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] |

Nominate Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lumpers And Splitters
Lumpers and splitters are opposing factions in any discipline that has to place individual examples into rigorously defined categories. The lumper–splitter problem occurs when there is the desire to create classifications and assign examples to them, for example schools of literature, biological taxa and so on. A "lumper" is a person who assigns examples broadly, assuming that differences are not as important as signature similarities. A "splitter" is one who makes precise definitions, and creates new categories to classify samples that differ in key ways. Origin of the terms The earliest known use of these terms was by Charles Darwin, in a letter to Joseph Dalton Hooker in 1857: ''It is good to have hair-splitters & lumpers''. They were introduced more widely by George G. Simpson in his 1945 work ''The Principles of Classification and a Classification of Mammals''. As he put it: A later use can be found in the title of a 1969 paper "On lumpers and splitters ..." by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korrigum
The korrigum (''Damaliscus lunatus korrigum''), also known as Senegal hartebeest, is a subspecies of the Damaliscus lunatus, topi, a large African antelope. Taxonomy An 1822–1824 British expedition across the Sahara to the ancient kingdom of Kanem–Bornu Empire#Successors, Bornu, returned with single set of horns of an antelope known in the language of that land as a ''korrigum''. These horns were classified as a new species by William Ogilby in an article in the journal ''Proceedings of the Zoological Society of London'' dated 1836, but published in 1837. Description Korrigan were said to differ from the tiang subspecies based on the tail tuft being more bushy, and the pelage being more reddish. In the tiang, the patches of dark hair on the legs were said to be somewhat larger. In the Belgian Congo, a topi was shot in the 19th century which is intermediate between these two. Morphometrically, korrigan and tiang were found to be indistinguishable. Range and conservation Ko ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kanem–Bornu Empire
The Kanem–Bornu Empire existed in areas which are now part of Nigeria, Niger, Cameroon and Chad. It was known to the Arabian geographers as the Kanem Empire from the 8th century AD onward and lasted as the independent kingdom of Bornu (the Bornu Empire) until 1900. The Kanem Empire (c. 700–1380) was located in the present countries of Chad, Nigeria and Libya. At its height, it encompassed an area covering not only most of Chad but also parts of southern Libya (Fezzan) and eastern Niger, northeastern Nigeria and northern Cameroon. The Bornu Empire (1380s–1893) was a state in what is now northeastern Nigeria, in time becoming even larger than Kanem, incorporating areas that are today parts of Chad, Niger, Sudan, and Cameroon. The early history of the empire is mainly known from the Royal Chronicle, or '' Girgam'', discovered in 1851 by the German traveller Heinrich Barth. Remnant successor regimes of the empire, in form of the Borno Emirate and Dikwa Emirate, were establis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Le Règne Animal
''Le Règne Animal'' (The Animal Kingdom) is the most famous work of the French naturalist Georges Cuvier. It sets out to describe the natural structure of the whole of the animal kingdom based on comparative anatomy, and its natural history. Cuvier divided the animals into four ''embranchements'' ("Branches", roughly corresponding to phyla), namely vertebrates, molluscs, articulated animals (arthropods and annelids), and zoophytes (cnidaria and other phyla). The work appeared in four octavo volumes in December 1816 (although it has "1817" on the title pages); a second edition in five volumes was brought out in 1829–1830 and a third, written by twelve "disciples" of Cuvier, in 1836–1849. In this classic work, Cuvier presented the results of his life's research into the structure of living and fossil animals. With the exception of the section on insects, in which he was assisted by his friend Pierre André Latreille, the whole of the work was his own. It was translated into ...

George Cuvier
Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French naturalist and zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastrophic flooding events. In this way, ...

Ruminant
Ruminants (suborder Ruminantia) are ungulate, hoofed herbivorous grazing or browsing mammals that are able to acquire nutrients from plant-based food by Enteric fermentation, fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The process, which takes place in the front part of the digestive system and therefore is called foregut fermentation, typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again. The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination. The word "ruminant" comes from the Latin ''ruminare'', which means "to chew over again". The roughly 200 species of ruminants include both domestic and wild species. Ruminating mammals include cattle, all domesticated and wild bovines, goats, sheep, giraffes, deer, gazelles, and antelopes.Fowler, M.E.

Charles Hamilton Smith
Lieutenant-Colonel Charles Hamilton Smith, KH, KW, FRS, FLS, (26 December 1776 in East Flanders, in the United Provinces of the Netherlands – 21 September 1859 in Plymouth) was an English artist, naturalist, antiquary, illustrator, soldier, and spy. Military service His military career began in 1787, when he studied at the Austrian academy for artillery and engineers at Mechelen and Leuven in Belgium. Although his military service, which ended in 1820 and included the Napoleonic Wars, had him travel extensively (including the West Indies, Canada, and United States), much of his time was spent at a desk job in Britain. One of his noteworthy achievements was an 1800 experiment to determine which colour should be used for military uniforms. The increasing accuracy of firearms, especially rifles, brought advantages to shades which offer a less distinctive target – by testing the accuracy of a rifle company against grey, green, and red targets, he showed scientifically the a ...
