Odontonema Brevipes
''Odontonema brevipes'' is a species of plant in the family Acanthaceae which is endemic to Trinidad and Tobago. The species is only known from four localities in the Main Ridge of Tobago. It was described by German botanist Ignatz Urban in his ''Symbolae Antillanae'', based on collections made by Danish botanist Henrik von Eggers and English-born Trinidadian botanist Walter Elias Broadway. Conservation status Although ''Odontonema brevipes'' is not listed in the IUCN Red List, the authors of a 2008 assessment of the endemic plant species of Trinidad and Tobago considered it vulnerable Vulnerable may refer to: General * Vulnerability * Vulnerability (computing) * Vulnerable adult * Vulnerable species Music Albums * ''Vulnerable'' (Marvin Gaye album), 1997 * ''Vulnerable'' (Tricky album), 2003 * ''Vulnerable'' (The Used album) ... due to the fact that it is known from a restricted area or small number of localities.

Ignatz Urban
Ignatz Urban (7 January 1848 – 7 January 1931) was a German botanist. He is known for his contributions to the flora of the Caribbean and Brazil, and for his work as curator of the Berlin Botanical Garden. Born the son of a brewer, Urban showed an interest in botany as an undergraduate. He pursued further study at the University of Bonn and later at the University of Berlin where he gained a doctorate in 1873. Urban was appointed by A. W. Eichler to run the Berlin Botanical Garden and supervised its move to Dahlem. He also worked as Eichler's assistant on the ''Flora Brasiliensis'', later succeeding him as editor. In 1884 Urban began working with Leopold Krug on his Puerto Rican collections, a collaboration would later produce the nine-volume '' Symbolae Antillanae'', one of his most important contributions, and his 30-part ''Sertum Antillanum''. Urban's herbarium, estimated to include 80,000 or more sheets, was destroyed when the Berlin Herbarium was bombed in 1943 ...

Acanthaceae
Acanthaceae is a family (the acanthus family) of dicotyledonous flowering plants containing almost 250 genera and about 2500 species. Most are tropical herbs, shrubs, or twining vines; some are epiphytes. Only a few species are distributed in temperate regions. The four main centres of distribution are Indonesia and Malaysia, Africa, Brazil, and Central America. Representatives of the family can be found in nearly every habitat, including dense or open forests, scrublands, wet fields and valleys, sea coast and marine areas, swamps, and mangrove forests. Description Plants in this family have simple, opposite, decussated leaves with entire (or sometimes toothed, lobed, or spiny) margins, and without stipules. The leaves may contain cystoliths, calcium carbonate concretions, seen as streaks on the surface. The flowers are perfect, zygomorphic to nearly actinomorphic, and arranged in an inflorescence that is either a spike, raceme, or cyme. Typically, a colorful bract subtends ea ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trinidad And Tobago
Trinidad and Tobago (, ), officially the Republic of Trinidad and Tobago, is the southernmost island country in the Caribbean. Consisting of the main islands Trinidad and Tobago, and numerous much smaller islands, it is situated south of Grenada and off the coast of northeastern Venezuela. It shares maritime boundaries with Barbados to the northeast, Grenada to the northwest and Venezuela to the south and west. Trinidad and Tobago is generally considered to be part of the West Indies. The island country's capital is Port of Spain, while its largest and most populous city is San Fernando. The island of Trinidad was inhabited for centuries by Indigenous peoples before becoming a colony in the Spanish Empire, following the arrival of Christopher Columbus, in 1498. Spanish governor José María Chacón surrendered the island to a British fleet under the command of Sir Ralph Abercromby in 1797. Trinidad and Tobago were ceded to Britain in 1802 under the Treaty of Amiens as se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Ridge, Tobago
Main Ridge is the main mountainous ridge on the island of Tobago, Trinidad and Tobago. It is a chain of hills which runs from southwest to northeast between the Caribbean Sea and the Southern Tobago fault system and reaches a maximum height of . The Main Ridge Forest Reserve, which was legally established in 1776, is one of the oldest protected areas in the world. It is a popular site for birdwatching and ecotourism. Main Ridge provides important habitat for native plants and animals, including several species endemic to Tobago. History The Treaty of Paris in 1763 ended Tobago's status as a neutral territory and made it a British colony. The Treaty of Aix-la-Chappelle in 1748 had designated Tobago neutral territory and left it in the hands of its remaining indigenous population, but the return to British control led to a rapid conversion of the island to a plantation economy. Under the direction of the Board of Trade, the island was surveyed, divided into plots, and sold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tobago
Tobago () is an List of islands of Trinidad and Tobago, island and Regions and municipalities of Trinidad and Tobago, ward within the Trinidad and Tobago, Republic of Trinidad and Tobago. It is located northeast of the larger island of Trinidad and about off the northeastern coast of Venezuela. It also lies to the southeast of Grenada. The official bird of Tobago is the cocrico. Etymology Tobago was named ''Belaforme'' by Christopher Columbus "because from a distance it seemed beautiful". The Spanish friar Antonio Vázquez de Espinosa wrote that the Kalina people, Kalina (mainland Caribs) called the island ''Urupina'' because of its resemblance to a big snail, while the Island Caribs, Kalinago (Island Caribs) called it ''Aloubaéra'', supposedly because it resembled the ''alloüebéra'', a giant snake which was supposed to live in a cave on the island of Dominica. The earliest known record of the use of the name ''Tabaco'' to refer to the island is a Spanish royal order is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Endemic Flora Of Trinidad And Tobago
The endemic flora of Trinidad and Tobago includes a total of 59 species of vascular plants belonging to 34 plant families. This is less than 3% of the total vascular plant flora of Trinidad and Tobago. Thirty-nine of these species are endemic to Trinidad, 12 are Tobagonian endemics, and six are present on both islands. Island systems tend to be rich centres of endemism as a result of their isolation. The islands of the Greater Antilles have rates of endemism which range from 12-50% of their flora. Trinidad and Tobago has a far lower rate of endemism, probably as a result of its geological history. The islands of Trinidad and Tobago lie on the South American continental shelf, and were both connected to the mainland during the Pleistocene. Tobago was separated from the mainland about 13,000 years ago; Trinidad was connected until more recently, and may only have become separated about 1,500 years ago. The flora of Trinidad and Tobago has been estimated to include about 2,50 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
