Catostomus Fumeiventris
The Owens sucker (''Catostomus fumeiventris'') is a fish in the family Catostomidae which is endemic to California. Description The Owens sucker is similar to the Tahoe sucker (''Catostomus tahoensis'') but it has coarser scales and is duller in colour. The adults are slaty coloured, although some individuals can be very dark, with dusky bellies which are especially noticeable in spawning males. It grows to a maximum size of 50 cm but is more usually around 30 cm in total length. Distribution It is endemic to the Owens River in the Owens Valley of eastern California and has been introduced into June Lake in the Mono Lake basin and to the Santa Clara River system as a result of a release of water from the Owens River through the Los Angeles Aqueduct. Although the status of the population in the Santa Clara system is uncertain and any introduced fish may hybridise with the Santa Ana sucker (''Catostomus santaanae''). It is abundant in the Crowley Lake with population ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Los Angeles Aqueduct
The Los Angeles Aqueduct system, comprising the Los Angeles Aqueduct (Owens Valley aqueduct) and the Second Los Angeles Aqueduct, is a water conveyance system, built and operated by the Los Angeles Department of Water and Power. The Owens Valley aqueduct was designed and built by the city's water department, at the time named The Bureau of Los Angeles Aqueduct, under the supervision of the department's Chief Engineer William Mulholland. The system delivers water from the Owens River in the Eastern Sierra Nevada Mountains to Los Angeles, California. The aqueduct's construction was controversial from the start, as water diversions to Los Angeles eliminated the Owens Valley as a viable farming community. Clauses in the city's charter originally stated that the city could not sell or provide surplus water to any area outside the city, forcing adjacent communities to annex themselves into Los Angeles. The aqueduct's infrastructure also included the completion of the St. Francis Dam i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of The Great Basin
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of The United States
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 wa ...

Fish Of The Western United States
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...

Endemic Fauna Of California
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catostomus
''Catostomus'' is a genus of fish belonging to the family Catostomidae, commonly known as suckers. Most members of the genus are native to North America, but '' C. catostomus'' is also found in Russia. Fish from different species of the genus are known to readily hybridize with each other. Characteristics The members of this genus have nearly cylindrical bodies. They have large, horizontal mouths, and their lips are very much papillose. They have complete lateral lines. They have from 54 to 124 scales, seven to 17 dorsal rays, usually seven anal rays, and 20 to 44 thin, unbranched rakers on their first gill arches. Their gas bladders have two chambers. The young of many of the species in the genus have three dark grey blotches along their sides. Species Currently, 28 recognized species are in this genus: * ''Catostomus ardens'' D. S. Jordan & C. H. Gilbert, 1881 (Utah sucker) * ''Catostomus bernardini'' Girard, 1856 (Yaqui sucker) * ''Catostomus bondi'' G. R. Smith, J. D ...

Lake Sabrina
Lake Sabrina is a lake created by damming the middle fork of Bishop Creek. It is located south-west of Bishop, California on California State Route 168, in the Inyo National Forest. It has a cafe as well as a dock. The dam was built in 1907–8 to supply a constant flow of water to the hydraulic power plants. The lake is part of the Bishop Creek system. Local residents pronounce the lake "Sah-bry-nuh;" however, the lake was originally named after Mrs. Sabrina (pronounced: suh-BREE-nuh) Hobbs, wife of C.M. Hobbs first General Manager of California Nevada Power Company which built the dam. The reason for the lake's name pronunciation changing over the years is unclear. The segment of the State Route 168 from Lake Sabrina east to the community of Aspendell is subject to closure to most vehicles during the winter months, usually not opening until mid- or late-April, due to snow removal. The winter road closure gate is actually located to the southwest of Aspendell. See also *Li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convict Lake
Convict Lake (Mono: ''Wit-sa-nap'') is a lake located in Mono County, California, United States, situated in the Sherwin Range of the Sierra Nevada. It is known for its turquoise-blue water, the dramatic mountains (including Mount Morrison) that surround it, the trout fishing it affords, and its unusual history. The lake was renamed from its traditional Mono name by American settlers after an incident on September 23, 1871, in which a group of convicts escaped from prison in Carson City, Nevada, and took refuge near the lake. They were pursued by a posse, and after it caught up to the convicts, a shootout followed, in which a number of both posse members and convicts were killed or wounded. The remaining convicts who survived initially escaped but were eventually captured to be taken back to prison. They were lynched instead. Geography Convict Lake was originally carved out by glaciers. The lake's surface is approximately above sea level, with its greatest depths approxima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crowley Lake
Crowley Lake is a reservoir on the upper Owens River in southern Mono County, California, in the United States. Crowley Lake is south of Mammoth Lakes. The lake was created in 1941 by the building of the Long Valley Dam by the Los Angeles Department of Water and Power (DWP), as storage for the Los Angeles Aqueduct and for flood control. The dam is high and impounds . For more on the history of the lake, see Owens Lake. It is known for its trout fishing. Between 6,000 and 10,000 anglers hit the lake on opening day. Crowley Lake Fish Camp, run in cooperation with the Los Angeles Department of Water and Power, is the only way to access the lake, and visitors can rent boats, book camping sites, and buy supplies at the Fish Camp. The lake is named after Fr. John J. Crowley, "the desert Padre", who was a key figure in Owens Valley history and a local hero. When it became obvious that the city of Los Angeles's appropriation of the water supply had made agriculture impossible in th ...

Santa Ana Sucker
The Santa Ana sucker (''Catostomus santaanae'') is a freshwater ray-finned fish, endemic to California. It is closely related to the mountain sucker and has dark grey upper parts and silvery underparts. It grows to a maximum length of , but most adults are much smaller than this. It feeds on algae, diatoms and detritus on the floor of shallow streams with sand, gravel or cobble bottoms. It is found in only a few streams in southern California, and many of these in the Greater Los Angeles metropolitan area have been restricted to concrete channels. Because of its small area of occupancy and vulnerability, the International Union for Conservation of Nature has rated this fish as "endangered". Description The Santa Ana sucker is closely related to the mountain sucker, and quite similar in appearance. Color is dark grey above and silvery-white below; the sides have a faint pattern of darker blotches and stripes. There are distinct notches where the upper and lower lips meet, and the ...
