Hynobius Turkestanicus
The Turkestanian salamander (''Hynobius turkestanicus'') is a species of salamander in the family 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. ... only once found in 1909 (4 animals) in Central Asia somewhere "in Turkestan between Samarkand and Pamir" which can be in Tajikistan, Uzbekistan or Kyrgyzstan. Since then the species has not been seen in the wild. None remain in captivity. The Turkestanian salamander is currently on the list of the 10 Most Wanted Amphibians, a rediscovery effort launched by Conservation International.

Alexander Mikhailovich Nikolsky
Alexander Mikhailovich Nikolsky (Russian: Александр Михайлович Никольский; February 18, 1858 – December 8, 1942) was a Russian and Ukrainian zoologist born in Astrakhan. From 1877 to 1881, he studied at the University of St. Petersburg, earning his doctorate several years later in 1887. From 1881 to 1891, he took part in numerous expeditions to Siberia, the Caucasus, Persia, Japan, et al. In 1887 he became an associate professor in St. Petersburg, later becoming director of the herpetology department at the Zoological Museum of the Academy of Sciences (1895). In 1903 he relocated as a professor to the Kharkiv University. In 1919 he was elected a member at the Academy of Sciences of Ukraine. Among his written works were ''Herpetologia Caucasica'' (1913), and volumes on reptiles and amphibians that were part of the series "Fauna of Russia and Adjacent Countries". He is the taxonomic authority of 26 reptile species. The viper '' Vipera nikolski ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Asiatic Salamander
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.

Conservation International
Conservation International (CI) is an American nonprofit environmental organization headquartered in Crystal City, Arlington, Virginia. CI's work focuses on science, policy and partnership with businesses, governments and communities. The organization employs nearly 1,000 people and works with more than 2,000 partners in 29 countries. CI has helped support 1,200 protected areas and interventions across 77 countries, protecting more than 6 million square kilometers (2.3 million square miles) of land and sea. History Conservation International was founded in 1987 with the goal of protecting nature for the benefit of people. In 1989, CI formally committed to the protection of biodiversity hotspots, ultimately identifying 36 such hotspots around the world and contributing to their protection. The model of protecting hotspots became a key way for organizations to do conservation work. On July 1, 2017, Peter Seligmann stepped down as CEO of CI and a new executive team made up o ...

Amphibians Described In 1909
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...

Taxa Named By Alexander Nikolsky
In biology, a taxon (back-formation from ''Taxonomy (biology), taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular Taxonomic rank, ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of bio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
