The red-cheeked salamander (Plethodon jordani), also known as the Jordan's salamander, Jordan's redcheek salamander, or Appalachian woodland salamander, is a species of salamander in the family Plethodontidae. It is endemic to the Appalachian Mountains in the southeastern United States. [2]

Description

The red-cheeked salamander is a uniform steely grey colour with conspicuous red, orange or yellow patches on the side of the head. The imitator salamander (Desmognathus imitator) is thought to be a mimic and is very similar in appearance but has a pale line joining jaw to eye and more robust hind legs. [3]

Distribution and habitat

The red-cheeked salamander is found in mountainous areas of the southeastern United States. The main populations are along the border between North Carolina and Tennessee, but separate populations occur in Rabun County, Georgia. The altitude range is 210 to 1950 metres (700 to 6400 ft), but a few specimens are found below 600 metres (2,000 ft). Almost the whole altitude range occurs within the boundaries of the Great Smoky Mountains National Park. The red-cheeked salamander is a terrestrial species and is found in both hardwood and coniferous forests, particularly in the Southern Appalachian spruce–fir forest. It is plentiful in areas with a ground cover of moss and leaf litter among large boulders. [4]

The red-cheeked salamander conceals itself during the day under rocks and in or under rotten logs. It has extensive shallow burrows through which it can move about. At night and during rain it emerges to the surface to forage. A salamander has a small home range which is about 11 square metres (120 sq ft) for a male and 2.8 square metres (30 sq ft) for a female. When displaced by a distance of 300 metres (980 ft) or more, most salamanders managed to return to their home. The red-cheeked salamander feeds on small invertebrates including worms, snails, springtails, spiders, insects and insect larvae. [3] [4]

Creatures that prey on the red-cheeked salamander include birds, the common garter snake (Thamnophis sirtalis), the blackbelly salamander (Desmognathus quadramaculatus) and the spring salamander (Gyrinophilus porphyriticus). When attacked, it turns its tail towards the predator and emits a sticky, noxious mucus. It may bite the head of a snake or twine its tail round its head. Another defensive strategy is the autotomisation of its tail, which may leave the predator a tasty morsel while the salamander flees. [4]

Little is known of the breeding habits of the red-cheeked salamander, but they are likely to be similar to those of other members of the genus Plethodon with a clutch of eggs being brooded by the female and each egg developing directly into a juvenile without an intervening larval stage. [4]

Status

The red-cheeked salamander is listed as being "Near Threatened" in the IUCN Red List of Threatened Species. The population of the species appears to be stable, but the area of its range is less than 5,000 square kilometres (1,900 sq mi). Balancing this, it is common in many locations, tolerates forestry disturbance and lives completely within the confines of the national park. The main threats may be acid rain, climate change and the damage to forests caused by the balsam woolly adelgid (Adelges piceae). [1]

<i>Plethodon</i> Genus of amphibians

Plethodon is a genus of salamanders in the family Plethodontidae. They are also known as woodland salamanders or, more rarely, slimy salamanders. All members of the genus are endemic to North America. They have no aquatic larval stage. In some species, such as Plethodon cinereus, the red-backed salamander, eggs are laid underneath a stone or log. Young hatch in the adult form. Members of Plethodon primarily eat small invertebrates. The earliest known fossils of this genus are from the Hemphillian of Tennessee in the United States.

It is threatened by habitat loss and potentially in the future by the fungal disease Batrachochytrium salamandrivorans.

<i>Desmognathus fuscus</i> Species of amphibian

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.

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.

<span class="mw-page-title-main">Northern gray-cheeked salamander</span> Species of amphibian

The northern gray-cheeked salamander is a species of salamander in the family Plethodontidae and endemic to the Blue Ridge Mountains and Appalachian Mountains in the eastern United States. It is closely related to the Red-cheeked salamander and the Red-legged salamander. Its natural habitat is temperate forests. It is found under moss, rocks, logs, and bark in cool, moist forests above 2500 feet. Especially found in spruce-fir forests. The Gray-cheeked Salamander commonly eats millipedes, earthworms, crane flies, spiders, and centipedes and less commonly eats ants, mites, and springtails. They eat spiders, moths, flies, beetles, bees, and snails. The male and female perform a courtship, where the male nudges the female with his snout, does a foot dance, then circles under the female and the two then walk together. Like other salamanders, they do not migrate or aggregate during breeding season. It is threatened by habitat loss.
