Anabarilius Liui Liui
''Anabarilius liui'' is a species of ray-finned fish in the genus ''Anabarilius''. The nominate subspecies ''lui'' is endemic to the upper Yangtze basin in China, but there are no recent records and it is considered extinct in the 2009 Chinese 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 biologi ....Wang, S.; and Xie, Y.

Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinopt ...

Anabarilius
''Anabarilius'' is a genus of ray-finned fish in the family Cyprinidae, most of them only occurring in China. Many of the species have very restricted geographic range and have been negatively impacted by introduced species, fishing, and habitat degradation; the IUCN Red List includes five ''Anabarilius'' species that are either endangered or critically endangered and one species ('' A. macrolepis'') that is considered extinct. Species The genus contains the following species: * ''Anabarilius alburnops'' (Regan, 1914) * '' Anabarilius andersoni'' (Regan, 1904) * '' Anabarilius brevianalis'' W. Zhou & G. H. Cui, 1992 * '' Anabarilius duoyiheensis'' W. X. Li, W. N. Mao & Zong-Min Lu, 2002 * '' Anabarilius goldenlineus'' W. X. Li & A. L. Chen, 1995 * ''Anabarilius grahami'' (Regan, 1908) * '' Anabarilius liui'' (H. W. Chang, 1944) * '' Anabarilius longicaudatus'' Y. R. Chen, 1986 * †''Anabarilius macrolepis'' P. L. Yih & C. K.

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] |
Yangtze
The Yangtze or Yangzi ( or ; ) is the longest river in Asia, the third-longest in the world, and the longest in the world to flow entirely within one country. It rises at Jari Hill in the Tanggula Mountains (Tibetan Plateau) and flows in a generally easterly direction to the East China Sea. It is the seventh-largest river by discharge volume in the world. Its drainage basin comprises one-fifth of the land area of China, and is home to nearly one-third of the country's population. The Yangtze has played a major role in the history, culture, and economy of China. For thousands of years, the river has been used for water, irrigation, sanitation, transportation, industry, boundary-marking, and war. The prosperous Yangtze Delta generates as much as 20% of historical GDP of China, China's GDP. The Three Gorges Dam on the Yangtze is the list of the largest hydroelectric power stations, largest hydro-electric power station in the world that is in use. In mid-2014, the Chine ...

Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regional Red List
A Regional Red List is a report of the threatened status of species within a certain country or region. It is based on the IUCN Red List of Threatened Species, an inventory of the conservation status of species on a global scale. Regional Red Lists assess the risk of extinction to species within a political management unit and therefore may feed directly into national and regional planning. This project is coordinated by the Zoological Society of London, the World Conservation Union (IUCN) and partners in national governments, universities and organizations throughout the world. Regional Red Lists may assist countries or regions in: * Determining the conservation status and trends of species * Identifying species or ecosystems under greatest threat * Informing conservation planning and priority setting * Raising awareness of threatened species Assessing extinction risk on a regional scale The IUCN Categories and Criteria were initially designed to assess the conservation s ...
