Fuchsia (color)
–
Fuchsia is a vivid purplish red color, named after the color of the flower of the fuchsia plant, which took its name from the 16th century German botanist Leonhart Fuchs. The color fuchsia was first introduced as the color of a new aniline dye called fuchsine, patented in 1859 by the French chemist François-Emmanuel Verguin. The dye was renamed later in the same year, to celebrate a victory of the French army at the Battle of Magenta on June 4,1859. In color printing and design, there are variations between magenta and fuchsia. Fuchsia is usually a more color, whereas magenta is more reddish. Fuchsia flowers themselves contain a variety of purples. The first recorded use of fuchsia as a name in English was in 1892. The first synthetic dye the color of fuchsia, called fuchsine, was patented in 1859 by François-Emmanuel Verguin and it was later renamed magenta, and became highly popular under that name. The name fuchsia is used on the HTML web color list for this color and they are both composed the same way, by combining an equal amount of blue and red light at full brightness, as shown in the image on the left. Displayed at right is the pale tint of fuchsia. The first recorded use of fuchsia as a color name in English was in 2014. At right is displayed the color French fuchsia, which is the tone of fuchsia called fuchsia in a color list popular in France, fashion fuchsia is a color used in fashion when a slightly less saturated color than shocking pink is desired. It also goes by the name Hollywood cerise, Fuchsia rose is the color that was chosen as the 2001 Pantone color of the year by Pantone. The source of color is the Pantone Textile Paper eXtended color list. Although red-purple is a seldom used color name in English, in Spanish it is regarded one of the tones of purple. The color fuchsia purple is displayed at right, the source of this color is the Pantone Textile Paper eXtended color list, color #18-2436 TPX—Fuchsia Purple. Deep fuchsia is the color that is called fuchsia in the List of Crayola crayon colors, displayed at right is the color fandango. The first recorded use of fandango as a name in English was in 1925

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

Angiosperms
–
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

Myrtales
–
The Myrtales are an order of flowering plants placed as a sister to the eurosids II clade as of the publishing of the Eucalyptus grandis genome in June 2014. The APG III system of classification for angiosperms still places it within the eurosids, the following families are included as of APG III, Alzateaceae S. A. Graham Combretaceae R. Br. The Cronquist system gives essentially the composition, except the Vochysiaceae are removed to the order Polygalales. The families Sonneratiaceae, Trapaceae, and Punicaceae are removed from the Lythraceae, in the classification system of Dahlgren the Myrtales were in the superorder Myrtiflorae. The APG III system agrees with the older Cronquist circumscriptions of treating Psiloxylaceae and Heteropyxidaceae within Myrtaceae, ellagitannins are reported in dicotyledoneous angiospermes, and notably in species in the order Myrtales. Myrtales is dated to have begun 89-99 million years ago in Australasia, there is some contention as to that date however, which was obtained using nuclear DNA. When looking at chloroplast DNA, the ancestor is instead considered to have evolved in the mid-cretaceous period in Southeast Africa. Although the APG system classifies myrtales as within the eurosids, the published genome of Eucalyptus grandis places the order myrtales as a sister to the eurosids rather than inside them. The discrepancy is thought to have due to the difference between using a large number of taxa versus using a large number of genes for constructing a phylogeny. Conti, E. Erikkson, T.

Onagraceae
–
The Onagraceae are a family, known as the willowherb family or evening primrose family, of flowering plants. They include about 650 species of herbs, shrubs, and trees in 17 genera, the family is widespread, occurring on every continent from boreal to tropical regions. The family includes a number of garden plants, including evening primroses. Some, particularly the willowherbs are common weeds in gardens and in the wild, the family is characterised by flowers with usually four sepals and petals, in some genera, such as Fuchsia, the sepals are as brightly coloured as the petals. The seeds are very small. In some genera, such as Epilobium, they have tufts of hairs and are dispersed on the wind, in others, such as Fuchsia, the seeds develop in juicy berries dispersed by animals. The leaves are commonly opposite or whorled, but are arranged in some species, in most, they are simple. The pollen grains in many genera are loosely held together by viscin threads, the family is named after the genus Onagra in 1836 by John Lindley in the second edition of A Natural System of Botany.

Carl Linnaeus
–
Carl Linnaeus, also known after his ennoblement as Carl von Linné, was a Swedish botanist, physician, and zoologist, who formalised the modern system of naming organisms called binomial nomenclature. He is known by the father of modern taxonomy. Many of his writings were in Latin, and his name is rendered in Latin as Carolus Linnæus, Linnaeus was born in the countryside of Småland, in southern Sweden. He received most of his education at Uppsala University. He lived abroad between 1735 and 1738, where he studied and also published a first edition of his Systema Naturae in the Netherlands and he then returned to Sweden, where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on journeys through Sweden to find and classify plants. In the 1750s and 1760s, he continued to collect and classify animals, plants, and minerals, at the time of his death, he was one of the most acclaimed scientists in Europe. The philosopher Jean-Jacques Rousseau sent him the message, Tell him I know no man on earth. The German writer Johann Wolfgang von Goethe wrote, With the exception of Shakespeare and Spinoza, Swedish author August Strindberg wrote, Linnaeus was in reality a poet who happened to become a naturalist. Among other compliments, Linnaeus has been called Princeps botanicorum, The Pliny of the North and he is also considered as one of the founders of modern ecology. In botany, the abbreviation used to indicate Linnaeus as the authority for species names is L. In older publications, sometimes the abbreviation Linn. is found, Linnæus was born in the village of Råshult in Småland, Sweden, on 23 May 1707. He was the first child of Nicolaus Ingemarsson and Christina Brodersonia and his siblings were Anna Maria Linnæa, Sofia Juliana Linnæa, Samuel Linnæus, and Emerentia Linnæa. One of a line of peasants and priests, Nils was an amateur botanist, a Lutheran minister. Christina was the daughter of the rector of Stenbrohult, Samuel Brodersonius, a year after Linnæus birth, his grandfather Samuel Brodersonius died, and his father Nils became the rector of Stenbrohult. The family moved into the rectory from the curates house, even in his early years, Linnæus seemed to have a liking for plants, flowers in particular. Whenever he was upset, he was given a flower, which calmed him. Nils spent much time in his garden and often showed flowers to Linnaeus, soon Linnæus was given his own patch of earth where he could grow plants

