John Treadwell Nichols
John Treadwell Nichols (June 11, 1883 – November 10, 1958) was an American ichthyologist and ornithologist. Life and career Nichols was born in Jamaica Plain, Boston, Massachusetts, the son of Mary Blake (Slocum) and John White Treadwell Nichols. In 1906 he studied vertebrate zoology at Harvard College, where he graduated with a Bachelor of Arts (AB). In 1907 he joined the American Museum of Natural History as assistant in the department of mammalogy. In 1913 he founded ''Copeia'', the official journal of the American Society of Ichthyologists and Herpetologists The American Society of Ichthyologists and Herpetologists (ASIH) is an international learned society devoted to the scientific studies of ichthyology (study of fish) and herpetology (study of reptiles and amphibians). The primary emphases of the .... In 1916 he described the long lost Bermuda petrel together with Louis L. Mowbray, Louis Leon Arthur Mowbray who first sighted this bird within a flock of other petrel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 springs ...

Taxa Named By John Treadwell Nichols
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 intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
