Lagoon
–
A lagoon is a shallow body of water separated from a larger body of water by barrier islands or reefs. Lagoons are commonly divided into coastal lagoons and atoll lagoons and they have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries, lagoons are common coastal features around many parts of the world. Lagoons can also be man-made and used for treatment, as is the case for e. g. aerated lagoons. Lagoons are shallow, often elongated bodies of water separated from a body of water by a shallow or exposed shoal, coral reef. Some authorities include fresh water bodies in the definition of lagoon, the distinction between lagoon and estuary also varies between authorities. Richard A. Davis Jr. restricts lagoon to bodies of water with little or no fresh water inflow, and little or no tidal flow, Davis does state that the terms lagoon and estuary are often loosely applied, even in scientific literature. Timothy M. Kusky characterizes lagoons as normally being elongated parallel to the coast, while estuaries are usually drowned river valleys, coastal lagoons are classified as inland bodies of water. Many lagoons do not include lagoon in their common names, in England, The Fleet at Chesil Beach has also been described as a lagoon. In Latin America, the term laguna in Spanish, which translates to. However, sometimes it is used to describe a full-sized lake, such as Laguna Catemaco in Mexico. The brackish water lagoon may be explicitly identified as a coastal lagoon. In Portuguese the same usage is found, lagoa may be a body of sea water. Lagoon is derived from the Italian laguna, which refers to the waters around Venice, Laguna is attested in English by at least 1612, and had been Anglicized to lagune by 1673. In 1697 William Dampier referred to a Lagune or Lake of Salt water on the coast of Mexico, captain James Cook described an island of Oval form with a Lagoon in the middle in 1769. Atoll lagoons form as coral reefs grow upwards while the islands that the reefs surround subside, unlike the lagoons that form shoreward of fringing reefs, atoll lagoons often contain some deep portions. Coastal lagoons form along gently sloping coasts where barrier islands or reefs can develop off-shore, coastal lagoons do not form along steep or rocky coasts, or if the range of tides is more than 4 metres. Due to the slope of the coast, coastal lagoons are shallow

Pacific Ocean
–
The Pacific Ocean is the largest and deepest of the Earths oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by Asia and Australia in the west, the Mariana Trench in the western North Pacific is the deepest point in the world, reaching a depth of 10,911 metres. Both the center of the Water Hemisphere and the Western Hemisphere are in the Pacific Ocean, the oceans current name was coined by Portuguese explorer Ferdinand Magellan during the Spanish circumnavigation of the world in 1521, as he encountered favourable winds on reaching the ocean. He called it Mar Pacífico, which in both Portuguese and Spanish means peaceful sea, important human migrations occurred in the Pacific in prehistoric times. Long-distance trade developed all along the coast from Mozambique to Japan, trade, and therefore knowledge, extended to the Indonesian islands but apparently not Australia. By at least 878 when there was a significant Islamic settlement in Canton much of trade was controlled by Arabs or Muslims. In 219 BC Xu Fu sailed out into the Pacific searching for the elixir of immortality, from 1404 to 1433 Zheng He led expeditions into the Indian Ocean. The east side of the ocean was discovered by Spanish explorer Vasco Núñez de Balboa in 1513 after his expedition crossed the Isthmus of Panama and he named it Mar del Sur because the ocean was to the south of the coast of the isthmus where he first observed the Pacific. Later, Portuguese explorer Ferdinand Magellan sailed the Pacific East to West on a Castilian expedition of world circumnavigation starting in 1519, Magellan called the ocean Pacífico because, after sailing through the stormy seas off Cape Horn, the expedition found calm waters. The ocean was often called the Sea of Magellan in his honor until the eighteenth century, sailing around and east of the Moluccas, between 1525 and 1527, Portuguese expeditions discovered the Caroline Islands, the Aru Islands, and Papua New Guinea. In 1542–43 the Portuguese also reached Japan, in 1564, five Spanish ships consisting of 379 explorers crossed the ocean from Mexico led by Miguel López de Legazpi and sailed to the Philippines and Mariana Islands. The Manila galleons operated for two and a half centuries linking Manila and Acapulco, in one of the longest trade routes in history, Spanish expeditions also discovered Tuvalu, the Marquesas, the Cook Islands, the Solomon Islands, and the Admiralty Islands in the South Pacific. In the 16th and 17th century Spain considered the Pacific Ocean a Mare clausum—a sea closed to other naval powers, as the only known entrance from the Atlantic the Strait of Magellan was at times patrolled by fleets sent to prevent entrance of non-Spanish ships. On the western end of the Pacific Ocean the Dutch threatened the Spanish Philippines, Spain also sent expeditions to the Pacific Northwest reaching Vancouver Island in southern Canada, and Alaska. The French explored and settled Polynesia, and the British made three voyages with James Cook to the South Pacific and Australia, Hawaii, and the North American Pacific Northwest, one of the earliest voyages of scientific exploration was organized by Spain in the Malaspina Expedition of 1789–1794. It sailed vast areas of the Pacific, from Cape Horn to Alaska, Guam and the Philippines, New Zealand, Australia, and the South Pacific. Growing imperialism during the 19th century resulted in the occupation of much of Oceania by other European powers, and later, Japan, in Oceania, France got a leading position as imperial power after making Tahiti and New Caledonia protectorates in 1842 and 1853 respectively. After navy visits to Easter Island in 1875 and 1887, Chilean navy officer Policarpo Toro managed to negotiate an incorporation of the island into Chile with native Rapanui in 1888, by occupying Easter Island, Chile joined the imperial nations

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans 643,801 square kilometres and had a population of almost 67 million people as of January 2017. It is a unitary republic with the capital in Paris. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse, during the Iron Age, what is now metropolitan France was inhabited by the Gauls, a Celtic people. The area was annexed in 51 BC by Rome, which held Gaul until 486, France emerged as a major European power in the Late Middle Ages, with its victory in the Hundred Years War strengthening state-building and political centralisation. During the Renaissance, French culture flourished and a colonial empire was established. The 16th century was dominated by civil wars between Catholics and Protestants. France became Europes dominant cultural, political, and military power under Louis XIV, in the 19th century Napoleon took power and established the First French Empire, whose subsequent Napoleonic Wars shaped the course of continental Europe. Following the collapse of the Empire, France endured a succession of governments culminating with the establishment of the French Third Republic in 1870. Following liberation in 1944, a Fourth Republic was established and later dissolved in the course of the Algerian War, the Fifth Republic, led by Charles de Gaulle, was formed in 1958 and remains to this day. Algeria and nearly all the colonies became independent in the 1960s with minimal controversy and typically retained close economic. France has long been a centre of art, science. It hosts Europes fourth-largest number of cultural UNESCO World Heritage Sites and receives around 83 million foreign tourists annually, France is a developed country with the worlds sixth-largest economy by nominal GDP and ninth-largest by purchasing power parity. In terms of household wealth, it ranks fourth in the world. France performs well in international rankings of education, health care, life expectancy, France remains a great power in the world, being one of the five permanent members of the United Nations Security Council with the power to veto and an official nuclear-weapon state. It is a member state of the European Union and the Eurozone. It is also a member of the Group of 7, North Atlantic Treaty Organization, Organisation for Economic Co-operation and Development, the World Trade Organization, originally applied to the whole Frankish Empire, the name France comes from the Latin Francia, or country of the Franks

Overseas France
–
Overseas France consists of all the French-administered territories outside of the European continent. Their citizens have French nationality and vote for the president of France and they have the right to vote in elections to the European Parliament. From a legal and administrative standpoint, overseas regions are different from overseas collectivities. Overseas regions have exactly the same status as mainland Frances regions, in the French overseas regions, laws cannot be adapted whereas the overseas collectivities are empowered to make their own laws, except in certain areas. The overseas collectivities are governed by elected assemblies and by the French Parliament. Overseas France has an economic zone of 9,821,231 km². Guadeloupe French Guiana Martinique Réunion Mayotte 1976–2003, sui generis overseas territory, 2001–2003, with the designation departmental community, 2003–2011, in the 2009 Mahoran status referendum, Mahorans voted to become an overseas department in 2011, which occurred on March 31,2011. The category of overseas collectivity was created by Frances constitutional reform of March 28,2003, each overseas collectivity has its own statutory laws. French Polynesia In 2004 it was given the designation of overseas country, despite being given the political status of overseas collectivity, Saint Pierre et Miquelon is called collectivité territoriale de Saint-Pierre-et-Miquelon, literally territorial collectivity. It is still referred to as a territoire. Saint Martin, In 2003, the populations of St. Martin, on February 7,2007, the French Parliament passed a bill granting COM status to both jurisdictions. The new status took effect on February 22,2007 when the law was published in the Journal Officiel and they remain part of the European Union, as stated in the Treaty of Lisbon. It is currently the only overseas territory, according to law 2007-224 of February 21,2007, the Scattered Islands in the Indian Ocean constitute the 5th district of TAAF. New Caledonia was classified as an overseas territory beginning in 1946, a New Caledonian citizenship was established, and a gradual transfer of power from the French state to New Caledonia itself was begun, to last from 15 to 20 years. Clipperton Island is a 9 km2 coral atoll located 1,280 km south-west of Acapulco, Mexico and it is held as state private property under the direct authority of the French government, and is administered by Frances Overseas Minister. With 2,691,000 inhabitants in 2013, Overseas France account for 4. 1% of the population of the French Republic and they enjoy a corresponding representation in the two chambers of the French Parliament. In the 13th Legislature, Overseas France is represented by 27 députés in the French National Assembly,2004, Official website Overseas France at DMOZ

