The Salado Springs salamander (Eurycea chisholmensis) is a species of salamander in the family Plethodontidae. It is endemic to the vicinity of Salado, Texas. [1] [3] Its natural habitat is freshwater springs. It has been found only from a few springs that feed Salado Creek in Bell County, Texas.
An estimated 1.88 billion individuals of the southern redback salamander inhabit just one district of Mark Twain National Forest alone, about 1,400 tons of biomass. [7] Due to their modest size and low metabolism, they are able to feed on prey such as springtails , which are usually too small for other terrestrial vertebrates.
This terrestrial salamander has direct development. Its natural habitats are cloud forests at elevations of 1,200–1,500 m (3,900–4,900 ft) above sea level. It can be found in decaying wood, under bark of logs, under moss, and under pine logs. It can also be found off the ground. [1]
Plethodon is part of the family Plethodontidae (lungless salamanders) and the subfamily Plethodontinae.The genus Plethodon can be divided into two subgenera: the nominal subgenus Plethodon, which includes up to 49 eastern species (the bulk of diversity in the genus), and the subgenus Hightonia, [5] which includes 9 species native to the western part of North America.
The pathogen, unidentified up to then, had devastated fire salamander populations in the Netherlands. Molecular phylogenetics confirmed it as related to the well known chytrid B. dendrobatidis . Like this species, it causes chytridiomycosis , which is manifested in skin lesions and is lethal for the salamanders. [ 1 ]
The Scott Bar salamander (Plethodon asupak) is a species of salamander in the family Plethodontidae, endemic to the United States, where it is restricted to a very small range in the Scott River drainage in Siskiyou County, California, at altitudes between 700 and 1,300 metres (2,300 and 4,300 ft) above sea level.
The Cheat Mountain salamander is smallish, similar in size to the red-backed salamander, 3 to 4¾ inches (7½ to 12 cm) in total length (including tail), but is distinct in its black or dark brown dorsum (back) which is boldly marked with numerous small brassy, silver or white flecks. It lacks a dorsal stripe. The belly is dark gray to black.
The type locality has since been converted to a site for a hydroelectric dam, and other damming projects have flooded portions of the salamander's former range. [ 1 ] The frog's range includes several protected parks: Reserva Natural Privada Riomanso , Serrania de los Yariguies Integrated Management Regional District , Ranita Dorada ProAves ...
