The Allegheny Mountain dusky salamander (Desmognathus ochrophaeus) is a species in the Plethodontidae (lungless salamander) family native to eastern North America.
It is found in the eastern United States, as well as in the Niagara Glen Nature Reserve adjacent to the lower Niagara River in southern Ontario, and a single disjunct population in southern Quebec, Canada. [2] Its natural habitats are temperate forests, rivers, intermittent rivers, freshwater springs, and rocky areas. [1]
Desmognathus ochrophaeus is a medium-sized salamander that can grow to about 10 cm in length. Adults are brownish and can have a widely variable coloration pattern. Usually, it has a light stripe down the back, with a row of dark spots on the centre and flanked by dark pigments. As in all members of the genus, the hind legs are larger and stouter than the front legs. This species belongs to the "lungless salamander" family (Plethodontidae), whose adults must keep their skin moist to breathe. It is a somewhat terrestrial salamander that can be found under stones, logs, and bark near springs, streams, and other areas where the ground is saturated with water. [3]
Ontario's Endangered Species Act, 2007, protects D. ochrophaeus from being killed, harmed, or possessed. Salamanders are protected on Niagara Parks Commission property under the Niagara Parks Act, which makes it illegal to hunt, trap, or molest any animal without a government permit. A Dusky Salamander Recovery Team has been established to develop a strategy for the recovery of this species and the related northern dusky salamander (D. fuscus). [3]
Canadian populations of D. ochrophaeus are divided into two segments, each of which is designated endangered under Schedule 1 of the Species at Risk Act. The first is the Carolinian population, native to Ontario, which received endangered status in 2009. [4] The second population, the Appalachian population, is found in a small area of Quebec and was designated as endangered in April 2021. [5] Previously, from 1998 to 2007, the populations were treated together as a COSEWIC "Species of Special Concern." [4] [5]
Desmognathus is a genus of lungless salamanders in the family Plethodontidae known as dusky salamanders. They range throughout the eastern United States as far west as Texas, and north to southeastern Canada.
The Cumberland dusky salamander is a species of salamander in the family of lungless salamanders, Plethodontidae. It is endemic to the United States. Its natural habitats are temperate forests and rivers. This species is threatened by habitat loss.
The seepage salamander is a small, terrestrial species of salamander in the family Plethodontidae. It is endemic to the United States. They are found in small areas of Tennessee, North Carolina, Georgia, and Alabama. Its natural habitats are temperate forests, intermittent rivers, and freshwater springs. It gets its name from the seepages around which it lives. It is very similar in its appearance and life history to the pygmy salamander. These two species differ greatly from the other Desmognathus species. They are the smallest salamanders in the genus, measuring only 3–5 cm (1–2 in) in length. They are also the only two terrestrial, direct-developing Desmognathus species. However, the two species are not often seen to coexist, differing in distribution by elevation; although there are exceptions. The seepage salamander is currently listed as Near Threatened, with its numbers declining in most of states in which it is found. It is threatened by habitat loss, with logging having a major effect.
The Ouachita dusky salamander is a species of salamander in the family Plethodontidae. It is endemic to the states of Arkansas and Oklahoma in the United States. The specific epithet is in honor of Herbert Hutchinson Brimley and his younger brother, Clement Samuel Brimley, both of whom were zoologists.
The Carolina mountain dusky salamander is a species of salamander in the family Plethodontidae.
Desmognathus fuscus is a species of amphibian in the family Plethodontidae. The species is commonly called the dusky salamander or northern dusky salamander to distinguish it from populations in the southern United States which form several distinct species, the southern dusky salamanders. The northern dusky salamander is the most widespread representative of its genus in Canada. It can be found in eastern North America from extreme eastern Canada in New Brunswick south to South Carolina. The size of the species' total population is unknown, but is assumed to easily exceed 100,000. The species' habitat differs somewhat geographically; dusky salamanders in the northern part of the range prefer rocky woodland streams, seepages, and springs, while those in the south favor floodplains, sloughs, and muddy places along upland streams. They are most common where water is running or trickling. They hide under various objects, such as leaves or rocks, either in or near water. Alternatively, they may enter burrows for protection. The dusky salamander lays its eggs close to water under moss or rocks, in logs, or in stream-bank cavities. The larval stage which follows is normally aquatic.
The imitator salamander is a species of salamander in the family Plethodontidae. It is endemic to the Appalachian Mountains in the Eastern United States.
The shovelnose salamander is a species of salamander in the family Plethodontidae. It is endemic to the United States.
The seal salamander is a species of lungless salamander that is endemic to the Eastern United States.
The ocoee salamander is a species of salamander in the family Plethodontidae. This salamander has a variety of colors and patterns, and got its name from Tennessee state wildflower. Its natural habitats are temperate forests, rivers, intermittent rivers, freshwater springs and wet rocks in mountainous areas of the Southeastern United States. It was first described by Nicholls in 1949. They are territorial and feed on small invertebrates. It is widely distributed in the southeastern United States and is listed as "Least Concern" by the International Union for Conservation of Nature.
The Blue Ridge dusky salamander is a species of salamander in the family Plethodontidae.
The blackbelly salamander is a species of salamander in the family Plethodontidae. It is endemic to the United States. Its natural habitats are rivers, intermittent rivers, and freshwater springs. It is threatened by habitat loss.
The black mountain salamander is a species of salamander in the family Plethodontidae.
The spring salamander is a species of salamander in the family Plethodontidae. It is found in Canada and the United States. The genus, Gyrinophilus, means "tadpole lover" and refers to the long period of time it spends as a gilled larva before maturing. The specific epithet, porphyriticus, is Latin from Greek, meaning the color of porphyry, a purple stone, and this salamander has also been called the purple salamander.
The many-lined salamander is a species of salamander in the family Plethodontidae. It is the only species of the monotypic genus Stereochilus. It is endemic to the United States.
Valentine's southern dusky salamander is a species of salamander in the family Plethodontidae. It is endemic to the southeastern United States.
