Ranodon
''Ranodon'' is a monotypic genus of salamanders in the family Hynobiidae. It currently contains only one species, the Central Asian salamander (''Ranodon sibiricus''). Formerly in this genus were: * Wushan salamander (''Liua shihi'') * Tsinpa salamander (''Liua tsinpaensis'') * Yellow-spotted salamander (''Pseudohynobius flavomaculatus'') Distribution The Central Asian salamander is found in the Dzungarian Alatau mountains on the border of China China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and ... and Kazakhstan. Its natural habitat is temperate forest, tundra, temperate grassland, rivers, and freshwater marshes, and springs. The species is threatened by habitat loss.

Hynobiidae
The Asiatic salamanders (family Hynobiidae) are primitive salamanders found all over Asia, and in European Russia. They are closely related to the giant salamanders (family Cryptobranchidae), with which they form the suborder Cryptobranchoidea. About half of hynobiids currently described are endemic to Japan. Hynobiid salamanders practice external fertilization, or spawning. And, unlike other salamander families which reproduce internally, male hynobiids focus on egg sacs rather than females during breeding. The female lays two egg sacs at a time, each containing up to 70 eggs. Parental care is common. A few species have very reduced lungs, or no lungs at all. Larvae can sometimes have reduced external gills if they live in cold and very oxygen-rich water. Fossils of hynobiids are known from the Miocene to the present in Asia and Eastern Europe, though fossils of Cryptobranchoids more closely related to hynobiids than to giant salamanders extend back to the Middle Jurassic.

Yellow-spotted Salamander
The yellow-spotted salamander (''Pseudohynobius flavomaculatus'') is a species of salamander in the family Hynobiidae, endemic to China, where it is known from Nanchuan in Chongqing (formerly Sichuan), Suiyang in Guizhou, Lichuan in Hubei, and Sangzhi in Hunan Province. However, genetic methods have revealed cryptic species within the ''Liua''–''Pseudohynobius ''Pseudohynobius'' is a genus of salamanders in the family Hynobiidae The Asiatic salamanders (family Hynobiidae) are primitive salamanders found all over Asia, and in European Russia.

The 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 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 provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Karl Fedorovich Kessler
Karl Fedorovich Kessler (19 November 1815 – 3 March 1881) was a German-Russian zoologist and author of zoological taxa signed ''Kessler'', who was mostly active in Kyiv, Ukraine. He conducted most of his studies of birds in Ukrainian regions of the Russian Empire: Kiev Governorate, Volyn Governorate, Kherson Governorate, Poltava Governorate and Bessarabia. He also studied the fish of the Dniester, Dnieper, and Southern Bug rivers, and on the Ukrainian coast of the Black Sea. Kessler was one of the first zoologists to propose that mutual aid, rather than mutual struggle, was the main factor in the evolution of a species. The anarchist Peter Kropotkin later developed this theory in his book '' Mutual Aid: A Factor of Evolution''. Tribute The Kessler's gudgeon ''(Romanogobio kesslerii)'' was named after him.

Monotypic
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.' ...

Salamander
Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela. Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders rarely have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs. Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. Some salamander species are fully aquatic throughout their lives, some take to the water intermittently, and others are entirely terrestrial as adults. This group of amphibians is capable of regenerating lost l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
