Cyprinodon Fontinalis
The Carbonera pupfish (''Cyprinodon fontinalis''), also known as the Perrito de carbonera, is a small, endangered species of pupfish in the family Cyprinodontidae. It is endemic to springs and associated waters at Bolsón de los Muertos in northwestern Chihuahua, Mexico. It was last rated by the IUCN in 1996 where considered endangered, but most subpopulations now appear to be extirpated, while a few are extinct in the wild (still survive in captivity). In 2012, it only survived in the wild in a single spring (having once occurred in nine), which also was the last remaining habitat for the largemouth shiner (''Cyprinella bocagrande'') and the dwarf crayfish ''Cambarellus chihuahuae ''Cambarellus'' is a genus of small freshwater crayfish in the family Cambaridae.

Cambarellus Chihuahuae
''Cambarellus'' is a genus of small freshwater crayfish in the family Cambaridae. The 19 species are found in Mexico (subgenus ''Cambarellus'') and the Gulf States of the United States (subgenus ''Pandicambarus''). Among the Mexican species, ''C. areolatus'', ''C. patzcuarensis'', and ''C. prolixus'' are considered seriously threatened by the IUCN, and ''C. alvarezi'' is already extinct. ''C. chihuahuae'' was also believed to be extinct until rediscovered in 2012. ''C. alvarezi'' and four undescribed, extinct ''Cambarellus'' species were restricted to desert spring systems in southwestern Nuevo León; each one shared its habitat with a ''Cyprinodon'' pupfish (these are also fully extinct or extinct in the wild). An orange form of ''C. patzcuarensis'' is regularly seen in the freshwater aquarium trade. Species The genus contains the following species: ;Subgenus ''Cambarellus (Cambarellus)'' *†''Cambarellus alvarezi'' (Villalobos, 1952)Villalobos, A. (1952). Estudios de los ...

Taxa Named By Robert Rush Miller
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] |

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 and invasive species. 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 considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Fish
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 643 endangered fish species. 4.2% of all evaluated fish species are listed as endangered. The IUCN also lists ten fish subspecies as endangered. Of the subpopulations of fishes evaluated by the IUCN, 24 species subpopulations have been assessed as endangered. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by ''critically endangered'' species, which meet the quantitative criteria for endangered species. Critically endangered fishes are listed separately. There are 1098 fish species which are endangered or critically endangered. Additionally 3191 fish species (21% of those evaluated) are listed as ''data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have smal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of The Chihuahuan Desert
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 Mexico
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. ...

Endemic Fish Of Mexico
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyprinodon
''Cyprinodon'' is a genus of pupfishes found in waters that range from fresh to hypersaline. The genus is primarily found in Mexico, the Caribbean Islands and southern United States (Arizona, California, Florida, Nevada, New Mexico, Oklahoma and Texas), but ''C. variegatus'' occurs as far north as Massachusetts and along the entire Gulf of Mexico coastline, and ''C. dearborni '' and ''C. variegatus'' are found in northern South America.Martin, C. H., and P. C. Wainwright (2013). ''Multiple Fitness Peaks on the Adaptive Landscape Drive Adaptive Radiation in the Wild.'' Science 339(6116): 208-211. Many species have tiny ranges and are highly threatened, in some cases already extinct. ''Cyprinodon'' are small; the largest reaches in length and most other species only reach about half that size. Distribution and habitat A few ''Cyprinodon'' species have quite large ranges, notably '' C. variegatus'', but the vast majority have small ranges, typically restricted to one or two Mexi ...

Largemouth Shiner
The largemouth shiner (''Cyprinella bocagrande'') is a critically endangered species of cyprinid fish. It is found only in the Guzmán Basin in northwestern Chihuahua, Mexico, where it is called ''sardinita bocagrande''. In 2012, it only survived in a single spring, which also was the last remaining habitat for the Carbonera pupfish (''Cyprinodon fontinalis'') and the dwarf crayfish '' Cambarellus chihuahuae''. As this single spring was declining, it was decided to move some individuals of all three species to a nearby refuge in 2014 as a safeguard. The largemouth shiner grows to a standard length Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish m ... of .
