiji have strong historic and cultural links with Tonga. However, in essence, Polynesia is a term referring to one of the three parts of Oceania. Some islands of Polynesian origin are outside the triangle that geographically defines the region. The Phoenix Islands and Line Islands, most of which are part of Kiribati, are geographically Polynesian islands, tracing Polynesian languages places their prehistoric origins in the Malay Archipelago, and ultimately, in Taiwan. Between about 3000 and 1000 BC speakers of Austronesian languages began spreading from Taiwan into Island Southeast Asia, there are three theories regarding the spread of humans across the Pacific to Polynesia

Sir Joseph Banks, 1st Baronet, GCB, PRS was a British naturalist, botanist and patron of the natural sciences. Banks made his name on the 1766 natural history expedition to Newfoundland and he took part in Captain James Cooks first great voyage, visiting Brazil, Tahiti, and, after 6 months in New Zealand, Australia, returning to immediate fame. He held the position of President of the Royal Society for over 41 years and he advised King George III on the Royal Botanic Gardens, Kew, and by sending botanists around the world to collect plants, he made Kew the worlds leading botanical gardens. He is credited with introducing the eucalyptus, acacia, and the named after him, Banksia. Approximately 80 species of plants bear his name and he was the leading founder of the African Association and a member of the Society of Dilettanti which helped to establish the Royal Academy. Banks was born on Argyle Street in London to William Banks, a wealthy Lincolnshire country squire and member of the House of Commons and he had a younger sister, Sarah Sophia Banks, born in 1744. Banks was educated at Harrow School from the age of 9 and at Eton College from 1756, as a boy, Banks enjoyed exploring the Lincolnshire countryside and developed a keen interest in nature, history and botany. When he was 17, he was inoculated with smallpox, but he became ill, in late 1760, he was enrolled as a gentleman-commoner at the University of Oxford. At Oxford, he matriculated at Christ Church, where his studies were focused on natural history rather than the classical curriculum. Determined to receive instruction, he paid the Cambridge botanist Israel Lyons to deliver a series of lectures at Oxford in 1764. Banks left Oxford for Chelsea in December 1763 and he continued to attend the university until 1764, but left that year without taking a degree. He began to make friends among the men of his day and to correspond with Carl Linnaeus. As Bankss influence increased, he became an adviser to King George III and urged the monarch to support voyages of discovery to new lands and he became a Freemason sometime before 1769. He made his name by publishing the first Linnean descriptions of the plants and animals of Newfoundland and his diary, describing his expedition to Newfoundland, was rediscovered recently in the Royal Geographical Society of South Australia. Banks also documented 34 species of birds, including the great auk, on 7 May, he noted a large number of penguins swimming around the ship on the Grand Banks, and a specimen he collected in Chateau Bay, Labrador, was later identified as the great auk. Banks was appointed to a joint Royal Navy/Royal Society scientific expedition to the south Pacific Ocean on HMS Endeavour and this was the first of James Cooks voyages of discovery in that region. Banks funded seven others to him, the Swedish naturalist Daniel Solander. The voyage went to Brazil, where Banks made the first scientific description of a now common garden plant, bougainvillea, and to other parts of South America

Tahiti
–
Tahiti is the largest island in the Windward group of French Polynesia, this overseas collectivity of the French Republic is sometimes referred to as a French overseas country. The island was formed from volcanic activity and is high and mountainous with surrounding coral reefs, the population is 183,645 inhabitants, making it the most populous island of French Polynesia and accounting for 68.5 percent of its total population. Tahiti is the economic, cultural and political centre of French Polynesia, the capital, Papeete, is located on the northwest coast with the only international airport in the region, Faaā International Airport, situated 5 km from the town centre. Tahiti was originally settled by Polynesians between 300 and 800 CE and they represent about 70 percent of the islands population with the rest made up of Europeans, Chinese and those of mixed heritage. The island was part of the Kingdom of Tahiti until its annexation by France in 1880, when it was proclaimed a colony of France, French is the only official language although the Tahitian language is widely spoken. Tahiti is the highest and largest island in French Polynesia lying close to Moorea island and it is located 4,400 kilometres south of Hawaii,7,900 km from Chile and 5,700 km from Australia. The island is 45 km across at its widest point and covers an area of 1,045 km2, the highest peak is Mont Orohena. Mount Roonui, or Mount Ronui in the southeast rises to 1,332 m, the island consists of two roughly round portions centred on volcanic mountains and connected by a short isthmus named after the small town of Taravao, situated there. The northwestern portion is known as Tahiti Nui, while the much smaller portion is known as Tahiti Iti or Taiarapū. Tahiti Nui is heavily populated along the coast, especially around the capital, the interior of Tahiti Nui is almost entirely uninhabited. Tahiti Iti has remained isolated, as its half is accessible only to those travelling by boat or on foot. The rest of the island is encircled by a road which cuts between the mountains and the sea. A scenic and winding road climbs past dairy farms and citrus groves with panoramic views. Tahitis landscape features lush rainforests and many rivers and waterfalls, including the Papenoo River on the side. November to April is the wet season, the wettest month of which is January with 13.2 in of rain in Papeetē, August is the driest with 1.9 inches. The average temperature ranges between 21 and 31 °C with little seasonal variation, the lowest and highest temperatures recorded in Papeete are 16 and 34 °C, respectively. The first Tahitians arrived from Southeast Asia in about 200 BCE and this hypothesis of an emigration from Southeast Asia is supported by a number of linguistic, biological and archaeological proofs. For example, the languages of Fiji and Polynesia all belong to the same Oceanic sub-group, Fijian-Polynesian, in 1769, for instance, James Cook mentions a great traditional ship in Tahiti that was 33 m long, and could be propelled by sail or paddles