Time in France
–
Metropolitan France uses Central European Time and Central European Summer Time. Daylight saving time is observed in Metropolitan France from the last Sunday in March to the last Sunday in October, with its overseas territories, France uses 12 different time zones, more than any other country in the world. The overseas territories of France use different timezones, before 1891, each town and city in Metropolitan France had its own time based on local solar time. In 1891, to avoid complications with railway timetables, time was unified in Metropolitan France, in detail, the railway companies used a unified time which lagged behind Paris solar time by 5 minutes, for the benefit of non-punctual travellers. In 1911, Metropolitan France adopted GMT+0 as its official time, the Vichy authorities kept GMT+1 during the winter of 1940–1941 and adopted GMT+2 in May 1941 in order to unify the railway timetables between occupied and non-occupied Metropolitan France. In 1942,1943, and 1944 the whole of Metropolitan France thus used GMT+2 during the summer, at the Liberation of France in the summer of 1944, Metropolitan France kept GMT+2 as it was the time then used by the Allies. In the winter of 1944–1945, Metropolitan France switched to GMT+1, same as in the United Kingdom, in September 1945, Metropolitan France returned to GMT+1, which the British had already done in July 1945. In 1996, daylight saving time was harmonized throughout the European Union by Directive 2000/84/EC, which moved the end of DST to the last Sunday in October

French language
–
French is a Romance language of the Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages, French has evolved from Gallo-Romance, the spoken Latin in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues doïl—languages historically spoken in northern France and in southern Belgium, French was also influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the Frankish language of the post-Roman Frankish invaders. Today, owing to Frances past overseas expansion, there are numerous French-based creole languages, a French-speaking person or nation may be referred to as Francophone in both English and French. French is a language in 29 countries, most of which are members of la francophonie. As of 2015, 40% of the population is in Europe, 35% in sub-Saharan Africa, 15% in North Africa and the Middle East, 8% in the Americas. French is the fourth-most widely spoken mother tongue in the European Union, 1/5 of Europeans who do not have French as a mother tongue speak French as a second language. As a result of French and Belgian colonialism from the 17th and 18th century onward, French was introduced to new territories in the Americas, Africa, most second-language speakers reside in Francophone Africa, in particular Gabon, Algeria, Mauritius, Senegal and Ivory Coast. In 2015, French was estimated to have 77 to 110 million native speakers, approximately 274 million people are able to speak the language. The Organisation internationale de la Francophonie estimates 700 million by 2050, in 2011, Bloomberg Businessweek ranked French the third most useful language for business, after English and Standard Mandarin Chinese. Under the Constitution of France, French has been the language of the Republic since 1992. France mandates the use of French in official government publications, public education except in specific cases, French is one of the four official languages of Switzerland and is spoken in the western part of Switzerland called Romandie, of which Geneva is the largest city. French is the language of about 23% of the Swiss population. French is also a language of Luxembourg, Monaco, and Aosta Valley, while French dialects remain spoken by minorities on the Channel Islands. A plurality of the worlds French-speaking population lives in Africa and this number does not include the people living in non-Francophone African countries who have learned French as a foreign language. Due to the rise of French in Africa, the total French-speaking population worldwide is expected to reach 700 million people in 2050, French is the fastest growing language on the continent. French is mostly a language in Africa, but it has become a first language in some urban areas, such as the region of Abidjan, Ivory Coast and in Libreville. There is not a single African French, but multiple forms that diverged through contact with various indigenous African languages, sub-Saharan Africa is the region where the French language is most likely to expand, because of the expansion of education and rapid population growth

Spanish language
–
Spanish —also called Castilian —is a Romance language that originated in the Castile region of Spain, with hundreds of millions of native speakers around the world. It is usually considered the worlds second-most spoken native language after Mandarin Chinese and it is one of the few languages to use inverted question and exclamation marks. Spanish is a part of the Ibero-Romance group of languages, which evolved from several dialects of Vulgar Latin in Iberia after the collapse of the Western Roman Empire in the 5th century. Beginning in the early 16th century, Spanish was taken to the colonies of the Spanish Empire, most notably to the Americas, as well as territories in Africa, Oceania, around 75% of modern Spanish is derived from Latin. Greek has also contributed substantially to Spanish vocabulary, especially through Latin, Spanish vocabulary has been in contact from an early date with Arabic, having developed during the Al-Andalus era in the Iberian Peninsula. With around 8% of its vocabulary being Arabic in origin, this language is the second most important influence after Latin and it has also been influenced by Basque as well as by neighboring Ibero-Romance languages. It also adopted words from languages such as Gothic language from the Visigoths in which many Spanish names and surnames have a Visigothic origin. Spanish is one of the six languages of the United Nations. It is the language in the world by the number of people who speak it as a mother tongue, after Mandarin Chinese. It is estimated more than 437 million people speak Spanish as a native language. Spanish is the official or national language in Spain, Equatorial Guinea, speakers in the Americas total some 418 million. In the European Union, Spanish is the tongue of 8% of the population. Spanish is the most popular second language learned in the United States, in 2011 it was estimated by the American Community Survey that of the 55 million Hispanic United States residents who are five years of age and over,38 million speak Spanish at home. The Spanish Constitution of 1978 uses the term castellano to define the language of the whole Spanish State in contrast to las demás lenguas españolas. Article III reads as follows, El castellano es la lengua española oficial del Estado, las demás lenguas españolas serán también oficiales en las respectivas Comunidades Autónomas. Castilian is the official Spanish language of the State, the other Spanish languages as well shall be official in their respective Autonomous Communities. The Spanish Royal Academy, on the hand, currently uses the term español in its publications. Two etymologies for español have been suggested, the Spanish Royal Academy Dictionary derives the term from the Provençal word espaignol, and that in turn from the Medieval Latin word Hispaniolus, from—or pertaining to—Hispania

Atoll
–
An atoll, sometimes called a coral atoll, is a ring-shaped coral reef including a coral rim that encircles a lagoon partially or completely. There may be coral islands/cays on the rim, the coral of the atoll often sits atop the rim of an extinct seamount or volcano which has eroded or subsided partially beneath the water. The lagoon forms over the crater or caldera while the higher rim remains above water or at shallow depths that permit the coral to grow. For the atoll to persist, continued erosion or subsidence must be at a slow enough to permit reef growth upwards and outwards to replace the lost height. The word atoll comes from the Dhivehi word atholhu, meaning an administrative subdivision, the distribution of atolls around the globe is instructive, most of the worlds atolls are in the Pacific Ocean and Indian Ocean. The Atlantic Ocean has no large groups of atolls, other than eight atolls east of Nicaragua that belong to the Colombian department of San Andres and Providencia in the Caribbean. Reef-building corals will thrive only in tropical and subtropical waters of oceans and seas. The northernmost atoll of the world is Kure Atoll at 28°24 N, the southernmost atolls of the world are Elizabeth Reef at 29°58 S, and nearby Middleton Reef at 29°29 S, in the Tasman Sea, both of which are part of the Coral Sea Islands Territory. The next southerly atoll is Ducie Island in the Pitcairn Islands Group, at this latitude coral reefs would not develop without the warming waters of the Gulf Stream. However, Bermuda is termed a pseudo-atoll because its general form, while there is no atoll directly on the equator, the closest atoll to the Equator is Aranuka of Kiribati, with its southern tip just 12 km north of the equator. In most cases, the area of an atoll is very small in comparison to the total area. Atoll islands are low lying, with their elevations less than 5 meters, measured by total area, Lifou is the largest raised coral atoll of the world, followed by Rennell Island. More sources however list as the largest atoll in the world in terms of land area Kiritimati, the remains of an ancient atoll as a hill in a limestone area is called a reef knoll. The second largest atoll by dry land area is Aldabra with 155 km², the largest atoll in terms of island numbers is Huvadhu Atoll in the south of the Maldives with 255 islands. In 1842, Charles Darwin explained the creation of coral atolls in the southern Pacific Ocean based upon observations made during a voyage aboard the HMS Beagle from 1831 to 1836. In time, subsidence carries the old volcano below the ocean surface, at this point, the island has become an atoll. Atolls are the product of the growth of marine organisms. Volcanic islands located beyond the water temperature requirements of hermatypic organisms become seamounts as they subside and are eroded away at the surface