Genus
–
A genus is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of classification, genus comes above species. In binomial nomenclature, the name forms the first part of the binomial species name for each species within the genus. Felis catus and Felis silvestris are two species within the genus Felis, Felis is a genus within the family Felidae. The composition of a genus is determined by a taxonomist, the standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. Moreover, genera should be composed of units of the same kind as other genera. The term comes from the Latin genus, a noun form cognate with gignere, linnaeus popularized its use in his 1753 Species Plantarum, but the French botanist Joseph Pitton de Tournefort is considered the founder of the modern concept of genera. The scientific name of a genus may be called the name or generic epithet. It plays a role in binomial nomenclature, the system of naming organisms. The rules for the names of organisms are laid down in the Nomenclature Codes. The standard way of scientifically describing species and other lower-ranked taxa is by binomial nomenclature, the generic name forms its first half. For example, the gray wolfs binomial name is Canis lupus, with Canis being the name shared by the wolfs close relatives. The specific name is written in lower-case and may be followed by names in zoology or a variety of infraspecific names in botany. Especially with these names, when the generic name is known from context. Because animals are typically only grouped within subspecies, it is written as a trinomen with a third name. Dog breeds, meanwhile, are not scientifically distinguished, there are several divisions of plant species and therefore their infraspecific names generally include contractions explaining the relation. For example, the genus Hibiscus includes hundreds of other species apart from the Rose of Sharon or common garden hibiscus, Rose of Sharon doesnt have subspecies but has cultivars that carry desired traits, such as the bright white H. syriaca Diana. Hawaiian hibiscus, meanwhile, includes several separate species, since not all botanists agree on the divisions or names between species, it is common to specify the source of the name using author abbreviations

Fuchsia triphylla
–
Fuchsia triphylla is one of over 110 species that comprise the genus Fuchsia. Due to its attractiveness and its blooming period which spans from early spring to late autumn. This has a resulted in a breed of cultivars allowing it to grow in various settings around the world. The visually appealing flowers of the Fuchsia triphylla have contributed to some of the most elegant Fuchsia hybrids produced today, Fuchsia triphylla are small shrub plants. They can grow as high as two or three feet, the leaves are simple, elliptical, and quite large. The petiole insertion is whorled and characterized with a red or maroon tint on the underside of the leaves, the flowers of Fuchsia triphylla are long and tubular. Flowers are generally a red-orange or red-purple color and they tend to droop over and have stamens that extend from the tip. As far as reproduction, this produces a large amount of both flowers and seeds. Fuchsia triphylla use their appealing nature to their advantage in their life cycle, the beautiful flowers they produce attract many different organisms, particularly hummingbirds, which come and transport pollen between flowers for germination. As a member of the genus Fuchsia, Fuchsia triphylla is a member of the family Onagraceae, because there is such a large number of species for this genus, the botanist Philip A. Munz broke the genus down into nine sections. As the first species described in the genus, Fuchsia triphylla is in Section Fuchsia, because Fuchsia triphylla is popular worldwide, it has also developed several common names. Some of these names include Honeysuckle Fuchsia, Firecracker Fuchsia and Fuchsia Thalia, charles Plumier is accredited with both the discovery and naming of Fuchsia. In the early 18th century, Plumier made an expedition to the Americas in search of a new genus, Fuchsia triphylla is the species that Plumier initially came upon and returned to France with. First, he named the genus Fuchsia after Leonhart Fuchs, Leonhart Fuchs was a popular German Medical Doctor who spent an immense amount of time studying plants with ambitions of discovering herbal remedies. Fucshia made its first official appearance in Nova Plantarum Americanum, Fuchsia triphylla was one of the first species named due to its early discovery, although new species have been continually discovered over the past several centuries. Plumier’s first encounter occurred on the hills of the Caribbean Islands, Fuchsia triphylla is native to Haiti and the Dominican Republic. Fuchsia triphylla is a species for cultivation, primarily for ornamental purposes. Although the plant is capable of living in a decent range of environments, ideal temperatures are just below 80 °F during the day and just over 60 °F at night

