Least Chub
The least chub (''Iotichthys phlegethontis'') is a species of freshwater ray-finned fish belonging to the family Leuciscidae Leuciscidae is a family of freshwater ray-finned fishes, formerly classified as a subfamily of the Cyprinidae, which contains the true minnows. Members of the Old World (OW) clade of minnows within this subfamily are known as European minnow ..., the shiners, daces and minnows. It is the only member of the monospecific genus ''Iotichthys''. This species is found only in Utah and more recently in Idaho in the United States. Due to habitat degradation and introduction of non-native fishes, it is currently limited to a few spring complexes in Utah and the Snake River Valley in Idaho. Species Description The least chub is a small fish, with a maximum size of less than . They have an olive-green black with steel blue upper sides and a golden stripe running from the upper end of the gill opening to the base of the caudal fin. Its lower sides and belly ar ...

David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he served as president of Indiana University Bloomington, Indiana University from 1885 to 1891. Jordan was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration", asserting that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and education Jordan was born in Gainesville (town), New York, Gainesville, New York, and grew up on a farm in upstate New York. His parents made an unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, ...

Habitat Destruction
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as the ...

Fish Described In 1874
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...

Endemic Fauna Of Utah
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 becoming ...

Pogonichthyinae
Pogonichthyinae is a subfamily of the freshwater fish family Leuciscidae, which contains the true minnows. Members of this family are known as American minnows or the North American (NA) clade of minnows. As the name suggests, all members of this family are found in North America (although they are not the only minnows native to North America, as Plagopterinae, Laviniinae, and Leuciscinae are also found there). Genera Pogonichthyinae contains the following genera; * ''Agosia'' Charles Frédéric Girard, Girard, 1856 (Longfin dace) * ''Alburnops'' Girard, 1856 * ''Algansea'' Girard, 1856 (Mexican chubs) * ''Aztecula'' David Starr Jordan, D.

Davis County, Utah
Davis County is a county in northern Utah, United States. As of the 2020 United States census, the population was 362,679, making it Utah's third-most populous county. Its county seat is Farmington, and its largest city by both population and area is Layton. Davis County is part of the Ogden- Clearfield, UT Metropolitan Statistical Area as well as the Salt Lake City- Provo- Orem, UT Combined Statistical Area. History The legislature of the provisional State of Deseret defined the county in an October 5, 1850, act, which also designated Farmington as the seat due to its location midway between boundaries at the Weber River on the north and the Jordan River on the south. It was named for Daniel C. Davis, a captain in the Mormon Battalion. The county boundaries were altered in 1852, 1854, 1855, and in 1862. In 1880 the county gained part of the islands and waters of Great Salt Lake that had previously been attached to Salt Lake County. The county boundary has remained un ...

Gambusia Affinis
The western mosquitofish (''Gambusia affinis'') is a North American freshwater poeciliid fish, also known commonly, if ambiguously, as simply mosquitofish or by its generic name, ''Gambusia'', or by the common name gambezi. Its sister species, the eastern mosquitofish ('' Gambusia holbrooki'') is also referred to by these names. Mosquitofish are small in comparison to many other freshwater fish, with females reaching a maximum length of and males a maximum length of . The female can be distinguished from the male by her larger size and a gravid spot at the posterior of her abdomen. The name "mosquitofish" was given because the fish eats mosquito larvae, and has been used more than any other fishes for the biological control of mosquitoes. Gambusia typically eat zooplankton, beetles, mayflies, caddisflies, mites, and other invertebrates; mosquito larvae make up only a small portion of their diet. Mosquitofish were introduced directly into ecosystems in many parts of the worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Chub Distribution
The degrees of comparison of adjectives and adverbs are the various forms taken by adjectives and adverbs when used to compare two entities (comparative degree), three or more entities (superlative degree), or when not comparing entities (positive degree) in terms of a certain property or way of doing something. The usual degrees of comparison are the ''positive'', which denotes a certain property or a certain way of doing something without comparing (as with the English words ''big'' and ''fully''); the ''comparative degree'', which indicates ''greater'' degree (e.g. ''bigger'' and ''more fully'' omparative of superiorityor ''as big'' and ''as fully'' omparative of equalityor ''less big'' and ''less fully'' omparative of inferiority; and the ''superlative'', which indicates ''greatest'' degree (e.g. ''biggest'' and ''most fully'' uperlative of superiorityor ''least big'' and ''least fully'' uperlative of inferiority.