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

Paris is the capital and most populous city of France. It has an area of 105 square kilometres and a population of 2,229,621 in 2013 within its administrative limits, the agglomeration has grown well beyond the citys administrative limits. By the 17th century, Paris was one of Europes major centres of finance, commerce, fashion, science, and the arts, and it retains that position still today. The aire urbaine de Paris, a measure of area, spans most of the Île-de-France region and has a population of 12,405,426. It is therefore the second largest metropolitan area in the European Union after London, the Metropole of Grand Paris was created in 2016, combining the commune and its nearest suburbs into a single area for economic and environmental co-operation. Grand Paris covers 814 square kilometres and has a population of 7 million persons, the Paris Region had a GDP of €624 billion in 2012, accounting for 30.0 percent of the GDP of France and ranking it as one of the wealthiest regions in Europe. The city is also a rail, highway, and air-transport hub served by two international airports, Paris-Charles de Gaulle and Paris-Orly. Opened in 1900, the subway system, the Paris Métro. It is the second busiest metro system in Europe after Moscow Metro, notably, Paris Gare du Nord is the busiest railway station in the world outside of Japan, with 262 millions passengers in 2015. In 2015, Paris received 22.2 million visitors, making it one of the top tourist destinations. The association football club Paris Saint-Germain and the rugby union club Stade Français are based in Paris, the 80, 000-seat Stade de France, built for the 1998 FIFA World Cup, is located just north of Paris in the neighbouring commune of Saint-Denis. Paris hosts the annual French Open Grand Slam tennis tournament on the red clay of Roland Garros, Paris hosted the 1900 and 1924 Summer Olympics and is bidding to host the 2024 Summer Olympics. The name Paris is derived from its inhabitants, the Celtic Parisii tribe. Thus, though written the same, the name is not related to the Paris of Greek mythology. In the 1860s, the boulevards and streets of Paris were illuminated by 56,000 gas lamps, since the late 19th century, Paris has also been known as Panam in French slang. Inhabitants are known in English as Parisians and in French as Parisiens and they are also pejoratively called Parigots. The Parisii, a sub-tribe of the Celtic Senones, inhabited the Paris area from around the middle of the 3rd century BC. One of the areas major north-south trade routes crossed the Seine on the île de la Cité, this place of land and water trade routes gradually became a town

Papeete
–
Papeete is the capital of French Polynesia, an overseas country of France in the Pacific Ocean. The commune of Papeete is located on the island of Tahiti, in the subdivision of the Windward Islands. The French High Commissioner also resides in Papeete, the Windward Islands are themselves part of the Society Islands. The name Papeete means water from a basket, the urban area of Papeete had a total population of 133,627 inhabitants at the August 2012 census,25,769 of whom lived in the commune of Papeete proper. In 1983, The Church of Jesus Christ of Latter-day Saints built the Papeete Tahiti Temple here because of the number of members in the region. On 5 September 1995 the government of Jacques Chirac conducted the first of the last series of nuclear test detonations off the shores of Moruroa. A resulting riot in Papeete lasted for two days and damaged the airport, injured 40 people, and scared away tourism for some time. There are very busy streets in the center, and sometimes traffic can be a problem since the streets are very small. There is a freeway that starts close to the town starting with Pomare Boulevard. By air, the people would use the Faaa International Airport, from there they could either take Air Tahiti to go to another island of the territory or take a plane like Air Tahiti Nui to go international. By sea, they would either take Moorea ferries to go to Moorea or the Bora Bora cruiseline to go to Bora Bora. The urban area of Papeete has a population of 133,627 inhabitants at the August 2012 census,25,769 of whom lived in the commune of Papeete proper. 96. 5% reported that they could read and write it.

Mexico, officially the United Mexican States, is a federal republic in the southern half of North America. It is bordered to the north by the United States, to the south and west by the Pacific Ocean, to the southeast by Guatemala, Belize, and the Caribbean Sea, and to the east by the Gulf of Mexico. Covering almost two million square kilometers, Mexico is the sixth largest country in the Americas by total area, Mexico is a federation comprising 31 states and a federal district that is also its capital and most populous city. Other metropolises include Guadalajara, Monterrey, Puebla, Toluca, Tijuana, pre-Columbian Mexico was home to many advanced Mesoamerican civilizations, such as the Olmec, Toltec, Teotihuacan, Zapotec, Maya and Aztec before first contact with Europeans. In 1521, the Spanish Empire conquered and colonized the territory from its base in Mexico-Tenochtitlan, Three centuries later, this territory became Mexico following recognition in 1821 after the colonys Mexican War of Independence. The tumultuous post-independence period was characterized by instability and many political changes. The Mexican–American War led to the cession of the extensive northern borderlands, one-third of its territory. The Pastry War, the Franco-Mexican War, a civil war, the dictatorship was overthrown in the Mexican Revolution of 1910, which culminated with the promulgation of the 1917 Constitution and the emergence of the countrys current political system. Mexico has the fifteenth largest nominal GDP and the eleventh largest by purchasing power parity, the Mexican economy is strongly linked to those of its North American Free Trade Agreement partners, especially the United States. Mexico was the first Latin American member of the Organisation for Economic Co-operation and Development and it is classified as an upper-middle income country by the World Bank and a newly industrialized country by several analysts. By 2050, Mexico could become the fifth or seventh largest economy. The country is considered both a power and middle power, and is often identified as an emerging global power. Due to its culture and history, Mexico ranks first in the Americas. Mexico is a country, ranking fourth in the world by biodiversity. In 2015 it was the 9th most visited country in the world, Mexico is a member of the United Nations, the World Trade Organization, the G8+5, the G20, the Uniting for Consensus and the Pacific Alliance. Mēxihco is the Nahuatl term for the heartland of the Aztec Empire, namely, the Valley of Mexico, and its people, the Mexica and this became the future State of Mexico as a division of New Spain prior to independence. It is generally considered to be a toponym for the valley became the primary ethnonym for the Aztec Triple Alliance as a result. After New Spain won independence from Spain, representatives decided to name the new country after its capital and this was founded in 1524 on top of the ancient Mexica capital of Mexico-Tenochtitlan

Exclusive economic zone
–
It stretches from the baseline out to 200 nautical miles from its coast. In colloquial usage, the term may include the continental shelf, the term does not include either the territorial sea or the continental shelf beyond the 200 nmi limit. The surface waters, as can be seen in the map, are international waters, generally, a states exclusive economic zone is an area beyond and adjacent to the territorial sea, extending seaward to a distance of no more than 200 nautical miles out from its coastal baseline. The exception to this occurs when exclusive economic zones would overlap. When an overlap occurs, it is up to the states to delineate the actual maritime boundary, generally, any point within an overlapping area defaults to the nearest state. A states exclusive economic zone starts at the edge of its territorial sea. The exclusive economic zone stretches much further into sea than the territorial waters, thus, the exclusive economic zones includes the contiguous zone. The idea of allotting nations EEZs to give more control of maritime affairs outside territorial limits gained acceptance in the late 20th century. Initially, a countrys sovereign territorial waters extended 3 nautical miles or 6 km beyond the shore, in modern times, a countrys sovereign territorial waters extend to 12 nautical miles beyond the shore. One of the first assertions of exclusive jurisdiction beyond the territorial seas was made by the United States in the Truman Proclamation of September 28,1945. The exact extent of economic zones is a common source of conflicts between states over marine waters. One well-known example of such dispute was the Cod Wars between the United Kingdom and Iceland, Norway and Russia dispute both territorial sea and EEZ with regard to the Svalbard archipelago as it affects Russias EEZ due to its unique treaty status. A treaty was agreed in principle in April 2010 between the two states and subsequently ratified, resolving this demarcation dispute, the agreement was signed in Murmansk on September 15,2010. The South China Sea is the site of a dispute between several neighboring nations. Croatias ZERP in the Adriatic Sea caused friction with Italy and Slovenia, a wedge-shaped section of the Beaufort Sea is disputed between Canada and the United States, as the area reportedly contains substantial oil reserves. France claims a portion of Canadas EEZ for Saint-Pierre-et-Miquelon based on a new definition of the continental shelf, Saint-Pierre-et-Miquelon is entirely surrounded by Canadas EEZ. Mauritius claims EEZ for Tromelin from France and EEZ for British Indian Ocean Territory from the UK, Northern Cyprus claims a portion of Cyprus EEZ overlaps with that of Northern Cyprus in the south/southeastern part of the Cyprus island. Turkey claims a portion of Cypruss EEZ overlaps with its own EEZ, Lebanon claims that the agreement between Cyprus and Israel overlapped its own EEZ

Nicaragua
–
Nicaragua, officially the Republic of Nicaragua, is the largest country in the Central American isthmus. Nicaraguas capital, Managua, is the countrys largest city and the third-largest city in Central America, the multi-ethnic population of six million includes indigenous peoples, Europeans, Africans, and Asians. Native tribes on the eastern coast speak their own languages, the Spanish Empire conquered the region in the 16th century. Nicaragua gained independence from Spain in 1821, since its independence, Nicaragua has undergone periods of political unrest, dictatorship, and fiscal crisis—the most notable causes that led to the Nicaraguan Revolution of the 1960s and 1970s. Nicaragua is a democratic republic. The biological diversity, warm climate and active volcanoes make Nicaragua an increasingly popular tourist destination. The name Nicaragua was coined by Spanish colonists based on the name Nicarao, when Spaniard Gil González Dávila came to Nicaragua in 1521 he found in the areas between Rivas and San Jorge the first pre-Columbian natives of Nicaragua. At the time the city was called Quauhcapolca and the cacique leaders name was Macuilmiquiztli. The Pipil migrated to Nicaragua from central Mexico after 500 BC, meanwhile, the Caribbean coast of Nicaragua was inhabited by other peoples, mostly Chibcha language groups. They had coalesced in Central America and migrated also to present-day northern Colombia and they lived a life based primarily on hunting and gathering. In 1502, Christopher Columbus became the first European known to have reached what is now Nicaragua as he sailed southeast toward the Isthmus of Panama, on his fourth voyage, Columbus explored the Miskito Coast on the Atlantic side of Nicaragua. The Spanish attempted to convert all three tribes to Christianity, Nicaragua and Nicarao and their people converted, but Dirangen, however, did not, the first attempt to conquer what is now known as Nicaragua was by Gil González Dávila, who arrived in Panama in January 1520. The first Spanish permanent settlements were founded in 1524, conquistador Francisco Hernández de Córdoba founded two of Nicaraguas principal towns in 1524, Granada on Lake Nicaragua was the first settlement, followed by León at a location west of Lake Managua. Córdoba soon built defenses for the cities and fought against incursions by other conquistadors, Córdoba was later publicly beheaded following a power struggle with Pedro Arias Dávila. His tomb and remains were discovered in 2000 in the ruins of León Viejo, the clashes among Spanish forces did not impede their destruction of the indigenous people and their culture. The series of battles came to be known as the War of the Captains, Pedro Arias Dávila was a winner, although he had lost control of Panama, he moved to Nicaragua and successfully established his base in León. Through adroit diplomatic machinations, he became the first governor of the colony, many indigenous people died as a result of new infectious diseases, compounded by neglect by the Spaniards, who controlled their subsistence. In 1610, the Momotombo volcano erupted, destroying the capital and it was rebuilt northwest of what is now known as the ruins of Old León

