Empetrichthys
''Empetrichthys'' is a genus of splitfins endemic to the state of Nevada in the United States.In 1989 they only had an estimated population of 24800, while its two other subspecies had gone extinct. This species mating season typically falls in spring. These animals are in danger and facing threats because their water is drying out because of pumping of ground water for agricultural developments. Species There are currently two recognized species in this genus: * ''Empetrichthys latos'' R. R. Miller, 1948 ** †''Empetrichthys latos concavus'' R. R.

Empetrichthys Merriami
The Ash Meadows killifish (''Empetrichthys merriami'') is a species of killifish from the subfamily Empetrichthyinae, part of the family Goodeidae, which was first documented by C. H. Gilbert in 1893 and historically occupied numerous springs near Ash Meadows, Nye County, Nevada, United States. This species was last seen in 1948 and is believed to have gone extinct in the early 1950s, likely as a result of habitat alteration and competition with and predation by introduced crayfish '' Procambarus clarkii'', mosquitofish ('' Gambusia affinis''), black mollies ('' Poecilia sphenops''), and bullfrogs ('' Rana catesbeiana''). The common name of the genus ''Empetrichthys'' has since been changed from killifish to poolfish. The specific name honours the American naturalist and physician C. Hart Merriam (1855-1942), who led Death Valley (California, USA) expedition, during which he and Vernon Orlando Bailey (1864-1942) co-collected the type. References Fish described in 189 ...

Splitfin
Goodeidae is a family of teleost fish endemic to Mexico and some areas of the United States. Many species are known as splitfins. This family contains about 50 species within 18 genera. The family is named after ichthyologist George Brown Goode (1851-1896). Distribution The family is divided into two subfamilies, the Goodeinae and the Empetrichthyinae. The Goodeinae are endemic to shallow freshwater habitats in Mexico, particularly along the Mesa Central area (especially the Lerma River basin, smaller rivers directly south of it and inland to around the Valley of Mexico region), with some species found in brackish fringes at the Pacific coast, and north to central Durango, central Sinaloa and north San Luis Potosí. There are about 45 species of Goodeinae in 16 genera (some list 2 additional genera). The Empetrichthyinae are found in the southwestern Great Basin in Nevada, the United States, and contains 4 species in 2 genera. Physical information The name "splitfin" come ...

Freshwater Fish Genera
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh ...

Charles Henry Gilbert
Charles Henry Gilbert (December 5, 1859 in Rockford, Illinois – April 20, 1928 in Palo Alto, California) was a pioneer ichthyologist and fishery biologist of particular significance to natural history of the western United States. He collected and studied fishes from Central America north to Alaska and described many new species. Later he became an expert on Pacific salmon and was a noted conservationist of the Pacific Northwest. He is considered by many as the intellectual founder of American fisheries biology. He was one of the 22 "pioneer professors" (founding faculty) of Stanford University. Early life and education Born in Rockford, Illinois, Gilbert spent his early years in Indianapolis, Indiana, where he came under the influence of his high school teacher, David Starr Jordan (1851‒1931). When Jordan became Professor of Natural History at Butler University in Indianapolis, Gilbert followed and received his B.A. degree in 1879. Jordan moved to Indiana University, ...

Robert Rush Miller
Robert Rush Miller (April 23, 1916 – February 10, 2003) "was an important figure in American ichthyology and conservation from 1940 to the 1990s." He was born in Colorado Springs, earned his bachelor's degree at University of California, Berkeley in 1938, a master's degree at the University of Michigan in 1943, and a Ph.D. at the University of Michigan in 1944. He received tenure at the University of Michigan in 1954. Together with W. L. Minckley, he discovered a new species of platyfish, ''Xiphophorus gordoni'', that they named in honor of Dr Myron Gordon. He served as the ichthyological editor of ''Copeia'' from 1950 to 1955. Fish described * ''Chortiheros wesseli'' R. R. Miller 1996 - Cichlid * '' Cualac tessellatus'' R. R.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...