Hispaniola
–
Hispaniola is the 22nd-largest island in the world, located in the Caribbean island group, the Greater Antilles. It is the second largest island in the Caribbean after Cuba, two sovereign nations share the 76, 192-square-kilometre island. The only other shared island in the Caribbean is Saint Martin, Hispaniola is the site of the first permanent European settlement in the Americas, founded by Christopher Columbus on his voyages in 1492 and 1493. The island was called by various names by its native people, fernández de Oviedo and de las Casas both recorded that the island was called Haiti by the Taíno. DAnghiera added another name, Quizqueia, but later shows that the word does not seem to derive from the original Arawak Taíno language. When Columbus took possession of the island in 1492, he named it Insula Hispana, meaning the Spanish Island in Latin and La Isla Española, meaning the Spanish Island, in Spanish. De las Casas shortened the name to Española, and when d‘Anghiera detailed his account of the island in Latin, he rendered its name as Hispaniola. Due to Taíno, Spanish and French influences on the island, historically the whole island was referred to as Haiti, Hayti, Santo Domingo, St. Domingue. The name Haïti was adopted by Haitian revolutionary Jean-Jacques Dessalines in 1804, as the name of independent Saint-Domingue. It was also adopted as the name of independent Santo Domingo, as the Republic of Spanish Haiti. Christopher Columbus inadvertently landed on the island during his first voyage across the Atlantic in 1492, where his flagship, a contingent of men were left at an outpost christened La Navidad, on the north coast of present-day Haiti. The island was inhabited by the Taíno, one of the indigenous Arawak peoples, the Taino were at first tolerant of Columbus and his crew, and helped him to construct La Navidad on what is now Môle-Saint-Nicolas, Haiti, in December 1492. European colonization of the began in earnest the following year. In 1496 the town of Nueva Isabela was founded, after being destroyed by a hurricane, it was rebuilt on the opposite side of the Ozama River and called Santo Domingo. It is the oldest permanent European settlement in the Americas, several 16th century writers estimated the 1492 population of Hispaniola at over 1 million people. Twentieth-century estimates of the range from 60,000 to 8,000,000. Harsh enslavement by Spanish colonists, redirection of food supplies and labor towards the colonists, had a impact on both mortality and fertility over the first quarter century. Colonial administrators and Dominican and Hyeronimite priests observed that the search for gold, demographic data from two provinces in 1514 shows a low birth rate consistent with a 3. 5% annual population decline

Haiti

Haiti, officially the Republic of Haiti and formerly called Hayti, is a country located on the island of Hispaniola in the Greater Antilles archipelago of the Caribbean Sea. It occupies the western three-eighths of the island, which it shares with the Dominican Republic, the region was originally inhabited by the indigenous Taíno people. Spain discovered the island on 5 December 1492 during the first voyage of Christopher Columbus across the Atlantic, when Columbus initially landed in Haiti, he had thought he had found India or Asia. On Christmas Day 1492, Columbus flagship the Santa Maria ran aground north of what is now Limonade, the island was named La Española and claimed by Spain, which ruled until the early 17th century. Competing claims and settlements by the French led to the portion of the island being ceded to France. The development of plantations, worked by slaves brought from Africa. Upon his death in a prison in France, he was succeeded by his lieutenant, Jean-Jacques Dessalines, the Haitian Revolution lasted just over a dozen years, and apart from Alexandre Pétion, the first President of the Republic, all the first leaders of government were former slaves. The Citadelle Laferrière is the largest fortress in the Americas, Henri Christophe – former slave and first king of Haiti, Henri I – built it to withstand a possible foreign attack. It has the lowest Human Development Index in the Americas, most recently, in February 2004, a coup détat originating in the north of the country forced the resignation and exile of President Jean-Bertrand Aristide. A provisional government took control with security provided by the United Nations Stabilization Mission in Haiti, the name Haïti comes from the indigenous Taíno language which was the native name given to the entire island of Hispaniola to mean, land of high mountains. The h is silent in French and the ï in Haïti, is a mark used to show that the second vowel is pronounced separately. In English, this rule for the pronunciation is often disregarded, the name Haïti was restored by Haitian revolutionary Jean-Jacques Dessalines as the official name of independent Saint-Domingue, as a tribute to the Amerindian predecessors. The Taíno name for the island was Haiti. The people had migrated over centuries into the Caribbean islands from South America, genetic studies show they were related to the Yanomami of the Amazon Basin. They also originated in Central and South America, after migrating to Caribbean islands, in the 15th century, the Taíno were pushed into the northeast Caribbean islands by the Caribs. In the Taíno societies of the Caribbean islands, the largest unit of organization was led by a cacique, or chief. The caciquedoms were tributary kingdoms, with payment consisting of harvests, Taíno cultural artifacts include cave paintings in several locations in the country. These have become symbols of Haiti and tourist attractions

Dominican Republic

The Dominican Republic is a sovereign state occupying the eastern two-thirds of the island of Hispaniola, in the Greater Antilles archipelago in the Caribbean region. The western one-third of the island is occupied by the nation of Haiti, christopher Columbus landed on the Western part of Hispaniola, in what is now Haiti, on December 6,1492. The island became the first seat of the Spanish colonial rule in the New World, the Dominican people declared independence in November 1821 but were forcefully annexed by their more powerful neighbor Haiti in February 1822. After the 1844 victory in the Dominican War of Independence against Haitian rule the country again under Spanish colonial rule until the Dominican War of Restoration of 1865. The Dominican Republic experienced mostly internal strife until 1916, a civil war in 1965, the countrys last, was ended by another U. S. military occupation and was followed by the authoritarian rule of Joaquín Balaguer, 1966–1978. Since then, the Dominican Republic has moved toward representative democracy and has been led by Leonel Fernández for most of the time since 1996. Danilo Medina, the Dominican Republics current president, succeeded Fernandez in 2012, the Dominican Republic has the ninth-largest economy in Latin America and is the largest economy in the Caribbean and Central American region. Though long known for agriculture and mining, the economy is now dominated by services. Over the last two decades, the Dominican Republic have been standing out as one of the economies in the Americas – with an average real GDP growth rate of 5. 4% between 1992 and 2014. GDP growth in 2014 and 2015 reached 7.3 and 7. 0%, respectively, in the first half of 2016 the Dominican economy grew 7. 4% continuing its trend of rapid economic growth. Recent growth has been driven by construction, manufacturing and tourism, private consumption has been strong, as a result of low inflation, job creation, as well as high level of remittances. The Dominican Republic has a market, Bolsa de Valores de la Republica Dominicana. and advanced telecommunication system. Nevertheless, unemployment, government corruption, and inconsistent electric service remain major Dominican problems, the country also has marked income inequality. International migration affects the Dominican Republic greatly, as it receives, mass illegal Haitian immigration and the integration of Dominicans of Haitian descent are major issues. A large Dominican diaspora exists, mostly in the United States, contributes to development, the Dominican Republic is the most visited destination in the Caribbean. The year-round golf courses are major attractions, the island has an average temperature of 26 °C and great climatic and biological diversity. The country is also the site of the first cathedral, castle, monastery, and fortress built in all of the Americas, located in Santo Domingos Colonial Zone, a World Heritage Site. Music and sport are of importance in the Dominican culture, with Merengue and Bachata as the national dance and music

