Potamidae
Potamidae is a family of freshwater crabs. It includes more than 650 species and nearly 100 genera, which are placed into two subfamilies: Potaminae and Potamiscinae. Subfamily Potaminae The Potaminae Ortmann, 1896 are distributed around the Mediterranean Sea, on Socotra and eastwards to Northern India. *'' Acanthopotamon'' Kemp, 1918 *'' Alcomon'' Yeo & Ng, 2007 *'' Himalayapotamon'' Pretzmann, 1966 *'' Lobothelphusa'' Bouvier, 1917 *'' Paratelphusula'' Alcock, 1909 *''Potamon'' Savigny, 1816 *''Socotra'' Cumberlidge & Wranik, 2002 *'' Socotrapotamon'' Apel & Brandis, 2000 Subfamily Potamiscinae The Potamiscinae Bott, 1970 are found in East Asia and Southeast Asia. *'' Acartiapotamon'' Dai, 1999 *'' Allopotamon'' Ng, 1988 *'' Amamiku'' Naruse, Segawa & Shokita, 2004 *'' Aparapotamon'' Dai & G.

IUCN Red List Of Threatened Species
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 International Union for Conservation of Nature, 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.

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Crab
Around 1,300 species of freshwater crabs are distributed throughout the tropics and subtropics, divided among eight families. They show direct development and maternal care of a small number of offspring, in contrast to marine crabs, which release thousands of planktonic larvae. This limits the dispersal abilities of freshwater crabs, so they tend to be endemic to small areas. As a result, a large proportion are threatened with extinction. Systematics More than 1,300 described species of freshwater crabs are known, out of a total of 6,700 species of crabs across all environments. The total number of species of freshwater crabs, including undescribed species, is thought to be up to 65% higher, potentially up to 2,155 species, although most of the additional species are currently unknown to science. They belong to eight families, each with a limited distribution, although various crabs from other families are also able to tolerate freshwater conditions ( euryhaline) or are second ...

Yanyuan County
Yanyuan County (; ii, ꋂꂿꑤ ce mo xiep) is a county in Liangshan Prefecture, Sichuan Province, China, bordering Yunnan province to the west. The county is located in Sichuan's rugged Hengduan Mountains in southwest Sichuan, but the county seat of Yanjing () is situated in an unusually flat basin with a diameter. Yanjing, as the county seat, is usually referred to as Yanyuan. History Yanyuan County was originally inhabited by the Yi people, but has since been incorporated into Han Chinese culture. The region has long been a source of salt for the Chinese and the name Yanyuan () literally means "Salt source". Until recently, Yanyuan was poorly connected with the rest of China by road. In the 2010s, a new tunnel was built through the mountains east of Yanyuan to connect the county with the prefecture capital of Xichang. Geography In the west, Yanyuan County encompasses the eastern shores of Lugu Lake, shared with Yunnan Province. To the north and east, Yanyuan is bord ...

Crustaceans Described In 1990
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by their l ...

Monotypic Decapod Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...