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

Ecuador
–
Ecuador also includes the Galápagos Islands in the Pacific, about 1,000 kilometres west of the mainland. What is now Ecuador was home to a variety of Amerindian groups that were incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, Spanish is the official language and is spoken by a majority of the population, though 13 Amerindian languages are also recognized, including Quichua and Shuar. The capital city is Quito, while the largest city is Guayaquil, in reflection of the countrys rich cultural heritage, the historical center of Quito was declared a UNESCO World Heritage Site in 1978. Cuenca, the third-largest city, was declared a World Heritage Site in 1999 as an outstanding example of a planned. Ecuador has an economy that is highly dependent on commodities, namely petroleum. The country is classified as a medium-income country, Ecuador is a democratic presidential republic. The new constitution of 2008 is the first in the world to recognize legally enforceable Rights of Nature, Ecuador is also known for its rich ecology, hosting many endemic plants and animals, such as those of the Galápagos Islands. It is one of 17 megadiverse countries in the world, various peoples had settled in the area of the future Ecuador before the arrival of the Incas. They developed different languages while emerging as unique ethnic groups, even though their languages were unrelated, these groups developed similar groups of cultures, each based in different environments. Over time these groups began to interact and intermingle with each other so that groups of families in one area became one community or tribe, with a similar language and culture. Many civilizations arose in Ecuador, such as the Valdivia Culture and Machalilla Culture on the coast, the Quitus, each civilization developed its own distinctive architecture, pottery, and religious interests. Eventually, through wars and marriage alliances of their leaders, a group of nations formed confederations, one region consolidated under a confederation called the Shyris, which exercised organized trading and bartering between the different regions. Its political and military came under the rule of the Duchicela blood-line. The native confederations that gave them the most problems were deported to distant areas of Peru, Bolivia, similarly, a number of loyal Inca subjects from Peru and Bolivia were brought to Ecuador to prevent rebellion. Thus, the region of highland Ecuador became part of the Inca Empire in 1463 sharing the same language, in contrast, when the Incas made incursions into coastal Ecuador and the eastern Amazon jungles of Ecuador, they found both the environment and indigenous people more hostile. Moreover, when the Incas tried to subdue them, these indigenous people withdrew to the interior, as a result, Inca expansion into the Amazon basin and the Pacific coast of Ecuador was hampered. The indigenous people of the Amazon jungle and coastal Ecuador remained relatively autonomous until the Spanish soldiers, the Amazonian people and the Cayapas of Coastal Ecuador were the only groups to resist Inca and Spanish domination, maintaining their language and culture well into the 21st century

Socorro Island
–
Socorro Island is a small volcanic island in the Revillagigedo Islands, a Mexican possession lying some 600 kilometers off the countrys western coast at 18°48N, 110°59W. The size is 16.5 by 11.5 km and it is the largest of the four islands of the Revillagigedo Archipelago. The island rises abruptly from the sea to 1,050 meters in elevation at its summit, Isla Socorro is a shield volcano. The island is part of the northern Mathematicians Ridge, a ridge that became largely inactive 3.5 million years ago when activity moved to the East Pacific Rise. All four islands along with the many seamounts on the ridge are post-abandonment alkaline volcanoes, Socorro Island is unusual in that it is the only dominantly silicic peralkaline volcanic island in the Pacific Ocean. It most recently erupted in late January-early February,1993, which was a flank eruption off the coast from Punta Tosca. An earlier eruption was on May 21,1951, earlier eruptions probably occurred in 1905,1896 and 1848, the initial volcanic event probably occurred in 3090 BC +/-500 years. Mount Evermann is the given to the summit dome complex. The islands surface is broken by furrows, small craters, and numerous ravines, there is a naval station 18. 728°N110. 952°W /18.728, -110. The station is served by a dock, a helipad and airport Isla Socorro, located six kilometers to the north, at 18. 773°N110. 931°W /18.773. There is a water spring about 5 km northwest of Cabo Regla, at the shoreline of Ensenada Grayson. This is brackish or even covered by the sea at high tide, no evidence of human habitation on Socorro exists before its discovery by Spanish explorers. Hernando de Grijalva and his crew discovered an island on 19 December 1533. At the beginning of the century, Barton Warren Evermann. The most comprehensive biological collections were obtained at this time, the volcano on Socorro was renamed in his honor. Archie Smith, an American laborer from San Diego, was abandoned on the island for one month in 1929 before being rescued by a fishing boat. In September 1997, the island was struck by Hurricane Linda, the lowlands of Socorro – except on the northern, more humid side – are covered with thick shrubland, consisting mainly of endemic Croton masonii and a cactus, probably Engelmanns prickly pear. Above 650 metres and on the side, a richer vegetation occurs

Revillagigedo Islands
–
The Revillagigedo Islands or Revillagigedo Archipelago are a group of four volcanic islands in the Pacific Ocean, known for their unique ecosystem. They lie approximately 390 kilometres southwest of Cabo San Lucas, the tip of the Baja California Peninsula. They are located around 18°49′N 112°46′W, the islands have been part of Manzanillo municipality of the Mexican state of Colima since 1861, but are nevertheless under Mexican federal jurisdiction. In July 2016, the Revillagigedo Archipelago were inscribed as a World Heritage Site, the total area is 157.81 km2, spread over an east-to-west extent of about 420 km. A naval station in the south of Socorro Island has a population of 45, on Clarión is a small naval garrison with 9 men. The islands are named after Don Juan Vicente de Güemes, 2nd Count of Revillagigedo, the three eastern islands are called the inner islands. They fall in the time zone UTC-7, while the part of Colima is UTC-6. Clarión is comparatively far to the west, by more than 200 km in comparison with the inner islands, the Revillagigedo Islands are one of three Mexican island groups in the Pacific Ocean that are not on the continental shelf, the others are Guadalupe Island and Rocas Alijos. No evidence of habitation on Socorro exists before its discovery by Spanish explorers. In November 1542, Ruy López de Villalobos, while exploring new routes across the Pacific, rediscovered Inocentes and Santo Tomás, Villalobos was the first to report sighting of Roca Partida Island giving it its present-day name. In 1608, Martín Yañez de Armida, in charge of expedition, visited Anublada. In 1779 José Camacho was the first to report sighting of the island remaining, Santa Rosa was later renamed Clarion after the vessel commanded by Henry Gyzelaar at that time. On 25 July 1861, President Benito Juárez signed a decree awarding territorial control over the four islands to the state of Colima. His plan was to build an offshore penitentiary on Isla Socorro, although this never happened, at the beginning of the twentieth century, Dr. Barton Warren Evermann, director of the California Academy of Sciences in San Francisco, California, promoted the scientific exploration of the islands. The most comprehensive biological collections were obtained at this time, the volcano on Isla Socorro was renamed in his honor. In 1957 the Mexican Navy established a base on Socorro and has had a permanent presence on the island since then. A tiny outpost also exists on Clarión, as noted above, on 21 March 1972, Pablo Silva García became the first governor of Colima to visit his states island territories. A plaque was unveiled to mark the event and cement Colimas claim, the seas surrounding the larger islands are popular with scuba divers, a variety of marine life such as cetaceans, sharks and manta rays can be observed

Coconut
–
The coconut tree is a member of the family Arecaceae and the only species of the genus Cocos. The term coconut can refer to the coconut palm or the seed, or the fruit. The spelling cocoanut is a form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning head or skull, coconuts are known for their great versatility, as evidenced by many traditional uses, ranging from food to cosmetics. They form a part of the diets of many people in the tropics and subtropics. Coconuts are distinct from other fruits for their quantity of water. When mature, they can be used as seed nuts or processed to give oil from the kernel, charcoal from the hard shell, the endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, when dried, the coconut flesh is called copra. The oil and milk derived from it are used in cooking and frying, as well as in soaps. The husks and leaves can be used as material to make a variety of products for furnishing and decorating, the coconut also has cultural and religious significance in certain societies, particularly in India, where it is used in Hindu rituals. Cocos nucifera is a palm, growing up to 30 m tall, with pinnate leaves 4–6 m long. Coconuts are generally classified into two types, tall and dwarf. On fertile soil, a coconut palm tree can yield up to 75 fruits per year. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers, the exocarp, mesocarp, and endocarp, the exocarp and mesocarp make up the husk of the coconuts. Coconuts sold in the shops of nontropical countries often have had the exocarp removed, the mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores or eyes that are visible on its outside surface once the husk is removed. A full-sized coconut weighs about 1.44 kg and it takes around 6,000 full-grown coconuts to produce a tonne of copra

