Salamander
Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela. Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders rarely have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs. Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. Some salamander species are fully aquatic throughout their lives, some take to the water intermittently, and others are entirely terrestrial as adults. This group of amphibians is capable of regenerating lost lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brook Salamander
Brook salamanders are a genus, ''Eurycea'', of salamanders native to North America. Taxonomy The genus ''Eurycea'' was first described by Constantine Samuel Rafinesque-Schmaltz in 1822, with a specimen of the spotted-tail salamander, ''Eurycea lucifuga'', from Kentucky. The Taxonomy (biology), taxonomy of the genus is somewhat confusing, as many of the species within it are poorly studied and are found only in very restricted ranges, or deep within caverns. Several species have even been described several times by different researchers, and some are often considered to be comparative anatomy, morphologically different enough to warrant being placed into their own genera. A recent taxonomic revision moved the Georgia blind salamander to this genus, which makes ''Haideotriton'' a synonym of ''Eurycea''. Many sources also refer to several species of the genus as cave salamanders, due to their choice of habitat, or as blind salamanders, due to their reduced eyes, or the antiquate ...

Endemism
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] |
United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Chamberlain's Dwarf Salamander
Chamberlain's dwarf salamander (''Eurycea chamberlaini'') is a species of salamander in the family Plethodontidae, endemic to the United States. Its natural habitats are temperate forests, rivers, and freshwater marshes. It is only found in the states of North Carolina and South Carolina. It was previously thought to be a color morph of the southeastern dwarf salamander (''Eurycea quadridigitata''), but was described in 2003 as a distinct species based on distinct morphology and behavior. A 2017 study reaffirmed it as being a distinct species. It was named after Edward Burnham Chamberlain, a former curator of the Vertebrate Zoology department at the Charleston Museum The Charleston Museum is a museum located in the Wraggborough neighborhood in Charleston, South Carolina. It is one of the oldest museums in the United States. Its highly regarded collection includes historic artifacts, natural history, decora ....

Hillis's Dwarf Salamander
Hillis's dwarf salamander (''Eurycea hillisi'') is a species of salamander endemic to the southern United States. Taxonomy It was previously thought to be a population of the southeastern dwarf salamander (''E. quadridigitata'') but a 2017 study found it to be a distinct species based on genetic evidence, and described it as ''E. hillisi''. It is named in honor of American evolutionary biologist David Hillis. It is unlikely that any previous studies had analyzed populations of this species. Distribution It is found throughout the southern half of Alabama outside of the Mobile Bay region, and ranges east into mid-central Georgia and south to the central Florida Panhandle The Florida Panhandle (also West Florida and Northwest Florida) is the northwestern part of the U.S. state of Florida; it is a Salient (geography), salient roughly long and wide, lying between Alabama on the north and the west, Georgia (U. ....

Western Dwarf Salamander
The western dwarf salamander (''Eurycea paludicola'') is species of salamander native to the southern United States. Taxonomy It was described in 1947 but later synonymized with the southeastern dwarf salamander (''Eurycea quadridigitata''). However, a 2017 study used . In addition, genetic studies indicate that it may be more closely related to the radiation of neotenic '' Eurycea'' of the Edwards Plateau in Texas than to the rest of the ''E. quadridigitata'' complex. Distribution It ranges from southern Mississippi east through Louisiana to eastern Texas.

Southeastern Dwarf Salamander
The southeastern dwarf salamander (''Eurycea quadridigitata''), formerly known as the dwarf salamander, is a species of salamander native to the southern United States, ranging primarily from southern North Carolina south to northern Florida, with some populations from southwestern Alabama to eastern Louisiana. Some sources refer to it as the four-fingered manculus, dwarf four-toed salamander, or the Florida dwarf salamander. Taxonomy A review of ''E. quadridigitata'' published in 2017 identified five cryptic species within ''E. quadridigitata'' based on molecular evidence.Wray, K. P., D. B. Means, and S. J. Steppan. 2017. Revision of the ''Eurycea quadridigitata'' (Holbrook 1842) complex of Dwarf Salamanders (Caudata: Plethodontidae: Hemidactyliinae) with a description of two new species.

Bog Dwarf Salamander
The bog dwarf salamander (''Eurycea sphagnicola'') is a species of salamander endemic to the southern United States. Taxonomy It was previously thought to be a population of the southeastern dwarf salamander (''E. quadridigitata'') but a 2017 study found it to be a distinct species based on genetic evidence, and described it as ''E. sphagnicola''. It is unlikely that any previous studies had analyzed populations of this species. It is the most divergent of the eastern species in the dwarf salamander complex, having diverged from the clade containing '' E. quadridigitata'', '' E. hillisi'', and '' E. chamberlaini'' during the late Oligocene to mid- Miocene, about 23-15 million years ago. Distribution It is found only in a small portion of the Gulf Coast of the United States, being found in the western Florida Panhandle and southern Alabama and Mississippi. It is likely the most geographically restricted of all species in the dwarf salamander complex. Habitat It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
