Therefore, any major developments along the adjacent uplands could be detrimental, as they would change the quality and quantity of water discharged in the area. The species is considered a feeding generalist that consumes available prey of an adequate size (Burton 1976, Sites 1978). 1983, Waters 1995, Shannon 2000). 2004. A. CRAWFORD and R. D. SEMLITSCH.

Populations in Quebec east of the St. Lawrence and in New Brunswick are undoubtedly connected through the New England states and, as such, they are considered a single designatable unit (Figures 4, 5, 6). Probability of extinction in the wild is at least 20% within 20 years. BERTACCHI, W. 2011. It successfully displaces D. fuscus toward dryer, less optimal microhabitats (Grover 2000).In return, D. fuscus is able to displace the Red-backed Salamander (Plethodon cinereus) and D. ochrophaeus toward drier habitats (Krysik 1979, Grover and Wilbur 2002). 1993). BANK, M. S., J. R. BURGESS, D. C. EVERS and C. S. LOFTIN. Males sexually mature in the second year, Females often first reproduce in the third year. Maximum life span is about 10 years.

Map showing the global range (dark grey area) of the Northern Dusky Salamander in eastern North America. The species is also found along the south shore of the St. Lawrence River between the Chaudière River mouth (Charny) and Saint-Aubert, past Montmagny, which represents the northernmost record of the Northern Dusky Salamander in Canada. Larvae hatch in 3 to 5 weeks and migrate to terrestrial habitat after approximately 2 months. Hatching occurs in late summer and early fall, (Bishop 1941, Organ 1961, Juterbock 1986, Hom 1987, Petranka 1998). Committee on the Status of Endangered Wildlife in Canada. Would immigrants be adapted to survive in Canada? Journal of Morphology 122: 265-306.

As body weight is directly correlated with clutch size, deforestation can have negative outcomes on reproductive success and survivorship. Because a single catastrophic event could wipe out the entire Ontario population, it should be regarded as a single location. On either side of the stripe there are two thin black stripes that start at the eye and extend the length of their bodies. To limit desiccation D. fuscus remains in refuges and reduces daily activities to periods of high moisture and low temperatures (Hairston 1949, Spotila 1972, Huheey and Brandon 1973, Shealy 1975, Grover 2000).

It forages along the streamside, mostly in terrestrial habitat. Considering the first breeding occurs at an average age of 4 years, and that the oldest breeding individuals in the wild can reach 10 years (Danstedt 1975, Desroches and Rodrigue 2004), generation time for the Northern Dusky Salamander could be about 6-7 years. Assessment of Species Diversity in the Atlantic Maritime Ecozone, NCR Research Press, Ottawa, Canada. 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.

These lines fade as the salamanders age. Because the species has only been discovered recently in Ontario, little is known about fluctuations and trends of the population. In Quebec, backcrosses seem to occur exclusively with D. ochrophaeus (Sharbel et al. A. and S. I. GUTTMAN. Journal of Herpetology 22: 247-249. The Northern Dusky Salamander winters in habitats protected from freezing, either on the stream bottom or buried in refuges with gravel substrate and continuous water flow (Ashton 1975, Ashton and Ashton 1978, Desroches and Rodrigue 2004). Stream salamanders are particularly sensitive to large-scale (i.e., landscape) habitat alterations that change spatial configuration of stream networks and reduce their connectivity (Welsh and Ollivier 1998, Lowe and Bolger 2002, Grant et al. This can expose larvae to stronger currents, and decrease prey availability (Smith and Grossman 2003). D. fuscus localitiesfrom Mount Megantic, Notre-Dame-des-Bois and Lake Megantic are on public land where these silvicultural measures apply. Description: 2.5 to 5 inches long head to tail. In Canada, D. fuscus occurs in a small area of the Niagara Gorge (Ontario), in the Covey Hill area (Quebec), throughout the outskirts of the Appalachian Mountains of southern Quebec and southern New Brunswick, and along the west/north shore of the St. Lawrence (Figure 4).

This revision is the first since the list was written in the 1970’s, with the help of the Massachusetts Herpetological Society. Senior Environment Specialist, Ontario Power Generation Inc., Niagara-on-the-Lake, Ontario. One of the most adverse effects of timber harvesting is the filling-in of the interstitial spaces used by salamanders for foraging, shelter, nesting, and overwintering through substrate embedment (siltation) (Hawkins et al.

At the federal level, the Northern Dusky Salamander was assessed as a single DU and Not at Risk by COSEWIC (1999). Dispersal of stream salamanders occurs primarily along the stream channel (within-network movement) following a model of simple diffusion (Lowe 2003, Lowe et al.

Variation in larval growth and metamorphosis in the salamander Desmognathus fuscus. In New Brunswick, many historical records exist on D. fuscus (reviewed by McAlpine 1997) of which two sites were confirmed in recent years. 2003. A certificate of authorization from the minister must be obtained prior to undertaking any construction or industrial activity that negatively affects a river, a lake, a pond, a marsh, or a peat bog. At the landscape scale, connectivity between aquatic habitats is important to maintain dispersal and gene flow (Schalk and Luhring 2010); restricted movements between streams may cause population isolation (Tilley and Scherdtfeger 1981). The Adirondack foothills and areas near Quebec City were more thoroughly studied in the following years (Bonin 1991, Bider and Matte 1994). Role of temperature and water in the ecology of lungless salamanders. Larval development requires cool flowing water and may be affected by stream dessication and acidification (Green and Peloquin 2008). As retreats are depleted, competition and predation pressures may increase and cause community shifts (Krzysik 1979, Southerland 1986 a, b, c, Roudebush and Taylor 1987).Furthermore, D. fuscus avoids nesting in streams receiving runoff from residential areas as they likely suffer more erosion(Snodgrass et al. 2006. 2010). The Appalachian seal salamander has a robust body similar to its cousin, the northern dusky salamander. FITZGERALD, W. F., G. M. VANDAL and R. P. MASON. GALOIS, P. and M. OUELLET. Over 90 new occurrences of D. fuscus were found and the species’ persistence was confirmed in known sites (C. Laurendeau, pers. Vegetation cover keeps water cool, well oxygenated, and maintains moisture and temperature levels adequate for salamander survival (Shealy 1975, Krzysik 1979).

D. fuscus is known to have lower occupancy probabilities in streams within urbanized regions compared to relatively undeveloped areas (Grant et al. Water pollution can affect the species through underground water and connecting streams and is a threat throughout the Canadian range. In 2010, habitat was searched along the eastern limit of the species’ range as well as near Portneuf on the north shore of the St. Lawrence (C. Laurendeau, pers. Herpetologica 33: 1109-1034. Giasson, Pascal – Gestionnaire, Programme des espèces en peril, Direction de la faune et des poisons, Ministère des Ressources naturelles et de l'Énergie, Fredericton, New Brunswick. 2005, Appendix 2A). Larvae from eggs that overwinter grow larger before hatching, emerging at a full inch long. The Redback phase has a broad, straight stripe from it’s head, tapering at the tip of the tail. Local and regional differentiation has also been suggested by significant differences in life history, phenotype, and body size throughout the species’ range (Danstedt 1975, 1979, Davic 1983, Tilley 1988, Jutterbock 1990).