HMS Endeavour
–
The navy renamed and commissioned her as His Majestys Bark the Endeavour. She departed Plymouth in August 1768, rounded Cape Horn, and she then set sail into the largely uncharted ocean to the south, stopping at the Pacific islands of Huahine, Bora Bora, and Raiatea to allow Cook to claim them for Great Britain. In September 1769, she anchored off New Zealand, the first European vessel to reach the islands since Abel Tasmans Heemskerck 127 years earlier. In April 1770, Endeavour became the first ship to reach the east coast of Australia, Endeavour then sailed north along the Australian coast. She narrowly avoided disaster after running aground on the Great Barrier Reef and he then beached her on the mainland for seven weeks to permit rudimentary repairs to her hull. On 10 October 1770, she limped into port in Batavia in the Dutch East Indies for more substantial repairs, her crew sworn to secrecy about the lands they had visited. She resumed her journey on 26 December, rounded the Cape of Good Hope on 13 March 1771. Largely forgotten after her voyage, Endeavour spent the next three years sailing to and from the Falkland Islands. As of 2016 her wreck had not been located but was thought to be one of a cluster of five in Newport Harbor. Relics, including six of her cannon and an anchor, are displayed at maritime museums worldwide, a replica of Endeavour was launched in 1994 and is berthed alongside the Australian National Maritime Museum in Sydney Harbour. The US space shuttle Endeavour is named after the ship and she is depicted on the New Zealand fifty-cent coin and she was ship-rigged and sturdily built with a broad, flat bow, a square stern, and a long box-like body with a deep hold. A flat-bottomed design made her well-suited to sailing in waters and allowed her to be beached for loading and unloading of cargo. Her hull, internal floors, and futtocks were built from white oak, her keel and stern post from elm. Plans of the ship also show a double keelson to lock the keel, floors, some doubt exists about the height of her standing masts, as surviving diagrams of Endeavour depict the body of the vessel only, and not the mast plan. If correct, this would produce an oddly truncated mast a full 9 feet shorter than the standards of the day,1794 at the top of this page. The replica standing mizzen is built to this shorter measurement and stepped in the hold on the keelson, on 16 February 1768, the Royal Society petitioned King George III to finance a scientific expedition to the Pacific to study and observe the 1769 transit of Venus across the sun. The Royal Society suggested command be given to Scottish geographer Alexander Dalrymple, whose acceptance was conditional on a brevet commission as a captain in the Royal Navy. However, First Lord of the Admiralty Edward Hawke refused, going so far as to say he would cut off his right hand than give command of a navy vessel to someone not educated as a seaman

James Cook
–
Captain James Cook FRS RN was a British explorer, navigator, cartographer, and captain in the Royal Navy. Cook joined the British merchant navy as a teenager and joined the Royal Navy in 1755 and he saw action in the Seven Years War, and subsequently surveyed and mapped much of the entrance to the Saint Lawrence River during the siege of Quebec. This helped bring Cook to the attention of the Admiralty and Royal Society, in three voyages Cook sailed thousands of miles across largely uncharted areas of the globe. He mapped lands from New Zealand to Hawaii in the Pacific Ocean in greater detail, as he progressed on his voyages of discovery he surveyed and named features, and recorded islands and coastlines on European maps for the first time. He displayed a combination of seamanship, superior surveying and cartographic skills, physical courage, Cook was attacked and killed while attempting to kidnap the native chief of Hawaii during his third exploratory voyage in the Pacific in 1779. He left a legacy of scientific and geographical knowledge which was to influence his successors well into the 20th century, and numerous memorials worldwide have been dedicated to him. James Cook was born on 7 November 1728 in the village of Marton in Yorkshire and baptised on 14 November in the church of St Cuthbert. He was the second of eight children of James Cook, a Scottish farm labourer from Ednam in Roxburghshire, in 1736, his family moved to Airey Holme farm at Great Ayton, where his fathers employer, Thomas Skottowe, paid for him to attend the local school. In 1741, after five years schooling, he work for his father. For leisure, he would climb a hill, Roseberry Topping, enjoying the opportunity for solitude. Cooks Cottage, his parents last home, which he is likely to have visited, is now in Melbourne, having moved from England and reassembled, brick by brick. In 1745, when he was 16, Cook moved 20 miles to the village of Staithes. Historians have speculated that this is where Cook first felt the lure of the sea while gazing out of the shop window. After 18 months, not proving suitable for work, Cook travelled to the nearby port town of Whitby to be introduced to friends of Sandersons, John. The Walkers, who were Quakers, were prominent local ship-owners in the coal trade and their house is now the Captain Cook Memorial Museum. Cook was taken on as a merchant navy apprentice in their fleet of vessels. His first assignment was aboard the collier Freelove, and he spent several years on this and various other coasters, sailing between the Tyne and London. As part of his apprenticeship, Cook applied himself to the study of algebra, geometry, trigonometry, navigation and his three-year apprenticeship completed, Cook began working on trading ships in the Baltic Sea