Minim (religious order)
–
The Minims are members of a Roman Catholic religious order of friars founded by Saint Francis of Paola in fifteenth-century Italy. The Order soon spread to France, Germany and Spain, at present there are only two fraternities of the Minim tertiaries, both are in Italy. The founder of the Order, Saint Francis of Paola, was born in 1416 and named in honor of St. Francis of Assisi. The boy became ill when he was one month old. Her prayer was granted, and at 13 years of age Francis fulfilled that votive year, after this year he dedicated himself to a life of solitude and penance as a hermit. In 1435, two followers joined Francis and began the community, which was first called the Poor Hermits of St. Francis of Assisi, Francis and his followers founded hermitages at Paterno in 1444 and Milazzo, Sicily, in 1469. At that time, the Pope also changed their status from that of hermits to mendicant friars, the name Minims comes from the Italian word minimo, meaning the smallest or the least, and their founder would call himself il minimo dei minimi. Francis of Paola wanted to distinguish himself as being of less significance than the Friars Minor founded by his patron saint. Francis composed a rule for the community in 1493, which was approved under the name of Hermits of the Order of the Minims. The definitive version of the rule was approved by Pope Julius II in the Bull Inter ceteros, July 28,1506. This vow is for perpetual abstinence from all meat and dairy products, veganism, except in case of grave illness, because of asceticism, The Order is also discalced in character and there are other acts of humility. Due to the somberness and morosity of the Lenten way of life, the Minim habit consists of a black tunic, with broad sleeves, a hood. It has a thick, black cord with a tassel to gird the robe, the Order of the Minims spread throughout Italy in the fifteenth century and was introduced to France in 1482, and later to Spain and to Germany in 1497. The houses in Spain, Germany, and France were suppressed during the following the French Revolution. By the turn of the 20th century, only 19 friaries remained, all, on 31 December 2010, the Order had 46 communities with 174 members,112 of them priests. The Munich friary of the German Minims brewed beer as means of support, but after the friars were expelled and it continues to brew the Paulaner brand of beer, which draws its name from Francis of Paola. Francis was called to France in 1483 by King Louis XI to serve as his deathbed confessor, while he was there, the Spanish ambassador, Don Pedro de Lucena, who was a very pious man, grew to know and admire him. He sent reports of the friar to his family back in Jaén

Charles Plumier was a French botanist, after whom the Frangipani genus Plumeria is named. Plumier is considered one of the most important of the explorers of his time. He made three botanizing expeditions to the West Indies, which resulted in a massive work Nova Plantarum Americanarum Genera and was appointed botanist to king Louis XIV of France, born in Marseille, at the age of sixteen he entered the religious order of the Minims. He devoted himself to the study of mathematics and physics, made physical instruments, and was an excellent draughtsman, painter, and turner. On being sent to the French monastery of Trinità dei Monti at Rome, after his return to France, he became a pupil of Joseph Pitton de Tournefort, whom he accompanied on botanical expeditions. He also explored the coasts of Provence and Languedoc and his work began in 1689, when, by order of the government, he accompanied the collector Joseph Donat Surian to the French Antilles, as Surians illustrator and writer. They remained a year and a half, as this first journey, written up by Plumier as Description des Plantes dAmérique, proved very successful, Plumier was appointed royal botanist. In 1693, by command of Louis XIV of France, he made his second journey, while in the West Indies, he was assisted by the Dominican botanist Jean-Baptiste Labat. Plumier also wrote treatises for the Journal des Savants and for the Mémoires de Trévoux, through his observations in Martinique, Plumier proved that the cochineal belongs to the animal kingdom and should be classed among the insects. All natural scientists of the 18th century spoke of him with admiration, Tournefort and Linnaeus named in his honour the genus Plumeria, which belongs to the family Apocynaceae and is indigenous in about forty species to Central America. Plumier identified and described Fuchsia, which he discovered on the island of Hispaniola in the Caribbean in 1696-7 and he published his first description of Fuchsia in 1703. The French explorer and botanist Louis Feuillée was one of his pupils and his first work was Description des plantes de lAmérique, it contained 108 plates, half of which represented ferns. This was followed by Nova plantarum americanarum genera, with 40 plates, in this work about one hundred genera, at a later date, Linnaeus adopted in his system, almost without change, these and other newly described genera arranged by Plumier. Plumier left a work in French and Latin ready to be printed entitled Traité des fougères de lAmérique, the publication Filicetum Americanum, with 222 plates, was compiled from those already mentioned. Plumier also wrote another book of a different character on turning, LArt de tourner. The manuscript of the translation is at St. Petersburg, Description des plantes de lAmérique on Botanicus

