Etheostoma Faulkneri
The Yoknapatawpha darter (''Etheostoma faulkneri'') is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae. It is endemic to the Yocona River watershed of north-central Mississippi in the United States. The Yoknapatawpha darter was initially considered to be a unique clade of the Yazoo darter. Based on mitochondrial DNA, it was initially determined that there are two monophyletic clades, those in the Little Tallahatchie River and those in the Yocona River drainages. Further genetic and morphological analyses determined the two populations were different species, with ''E. raneyi'' in the Little Tallahatchie River watershed, while the population in the Yocona River watershed was described as a new species, ''E. faulkneri''. Description Yoknapatawpha darters grow up to standard length (males) and (females). Distribution and habitat The Yoknapatawpha darter inhabits small, clear, mostly spring-fed streams with substra ...

NatureServe
NatureServe, Inc. is a non-profit organization based in Arlington County, Virginia, United States, US, that provides proprietary wildlife conservation-related data, tools, and services to private and government clients, partner organizations, and the public. NatureServe reports being "headquartered in Arlington, Virginia, with regional offices in four U.S. locations and in Canada." In calendar year 2011 they reported having 86 employees, 6 volunteers, and 15 independent officers.

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery biology. Overall length Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. This measurement excludes the length of the caudal (tail) fin. Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes ( lampreys) and usually Elasmobranchii (shark Sharks are a group of elasmobranch cartilaginous fish characterized by ...

Endemic Fish Of The United States
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 becomin ...

Yalobusha County, Mississippi
Yalobusha County ( ) is a county located in the U.S. state of Mississippi. As of the 2020 census, the population was 12,481. It has two county seats, Water Valley and Coffeeville. History ''Yalobusha'' is a Native American word, likely from the Muskogee language family, meaning " tadpole place." This region was long a traditional homeland of bands of both the Choctaw and Chickasaw Indian tribes, who occupied lands in present-day Mississippi and Alabama. In 1816, General Andrew Jackson ordered the surveying of the line between the Choctaw and Chickasaw peoples. The line as surveyed cut almost a perfect diagonal across the area of present-day Yalobusha County. European Americans increasingly encroached on the Native American territories of the Southeast and, after being elected as president in 1828, Jackson gained passage of the Indian Removal Act of 1830, to force tribes out of lands east of the Mississippi River. In 1830, the Choctaw ceded their Mississippi lands to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...
