Cambarus Veteranus
The Guyandotte River crayfish (''Cambarus veteranus'') is a species of crayfish found in a small stream system in Wyoming County, West Virginia, US. They are closely related to the Big Sandy crayfish, and until recently, the two were thought to belong to the same species. The Guyandotte River Crayfish is currently listed as Data Deficient by the IUCN and was listed under the Endangered Species Act with the Big Sandy Crayfish on April 4, 2016. Description Adult Guyandotte river crayfish are typically to in length. Their shell covers range in colour from olive brown to light green with a blue cervical groove ranging in shade from light blue to aqua. Their walking legs are blue with chelae ranging in colour from light blue to a blue green. Some ways to differentiate the Guyandotte River Crayfish from the Big Sandy Crayfish include the Big Sandy Crayfish having a narrower rostrum and claw set. Guyandotte River Crayfish also have a lateral impression at the bottom of the station ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Walter Faxon
Walter Faxon (February 4, 1848 – August 10, 1920) was an American ornithologist and carcinologist. He was born at Jamaica Plain, Massachusetts, where he grew up. He received three degrees from Harvard University. One of his greater ornithological achievements was demonstration that Brewster's warbler is a hybrid. He spent many years researching and classifying many American crayfish, including the genera ''Astacus'', ''Orconectes'', and ''Procambarus'', and contributed to at least 20 different scientific papers. Following a 2017 review, carried out by Oxford University, the former ''Faxonius'' subgenus of ''Orconectes'' was raised to a full genus as the subgenera were not monophyletic In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants.

Taxa Named By Walter Faxon
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 ...

Crustaceans Described In 1914
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans ( Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and ...

Cambaridae
The Cambaridae are the largest of the four families of freshwater crayfish, with over 400 Species. Most of the species in the family are native the United States east of the Great Divide and Mexico, but fewer range north to Canada, and south to Guatemala and Honduras. Three live on the island of Cuba. The species in the genus ''Cambaroides'' are the only found outside North America, as they are restricted to eastern Asia. A few species, including the invasive ''Procambarus clarkii'' and '' Faxonius rusticus'', have been introduced to regions far outside their native range (both in North America and other continents). Conversely, many species have tiny ranges and are seriously threatened; a few are already extinct. A 2006 molecular study suggested that the family Cambaridae may be paraphyletic, with the family Astacidae Astacidae is a family of freshwater crayfish native to Europe and western North America. The family is made up of four extant (living) genera: The genera '' ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

United States Fish And Wildlife Service
The United States Fish and Wildlife Service (USFWS or FWS) is an agency within the United States Department of the Interior dedicated to the management of fish, wildlife, and natural habitats. The mission of the agency is "working with others to conserve, protect, and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people." Among the responsibilities of the USFWS are enforcing federal wildlife laws; protecting endangered species; managing migratory birds; restoring nationally significant fisheries; conserving and restoring wildlife habitats, such as wetlands; helping foreign governments in international conservation efforts; and distributing money to fish and wildlife agencies of U.S. states through the Wildlife Sport Fish and Restoration Program. The vast majority of fish and wildlife habitats are on U.S. state, state or private land not controlled by the United States government. Therefore, the USFWS works closely with private g ...

Critical Habitat
Critical habitat is a habitat area essential to the conservation of a listed species, though the area need not actually be occupied by the species at the time it is designated. This is a specific term and designation within the U.S. Endangered Species Act-ESA. Contrary to common belief, designating an area as critical habitat does not preclude that area from development. Rather, a critical habitat designation affects only federal agency actions. Such actions include federally funded activities or activities requiring a federal permit. Designation process Critical habitat must be designated for all threatened species and endangered species under the Endangered Species Act, with certain specified exceptions. Designations of critical habitats must be based on the best scientific information available and in an open public process within specific timeframes. Unless deemed necessary for the species' continued existence, critical habitat do not include the entire geographical area occup ...

Landscape Connectivity
In landscape ecology, landscape connectivity is, broadly, "''the degree to which the landscape facilitates or impedes movement among resource patches''". Alternatively, connectivity may be a continuous property of the landscape and independent of patches and paths.Fischer, J. and D.B. Lindenmayer. 2006. Beyond fragmentation: the continuum model for fauna research and conservation in human-modified landscapes. Oikos, 112: 473–480. Connectivity includes both structural connectivity (the physical arrangements of disturbance and/or patches) and functional connectivity (the movement of individuals across contours of disturbance and/or among patches). Functional connectivity includes actual connectivity (requires observations of individual movements) and potential connectivity in which movement paths are estimated using the life-history data. A similar but different concept proposed by Jacques Baudry, landscape connectedness, refers to structural links between elements of spatial struct ...

Sedimentation
Sedimentation is the deposition of sediments. It takes place when particles in suspension settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or electromagnetism. Settling is the falling of suspended particles through the liquid, whereas sedimentation is the final result of the settling process. In geology, sedimentation is the deposition of sediments which results in the formation of sedimentary rock. The term is broadly applied to the entire range of processes that result in the formation of sedimentary rock, from initial erosion through sediment transport and settling to the lithification of the sediments. However, the strict geological definition of sedimentation is the mechanical deposition of sediment particles from an initial suspension in air or water. Sedimentation may pertain to ob ...