Slavery
–
A slave is unable to withdraw unilaterally from such an arrangement and works without remuneration. Many scholars now use the chattel slavery to refer to this specific sense of legalised. In a broader sense, however, the word slavery may also refer to any situation in which an individual is de facto forced to work against his or her will. Scholars also use the generic terms such as unfree labour or forced labour. However – and especially under slavery in broader senses of the word – slaves may have some rights and/or protections, Slavery began to exist before written history, in many cultures. A person could become a slave from the time of their birth, capture, while slavery was institutionally recognized by most societies, it has now been outlawed in all recognized countries, the last being Mauritania in 2007. Nevertheless, there are still more slaves today than at any point in history. The most common form of the trade is now commonly referred to as human trafficking. Chattel slavery is still practiced by the Islamic State of Iraq. An older interpretation connected it to the Greek verb skyleúo to strip a slain enemy, there is a dispute among historians about whether terms such as unfree labourer or enslaved person, rather than slave, should be used when describing the victims of slavery. Chattel slavery, also called traditional slavery, is so named because people are treated as the chattel of the owner and are bought, although it dominated many societies in the past, this form of slavery has been formally abolished and is very rare today. Even when it can be said to survive, it is not upheld by the system of any internationally recognized government. Indenture, otherwise known as bonded labour or debt bondage is a form of labour under which a person pledges himself or herself against a loan. The services required to repay the debt, and their duration, debt bondage can be passed on from generation to generation, with children required to pay off their parents debt. It is the most widespread form of slavery today, debt bondage is most prevalent in South Asia. This may also include institutions not commonly classified as slavery, such as serfdom, conscription, Human trafficking primarily involves women and children forced into prostitution. And is the fastest growing form of forced labour, with Thailand, Cambodia, India, Brazil, in 2007, Human Rights Watch estimated that 200,000 to 300,000 children served as soldiers in current conflicts. A forced marriage may be regarded as a form of slavery by one or more of the involved in the marriage

Royal Society
–
Founded in November 1660, it was granted a royal charter by King Charles II as The Royal Society. The society is governed by its Council, which is chaired by the Societys President, according to a set of statutes and standing orders. The members of Council and the President are elected from and by its Fellows, the members of the society. As of 2016, there are about 1,600 fellows, allowed to use the postnominal title FRS, there are also royal fellows, honorary fellows and foreign members, the last of which are allowed to use the postnominal title ForMemRS. The Royal Society President is Venkatraman Ramakrishnan, who took up the post on 30 November 2015, since 1967, the society has been based at 6–9 Carlton House Terrace, a Grade I listed building in central London which was previously used by the Embassy of Germany, London. The Royal Society started from groups of physicians and natural philosophers, meeting at variety of locations and they were influenced by the new science, as promoted by Francis Bacon in his New Atlantis, from approximately 1645 onwards. A group known as The Philosophical Society of Oxford was run under a set of rules still retained by the Bodleian Library, after the English Restoration, there were regular meetings at Gresham College. It is widely held that these groups were the inspiration for the foundation of the Royal Society, I will not say, that Mr Oldenburg did rather inspire the French to follow the English, or, at least, did help them, and hinder us. But tis well known who were the men that began and promoted that design. This initial royal favour has continued and, since then, every monarch has been the patron of the society, the societys early meetings included experiments performed first by Hooke and then by Denis Papin, who was appointed in 1684. These experiments varied in their area, and were both important in some cases and trivial in others. The Society returned to Gresham in 1673, there had been an attempt in 1667 to establish a permanent college for the society. Michael Hunter argues that this was influenced by Solomons House in Bacons New Atlantis and, to a lesser extent, by J. V. The first proposal was given by John Evelyn to Robert Boyle in a letter dated 3 September 1659, he suggested a scheme, with apartments for members. The societys ideas were simpler and only included residences for a handful of staff and these plans were progressing by November 1667, but never came to anything, given the lack of contributions from members and the unrealised—perhaps unrealistic—aspirations of the society. During the 18th century, the gusto that had characterised the early years of the society faded, with a number of scientific greats compared to other periods. The pointed lightning conductor had been invented by Benjamin Franklin in 1749, during the same time period, it became customary to appoint society fellows to serve on government committees where science was concerned, something that still continues. The 18th century featured remedies to many of the early problems