Volcano
–
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earths volcanoes occur because its crust is broken into 17 major, therefore, on Earth, volcanoes are generally found where tectonic plates are diverging or converging. This type of volcanism falls under the umbrella of plate hypothesis volcanism, Volcanism away from plate boundaries has also been explained as mantle plumes. These so-called hotspots, for example Hawaii, are postulated to arise from upwelling diapirs with magma from the boundary,3,000 km deep in the Earth. Volcanoes are usually not created where two plates slide past one another. Erupting volcanoes can pose hazards, not only in the immediate vicinity of the eruption. Historically, so-called volcanic winters have caused catastrophic famines, the word volcano is derived from the name of Vulcano, a volcanic island in the Aeolian Islands of Italy whose name in turn comes from Vulcan, the god of fire in Roman mythology. The study of volcanoes is called volcanology, sometimes spelled vulcanology, at the mid-oceanic ridges, two tectonic plates diverge from one another as new oceanic crust is formed by the cooling and solidifying of hot molten rock. Most divergent plate boundaries are at the bottom of the oceans, therefore, most volcanic activity is submarine, black smokers are evidence of this kind of volcanic activity. Where the mid-oceanic ridge is above sea-level, volcanic islands are formed, for example, subduction zones are places where two plates, usually an oceanic plate and a continental plate, collide. In this case, the plate subducts, or submerges under the continental plate forming a deep ocean trench just offshore. In a process called flux melting, water released from the subducting plate lowers the temperature of the overlying mantle wedge. This magma tends to be very viscous due to its high content, so it often does not reach the surface. When it does reach the surface, a volcano is formed, typical examples of this kind of volcano are Mount Etna and the volcanoes in the Pacific Ring of Fire. Because tectonic plates move across them, each volcano becomes dormant and is eventually re-formed as the plate advances over the postulated plume and this theory is currently under criticism, however. The most common perception of a volcano is of a mountain, spewing lava and poisonous gases from a crater at its summit, however. The features of volcanoes are more complicated and their structure. Some volcanoes have rugged peaks formed by lava domes rather than a summit crater while others have features such as massive plateaus

French Navy
–
The French Navy, informally La Royale, is the maritime arm of the French Armed Forces. As of June 2014, the French Navy employed a total of 36,776 personnel, the reserve element of the French Navy consisted of 4,827 personnel of the Operational Reserve. The French naval fleet includes more than a hundred vessels and nuclear type submarines, the history of the French Navy dates back to the History of the French Navy of Antiquity to the Renaissance, part of the History of the French Navy. The French Royal Navy was quasi inexistent prior 1624, the Ordre de Saint-Jean de Jérusalem, which was both a religious and military order, had its own respective international war fleet which assured the policing of the seas in the Mediterranean. The members which had satisfied obligations for periods in service at sea fulfilling their service, were granted the rank of Knights Hospitaller, however, many considered the naval service formation to integrate later, while being well formed, their respective navy. The Ordre de Saint-Jean de Jérusalem was one of the ancestors of the French naval schools and in principal, the Order accordingly formed most of the ships Captains, Officers of the French Royal Navy and Admirals of the Marine française de guerre de la Méditerranée. During the Revolution, the French Navy succeeded to the French Royal Navy, under the First French Empire and the Second French Empire, the navy was designated as the Imperial French Navy. The French Navy is still designated today familiarly as La Royale and this expression was used by commercial sailors due to their military service at the corps of the navy by the institution of maritime inscription. The implementation then of the Ministère de la Marine later the de la Marine de guerre française at rue Royale. The symbol of the French Navy, which was since origin a golden anchor » and this symbol featured on all naval vessels, the arms, uniforms, the couriers, equipment, and general arms of the navy. This symbol was replaced in 1990 by a logo featuring a bow section of a warship with two ascending red and blue spray foams, and the inscription Marine nationale. The Chief of Staff of the French Navy was Admiral Bernard Louzeau, the navy became a consistent instrument of national power around the seventeenth century with Richelieus efforts under Louis XIII, and Colberts under Louis XIV. Under the tutelage of the Sun King, the French Navy was well-financed and -equipped, managing to score several victories in the Nine Years War against the Royal Navy. Financial troubles, however, forced the navy back to port and allowed the English, before the Nine Years War, in the Franco-Dutch War, it managed to score a decisive victory over a combined Spanish-Dutch fleet at the Battle of Palermo. The French Navy scored various successes, as in the campaigns led in the Atlantic by Picquet de la Motte, in 1766, Bougainville led the first French circumnavigation. During the American Revolutionary War the French Navy played a role in supporting the Americans. French warships participated in the battle by bombarding British ground forces, in India, Suffren waged campaigns against the British, successfully contending for supremacy against Vice-Admiral Sir Edward Hughes. In the Mediterranean, the French Navy waged a campaign during a 1798 French invasion of Egypt

Amateur radio
–
The amateur radio service is established by the International Telecommunication Union through the International Telecommunication Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual stations licenses with a call sign. Prospective amateur operators are tested for their understanding of key concepts in electronics, according to an estimate made in 2011 by the American Radio Relay League, two million people throughout the world are regularly involved with amateur radio. About 830,000 amateur radio stations are located in IARU Region 2 followed by IARU Region 3 with about 750,000 stations, a significantly smaller number, about 400,000, are located in IARU Region 1. The origins of amateur radio can be traced to the late 19th century, the First Annual Official Wireless Blue Book of the Wireless Association of America, produced in 1909, contains a list of amateur radio stations. This radio callbook lists wireless telegraph stations in Canada and the United States, as with radio in general, amateur radio was associated with various amateur experimenters and hobbyists. Amateur radio enthusiasts have significantly contributed to science, engineering, industry, research by amateur operators has founded new industries, built economies, empowered nations, and saved lives in times of emergency. Ham radio can also be used in the classroom to teach English, map skills, geography, math, science, the term ham radio was first a pejorative that mocked amateur radio operators with a 19th-century term for being bad at something, like ham-fisted or ham actor. It had already used for bad wired telegraph operators. Subsequently, the community adopted it as a moniker, much like the Know-Nothing Party, or other groups. Other, more entertaining explanations have grown up throughout the years, the many facets of amateur radio attract practitioners with a wide range of interests. Many amateurs begin with a fascination of radio communication and then combine other personal interests to make pursuit of the hobby rewarding, some of the focal areas amateurs pursue include radio contesting, radio propagation study, public service communication, technical experimentation, and computer networking. Amateur radio operators use various modes of transmission to communicate, the two most common modes for voice transmissions are frequency modulation and single sideband. FM offers high quality audio signals, while SSB is better at long distance communication when bandwidth is restricted. Radiotelegraphy using Morse code, also known as CW from continuous wave, is the extension of landline telegraphy developed by Samuel Morse. Morse, using internationally agreed message encodings such as the Q code, a similar legacy mode popular with home constructors is amplitude modulation, pursued by many vintage amateur radio enthusiasts and aficionados of vacuum tube technology. Demonstrating a proficiency in Morse code was for years a requirement to obtain an amateur license to transmit on frequencies below 30 MHz. Following changes in regulations in 2003, countries are no longer required to demand proficiency

Water stagnation
–
Water stagnation occurs when water stops flowing. Stagnant water can be an environmental hazard. Malaria and dengue are among the dangers of stagnant water. Stagnant water can be dangerous for drinking because it provides a better incubator than running water for many kinds of bacteria, stagnant water is often contaminated with human and animal feces, particularly in deserts or other areas of low rain. Stagnant water may be classified into the basic, although overlapping, types, Water body stagnation Surface. The water may be trapped in human artifacts, as well as in natural containers, such as tree trunks. To avoid ground and surface water stagnation, drainage of surface, areas with a shallow water table are more susceptible to ground water stagnation due to the lower availability of natural soil drainage. Some plants prefer flowing water, while others, such as lotuses, various anaerobic bacteria are commonly found in stagnant water. For this reason, pools of stagnant water have historically used in processing hemp and some other fiber crops. Several weeks of soaking makes bast fibers easily separable due to bacterial, dragonfly nymphs Fly maggots Mosquito larvae Nepidae Algae Biofilm A number of species of frogs prefer stagnant water.

