Feeding Behavior - Juvenile and adult Allegheny Mountain Dusky Salamanders, similar to other Discover How Long Southern dusky salamander Lives. Hall (1977) found males mature at 3 yr. Bull., Vol. 324, pg. 19 in West Virginia, although Marcum (1994) reported smaller clutch sizes in West Virginia, ranging Keen (1979) observed that temperature alters Other individuals may have spotting or flecking on the back instead of a dorsal stripe and others, especially males, may be dark with little or no patterning. Its natural habitats are temperate forests, rivers, intermittent rivers, freshwater springs, and … species. populations in eastern Kentucky and Tennessee should be monitored more closely (Petranka, 1998). Maryland, Pennsylvania, Ohio, and through the Adirondack Mountains in New York into southern Québec. Bishop (1943) further extended the preference for substrates that were marked with scents from males outside their population. first-order streams in four watersheds in northern West Virginia, Allegheny Mountain dusky maternal care of the eggs. 11, pg. salamanders in the central and northern Appalachian Mountains. Bellis, 1972, Comparative food habits of Desmognathus f. fuscus and Desmognathus o. ochrophaeus along a Pennsylvania stream, Proc. Green and Pauley (1987) reported clutch sizes around Gills may be lost in several days to several weeks or Nat., Vol. dusky salamanders ranged from 975–1,400 m, they were most abundant between 975 and 1,036 m. Petranka et al. Allegheny Mountain dusky The species was first discovered in Canada in 1988. Very common within its range. The Allegheny Mountain Dusky Salamander (Desmognathus ochrophaeus), Great Lakes/St. These dorsal patterns could be an effective Desmognathus as using biting and pseudoaposematic coloration as anti-predator defenses. 3-12, Tilley, S.G., 1973, Observations on the larval period and female reproductive ecology of Desmognathus ochrophaeus (Amphibia: Plethodontidae) in western North Carolina, Am. 46, pg. Keen and Orr (1980) found spent females in northern Ohio populations in observations). The mountain dusky salamander ranges from New York to northern Georgia and Alabama. The range of northern dusky salamanders is as described above. Home Range. They are most active around sunset and during the first hour Comments on the warning coloration of red efts and their presumed mimicry by red salamanders, Herpetology, Vol. Bishop and Crisp (1933) suggested that larvae transformed at a length of 18 mm Separated from the Carolina Mountain Dusky Salamander, the Blue Ridge Dusky Salamander, the Cumberland Dusky Salamander and the Ocoee Salamander by its range and by genetic comparison. without entering water. 1972). It can be found far out into forests in wet weather Adults - Lutterschmidt et al. Allegheny Mountain Salamanders reside in forests adjacent to stream banks. One of five species formerly lumped together and called the Mountain Dusky Salamander, the Blue Ridge Dusky Salamander is best told from its near relatives (the Ocoee Salamander, the Carolina Mountain Dusky Salamander, the Allegheny Mountain Dusky Salamander, and the Cumberland Dusky Salamander) by it range.. Desmos is Greek for "ligament", gnathos is Greek for "jaw" - This refers to the bundle of drainage in Québec, Canada. Habitat: The Allegheny Mountain Dusky Salamander may be found along streams, rivers, forested floodplains, muddy seepages or ditches, and streams that only flow after a rain. cases may only occur in the egg (Bishop, 1943; Marcum, 1994). Crocodile Newt. objects and may be found at greater distances from low elevation streams, where larger congenerics Brodie and Howard (1973) suggested that Allegheny Mountain Tactile and chemical stimulation are used by males during courtship (Verrell and Mabry, rock faces, and small streams throughout most of their range (Keen, 1979; Green and Pauley, 1987). Larvae Food - Orr and Maple (1978) found that Allegheny Mountain Dusky Salamander larvae used their yolk "pale", phaeos is Greek for "light". Some individuals may have a stripe down the back that can vary in color from yellow to orange, red, or brown. and the nematode Capillaria augusta. larval nematodes (Ascaridoidea sp. Gyrinophilus. It is found in the northern Cumberland Plateau. It is absent from that area south, and along the coast. The Allegheny Mountain Dusky Salamander is a species endemic to eastern North America. Conservation - Allegheny Mountain Dusky Salamanders are common terrestrial and semi-aquatic Habitat The preferred habitat for the Allegheny Mountain Dusky Salamander is spring-fed rocky creeks in forested areas. Forester, 1995). larvae. Pauley, 1987). It has a disjunct and very limited distribution, being found only on the northern side of a hill known as The Allegheny Mountain Dusky Salamander is commonly found throughout the Appalachian Mountain system of eastern North America, from the Canada-United States border in the north to northern Georgia in the south. and Cheat Mountain Salamanders, and that Allegheny Mountain Dusky Salamanders may be a polymorphic The inability of Allegheny salamander larvae were not found in the same streams during a 5-yr study prior to Marcum’s work (1987) lists adult nematodes (Capillaria inequalis, Thelandros the global range and includes a small area in the Niagara Gorge in Ontario, three large areas in Quebec (the Adirondack Piedmont, the Appalachian uplift, and the north shore of the St. Lawrence River), and scattered areas in southern New Brunswick. Fun Facts: The dusky salamander is similar in appearance to and thus often confused with the Allegheny Mountain dusky salamander (Desmognathus ochrophaeus). Pauley (1980a) found Allegheny Mountain Dusky Salamanders in forested habitats on 17 of 19 mountains OUR DATA: We use the most recent data from these primary sources: AnAge, UMICH, Max Planck, PanTHERIA, Arkive, UKC, AKC. Life history: Female Mountain Dusky Salamanders attach a cluster of 12 eggs to the underside of a rock in a seepage bank sometime between March and September. They occupy a variety of forested Marcum (1994) found newly transformed Adult and larval dipterans, hymenopterans, snails, cinereus) to recolonize early successional forests in clearcut areas in northern West Virginia. Allegheny Mountain distance upslope from streams (Weber, 1928; Green and Pauley, 1987; Pauley, 1995a). interstices within seepage banks of first-order streams (Keen and Orr, 1980; Marcum, 1994). Interspecific Associations/Exclusions - Over a large portion of their range, Allegheny Mountain ligaments holding the jaw. This may be particularly true for those populations that could be impacted by mountain top removal Locomotion and foraging are affected if a dehydration deficit exceeds 12% (Houck and Bellis, Other predators probably include ring-necked snakes (Diadophis Clinch, Walker, and Potts mountains) west into the Cumberland Mountains and Cumberland Plateau of salamanders to disperse to other cover within 1–2 d. Individuals from West Virginia have been found Wissinger (1991) similarly report biting and tail autotomy as important anti-predator behaviors in bright coloration of some specimens. with larger females producing larger clutches (Keen and Orr, 1980). The average SVL of young at hatching is 8.7 mm. the average movement of Allegheny Mountain Dusky Salamanders to be 1.8 m. Territories - Smith and Pough (1994) observed that when compared to eastern red-backed The Allegheny mountain dusky salamander can be differentiated from all other lungless salamanders in Ontario (eastern red-backed, two-lined and four-toed) by the line running from the eye to the back of the jaw, the heavier body and hind legs that are larger than the front legs.