William Bligh
–
Vice admiral William Bligh FRS RN was an officer of the British Royal Navy and a colonial administrator. Fifteen years after the Bounty mutiny, he was appointed Governor of New South Wales in Australia and his actions directed against the trade resulted in the so-called Rum Rebellion, during which Bligh was again placed under arrest and deposed from his command. William Bligh was born on 9 September 1754 but it is not clear where. It is likely that he was born in Plymouth, Devon, as he was baptised at St Andrews Church, Plymouth on 4 October 1754, Blighs ancestral home of Tinten Manor in St Tudy near Bodmin, Cornwall, is also a possibility. Blighs mother, Jane Pearce, was a widow who married Francis at the age of 40. Bligh was signed for the Royal Navy at age seven, at a time when it was common to sign on a young gentleman simply to gain, or at least record, the experience at sea required for a commission. In 1770, at age 16, he joined HMS Hunter as an able seaman and he became a midshipman early in the following year. In September 1771, Bligh was transferred to the Crescent and remained on the ship for three years, Bligh returned to England at the end of 1780 and was able to give details of Cooks last voyage. Bligh married Elizabeth Betham, daughter of a collector, on 4 February 1781. The wedding took place at nearby Onchan, a few days later, he was appointed to serve on HMS Belle Poule as master. Soon after this, in August 1781, he fought in the Battle of Dogger Bank under Admiral Parker, for the next 18 months, he was a lieutenant on various ships. He also fought with Lord Howe at Gibraltar in 1782, between 1783 and 1787, Bligh was a captain in the merchant service. Like many lieutenants, he would have found employment in the Navy, however. In 1787, Bligh was selected as commander of Bounty and he rose eventually to the rank of vice admiral in the Royal Navy. William Blighs naval career involved various appointments and assignments and he first rose to prominence as Master of Resolution, under the command of Captain Cook. Bligh received praise from Cook during what would be the final voyage. Bligh served on three of the ships from Fletcher Christians naval career. In the early 1780s, while in the merchant service, Bligh became acquainted with a man named Fletcher Christian
36.
HMS Bounty
–
HMS Bounty, also known as HM Armed Vessel Bounty, was a small merchant vessel purchased by the Royal Navy for a botanical mission. The ship was sent to the Pacific Ocean under the command of William Bligh to acquire breadfruit plants and that mission was never completed due to a mutiny led by Acting Lieutenant Fletcher Christian. This incident is now known as the Mutiny on the Bounty. The ship was burned on Pitcairn Island by the mutineers. The remains of the Bounty were re-discovered in 1957 by an American adventurer, Bounty was originally known as collier Bethia, built in 1784 at the Blaydes shipyard in Kingston upon Hull, East Yorkshire, England. The vessel was purchased by the Royal Navy for £1,950 on 23 May 1787, refit, the ship was relatively small at 215 tons, but had three masts and was full-rigged. After conversion for the expedition, she was equipped with four 4-pounder cannon. The experiment was proposed by Sir Joseph Banks, who recommended William Bligh as commander, in June 1787, Bounty was refitted at Deptford. The great cabin was converted to house the potted breadfruit plants, the ships complement was 46 men, a single commissioned officer,43 other Royal Navy personnel, and two civilian botanists. On 23 December 1787, Bounty sailed from Spithead for Tahiti, for a full month, the crew attempted to take the ship around Cape Horn, but adverse weather prevented this. Bligh then proceeded east, rounding the tip of Africa. During the outward voyage, Bligh demoted Sailing Master John Fryer and this act seriously damaged the relationship between Bligh and Fryer, and Fryer later claimed that Blighs act was entirely personal. Bligh is commonly portrayed as the epitome of abusive sailing captains, caroline Alexander points out in her 2003 book The Bounty that Bligh was relatively lenient compared with other British naval officers. Bligh enjoyed the patronage of Sir Joseph Banks, a wealthy botanist and that, together with his experience sailing with Cook, familiarity with navigation in the area, and local customs were probably important factors in his appointment. Bounty reached Tahiti on 26 October 1788, after ten months at sea, Bligh and his crew spent five months in Tahiti, then called Otaheite, collecting and preparing 1,015 breadfruit plants to be transported. Bligh allowed the crew to live ashore and care for the breadfruit plants. Many of the seamen and some of the gentlemen had themselves tattooed in native fashion. Masters Mate and Acting Lieutenant Fletcher Christian married Maimiti, a Tahitian woman, other of Bountys warrant officers and seamen were also said to have formed connections with native women

Seedless fruit
–
A seedless fruit is a fruit developed to possess no mature seeds. As consumption of fruits is generally easier and more convenient. Most commercially produced seedless fruits have been developed from plants whose fruits normally contain numerous relatively large hard seeds distributed throughout the flesh of the fruit, common varieties of seedless fruits include watermelons, tomatoes, grapes, and bananas. Additionally, there are numerous seedless citrus fruits, such as oranges, lemons, the term seedless fruit is biologically somewhat contradictory, since fruits are usually defined botanically as mature ovaries containing seeds. Seedless banana and watermelon fruits are produced on triploid plants, whose three sets of chromosomes make it unlikely for meiosis to produce fertile gametes. Such plants can arise by mutation or by hybridization between diploid and tetraploid individuals of the same or different species. Some species, such as tomato, pineapple, and cucumber, produce seedless fruit if not pollinated, but do produce seeded fruit if pollination occurs. Lacking seeds, and thus the capacity to propagate via the fruit, in such cases the resulting plants are genetically identical clones. By contrast, seedless watermelons are grown from seeds and these seeds are produced by crossing diploid and tetraploid lines of watermelon, with the resulting seeds producing sterile triploid plants. Fruit development is triggered by pollination, so plants must be grown alongside a diploid strain to provide pollen. Triploid plants with seedless fruits can also be produced using endosperm culture for the regeneration of triploid plantlets from endosperm tissue via somatic embryogenesis, one disadvantage of most seedless crops is a significant reduction in the amount of genetic diversity in the species. As genetically identical clones, a pest or disease that affects one individual is capable of affecting each of its clones