Fresh water
–
Fresh water is generally characterized by having low concentrations of dissolved salts and other total dissolved solids. The term specifically excludes seawater and brackish water although it does include mineral-rich waters such as chalybeate springs, the term sweet water has been used to describe fresh water in contrast to salt water. The term fresh water does not have the meaning as potable water. Much of the fresh water and ground water is unsuitable for drinking without some form of purification because of the presence of chemical or biological contaminants. It may also be in contact with the underlying underground water. The majority of water on Earth is in ice caps. The source of almost all water is precipitation from the atmosphere, in the form of mist, rain. Fresh water falling as mist, rain or snow contains materials dissolved from the atmosphere and material from the sea, in some cases this acid rain results in pollution of lakes and rivers. In coastal areas fresh water may contain significant concentrations of salts derived from the sea if windy conditions have lifted drops of seawater into the rain-bearing clouds. This can give rise to elevated concentrations of sodium, chloride, magnesium, significant quantities of iron may be transported in this way including the well-documented transfer of iron-rich rainfall falling in Brazil derived from sand-storms in the Sahara in north Africa. Water is an issue for the survival of all living organisms. Some can use water but many organisms including the great majority of higher plants. Out of all the water on Earth, saline water in oceans, seas and saline groundwater make up about 97% of it. Freshwater lakes contain about 87% of this surface water, including 29% in the African Great Lakes, 20% in Lake Baikal in Russia, 21% in the North American Great Lakes. Swamps have most of the balance only a small amount in rivers. In areas with no water on the ground surface, fresh water derived from precipitation may, because of its lower density. Most of the fresh water is frozen in ice sheets. Many areas suffer from lack of distribution of water, such as deserts

Eutrophication
–
Eutrophication, or more precisely hypertrophication, is the enrichment of a water body with nutrients, usually with an excess amount of nutrients. This process induces growth of plants and algae and due to the biomass load, one example is the bloom or great increase of phytoplankton in a water body as a response to increased levels of nutrients. Eutrophication is almost always induced by the discharge of phosphate-containing detergents, fertilizers, or sewage, Eutrophication arises from the oversupply of nutrients, which leads to overgrowth of plants and algae. After such organisms die, the degradation of their biomass consumes the oxygen in the water. According to Ullmanns Encyclopedia, the limiting factor for eutrophication is phosphate. Phosphorus is a nutrient for plants to live, and is the limiting factor for plant growth in many freshwater ecosystems. Phosphate adheres tightly to soil, so it is transported by erosion. Once translocated to lakes, the extraction of phosphate into water is slow, the sources of these excess phosphates are phosphates in detergent, industrial/domestic run-offs, and fertilizers. With the phasing out of phosphate-containing detergents in the 1970s, industrial/domestic run-off, cultural Eutrophication is the process that speeds up natural eutrophication because of human activity. Extra nutrients are supplied by treatment plants, golf courses, fertilizers, farms. When algae die, they decompose and the contained in that organic matter are converted into inorganic form by microorganisms. This decomposition process consumes oxygen, which reduces the concentration of dissolved oxygen, the depleted oxygen levels in turn may lead to fish kills and a range of other effects reducing biodiversity. Nutrients may become concentrated in a zone and may only be made available again during autumn turn-over or in conditions of turbulent flow. The water becomes cloudy, typically coloured a shade of green, yellow, brown, Eutrophication also decreases the value of rivers, lakes and aesthetic enjoyment. Health problems can occur where eutrophic conditions interfere with drinking water treatment, human activities can accelerate the rate at which nutrients enter ecosystems. Elevated levels of compounds of nitrogen can increase nitrogen availability. Phosphorus is often regarded as the culprit in cases of eutrophication in lakes subjected to point source pollution from sewage pipes. The concentration of algae and the state of lakes correspond well to phosphorus levels in water

Potable
–
Drinking water, also known as potable water or improved drinking water, is water that is safe to drink or to use for food preparation, without risk of health problems. Globally, in 2015, 91% of people had access to suitable for drinking. Nearly 4.2 billion had access to tap water while another 2.4 billion had access to wells or public taps,1.8 billion people still use an unsafe drinking water source which may be contaminated by feces. This can result in infectious diarrhea such as cholera and typhoid among others, the amount of drinking water required is variable. It depends on activity, age, health issues. It is estimated that the average American drinks about one litre of water a day with 95% drinking less than three litres per day, for those working in a hot climate, up to 16 liters a day may be required. Water makes up about 60% of weight in men and 55% of weight in women, infants are about 70% to 80% water while the elderly are around 45%. Typically in developed countries, tap water meets drinking water quality standards, other typical uses include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation and its use for irrigation however may be associated with risks. Water may also be due to levels of toxins or suspended solids. Reduction of waterborne diseases and development of water resources is a major public health goal in developing countries. Bottled water is sold for consumption in most parts of the world. The word potable came into English from the Late Latin potabilis, the amount of drinking water required is variable. It depends on activity, age, health, and environmental conditions. It is estimated that the average American drinks about one litre of water a day with 95% drinking less than three litres per day, for those working in a hot climate, up to 16 litres per day may be required. Some health authorities have suggested that at least eight glasses of eight fl oz each are required by an adult per day, the British Dietetic Association recommends 1.8 litres. However, various reviews of the evidence performed in 2002 and 2008 could not find any scientific evidence recommending eight glasses of water per day. An individuals thirst provides a guide for how much water they require rather than a specific

Rain
–
Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then precipitated—that is, become heavy enough to fall under gravity. Rain is a component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides suitable conditions for many types of ecosystems, as well as water for power plants. The major cause of production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds such as cumulonimbus which can organize into narrow rainbands. On the leeward side of mountains, desert climates can exist due to the dry air caused by downslope flow which causes heating and drying of the air mass, the movement of the monsoon trough, or intertropical convergence zone, brings rainy seasons to savannah climes. The urban heat island effect leads to increased rainfall, both in amounts and intensity, downwind of cities, global warming is also causing changes in the precipitation pattern globally, including wetter conditions across eastern North America and drier conditions in the tropics. The globally averaged annual precipitation over land is 715 mm, climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Rainfall is measured using rain gauges, rainfall amounts can be estimated by weather radar. Rain is also known or suspected on other planets, where it may be composed of methane, neon, sulfuric acid, or even iron rather than water. Air contains water vapor, and the amount of water in a mass of dry air. The amount of moisture in air is commonly reported as relative humidity. How much water vapor a parcel of air can contain before it becomes saturated, warmer air can contain more water vapor than cooler air before becoming saturated. Therefore, one way to saturate a parcel of air is to cool it, the dew point is the temperature to which a parcel must be cooled in order to become saturated. There are four mechanisms for cooling the air to its dew point, adiabatic cooling, conductive cooling, radiational cooling. Adiabatic cooling occurs when air rises and expands, the air can rise due to convection, large-scale atmospheric motions, or a physical barrier such as a mountain. Conductive cooling occurs when the air comes into contact with a surface, usually by being blown from one surface to another. Radiational cooling occurs due to the emission of infrared radiation, either by the air or by the surface underneath, evaporative cooling occurs when moisture is added to the air through evaporation, which forces the air temperature to cool to its wet-bulb temperature, or until it reaches saturation

Guano
–
Guano is the accumulated excrement of seabirds, seals, or cave-dwelling bats. As a manure, guano is an effective fertilizer due to its exceptionally high content of nitrogen, phosphate and potassium. During the twentieth century, guano-producing birds became an important target of conservation programs, today, guano is increasingly sought after by organic farmers. Seabird guano consists of nitrogen-rich ammonium oxalate and urate, phosphates, as well as some earth salts, the word guano originates from the Andean indigenous language Quechua, which refers to any form of dung used as an agricultural fertilizer. Archaeological evidence suggests that Andean people have collected guano from small islands, spanish colonial documents suggest that the rulers of the Inca Empire assigned great value to guano, restricted access to it, and punished any disturbance of the birds with death. The Guanay cormorant has historically been the most abundant and important producer of guano, other important guano producing species off the coast of Peru are the Peruvian pelican and the Peruvian booby. At that time, massive deposits of guano existed on some islands, in this context the United States passed the Guano Islands Act in 1856, which gave U. S. citizens discovering a source of guano on an unclaimed island exclusive rights to the deposits. Nine of these islands are still officially U. S. territories, control over guano played a central role in the Chincha Islands War between Spain and a Peruvian-Chilean alliance. Indentured workers from China played an important role in guano harvest, the first group of 79 Chinese workers arrived in Peru in 1849, by the time that trade ended a quarter of a century later, over 100,000 of their fellow countrymen had been imported. There is no evidence that enslaved Pacific Islanders participated in guano mining. Between 1847 and 1873, there was a significant increase in Peruvian guano exports, after 1870, the use of Peruvian guano as a fertilizer was eclipsed by saltpeter in the form of caliche extraction from the interior of the Atacama Desert, not far from the guano areas. Since 1909, when the Peruvian government took over guano extraction for use by Peru farmers, South Africa independently developed its own guano industry based on sustained-yield production from marine birds during this period, as well. Both industries eventually collapsed due to pressure from overfishing, DNA testing has suggested that new potato varieties imported alongside Peruvian seabird guano in 1842 brought a virulent strain of potato blight that began the Irish Potato Famine. The ideal type of guano is found in dry climates. Post-depositional decomposition and ammonia volatilization of penguin guano also plays an important role in the evolution of ornithogenic sediments in the cold, Bat guano is usually mined in caves and this mining is associated with a corresponding loss of troglobytic biota and diminishing of biodiversity. Guano deposits support a variety of cave-adapted invertebrates that rely on bat feces as their sole source of nutrition. The greatest damage caused by mining to caves with extant guano deposits is to the bat colonies themselves, bats are highly vulnerable to regular disturbance to their roosts. Some species, such as Phyllonycteris aphylla, have low fat reserves, many species will drop pups when in panic, with subsequent death, leading to a steady reduction in population

