Triplophysa Alticeps
''Triplophysa alticeps'' is a species of ray-finned fish in the genus ''Triplophysa''. These Nemacheilidae, stone loaches are occasionally placed in the genus ''Qinghaichthys'' by some authorities.Kottelat, M.

Solomon Markovitch Herzenstein
Solomon Markovich Herzenstein (; 1854 – August 7, 1894) was a Russian zoologist. Biography Herzenstein received a degree in natural sciences and mathematics from St. Petersburg University and was appointed as the custodian of the Zoological Museum of the Imperial Academy of Science in 1879 or 1880. He also supervised practical training at the University for Women. In 1880, 1884, and 1887, he was commissioned to travel to the Murman Coast of the Kola Peninsula to study the mollusks and fishes there. His work, "Materialy k Faunye Murmanskavo Berega i Byelavo Morya," which was published in the ''Trudy'' of the in 1885, became a standard reference. He co-wrote ''Zamyetki po Ikhtologii Basseina Ryeki Amura'' (1887) and ''Nauchnye Rezultaty Puteshestvi Przevalskavo'' (1888–91) with N. L. Varpakhovski. He also wrote ''Ryby'' (St. Petersburg, 1888-91), and published "Ichthyologische Bemerkungen" in the ' (1890-92). Species described * '' Acanthogobio guentheri'' (Herzenstein, ...

Ray-finned Fish
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 Actinoptery ...

Triplophysa
''Triplophysa'' is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera (''Hedinichthys'', ''Indotriplophysa'', ''Labiatophysa'', ''Qinghaichthys'' and ''Tarimichthys''), but as Wikipedia follows Fishbase for fish species all but ''Hedinichthys'' have been treated as subgenera in Wikipedia, although Kottelat in his revision of the loaches did recognise them as valid. FishBase, however, includes these in ''Triplophysa'' without specifying subgenera and treats the names given by Kottelat as synonyms. Ecology ''Triplophysa zhaoi'' holds the record for the lowest altitude for Asian fish: it is found at below sea level in swamps of the Lükqün oasis, in the Turpan Depression in Xinjiang. In the other end, ''Triplophysa stolickai'' holds the record altitude for Asian fish: it is found at above sea level in hot sprin ...

Nemacheilidae
The Nemacheilidae, or stone loaches, are a family of cypriniform fishes that inhabit stream environments, mostly in Eurasia, with one genus, ''Afronemacheilus'' found in Africa Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area .... The family includes about 790 species. Genera The following are the described genera of the family: References Taxa named by Charles Tate Regan {{Nemacheilidae-stub ...

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] |
Qinghaihu Lake
Qinghai Lake or Ch'inghai Lake, also known by other names, is the largest lake in China. Located in an endorheic basin in Qinghai Province, to which it gave its name, Qinghai Lake is classified as an alkaline salt lake. The lake has fluctuated in size, shrinking over much of the 20th century but increasing since 2004. It had a surface area of , an average depth of , and a maximum depth of in 2008. Names Qinghai is the romanized Standard Chinese pinyin pronunciation of the name Although modern Chinese distinguishes between the colors blue and green, this distinction did not exist in classical Chinese. The color (''qīng'') was a "single" color inclusive of both blue and green as separate shades. (English for ''qīng'' is cyan or turquoise, also linguists have coined the portmanteau "grue" to discuss its existence in Chinese and other languages.) The name is thus variously translated as "Blue Sea", "Green Sea", "Blue-Green Sea", "Blue/Green Sea", etc. For a time af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qinghai
Qinghai (; alternately romanized as Tsinghai, Ch'inghai), also known as Kokonor, is a landlocked province in the northwest of the People's Republic of China. It is the fourth largest province of China by area and has the third smallest population. Its capital and largest city is Xining. Qinghai borders Gansu on the northeast, Xinjiang on the northwest, Sichuan on the southeast and the Tibet Autonomous Region on the southwest. Qinghai province was established in 1928 during the period of the Republic of China, and until 1949 was ruled by Chinese Muslim warlords known as the Ma clique. The Chinese name "Qinghai" is after Qinghai Lake, the largest lake in China. The lake is known as Tso ngon in Tibetan, and as Kokonor Lake in English, derived from the Mongol Oirat name for Qinghai Lake. Both Tso ngon and Kokonor are names found in historic documents to describe the region.Gangchen Khishong, 2001. ''Tibet and Manchu: An Assessment of Tibet-Manchu Relations in Five Phases of ...

Fishbase
FishBase is a global species database of fish species (specifically finfish). It is the largest and most extensively accessed online database on adult finfish on the web.Marine Fellow: Rainer Froese ''Pew Environment Group''. Over time it has "evolved into a dynamic and versatile ecological tool" that is widely cited in scholarly publications. FishBase provides comprehensive species data, including information on , geographical distribution, and |
Taxa Named By Solomon Herzenstein
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] |