Saint Helena
–
It is part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha. Saint Helena measures about 16 by 8 kilometres and has a population of 4,534 and it was named after Saint Helena of Constantinople. The island, one of the most remote islands in the world, was uninhabited when discovered by the Portuguese in 1502 and it was an important stopover for ships sailing to Europe from Asia and South Africa for centuries. Napoleon was imprisoned there in exile by the British, as were Dinuzulu kaCetshwayo, between 1791 and 1833, Saint Helena became the site of a series of experiments in conservation, reforestation and attempts to boost rainfall artificially. This environmental intervention was closely linked to the conceptualisation of the processes of environmental change, Saint Helena is Britains second-oldest remaining overseas territory after Bermuda. The Portuguese found the island uninhabited, with an abundance of trees and they imported livestock, fruit trees and vegetables, and built a chapel and one or two houses. Englishman Sir Francis Drake probably located the island on the leg of his circumnavigation of the world. In developing their Far East trade, the Dutch also began to frequent the island, the Dutch Republic formally made claim to Saint Helena in 1633, although there is no evidence that they ever occupied, colonized, or fortified it. By 1651, the Dutch had mainly abandoned the island in favour of their colony at the Cape of Good Hope. In 1657, Oliver Cromwell granted the English East India Company a charter to govern Saint Helena and, the following year, the first governor Captain John Dutton arrived in 1659, making Saint Helena one of Britains oldest colonies outside North America and the Caribbean. A fort and houses were built, after the Restoration of the English monarchy in 1660, the East India Company received a royal charter giving it the sole right to fortify and colonise the island. The fort was renamed James Fort and the town Jamestown, in honour of the Duke of York, between January and May 1673, the Dutch East India Company forcibly took the island, before English reinforcements restored English East India Company control. The company experienced difficulty attracting new immigrants, and sentiments of unrest, a census in 1723 recorded 1,110 people, including 610 slaves. The island enjoyed a period of prosperity from about 1770. Captain James Cook visited the island in 1775 on the leg of his second circumnavigation of the world. St. James Church was erected in Jamestown in 1774, the site of this telescope is near Saint Mathews Church in Hutts Gate in the Longwood district. The 680-metre high hill there is named for him and is called Halleys Mount, throughout this period, Saint Helena was an important port of call of the East India Company. East Indiamen would stop there on the leg of their voyages to British India

Saint Vincent (Antilles)
–
Saint Vincent is a volcanic island in the Caribbean. It is the largest island of the country Saint Vincent and the Grenadines and it is located in the Caribbean Sea, between Saint Lucia and Grenada. It is composed of partially submerged volcanic mountains and its largest volcano and the countrys highest peak, La Soufrière, is active, having last erupted in 1979. The territory was disputed between France and the United Kingdom in the 18th century, before being ceded to the British in 1763 and it gained independence on October 27,1979. Approximately 100,000 people live on the island, the rest of the population is dispersed along the coastal strip, which includes the other five main towns of Layou, Barrouallie, Chateaubelair, Georgetown, and Calliaqua. The people of Saint Vincent and the Grenadines are called Vincentians, the population of the island in 2012 was about 100,000. The main religions are Anglican, Methodist, Roman Catholic, other Protestant denominations such as Seventh-day Adventist, adult literacy was 88. 1% in 2004. Infant mortality in 2006 was 17 per 1,000 live births and life expectancy for men stood at 69 years, the active workforce in 2006 was 57,695 and unemployment in 2004 was 12%. Before 1498, the island had been called Hairouna by the Caribs, columbus named the island Saint Vincent, since it is said to have been discovered on 22 January, the feast day of the patron saint of Lisbon and Valencia, Vincent of Saragossa. Columbus and the Spanish conquistadors largely ignored St. Vincent and the smaller Grenadine islands nearby, Carib Indians aggressively prevented European settlement on St. Vincent until the 18th century. African slaves, whether shipwrecked or escaped from St. Lucia or Grenada and seeking refuge in St. Vincent, intermarried with the Caribs, now those of mixed African-Carib ancestry are known as Garifuna. The first Europeans to occupy St. Vincent were the French, however, following a series of wars and peace treaties, these islands were eventually ceded to the British. The French settlers cultivated coffee, tobacco, indigo, corn, St. Vincent was ceded to Britain by the Treaty of Paris, after which friction between the British and the Caribs led to the First Carib War. On taking control of the island in 1763, the British laid the foundations of Fort Charlotte, the island was restored to French rule in 1779 and regained by the British under the Treaty of Versailles. Between 1795 and 1796, with French support from Martinique, the Black Caribs, led by their chief, Joseph Chatoyer, fought a series of battles against the British. Their uprising was put down, however, resulting in almost 5,000 Black Caribs being exiled to the tiny island of Baliceaux off the coast of Bequia. Conflict between the British and the black Caribs continued until 1796, when General Abercrombie crushed a revolt fomented by the French radical Victor Hugues, the British deported more than 5,000 black Caribs to Roatán, an island off the coast of Honduras. Fort Charlotte was completed by 1806, like the French before them, the British also used African slaves to work plantations of sugar, coffee, indigo, tobacco, cotton and cocoa until full emancipation in 1838