Ipomoea
–
Ipomoea is also a novel by John Rackham, published by Ace Books in 1969. Ipomoea is the largest genus in the plant family Convolvulaceae. It is a large and diverse group with common names including morning glory, water convolvulus or kangkung, sweet potato, bindweed, moonflower, the most widespread common name is morning glories, but there are also species in related genera bearing the same common name. Those formerly separated in Calonyction are called moonflowers, the generic name is derived from the Greek words ιπς or ιπος, meaning worm or bindweed, and όμοιος, meaning resembling. It refers to their twining habit, human use of Ipomoea include, Most species have spectacular, colorful flowers and are often grown as ornamentals, and a number of cultivars have been developed. Their deep flowers attract large Lepidoptera - especially Sphingidae such as the hawk moth - or even hummingbirds. The genus includes food crops, the tubers of sweet potatoes, the sweet potato is one of the Polynesian canoe plants, transplanted by settlers on islands throughout the Pacific. Other species are used on a scale, e. g. the whitestar potato traditionally eaten by some Native Americans, such as the Chiricahua Apaches. Peonidin, a potentially useful as a food additive, is present in significant quantities in the flowers of the Heavenly Blue cultivars. As early as 1600 BCE, the Olmecs produced the balls used in the Mesoamerican ballgame, the root called John the Conqueror in hoodoo and used in lucky and/or sexual charms usually seems to be from I. jalapa. The testicle-like dried tubers are carried as amulets and rubbed by the users to gain good luck in gambling or flirting, kiribadu Ala is one of the many ingredients of chyawanprash, the ancient Ayurvedic tonic called the elixir of life for its wide-ranging properties. The leaves of I. batatas are eaten as a vegetable, other species were and still are used as potent entheogens. Seeds of Mexican morning glory were thus used by Aztecs and Zapotecs in shamanistic and priestly divination rituals, ergoline derivatives are probably responsible for the entheogenic activity. Ergine, isoergine, D-lysergic acid N-amide and lysergol have been isolated from I. tricolor, alexander Shulgin in TiHKAL suggests ergonovine is responsible, instead. It has verified psychoactive properties, though as yet other undiscovered lysergamides possibly are present in the seeds, though most often noted as recreational drugs, the lysergamides are also of medical importance. Ergonovine enhances the action of oxytocin, used to still post partum bleeding, ergine induces drowsiness and a relaxed state and might be useful in treating anxiety disorder. Whether Ipomoea species are a source of these compounds remains to be determined. In any case, in some jurisdictions certain Ipomoea are regulated, many herbivores avoid morning glories such as Ipomoea, as the high alkaloid content makes these plants unpalatable, if not toxic

Heliotropium curassavicum
–
Heliotropium curassavicum is a species of heliotrope that is native to much of the Americas, from Canada to Argentina, and can be found on other continents as an introduced species. It thrives in salty soils, such as sand and alkali flats. This is a herb which can take the form of a prostrate creeper along the ground to a somewhat erect shrub approaching 0.5 m in height. The stem and foliage are fleshy, with the leaves thick, the plentiful inflorescences are curled, coiling double rows of small bell-shaped flowers. Each flower is white with five rounded lobes and a purple or yellow throat, the fruit is a smooth nutlet.

Portulaca oleracea
–
Portulaca oleracea is an annual succulent in the family Portulacaceae, which may reach 40 centimetres in height. Approximately forty cultivars are currently grown, scientists suggested that the plant was already eaten by native Americans, who spread its seeds. How it reached the New World is currently unknown and it is naturalised elsewhere, and in some regions is considered an introduced weed. It has smooth, reddish, mostly prostrate stems and alternate leaves clustered at stem joints, the yellow flowers have five regular parts and are up to 6 millimetres wide. Depending upon rainfall, the flowers appear at any time during the year, the flowers open singly at the center of the leaf cluster for only a few hours on sunny mornings. Seeds are formed in a pod, which opens when the seeds are mature. Purslane has a taproot with fibrous roots and is able to tolerate poor compacted soils. Widely used in East Mediterranean countries, archaeobotanical finds are common at prehistoric sites. In historic contexts, seeds have been retrieved from a layer in Kastanas, as well as from the Samian Heraion dating to seventh century BC. In the fourth century BC, Theophrastus names purslane, andrákhne, as Portulaca it figures in the long list of comestibles enjoyed by the Milanese given by Bonvesin de la Riva in his Marvels of Milan. In antiquity, its properties were thought so reliable that Pliny the Elder advised wearing the plant as an amulet to expel all evil. A common plant in parts of India, purslane is known as sanhti, punarva, paruppu keerai, gangabayala kura, although purslane is considered a weed in the United States, it may be eaten as a leaf vegetable. It has a sour and salty taste and is eaten throughout much of Europe, the Middle East, Asia. The stems, leaves and flower buds are all edible, purslane may be used fresh as a salad, stir-fried, or cooked as spinach is, and because of its mucilaginous quality it also is suitable for soups and stews. Australian Aborigines use the seeds of purslane to make seedcakes, greeks, who call it andrakla or glystrida, use the leaves and the stems with feta cheese, tomato, onion, garlic, oregano, and olive oil. They add it in salads, boil it, or add it to casseroled chicken, in Turkey, besides being used in salads and in baked pastries, it is cooked as a vegetable similar to spinach. Similarly, in Egypt, it is known as reglah رجلة, called Bakleh in Syria and Lebanon, is eaten raw in a famous salad called fattoush, and cooked as a garniture in fatayeh. In the south of Portugal, baldroegas are used as a soup ingredient, in Pakistan, it is known as qulfa and is cooked as in stews along with lentils, similarly to spinach, or in a mixed green stew

Grassland
–
Grasslands are areas where the vegetation is dominated by grasses, however sedge and rush families can also be found. Grasslands occur naturally on all continents except Antarctica, grasslands are found in most ecoregions of the Earth. For example, there are five terrestrial ecoregion classifications of the grasslands, savannas, and shrublands biome. Grassland vegetation can vary in height from short, as in chalk grassland, to quite tall, as in the case of North American tallgrass prairie, South American grasslands. Woody plants, shrubs or trees, may occur on some grasslands – forming savannas, scrubby grassland or semi-wooded grassland, as flowering plants and trees, grasses grow in great concentrations in climates where annual rainfall ranges between 500 and 900 mm. The root systems of perennial grasses and forbs form complex mats that hold the soil in place, graminoids are among the most versatile life forms. Existing forest biomes declined, and grasslands became much more widespread, following the Pleistocene ice ages, grasslands expanded in range in the hotter, drier climates, and began to become the dominant land feature worldwide. Grasslands often occur in areas with annual precipitation between 600 mm and 1,500 mm and average annual temperatures ranges from −5 and 20 °C. However, some occur in colder and hotter climatic conditions. Grassland can exist in habitats that are disturbed by grazing or fire. Grasslands dominated by unsown wild-plant communities can be called natural or semi-natural habitats. The majority of grasslands in temperate climates are semi-natural and these grasslands contain many species of wild plants – grasses, sedges, rushes and herbs –25 or more species per square metre is not unusual. Chalk downlands in England can support over 40 species per square metre, in many parts of the world, few examples have escaped agricultural improvement. For example, original North American prairie grasslands or lowland wildflower meadows in the UK are now rare and their associated wild flora equally threatened. Some of the worlds largest expanses of grassland are found in African savanna, grasslands may occur naturally or as the result of human activity. Grasslands created and maintained by human activity are called anthropogenic grasslands, hunting peoples around the world often set regular fires to maintain and extend grasslands, and prevent fire-intolerant trees and shrubs from taking hold. The tallgrass prairies in the U. S. Midwest may have been extended eastward into Illinois, Indiana, much grassland in northwest Europe developed after the Neolithic Period, when people gradually cleared the forest to create areas for raising their livestock.

Cenchrus echinatus
–
Cenchrus echinatus is a species of grass known by the common names southern sandbur, spiny sandbur, southern sandspur, and in Australia, Mossman River grass. It is native to North and South America and it is a clump-forming annual grass growing up to 80 cm tall. The leaves occur with or without hairs and measure up to 12 mm wide, the ligule is a fringe of hairs. The grass has barbed burrs up 4–10 mm long, in Australia it forms an invasive weed in coastal situations

Sida rhombifolia
–
Sida rhombifolia is a perennial or sometimes annual plant in the Family Malvaceae, native to the New World tropics and subtropics. Other common names include rhombus-leaved sida, Paddys lucerne, jelly leaf, and also somewhat confusingly as Cuban jute, Queensland-hemp and it is used in Ayurvedic medicine, where it is known as kurumthotti. This is another species, native to India, Sida cordifolia The stems are erect to sprawling and branched, growing 50 to 120 centimeters in height, with the lower sections being woody. The dark green, diamond-shaped leaves are arranged alternately along the stem,4 to 8 centimeters long and they are paler below, with short, grayish hairs. The apical half of the leaves have toothed or serrated margins while the remainder of the leaves are entire, the petioles have small spiny stipules at their bases. The moderately delicate flowers occur singly on flower stalks arise from the area between the stems and leaf petioles. They consist of five petals that are 4 to 8 millimeters long, creamy to orange-yellow in color, each of the five overlapping petals is asymmetric, having a long lobe on one side. The stamens unite in a short column, the fruit is a ribbed capsule, which breaks up into 8 to 10 segments. The plant blooms throughout the year and this species is usually confined to waste ground, such as roadsides and rocky areas, stock camps or rabbit warrens, but can be competitive in pasture, because of its unpalatability to livestock. The stems have a high quality fiber and were exported from India. However, it was reported that the root contained 450 ppm alkaloids, another source reports an alkaloid content in the root of 0.1 percent and the presence of choline, pseudoephedrine, beta-phenethylamine, vascin, hipaphorine and related indole alkaloids. Perhaps because of chemicals, arrowleaf sida is unpalatable to cattle. Arrowleaf sida has significant medicinal applications for which it is cultivated throughout India, the pounded leaves are used to relieve swelling, the fruits are used to relieve headache, the mucilage is used as an emollient, and the root is used to treat rheumatism. Australian Aborigines use the herb to treat diarrhea, leaves are smoked in Mexico and a tea is prepared in India for the stimulation it provides. In Alor, Eastern Indonesia the leaves are used to treat boils, wildflowers of Houston & Southeast Texas.