Botany, also called plant science, plant biology or phytology, is the science of plant life and a branch of biology. A botanist or plant scientist is a scientist who specialises in this field, the term botany comes from the Ancient Greek word βοτάνη meaning pasture, grass, or fodder, βοτάνη is in turn derived from βόσκειν, to feed or to graze. Nowadays, botanists study approximately 410,000 species of plants of which some 391,000 species are vascular plants. Medieval physic gardens, often attached to monasteries, contained plants of medical importance and they were forerunners of the first botanical gardens attached to universities, founded from the 1540s onwards. One of the earliest was the Padua botanical garden and these gardens facilitated the academic study of plants. Efforts to catalogue and describe their collections were the beginnings of plant taxonomy, in the last two decades of the 20th century, botanists exploited the techniques of molecular genetic analysis, including genomics and proteomics and DNA sequences to classify plants more accurately. Modern botany is a broad, multidisciplinary subject with inputs from most other areas of science, dominant themes in 21st century plant science are molecular genetics and epigenetics, which are the mechanisms and control of gene expression during differentiation of plant cells and tissues. Botany originated as herbalism, the study and use of plants for their medicinal properties, many records of the Holocene period date early botanical knowledge as far back as 10,000 years ago. This early unrecorded knowledge of plants was discovered in ancient sites of human occupation within Tennessee, the early recorded history of botany includes many ancient writings and plant classifications. Examples of early works have been found in ancient texts from India dating back to before 1100 BC, in archaic Avestan writings. His major works, Enquiry into Plants and On the Causes of Plants, constitute the most important contributions to science until the Middle Ages. De Materia Medica was widely read for more than 1,500 years, important contributions from the medieval Muslim world include Ibn Wahshiyyas Nabatean Agriculture, Abū Ḥanīfa Dīnawarīs the Book of Plants, and Ibn Bassals The Classification of Soils. In the early 13th century, Abu al-Abbas al-Nabati, and Ibn al-Baitar wrote on botany in a systematic and scientific manner and these gardens continued the practical value of earlier physic gardens, often associated with monasteries, in which plants were cultivated for medical use. They supported the growth of botany as an academic subject, lectures were given about the plants grown in the gardens and their medical uses demonstrated. Botanical gardens came much later to northern Europe, the first in England was the University of Oxford Botanic Garden in 1621, throughout this period, botany remained firmly subordinate to medicine. German physician Leonhart Fuchs was one of the three German fathers of botany, along with theologian Otto Brunfels and physician Hieronymus Bock, Fuchs and Brunfels broke away from the tradition of copying earlier works to make original observations of their own. Bock created his own system of plant classification, physician Valerius Cordus authored a botanically and pharmacologically important herbal Historia Plantarum in 1544 and a pharmacopoeia of lasting importance, the Dispensatorium in 1546. Naturalist Conrad von Gesner and herbalist John Gerard published herbals covering the medicinal uses of plants, naturalist Ulisse Aldrovandi was considered the father of natural history, which included the study of plants

Leonhart Fuchs
–
Leonhart Fuchs, sometimes spelled Leonhard Fuchs, was a German physician and botanist. His chief notability is as the author of a book about plants and their uses as medicines. It was first published in 1542 in Latin and it has about 500 accurate and detailed drawings of plants, which were printed from woodcuts. The drawings are the books most notable advance on its predecessors, although drawings were in use beforehand in other Herbal books, Fuchs Herbal book proved and emphasized high-quality drawings as the most telling way to specify what a plant name stands for. The botanical genus Fuchsia is named in his honour, and consequently the colour fuchsia, Fuchs was born in 1501 in Wemding in the Duchy of Bavaria. After attending a school in Heilbronn, Fuchs went to the Marienschule in Erfurt, Thuringia at the age of twelve, in 1524 he became Magister Artium in Ingolstadt, and received a doctor of medicine degree in the same year. From 1524-1526 he practiced as a doctor in Munich, until he received a chair of medicine at Ingolstadt in 1526, from 1528-1531 he was the personal physician of Georg, Margrave of Brandenburg-Ansbach in Ansbach. Fuchs was called to Tübingen by Ulrich, Duke of Württemberg in 1533 to help in reforming the University of Tübingen in the spirit of humanism. He created its first medicinal garden in 1535 and served as chancellor seven times, Fuchs died in Tübingen in 1566. Like his medieval predecessors and his contemporaries, Fuchs was heavily influenced by the three Greek and Roman writers on medicine and materia medica, Dioscorides, Hippocrates, and Galen. He wanted to fight the Arab hegemony in medicine, as it had been transmitted by the Medical School of Salerno, but he saw the importance of practical experience as well and offered botanical field days for the students, where he demonstrated the medicinal plants in situ. He founded one of the first German botanical gardens, Fuchs name is preserved by the plant Fuchsia, discovered in the Dominican Republic in the Caribbean in 1696/97 by the French scientist and Minim monk Charles Plumier. He published the first description of Fuchsia triphylla, flore coccineo in 1703 and it is sometimes thought that the color fuchsia is also named for Fuchs. The name of the color fuchsia actually derives from fuchsine, a trade name for the dye, rosaniline hydrochloride. Magenta is another competing trade name for the dye in England. An 1861 article in Répertoire de Pharmacie in fact confirms that the name was chosen for these two reasons and irrelevant of the actual colors of any flowers in the genus Fuchsia. Errata recentiorum medicorum, his first publication, in which he argued for the use of rather than the noxious compounds of arcane ingredients concocted in medieval medicine. Fuchs tried to identify the plants described by the classical authors, over a decade, Fuchs began to prepare for the publication of his herbal

Circaea
–
The genus Circaea contains 7–10 species of flowering plants, known as Enchanters nightshade, in the willowherb family Onagraceae. They are woodland plants occurring throughout the regions of the Northern Hemisphere. Two species are widespread, Broad-leaved Enchanters Nightshade and Alpine Enchanters Nightshade, in addition, there is an intermediate hybrid between these two, and several local species or subspecies, with between eight and 14 forms recognised by different authorities. The hybrid is sterile, persisting only by vegetative reproduction and not producing seeds and this plant spreads its seeds by producing burrs that adhere to clothing, fur and feathers. Circaea is in the family Onagraceae, which also includes willowherbs, evening primroses, the genus is named after the enchantress Circe from Greek mythology, who is supposed to have used enchanters nightshade in her magic. Enchanters nightshade is not related to the family that includes deadly nightshade. Molecular evidence indicates the closest relative to Circaea is the lineage that gave rise to the genus Fuchsia, species Circaea alpina C. alpina subsp.