Jamaica
–
Jamaica is an island country situated in the Caribbean Sea, consisting of the third-largest island of the Greater Antilles. The island,10,990 square kilometres in area, lies about 145 kilometres south of Cuba, Jamaica is the fourth-largest island country in the Caribbean, by area. Inhabited by the indigenous Arawak and Taíno peoples, the island came under Spanish rule following the arrival of Christopher Columbus in 1494, Many of the indigenous people died of disease, and the Spanish imported African slaves as labourers. Named Santiago, the island remained a possession of Spain until 1655, under British colonial rule Jamaica became a leading sugar exporter, with its plantation economy highly dependent on slaves imported from Africa. The British fully emancipated all slaves in 1838, and many chose to have subsistence farms rather than to work on plantations. Beginning in the 1840s, the British imported Chinese and Indian indentured labour to work on plantations, the island achieved independence from the United Kingdom on 6 August 1962. With 2.8 million people, Jamaica is the third-most populous Anglophone country in the Americas, Kingston is the countrys capital and largest city, with a population of 937,700. Jamaicans predominately have African ancestry, with significant European, Chinese, Hakka, Indian, due to a high rate of emigration for work since the 1960s, Jamaica has a large diaspora around the world, particularly in Canada, the United Kingdom, and the United States. Jamaica is a Commonwealth realm, with Queen Elizabeth II as its monarch and her appointed representative in the country is the Governor-General of Jamaica, an office held by Sir Patrick Allen since 2009. Andrew Holness has served as the head of government and Prime Minister of Jamaica from March 2016, the indigenous people, the Taíno, called it Xaymaca in Arawakan, meaning the Land of Wood and Water or the Land of Springs. Colloquially Jamaicans refer to their island as the Rock. Slang names such as Jamrock, Jamdown, or briefly Ja, have derived from this, the Arawak and Taíno indigenous people, originating in South America, settled on the island between 4000 and 1000 BC. When Christopher Columbus arrived in 1494, there were more than 200 villages ruled by caciques, the south coast of Jamaica was the most populated, especially around the area now known as Old Harbour. The Taino still inhabited Jamaica when the English took control of the island in 1655, the Jamaican National Heritage Trust is attempting to locate and document any evidence of the Taino/Arawak. Christopher Columbus claimed Jamaica for Spain after landing there in 1494 and his probable landing point was Dry Harbour, now called Discovery Bay, although there is some debate that it might have been St. Anns Bay. St. Anns Bay was named Saint Gloria by Columbus, as the first sighting of the land, the capital was moved to Spanish Town, then called St. Jago de la Vega, around 1534. Spanish Town has the oldest cathedral of the British colonies in the Caribbean, the Spanish were forcibly evicted by the English at Ocho Rios in St. Ann. In 1655, the English, led by Sir William Penn and General Robert Venables, the English continued to import African slaves as labourers

Honolulu
–
Honolulu is the capital and largest city of the U. S. state of Hawaii. It is an part of and the county seat of the City and County of Honolulu on the island of Oahu. The city is the gateway to Hawaii and a major portal into the United States. The city is also a hub for international business, military defense, as well as famously being host to a diverse variety of east-west and Pacific culture, cuisine. Honolulu is the most remote city of its size in the world and is both the westernmost and the southernmost major U. S. city. For statistical purposes, the U. S. Census Bureau recognizes the area commonly referred to as City of Honolulu as a census county division. Honolulu is a financial center of the islands and of the Pacific Ocean. The population of the city of Honolulu was 337,256 as of the 2010 census, while the Honolulu CCD was 390,738, Honolulu means sheltered harbor or calm port. The old name is said to be Kou, a district encompassing the area from Nuuanu Avenue to Alakea Street. The city has been the capital of the Hawaiian Islands since 1845, as of 2015, Honolulu was ranked high on world livability rankings, and was also ranked as the 2nd safest city in the U. S. It is also the most populated Oceanian city outside Australasia and ranks second to Auckland as the most populous city in Polynesia, evidence of the first settlement of Honolulu by the original Polynesian migrants to the archipelago comes from oral histories and artifacts. These indicate that there was a settlement where Honolulu now stands in the 11th century, however, after Kamehameha I conquered Oʻahu in the Battle of Nuʻuanu at Nuʻuanu Pali, he moved his royal court from the Island of Hawaiʻi to Waikīkī in 1804. His court relocated in 1809 to what is now downtown Honolulu, the capital was moved back to Kailua-Kona in 1812. In 1794, Captain William Brown of Great Britain was the first foreigner to sail into what is now Honolulu Harbor, more foreign ships followed, making the port of Honolulu a focal point for merchant ships traveling between North America and Asia. In 1845, Kamehameha III moved the permanent capital of the Hawaiian Kingdom from Lahaina on Maui to Honolulu and he and the kings that followed him transformed Honolulu into a modern capital, erecting buildings such as St. Andrews Cathedral, ʻIolani Palace, and Aliʻiōlani Hale. At the same time, Honolulu became the center of commerce in the islands, an economic and tourism boom following statehood brought rapid economic growth to Honolulu and Hawaiʻi. Modern air travel brings, as of 2007,7.6 million visitors annually to the islands, today, Honolulu is a modern city with numerous high-rise buildings, and Waikīkī is the center of the tourism industry in Hawaiʻi, with thousands of hotel rooms. According to the United States Census Bureau, the CDP has an area of 68.4 square miles

