Bluetail Goodeid
The striped goodeid, bluetail goodeid or bluetail goodea (''Ataeniobius toweri'') is an endangered species of fish in the family Goodeidae. Its genus ''Ataeniobius'' is monotypic. It is endemic to the Río Verde and associated waters, including the Media Luna and Los Anteojitos lakes (all part of the Pánuco River basin), in San Luis Potosí, Mexico. The specific name of this fish honours its discoverer, the America evolutionary biologist William Lawrence Tower (1872–1955) of the University of Chicago The University of Chicago (UChicago, Chicago, or UChi) is a Private university, private research university in Chicago, Illinois, United States.

Carl Leavitt Hubbs
Carl Leavitt Hubbs (October 19, 1894 – June 30, 1979) was an American ichthyologist. Biography Early life Carl Leavitt Hubbs was born in Williams, Arizona, to Charles Leavitt and Elizabeth () Hubbs. His father had a wide variety of jobs (farmer, iron mine owner, newspaper owner). The family moved several times before settling in San Diego where he got his first taste of natural history. After his parents divorced in 1907, he lived with his mother, who opened a private school in Redondo Beach, California. His maternal grandmother Jane Goble Goss, one of the first female doctors, showed Hubbs how to harvest shellfish and other sea creatures. One of his teachers, impressed by Hubbs's abilities in science, recommended that he study chemistry at the University of Berkeley. The family moved once more to Los Angeles. In Los Angeles, George Bliss Culver, one of the many volunteers of David Starr Jordan, encouraged Hubbs to abandon his study of birds and instead to study fish, part ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Endangered Biota Of Mexico
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fish Of Mexico
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomi ...

Freshwater Fish Of Mexico
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. The term excludes seawater and brackish water, but 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. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is not alway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goodeinae
Goodeinae is a subfamily of splitfins from Mexico, part of the Family (biology), family Goodeidae. They are small fish which mostly live in fresh water, especially around Mesa Central, west of Mexico City. Members of the subfamily are also found in brackish water on both the east and west coasts. They typically have small ranges and many are seriously Threatened species, threatened (some already extinct). The subfamily takes its name from its type genus ''Goodea'' and so is ultimately named after the United States, American ichthyologist George Brown Goode (1851-1896). Genera The following genera make up the subfamily Goodeinae: * ''Allodontichthys'' Carl Leavitt Hubbs, C. L. Hubbs & Clarence Lester Turner, C. L. Turner, 1939 * ''Alloophorus'' Hubbs & Turner, 1939 * ''Allotoca'' Hubbs & Turner, 1939 * ''Ameca (fish), Ameca'' Robert Rush Miller, R. R.

William Lawrence Tower
William Lawrence Tower (22 December 1872– July 1967) was an American zoologist, born in Halifax, Massachusetts. He was educated at the Lawrence Scientific School (Harvard), the Harvard Graduate School, and the University of Chicago ( B. S., 1902), where he taught thereafter, becoming associate professor in 1911. Research Tower was notable for his experimental work in heredity, investigating the inheritance of acquired characteristics and the laws of heredity in beetles and publishin''An Investigation of Evolution in Chrysomelid Beetles of the Genus Leptinotarsa''(1906). This study is probably the first (albeit possibly discredited) of mutation in animals. He published also ''The Development of the Colors and Color Patterns of Coleoptera'' (1903) and, with Coulter, Castle, Davenport and East, an essay on ''Heredity and Eugenics'' (1912). Tower was caught up in personal and professional scandals. He resigned from the University of Chicago in 1917 following a very public di ...

Evolutionary Biology
Evolutionary biology is the subfield of biology that studies the evolutionary processes such as natural selection, common descent, and speciation that produced the diversity of life on Earth. In the 1930s, the discipline of evolutionary biology emerged through what Julian Huxley called the Modern synthesis (20th century), modern synthesis of understanding, from previously unrelated fields of biological research, such as genetics and ecology, systematics, and paleontology. The investigational range of current research has widened to encompass the genetic architecture of adaptation, molecular evolution, and the different forces that contribute to evolution, such as sexual selection, genetic drift, and biogeography. The newer field of evolutionary developmental biology ("evo-devo") investigates how embryogenesis is controlled, thus yielding a wider synthesis that integrates developmental biology with the fields of study covered by the earlier evolutionary synthesis.