This species of Fuchsia occurs in temperate climate southern regions of Argentina and Chile, from latitude 32°50 S. to the Straits of Magellan. In Australia, the species is recorded as naturalised in the states of Western Australia, South Australia, New South Wales and this sub-shrub can grow to 10 feet in height and width in frost-free climates, and 4–5 feet where colder. The plant blossoms profusely over a period with many small and tubular pendent flowers, in brilliant shades of red and purple, softer shades of pink and lavender. F. Paul E. Berry, the authority on the genus. It is used for planting in temperate and subtropical gardens and within conservatories, and for containers on patios, balconies, the plants are quite cold-hardy compared to other species from more tropical climates, being deciduous where frosts are light, and only top die back in hard frosts. The profuse drooping flowers are a nectar source attractive to hummingbirds and it has more recently made appearances in France, the Channel Islands and the United Kingdom. Fortunately the fuchsia gall mite doesnt readily survive temperatures under 40°F and there are effective treatments, cultivars of Fuchsia magellanica include, Fuchsia magellanica Molinae - lavender with white flowers. Fuchsia magellanica Riccartonii - dark green leaves with a faint bronze sheen, Fuchsia magellanica Versicolor - small, grey-green leaves variably margined with cream, pink flush when young, red and purple flowers.

Tierra del Fuego

Tierra del Fuego is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan. The archipelago consists of the island, Isla Grande de Tierra del Fuego, with an area of 48,100 km2. Tierra del Fuego is divided between Chile and Argentina, with the controlling the eastern half of the main island. The southernmost extent of the archipelago is at about latitude 55 S, the earliest known human settlement in Tierra del Fuego dates to around 8,000 B. C. Europeans first explored the islands during Ferdinand Magellans expedition of 1520, Tierra del Fuego, today, petroleum extraction dominates economic activity in the north of Tierra del Fuego, while tourism, manufacturing, and Antarctic logistics are important in the south. The earliest human settlement occurred around 8,000 B. C, the Yaghan were some of the earliest known humans to settle in Tierra del Fuego. Archeological sites with characteristics of their culture have found at locations such as Navarino Island. The name Tierra del Fuego derives from the Portuguese explorer Ferdinand Magellan, sailing for the Spanish Crown and he believed he was seeing the many fires of the Yaghan, which were visible from the sea, and that the Indians were waiting in the forests to ambush his armada. In 1525 Francisco de Hoces was the first to speculate that Tierra del Fuego was one or more islands rather than part of what was then called Terra Australis, francis Drake in 1578 and a Dutch VOC expedition in 1616 learned more about the geography. The latter expedition named Cape Horn, on his first voyage with the HMS Beagle in 1830, Robert FitzRoy picked up four native Fuegians, including Jemmy Button and brought them to England. The surviving three were taken to London to meet the King and Queen and were, for a time and they returned to Tierra del Fuego in the Beagle with FitzRoy and Charles Darwin, who made extensive notes about his visit to the islands. During the second half of the 19th century, the archipelago began to come under Chilean, both countries sought to claim the whole archipelago based on de jure Spanish colonial titles. Salesian Catholic missions were established in Río Grande and Dawson Island, anglican missions were established by British colonists at Keppel Island in the Falklands in 1855 and in 1870 at Ushuaia on the main island, which continued to operate through the 19th century. Thomas Bridges learned the language and compiled a 30, 000-word Yaghan grammar and it was published in the 20th century and considered an important ethnological work. An 1879 Chilean expedition led by Ramón Serrano Montaner reported large amounts of gold in the streams. This prompted massive immigration to the island between 1883 and 1909. Numerous Argentines, Chileans and Croatians settled in the main island, julius Popper, a Romanian explorer, was one of the most successful entrepreneurs in the region. Granted rights by the Argentine government to exploit any gold deposits he found in Tierra del Fuego, despite the missionaries efforts, many natives died

Temperateness

In geography, temperate or tepid latitudes of Earth lie between the tropics and the polar regions. The temperatures in these regions are relatively moderate, rather than extremely hot or cold. The north temperate zone extends from the Tropic of Cancer to the Arctic Circle, the south temperate zone extends from the Tropic of Capricorn to the Antarctic Circle. In some climate classifications, the zone is often divided into several smaller climate zones. These include Humid subtropical climate, Mediterranean climate, oceanic, subtropical climates are located between 23. 5° and 35. 0° north or south latitude on the eastern or leeward sides of landmasses. This climate has long, generally hot, summers and short, mild winters and these climates may occur in southern Asia, the southeastern United States, parts of eastern Australia, and in eastern coastal South America. Mediterranean climates, occur between 30° and 42° north and south latitude, on the sides of landmasses. This climate has hot summers and short mild winters, however, seasonal rainfall is the opposite of that of the subtropical humid type. These climates occur near the rimlands of the Mediterranean Sea, in western Australia, in California, the oceanic climates occur in the higher middle latitudes, between 45° and 60° north and south latitude. They are created by the flow from the cool high latitude oceans to their west. This causes the climate to have cool summers and cool winters, annual rainfall is spread throughout the entire year. Regions with this climate include Western Europe, northwestern North America, the Continental climates occur in middle latitudes, between 35° or 40° to 55°. These climates are normally inland or on sides of landmasses. They feature warm to hot summers and cold winters, with a large temperature variation. Regions with this climate include northern temperate Asia, the northern United States, southern Canada, the vast majority of the worlds human population resides in temperate zones, especially in the northern hemisphere, due to its greater mass of land. The richest temperate flora in the world is found in southern Africa, geographical zone Habitat Köppen climate classification Middle latitudes Polar circle Subtropics