Leaf
–
A leaf is an organ of a vascular plant and is the principal lateral appendage of the stem. The leaves and stem together form the shoot, Leaves are collectively referred to as foliage, as in autumn foliage. Although leaves can be seen in different shapes, sizes and textures, typically a leaf is a thin, dorsiventrally flattened organ, borne above ground. Most leaves have distinctive upper surface and lower surface that differ in colour, hairiness, broad, flat leaves with complex venation are known as megaphylls and the species that bear them, the majority, as broad-leaved or megaphyllous plants. In others, such as the clubmosses, with different evolutionary origins, some leaves, such as bulb scales are not above ground, and in many aquatic species the leaves are submerged in water. Succulent plants often have thick juicy leaves, but some leaves are without major photosynthetic function and may be dead at maturity, as in some cataphylls, furthermore, several kinds of leaf-like structures found in vascular plants are not totally homologous with them. Examples include flattened plant stems called phylloclades and cladodes, and flattened leaf stems called phyllodes which differ from both in their structure and origin. Many structures of plants, such as the phyllids of mosses and liverworts and even of some foliose lichens. Leaves are the most important organs of most vascular plants and these are then further processed by chemical synthesis into more complex organic molecules such as cellulose, the basic structural material in plant cell walls. The plant must therefore bring these three together in the leaf for photosynthesis to take place. Once sugar has been synthesized, it needs to be transported to areas of growth such as the plant shoots and roots. Vascular plants transport sucrose in a tissue called the phloem. The phloem and xylem are parallel to each other but the transport of materials is usually in opposite directions. Within the leaf these vascular systems branch to form veins which supply as much as the leaf as possible and they are arranged on the plant so as to expose their surfaces to light as efficiently as possible without shading each other, but there are many exceptions and complications. For instance plants adapted to windy conditions may have pendent leaves, such as in many willows, the flat, or laminar, shape also maximises thermal contact with the surrounding air, promoting cooling. Functionally, in addition to photosynthesis the leaf is the site of transpiration and guttation. Many gymnosperms have thin needle-like or scale-like leaves that can be advantageous in cold climates with frequent snow and these are interpreted as reduced from megaphyllous leaves of their Devonian ancestors. For xerophytes the major constraint is not light flux or intensity, some window plants such as Fenestraria species and some Haworthia species such as Haworthia tesselata and Haworthia truncata are examples of xerophytes. and Bulbine mesembryanthemoides

Pinnation
–
Pinnation is the arrangement of feather-like or multi-divided features arising from both sides of a common axis. Pinnation occurs in biological morphology, in crystals, such as forms of ice or metal crystals. The term derives from the Latin word pinna meaning feather, wing, a similar concept is pectination, which is a comb-like arrangement of parts. Pinnation is commonly referred to in contrast to palmation, in which the parts or structures radiate out from a common point. The terms pinnation and pennation are cognate, and although they are used distinctly. Botanically, pinnation is an arrangement of structures arising at multiple points along a common axis. For example, once-divided leaf blades having leaflets arranged on both sides of a rachis are pinnately compound leaves, many palms and most cycads and grevilleas have pinnately divided leaves. Most species of ferns have pinnate or more highly divided fronds, plants with pinnate leaves are sometimes colloquially called feather-leaved. Pinnatisect, cut all the way to the midrib or other axis, pinnate-pinnatifid, pinnate, with the pinnae being pinnatifid. Paripinnate, pinnately compound leaves in which leaflets are born in pairs along the rachis without a terminal leaflet. Imparipinnate, pinnately compound leaves in which there is a terminal leaflet rather than a terminal pair of leaflets. Bipinnate, pinnately compound leaves in which the leaflets are themselves pinnately compound, tripinnate, pinnately compound leaves in which the leaflets are themselves bipinnate, also called thrice-pinnate. Tetrapinnate, pinnately compound leaves in which the leaflets are themselves tripinnate, unipinnate, solitary compound leaf with a row of leaflets arranged along each side of a common rachis. The term pinnula is the Latin diminutive of pinna, either as such or in the Anglicised form, pinnule, some apply it to the leaflets of a pinna, especially the leaflets of bipinnate or tripinnate leaves. Others also or alternatively apply it second or third divisions of a bipinnate or tripinnate leaf. It is the ultimate division of a compound leaf, or a pinnate subdivision of a multipinnate leaf. Pinnation occurs in certain systems in which all major tributary streams enter the main channels by flowing in one direction at an oblique angle

