Lev Berg
Lev Semyonovich Berg, also known as Leo S. Berg (russian: Лев Семёнович Берг; 14 March 1876 – 24 December 1950) was a leading Russian geographer, biologist and ichthyologist who served as President of the Soviet Geographical Society between 1940 and 1950. He is known for his own evolutionary theory, nomogenesis (a form of orthogenesis incorporating mutationism) as opposed to the theories of Darwin and Lamarck. Life Lev Berg was born in Bessarabia in a Jewish family, the son of Simon Gregoryevich Berg, a notary, and Klara Lvovna Bernstein-Kogan. He graduated from the Second Kishinev Gymnasium in 1894. Like some of his relatives, Berg converted to Christianity in order to pursue his studies at Moscow State University. At Moscow University, Berg studied hydrobiology and geography. He later studied ichthyology and in 1928 was awarded he was also a member of the Russian Academy of Sciences. Lev Berg graduated from the Moscow State University in 1898. Between 190 ...

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 ...

Tanakia
''Tanakia'' is a genus of cyprinid fish, consisting of five species that occurs in Eastern Asia. The type species is the ''Tanakia limbata''. Genus is named for Shigeho Tanaka (1878-1974), “accomplished” ichthyologist of the Imperial University of Tokyo, who described ''Tanakia shimazui'' in 1908 and ''Pseudorhodeus tanago'' in 1909. Species There are currently 9 species of this genus: * ''Tanakia himantegus'' ( Günther, 1868) * ''Tanakia koreensis'' ( I. S. Kim & C. H. Kim, 1990) * ''Tanakia lanceolata'' (Temminck & Schlegel, 1846) * ''Tanakia latimarginata'' (Kim, Jeon & Suk, 2014) * ''Tanakia limbata'' (Temminck & Schlegel, 1846) (Oily bitterling) * ''Tanakia shimazui'' ( S. Tanaka (I), 1908) * ''Tanakia signifer'' ( L. S. Berg, 1907) * ''Tanakia somjinensis'' ( I. S. Kim & C. H. Kim, 1991) * ''Tanakia tanago The Tokyo bitterling (''Tanakia tanago'') is a temperate freshwater fish of the carp family (Cyprinidae). Taxonomically, it belongs to the subfamily Acheilo ...

Taxa Named By Lev Berg
In biology, a taxon (back-formation from ''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 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 system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
