To allow gas exchange, the skin needs to remain moist at all times; yet it is ineffective in restricting water loss by evaporation (Spight 1967, 1968, Spotila 1972, Spotila and Berman 1976, Feder and Burggren 1985). The New Brunswick Fish and Wildlife Act prohibits taking any wildlife into captivity, keeping wildlife in captivity, or selling, trading or purchasing any wildlife, without authorization from the Minister. Artificial dams created along urbanized streams may also reduce salamander abundance through increased predation by fish (Lowe and Bolger 2002, Lowe et al. Le Naturaliste Canadien 128(1): 61-67. The Leadback variation is light gray to black and lacks the stripe. It arose from the need for a single, official, scientifically sound, national listing of wildlife species at risk. Evidence against a role for experience in the maintenance of sexual incompatibility between sympatric salamanders. BONIN, J. Dartmouth College, Hanover, New Hampshire, USA. Feeding habits of seepage-dwelling dusky salamanders (Desmognathus fuscus) of Short Mountain, Cannon County, Tennessee. Is the total population severely fragmented? New Brunswick Museum. DESROCHES, J.-F. and I. PICARD. V + 20 pp. 1988, Sharbel et al. Numerous field surveys also took place on seven Monteregian Hills between 1997 and 2004 (Ouellet et al. Nonetheless, the species is protected by the provincial Act respecting conservation and development of wildlife (R.S.Q., c. C-61.1) that prohibits collecting, buying, selling or keeping specimens in captivity. 2009). On the other hand, some populations seem to have disappeared. Considerable search effort was expended around Quebec City, after the species’ presence was confirmed in 1987. Electrophoretic variation in Appalachian populations of the Desmognathus fuscus complex (Amphibia: Plethodontidae). Within its range, the Northern Dusky Salamander occurs discontinuously usually in high elevation, low-order streams, in forested habitat. Her thesis focused on determining the habitat selection of a community of stream salamanders from Covey Hill (Quebec) comprising five species and Desmognathus fuscus x D. ochrophaeus hybrids. Response to impact of timber harvesting on salamanders. Ecology 57: 238-251. The tail makes up about half the total length of this salamander. Herpetologica 46: 415-422. JUTERBOCK, J. E. 1990. 1995. Habitat:  Rocky lakeshores, brooks, sandy/silty streams, springs or seeps. Funding provided by the Canadian Wildlife Service, Environment Canada, supported the preparation of this status report. Clear rocky streams, intermittent streams, seeps and semi-dry brooks. Ontario Ministry of Natural Resources. In Ontario, the species is considered rare because of its very restricted range. Eggs are spherical and opaque, between 2.7 and 5 mm in diameter. The geographic distribution of southern dusky salamanders (Desmognathus auriculatus) has been mapped according to museum records and the literature (Means, 1999a). 2004, Ouellet et al. Second edition. Eggs are laid in cryptic microhabitats adjacent to streams, between 1 and 88 cm from the water’s edge (n=85) (Petranka 1998, Snodgrass et al. Phylogenetic analysis of ecomorphological divergence, community structure, and diversification rates in dusky salamanders (Plethodontidae: Desmognathus). 2006). The species’ presence in some localities in Quebec and New Brunswick has not been confirmed in the last 20 to 50 years. Juveniles have round yellow spots that fade with age. SHANNON, C. B. Still, very limited data are available on local abundances. The species uses subterranean retreats or burrows near the streams edge as well as leaf litter, logs, rocks and moss as a source of protective cover for avoiding desiccation and predators. Institute of freshwater Research, Drottingholm 34: 133-148. (70); Frenette 2007 (72). October 2010. Herpetologica 43: 361-368. Does Niche Conservatism Promote Speciation? Survival of larval Spring Salamanders is reduced by over 50% in the presence of fingerling Brook Trout (Resetarits 1995). These forms, similar to the Spring Salamander (Gyrinophilus porphyriticus), can be discriminated by the absence of reticulations on their body (Desroches and Rodrigue 2004). The range of northern dusky salamanders is as described above. Other than Markle (2006) and Markle et al. Caractérisation de l'habitat d'une communauté de salamandres de ruisseaux comportant des hybrides. One population has disappeared (i.e., Mount Saint-Hilaire, QC) and the persistence of two other populations is doubtful (Mount Brome and Mount Yamaska); perhaps a decline in number of populations is possible. Of these, nearly 350 are in Covey Hill and 40 on the north shore of the St. Lawrence (AARQ 2010, CDPNQ 2010, A. Boutin unpublished data). Ecology 52: 632-637. Status of amphibians and reptiles of Fundy National Park and its greater ecosystem. 2008). Journal of Herpetology 6: 144-146. 2006. Extinct (X)A wildlife species that no longer exists. The Ontario population is within an unexploited forest stand managed by the Ontario Parks Commission (Yagi and Tervo 2008). Therefore, it is hard to compare populations or to make assumptions on local densities.