Caulking
–
Caulking is both the processes and material to seal joints or seams in various structures and some types of piping. The oldest form of caulking is used to make the seams in wooden boats or ships watertight, a related process was formerly employed to join sections of cast iron sewerage pipe. Caulking is also the term to describe the used to make riveted iron or steel ships. The same term also refers to the application of flexible sealing compounds to close up gaps in buildings and other structures against water, air, dust, insects, or as a component in firestopping. In the tunnelling industry, caulking refers to the sealing of joints in segmental precast concrete tunnels, traditional caulking on wooden vessels uses fibers of cotton and oakum. These fibers are driven into the seam between planks, with a caulking mallet and a broad chisel-like tool called a caulking iron. In riveted steel or iron ship construction, caulking was a process of rendering seams watertight by driving a thick and this had the effect of displacing the metal into a close fit with the adjoining piece. Originally done by hand much like wooden vessel caulking, pneumatic tools were later employed, with the advent of electric-arc welding for ship construction, steel ship caulking was rendered obsolete. Caulking of iron and steel, of the type described above for ships hulls, was also used by boilermakers in the era of riveted boilers to make the joints watertight and steamtight. Caulk can refer either to the substance or to the process of applying it. Caulking as a term has spread to the trade, meaning the activity of closing up joints. The function of caulking is to provide insulation, control water penetration. This is mostly done with ready-mixed construction chemicals sold as such as silicone, polyurethane, polysulfide, sylil-terminated-polyether or polyurethane. Unlike construction caulk, which is applied where no building movement is expected, one-component sealants are commonly sold in cartridges which are loaded into a pistol-like caulking gun or barrel gun for application. During the tool-working time, which varies by chemistry, the bead can be pressed into the joint so that it can bond with the materials on both sides, and also be smoothed. The time it takes for a chemical sealant to become a rubber is known as the time and varies by temperature. Silicone sealants form a durable, water-tight seal, but are not typically paintable, some silicone sealants are made to be paintable with certain types of paint such as water or oil-based paints. Backer rods can also be used to reduce consumption of the caulking by filling part of the joints, backer rod is often round and rope-like in shape but many special types and shaped such as square, rectangular and D-shapes are available

Plant reproductive morphology
–
Plant reproductive morphology is the study of the physical form and structure of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers, which are the structures of angiosperms, are the most varied physically. Plants that are not flowering plants also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction, christian Konrad Sprengel studied the reproduction of flowering plants and for the first time it was understood that the pollination process involved both biotic and abiotic interactions. Charles Darwins theories of natural selection utilized this work to build his theory of evolution, Plants have complex lifecycles involving alternation of generations. One generation, the sporophyte, gives rise to the next generation asexually via spores, spores may be identical isospores or come in different sizes, but strictly speaking, spores and sporophytes are neither male nor female because they do not produce gametes. The alternate generation, the gametophyte, produces gametes, eggs and/or sperm, a gametophyte can be be monoicous, producing both eggs and sperm or dioicous, either female or male. In the bryophytes, the gametophyte is the dominant generation. In ferns and seed plants the sporophyte is the dominant generation, the obvious visible plant, whether a small herb or a large tree, is the sporophyte, and the gametophyte is very small. In seed plants, each female gametophyte, and the spore that gives rise to it, is hidden within the sporophyte and is dependent on it for nutrition. Each male gametophyte consists of from two to four cells enclosed within the protective wall of a pollen grain. The sporophyte of a plant is often described using sexual terms based on the sexuality of the gametophyte it gives rise to. For example, a sporophyte that produces spores that give rise only to male gametophytes may be described as male, even though the sporophyte itself is asexual, producing only spores. Similarly, flowers produced by the sporophyte may be described as unisexual or bisexual, the flower is the characteristic structure concerned with sexual reproduction in flowering plants. Flowers vary enormously in their construction, a complete flower, like that of Ranunculus glaberrimus shown in the figure, has a calyx of outer sepals and a corolla of inner petals. The sepals and petals form the perianth. Next inwards there are numerous stamens, which produce pollen grains, stamens may be called the male parts of a flower and collectively form the androecium. Finally in the middle there are carpels, which at maturity one or more ovules. Carpels may be called the parts of a flower and collectively form the gynoecium

Flower
–
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in plants that are floral. The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs, Flowers may facilitate outcrossing or allow selfing. Some flowers produce diaspores without fertilization, Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds, the essential parts of a flower can be considered in two parts, the vegetative part, consisting of petals and associated structures in the perianth, and the reproductive or sexual parts. A stereotypical flower consists of four kinds of structures attached to the tip of a short stalk, each of these kinds of parts is arranged in a whorl on the receptacle. The four main whorls are as follows, Collectively the calyx, corolla, the next whorl toward the apex, composed of units called petals, which are typically thin, soft and colored to attract animals that help the process of pollination. Androecium, the whorl, consisting of units called stamens. Stamens consist of two parts, a called a filament, topped by an anther where pollen is produced by meiosis. Gynoecium, the innermost whorl of a flower, consisting of one or more units called carpels, the carpel or multiple fused carpels form a hollow structure called an ovary, which produces ovules internally. Ovules are megasporangia and they in turn produce megaspores by meiosis which develop into female gametophytes and these give rise to egg cells. The gynoecium of a flower is described using an alternative terminology wherein the structure one sees in the innermost whorl is called a pistil. A pistil may consist of a carpel or a number of carpels fused together. The sticky tip of the pistil, the stigma, is the receptor of pollen, the supportive stalk, the style, becomes the pathway for pollen tubes to grow from pollen grains adhering to the stigma. The relationship to the gynoecium on the receptacle is described as hypogynous, perigynous, although the arrangement described above is considered typical, plant species show a wide variation in floral structure. These modifications have significance in the evolution of flowering plants and are used extensively by botanists to establish relationships among plant species, the four main parts of a flower are generally defined by their positions on the receptacle and not by their function. Many flowers lack some parts or parts may be modified into other functions and/or look like what is typically another part, in some families, like Ranunculaceae, the petals are greatly reduced and in many species the sepals are colorful and petal-like. Other flowers have modified stamens that are petal-like, the flowers of Peonies and Roses are mostly petaloid stamens