Tropical

The tropics are a region of the Earth surrounding the equator. The tropics are also referred to as the zone and the torrid zone. The tropics include all the areas on the Earth where the Sun is at a point directly overhead at least once during the solar year. The tropics are distinguished from the climatic and biomatic regions of Earth, which are the middle latitudes. Tropical is sometimes used in a sense for a tropical climate to mean warm to hot and moist year-round. Many tropical areas have a dry and wet season, the wet season, rainy season or green season, is the time of year, ranging from one or more months, when most of the average annual rainfall in a region falls. Areas with wet seasons are disseminated across portions of the tropics and subtropics, under the Köppen climate classification, for tropical climates, a wet season month is defined as a month where average precipitation is 60 millimetres or more. Tropical rainforests technically do not have dry or wet seasons, since their rainfall is distributed through the year. When the wet season occurs during the season, or summer, precipitation falls mainly during the late afternoon. The wet season is a time when air quality improves, freshwater quality improves and vegetation grows significantly, floods cause rivers to overflow their banks, and some animals to retreat to higher ground. Soil nutrients diminish and erosion increases, the incidence of malaria increases in areas where the rainy season coincides with high temperatures. Animals have adaptation and survival strategies for the wetter regime, unfortunately, the previous dry season leads to food shortages into the wet season, as the crops have yet to mature. Regions within the tropics may well not have a tropical climate, there are alpine tundra and snow-capped peaks, including Mauna Kea, Mount Kilimanjaro, and the Andes as far south as the northernmost parts of Chile and Argentina. Under the Köppen climate classification, much of the area within the tropics is classed not as tropical but as dry including the Sahara Desert. Tropical plants and animals are those native to the tropics. Tropical ecosystems may consist of rainforests, dry forests, spiny forests, desert. There are often significant areas of biodiversity, and species present, particularly in rainforests. In biogeography, the tropics are divided into Paleotropics and Neotropics, together, they are sometimes referred to as the Pantropic

The subtropics are geographic and climate zones located roughly between the tropic circle of latitude at 23.5 latitude and temperate latitudes. Subtropical climates are characterized by warm to hot summers and cool to mild winters with infrequent frost. Subtropical climates can occur at elevations within the tropics, such as in the southern end of the Mexican Plateau and in Vietnam. Six climate classifications use the term to define the various temperature. A great portion of the deserts are located within the subtropics. Within savanna regimes in the subtropics, a wet season is seen annually during the summer, within Mediterranean climate regimes, the wet season occurs during the winter. Areas bordering warm oceans are prone to heavy rainfall from tropical cyclones. Plants such as palms, citrus, mango, lychee, the tropics have been historically defined as lying between the Tropic of Cancer and Tropic of Capricorn, located at 23. 45° north and south latitude respectively. The poleward fringe of the subtropics is located at approximately 40° north and south latitude respectively, northern fringes of the type can go further north due to moderating effects of ocean streams, like in parts of Southern Europe due to heat transported by the Gulf Stream. Several methods have used to define the subtropical climate. In the Trewartha climate classification, a subtropical region should have at least eight months with a temperature greater than 10 °C. According to the Troll-Paffen climate classification, there exists one large subtropical zone named the warm-temperate subtropical zone. According to the E. Neef climate classification, the zone is divided into two parts, Rainy winters of the west sides and Eastern subtropical climate. According to the Wilhelm Lauer & Peter Frankenberg climate classification, the zone is divided into three parts, high-continental, continental, and maritime. According to the Siegmund/Frankenberg climate classification, subtropical is one of six zones in the world. Heating of the earth near the equator leads to large amounts of upward motion and convection along the trough or Intertropical convergence zone. The upper-level divergence over the near-equatorial trough leads to air rising and moving away from the equator aloft, as the air moves towards the Mid-Latitudes, it cools and sinks, which leads to subsidence near the 30th parallel of both hemispheres. This circulation is known as the Hadley cell and leads to the formation of the subtropical ridge, many of the worlds deserts are caused by these climatological high-pressure areas, located within the subtropics

Fuchsia excorticata
–
Fuchsia excorticata, commonly known as tree fuchsia, New Zealand fuchsia and by its Māori name kōtukutuku, is a New Zealand native tree belonging to the family Onagraceae. It is commonly found throughout New Zealand and as far south as the Auckland Islands and it grows from sea level up to about 1,000 m, particularly alongside creeks and rivers. It is easily recognised in its environment by the characteristic appearance of its bark. Its scientific name, excorticata, reflects this distinctive property, F. excorticata is the largest member of the genus Fuchsia, growing to a height of 15 m. It is unusual among New Zealand trees in being deciduous in the parts of its range. The introduction of the common brushtail possum to New Zealand precipitated a decline in this species. F. excorticata appears to be one of the preferred food sources. The small dark purple berry is sweet and juicy and it was favoured by Māori who, unusually, gave the fruit its own name of kōnini, it was also eaten by European settlers in jams and puddings.