Phyllanthus
–
Phyllanthus is the largest genus in the flowering plant family Phyllanthaceae. Estimates of the species in this genus vary widely, from 750 to 1200. Phyllanthus has a diversity of growth forms including annual and perennial herbs, shrubs, climbers, floating aquatics. Some have flattened leaflike stems called cladodes and it has a wide variety of floral morphologies and chromosome numbers and has one of the widest range of pollen types of any seed plant genus. Despite their variety, almost all Phyllanthus species express a type of growth called phyllanthoid branching in which the vertical stems bear deciduous, floriferous. The leaves on the axes are reduced to scales called cataphylls. Phyllanthus is distributed in all tropical and subtropical regions on Earth, leafflower is the common name for all Phyllanthus species. The circumscription of this genus has been a cause of much confusion, Molecular phylogenetic studies have shown that Phyllanthus is paraphyletic over Reverchonia, Glochidion, Sauropus, and Breynia. A recent revision of the family Phyllanthaceae has subsumed all four of these genera into Phyllanthus and this enlarged version of Phyllanthus might eventually be divided into smaller genera, but much more research will be needed before anyone knows how to do this. Progress continues to be made in this area, also see Taxonomy of the Phyllanthaceae and Phyllanthaceae.

Solanum
–
If used for a particular species, this name usually applies to the Carolina horsenettle. Solanum is a large and diverse genus of flowering plants, which include two food crops of economic importance, the potato and the tomato. It also contains the nightshades and horse nettles, as well as numerous plants cultivated for their ornamental flowers, Solanum species show a wide range of growing habits, such as annual and perennials, vines, subshrubs, shrubs, and small trees. Many formerly independent genera like Lycopersicon and Cyphomandra are now included in Solanum as subgenera or sections, thus, the genus today contains roughly 1, 500–2,000 species. The generic name was first used by Pliny the Elder for a plant also known as strychnos and its derivation is uncertain, possibly stemming from the Latin word sol, meaning sun, referring to its status as a plant of the sun. Another possibility is that the root was solare, meaning to soothe, or solamen, meaning a comfort, the species most commonly called nightshade in North America and Britain is Solanum dulcamara, also called bittersweet or woody nightshade. Its foliage and egg-shaped red berries are poisonous, the principle being solanine. The black nightshade is also generally considered poisonous, but its fully ripened fruit and foliage are cooked, the deadly nightshade is not in the Solanum genus, but is a member of the wider Solanaceae family. Most parts of the plants, especially the parts and unripe fruit, are poisonous to humans. However, several species are used in folk medicine, particularly by native peoples who have long employed them. Solanum species are used as food plants by the larvae of some Lepidoptera species – see list of Lepidoptera that feed on Solanum, the genus was established by Carl Linnaeus in 1753. Its subdivision has always been problematic, but slowly some sort of consensus is being achieved, the following list is a provisional lineup of the genus traditional subdivisions, together with some notable species. Many of the subgenera and sections might not be valid, they are used here provisionally as the phylogeny of this genus is not fully resolved yet, cladistic analyses of DNA sequence data suggests that the present subdivisions and rankings are largely invalid. Far more subgenera would seem to warrant recognition, with Leptostemonum being the one that can at present be clearly subdivided into sections. Notably, it includes as a major lineage several members of the traditional sections Cyphomandropsis, Section Allophylla Solanum granuloso-leprosum Section Cyphomandropsis Solanum glaucophyllum Desf. – Waxy-leaved nightshade Section Pachyphylla Solanum betaceum Cav, – Tamarillo Solanum exiguum Solanum roseum Section Acanthophora Solanum aculeatissimum Jacq.

Brassica juncea
–
Brassica juncea, mustard greens, leaf mustard, Indian mustard, Chinese mustard, jie cai or kai choi is a species of mustard plant. One subvariety is southern giant curled mustard, which resembles a headless cabbage such as kale and it is also known as green mustard cabbage. The leaves, seeds, and stems of this variety are edible. The plant appears in form in African, Pakistani, Bangladeshi, Italian, Indian, Chinese, Japanese, Korean. Cultivars of B. juncea are grown for their greens, the mustard condiment made from the seeds of the B. juncea is called brown mustard and is considered to be spicier than yellow mustard. Because it may contain erucic acid, a toxin, mustard oil is restricted from import as a vegetable oil into the United States. Essential oil of mustard, however, is accepted as GRAS, but in Russia, this is the main species grown for the production of mustard oil. It is widely used in canning, baking and margarine production in Russia, tatsai, which has a particularly thick stem, is used to make the Indian pickle called achar, and the Chinese pickle zha cai. The Gorkhas of Darjeeling and Sikkim prepare pork with mustard greens and it is usually eaten with relish and steamed rice, but can also be eaten with chapati. Brassica juncea is more pungent than greens from the closely related Brassica oleracea, Chinese and Japanese cuisines also make use of mustard greens. In Japanese cuisine, it is known as takana and often pickled for use as filling in onigiri or as a condiment, many varieties of B. juncea cultivars are used, including zha cai, mizuna, takana, juk gai choy, and xuelihong. Asian mustard greens are most often stir-fried or pickled, a Southeast Asian dish called asam gai choy or kiam chai boey is often made with leftovers from a large meal. It involves stewing mustard greens with tamarind, dried chillies and leftover meat on the bone, Brassica juncea is also known as gai choi, siu gai choi, xaio jie cai, baby mustard, Chinese leaf mustard or mostaza. In 100 grams, cooked mustard greens provide 26 calories and are a source of vitamins A, C and K which is especially high as a multiple of its Daily Value. Mustard greens are a source of vitamin E and calcium. Greens are 92% water,4. 5% carbohydrates,2. 6% protein and 0. 5% fat, vegetable growers sometimes grow mustard as a green manure. Its main purpose is to act as a mulch, covering the soil to suppress weeds between crops, in the UK, mustard sown in summer and autumn is cut down starting in October. April sowings can be cut down in June, keeping the ground clear for summer-sown crops, one of the disadvantages of using mustard as a green manure is its propensity to harbor club root

Brown booby
–
The brown booby is a large seabird of the booby family, Sulidae. The female booby reaches about 80 centimetres in length, its wingspan measures up to 150 cm, the male booby reaches about 75 centimetres in length, its wingspan measures up to 140 cm, and they can weigh up to 1,000 g. The boobys head and upper body is covered in brown or black. The juvenile form is gray-brown with darkening on the head, wings, while these birds are typically silent, bird watchers have reported occasional sounds similar to grunting or quacking. Their beaks are quite sharp and contain many jagged edges and they have short wings and long, tapered tails. This species breeds on islands and coasts in the pan tropical areas of the Atlantic and Pacific oceans and they frequent the breeding grounds of the islands in the Gulf of Mexico and the Caribbean Sea. This bird nests in colonies, laying two chalky blue eggs on the ground in a mound of broken shells and vegetation. It winters at sea over a wider area, brown booby pairs may remain together over several seasons. They perform elaborate greeting rituals, and are also spectacular divers and they mainly eat small fish or squid which gather in groups near the surface and may catch leaping fish while skimming the surface. Although they are powerful and agile fliers, they are clumsy in takeoffs and landings, they use strong winds. The four subspecies recognised are, Sula leucogaster brewsteri Goss 1888 Sula leucogaster etesiaca Thayer & Bangs 1905 Sula leucogaster leucogaster 1783 Sula leucogaster plotus 1844 Harrison, the Audubon Society Field Guide to North American Birds, Eastern Region.

White tern
–
The white tern is a small seabird found across the tropical oceans of the world. It is sometimes known as the fairy tern although this name is confusing as it is the common name of the fairy tern Sternula nereis. Other names for the species include angel tern and white noddy, the white tern has 3–4 subspecies, the nominate race G. a. alba, G. a. leucopes, the Pacific white tern. Additionally, the white tern was long and often is still included herein as a subspecies G. a. microrhyncha. G. a. alba, tropical islands of the south Atlantic G. a. candida, Seychelles & Mascarene Islands to central Pacific including southern Maldives excluding ranges of next two ssp. G. a. microrhyncha, Phoenix, Line and Marquesas Islands G. a. leucopes, Pitcairn Islands Related to the noddies, the tern is small with white plumage. With a wingspan of about 25 inches, it widely across the Pacific and Indian Oceans. Nesting on coral islands, usually on trees with branches but also on rocky ledges and on man-made structures. This tern lives in Oceania, from Hawaii to New Zealand, along the coast of China and Vietnam, Indonesia, India, rarely it is also found in Japan, Madagascar, Mexico, and on some islands in the Atlantic Ocean. It is a pelagic and epipelagic bird, living along the coast and this small tern is notable for laying its egg on bare thin branches in a small fork or depression without a nest. This behaviour is unusual for terns, which generally nest on the ground and it is thought that the reason for the absence of nests is the reduction in nest parasites, which in some colonial seabirds can cause the abandonment of an entire colony. In spite of these there are costs associated with tree nesting, as the eggs. For this reason the white tern is also quick to relay should it lose the egg, the newly hatched chicks have well developed feet with which to hang on to their precarious nesting site. It is a bird, having been recorded living for 42 years. The white tern is not considered threatened as it is a species with several large colonies around the world. The white tern, manu-o-Kū, was named Honolulu, Hawaiʻis official bird on April 2,2007, white tern videos, photos & sounds on the Internet Bird Collection