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

Deciduous
–
In a more general sense, deciduous means the dropping of a part that is no longer needed or falling away after its purpose is finished. In plants it is the result of natural processes, in botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their leaves for part of the year. In some cases leaf loss coincides with winter—namely in temperate or polar climates, in other parts of the world, including tropical, subtropical, and arid regions, plants lose their leaves during the dry season or other seasons, depending on variations in rainfall. The converse of deciduous is coniferous, where foliage is shed on a different schedule from deciduous trees, plants that are intermediate may be called semi-deciduous, they lose old foliage as new growth begins. Other plants are semi-evergreen and lose their leaves before the growing season. Many deciduous plants flower during the period when they are leafless, the absence of leaves improves wind transmission of pollen for wind-pollinated plants and increases the visibility of the flowers to insects in insect-pollinated plants. This strategy is not without risks, as the flowers can be damaged by frost or, in dry season regions, leaf drop or abscission involves complex physiological signals and changes within plants. The process of photosynthesis steadily degrades the supply of chlorophylls in foliage, the brightest leaf colors are produced when days grow short and nights are cool, but remain above freezing. These other pigments include carotenoids that are yellow, brown, anthocyanin pigments produce red and purple colors, though they are not always present in the leaves. Rather, they are produced in the foliage in late summer, parts of the world that have showy displays of bright autumn colors are limited to locations where days become short and nights are cool. In other parts of the world, the leaves of deciduous trees simply fall off without turning the bright colors produced from the accumulation of anthocyanin pigments, the beginnings of leaf drop starts when an abscission layer is formed between the leaf petiole and the stem. This layer is formed in the spring during active new growth of the leaf, the cells are sensitive to a plant hormone called auxin that is produced by the leaf and other parts of the plant. The elongation of cells break the connection between the different cell layers, allowing the leaf to break away from the plant. It also forms a layer that seals the break, so the plant does not lose sap, in the spring, these proteins are used as a nitrogen source during the growth of new leaves or flowers. Plants with deciduous foliage have advantages and disadvantages compared to plants with evergreen foliage, evergreens suffer greater water loss during the winter and they also can experience greater predation pressure, especially when small. Losing leaves in winter may reduce damage from insects, repairing leaves, removing leaves also reduces cavitation which can damage xylem vessels in plants. This then allows deciduous plants to have xylem vessels with larger diameters, the deciduous characteristic has developed repeatedly among woody plants. Trees include maple, many oaks and nothofagus, elm, aspen, Deciduous shrubs include honeysuckle, viburnum, and many others

In botany, an evergreen is a plant that has leaves throughout the year, always green. This contrasts with deciduous plants, which lose their foliage during the winter or dry season. There are many different kinds of plants, both trees and shrubs. Deciduous trees shed their leaves, usually as an adaptation to a cold or dry/wet season, evergreen trees do lose leaves, but each tree loses its leaves gradually and not all at once. Most warm temperate climate plants are also evergreen, in cool temperate climates, fewer plants are evergreen, with a predominance of conifers, as few evergreen broadleaf plants can tolerate severe cold below about −30 °C. In areas where there is a reason for being deciduous, being evergreen is usually an adaptation to low nutrient levels, deciduous trees lose nutrients whenever they lose their leaves. In warmer areas, species such as pines and cypresses grow on poor soils. In Rhododendron, a genus with many broadleaf evergreens, several species grow in forests but are usually found on highly acidic soil where the nutrients are less available to plants. In taiga or boreal forests, it is too cold for the matter in the soil to decay rapidly, so the nutrients in the soil are less easily available to plants. These conditions favour the growth of more evergreens and make it difficult for deciduous plants to persist. In addition, the shelter provided by existing evergreen plants can make it easier for younger evergreen plants to survive cold and/or drought

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

Hummingbird

Hummingbirds are birds from the Americas that constitute the family Trochilidae. They are among the smallest of birds, most species measuring 7. 5–13 cm, indeed, the smallest extant bird species is a hummingbird, the 5-cm bee hummingbird weighing less than 2.5 g. They are known as hummingbirds because of the sound created by their beating wings which flap at high frequencies audible to humans. They hover in mid-air at rapid wing-flapping rates, typically around 50 times per second, hummingbirds have the highest metabolism of any homeothermic animal. To conserve energy when food is scarce, and nightly when not foraging, they go into torpor, a map of the hummingbird family tree—reconstructed from analysis of 284 of the worlds 338 known species—shows rapid diversification from 22 million years ago. Due to this exceptional evolutionary pattern, as many as 140 hummingbird species can coexist in a specific region, the hummingbird evolutionary tree shows ancestral hummingbirds splitting from insectivorous swifts and treeswifts about 42 million years ago, probably in Eurasia. One key evolutionary factor appears to be an altered taste receptor that enabled hummingbirds to seek nectar, by 22 million years ago the ancestral species of current hummingbirds became established in South America, where environmental conditions stimulated further diversification. The Andes Mountains appear to be a rich environment for hummingbird evolution because diversification occurred simultaneously with mountain uplift over the past 10 million years. Hummingbirds remain in dynamic diversification inhabiting ecological regions across South America, North America, within the same geographic region, hummingbird clades co-evolved with nectar-bearing plant clades, affecting mechanisms of pollination. The same is true for the hummingbird, one of the morphologically most extreme species. Hummingbirds exhibit sexual size dimorphism according to Renschs rule, in males are smaller than females in small species. The extent of sexual size difference varies among clades of hummingbirds. For example, the Mellisugini clade exhibits a large size dimorphism, conversely, the Lophomithini clade displays very little size dimorphism, males and females are similar in size. For males and females of the size, females will tend to have larger beaks. Males tend to be smaller than females, allowing conservation of energy to forage competitively, thus, sexual selection will favor smaller male hummingbirds. Female hummingbirds tend to be larger, requiring energy, with longer beaks that allow for more effective reach into crevices of tall flowers for nectar. Thus females are better at foraging, acquiring flower nectar, directional selection will thus favor the larger hummingbirds in terms of acquiring food. Another evolutionary cause of this sexual dimorphism is that the selective forces from competition for nectar between the sexes of each species are what drive the sexual dimorphism
