Adjusting values for either average age of first reproduction or maximum longevity did not appreciably influence the average age of the breeding female because either very old individuals or younger breeders were being removed. Ryan, C. 1981. Servheen, C. 1999a. Website accessed August 1, 2011: http://www.environmentyukon.gov.yk.ca/huntingtrapping/biggame.php#grizzly. 2002; Boulanger et al. Caughley, G., and A.R.E. Additionally, the attractants usually associated with human homes (refuse, pet food, livestock) dictate that bears with home ranges overlapping permanent human habitation are at elevated risk of mortality (McLellan 1994; Ciarniello et al. Grizzly bear population abundance, distribution, and connectivity across British Columbia's southern Coast Ranges. B.C. The Western Grizzly Bear DU numbers approximately 26,000 bears (Table 4). Ursus arctos. McLoughlin, P.D., Case, R.L., Gau, R.J., Cluff, H.D., Mulders, R., and Messier, F. 2002a. Martin, P.L. 1996. Alberta Sustainable Resource Development. Nagy, J.A. In east-central Alaska, each adult male Grizzly Bear killed 3.3–3.9 adult Moose annually, whereas each lone adult female killed 0.6–0.8 adult Moose per year (Boertje et al. 105pp. Mountain goat recruitment: kid production and survival to breeding age. Spiess, Arthur. 2006). Ursus 15:1-9.

Committee on the Status of Endangered Wildlife in Canada. 1997. 72 pp. Further evidence about the barren-ground grizzly bear in northeast Labrador. Connectivity of small areas of suitable habitat is likely necessary for continued occupancy by Grizzly Bears (e.g., Proctor et al. Assistant Director of Wildlife, Department of Environment Government of Nunavut, P.O. Estimating population growth of grizzly bears from the Flathead River drainage using computer simulations of reproduction and survival rates. [Zoologische Garten, 1877:135-136. This warming may improve bear habitat in the north and allow the species to expand its range, for example into the Canadian Arctic Archipelago (although evidence of recent expansion of Grizzly Bear range into northern NT, Nunavut, and Manitoba, has yet to be quantitatively tied to climate change). Wildlife Inventory Section, Resources Inventory Branch, Ministry of Environment, Lands and Parks, P.O. Pages 121-136 in D.F. Grizzly bears have male-biased dispersal, with subadult male Grizzly Bears usually dispersing upon independence, whereas subadult females are commonly more philopatric (LeFranc et al. 1999b). Fain, J.A. Comparison of results regarding resource selection models for female grizzly bears in the eastern slopes based on coarse-filter and fine-filter approaches. Rates were estimated using various methods. Pages 15-25 in M. Taylor, ed. 2005), Hoary Marmots (Barash 1989), Mountain Goats (Oreamnos americanus; Festa-Bianchet et al. Caribou (both calves and adults) was the most prevalent food item, especially in spring, mid-summer, and autumn. 1987, 1997), and mark-recapture techniques that include camera traps, wherein bears trip cameras and photograph themselves (Mace et al. Turner writes at length about the latter species, including aspects of its biology and relationship with the Innu. 1998, 2005). 1997. They can be found from sea level to high-elevation alpine environments. Elton, C.S. Apps, C.D., B.N. A conservation biology approach to management of grizzly bears in Banff National Park, Alberta. Grizzly bear habitat. 2002. Who killed Mary? Inuit land use and occupancy project. Most northerly observation of a grizzly bear (Ursus arctos) in Canada: photographic and DNA evidence from Melville Island, Northwest Territories. Image copyright iStockphoto / PaulTessier. The ecology of barren-ground grizzly bears in Nunavut. Grizzly bears are best distinguished from black bears by morphological traits; grizzly bears are generally much larger than black bears, and have a pronounced shoulder hump and flat dish-shaped face. For example, Grizzly Bears in central coastal BC roamed widely during the berry season, using 10 berry species in divergent habitats (Hamilton and Bunnell 1987). Population dynamics of moose in south-central Alaska. Reynolds, E.R. Miller, C.R., L.P. Waits, and P. Joyce. Lethbridge, Alberta. Canadian Journal of Remote Sensing 35: 23-36. Arctic Climate Impact Assessment. Journal of Wildlife Management 65:92-99. Maraj, R. 2010. 55 pp. Late-Quaternary biogeographic scenarios for the brown bear (Ursus arctos), a wild mammal model species. Whereas these remnant populations represent critical areas of focus for Grizzly Bear conservation and management efforts, there is no evidence for unique ecological settings that have given rise to local adaptations, thus these fragmented populations do not warrant DU status. 2001b. Effect of spatial differences in habitat on home ranges of barren-ground grizzly bears. and F.W. 1999) and population persistence (Apps et al. This may be due to the longer growing seasons experienced in the Arctic in recent years (Arctic Climate Impact Assessment 2004), although this hypothesis has not been tested. Arthur, and C. Servheen. Looking at the above Map of Grizzly Bear Habitat, you can see that Grizzly Bears are most common in Northern Canada, Alaska, and a small part of the Northern USA. Effect of hibernation and reproductive status on body mass and condition of coastal brown bears. Human activity is believed to lead to fragmentation and isolation of demographic units, whereby population dynamics may become determined by stochasticity in survival and reproduction irrespective of other factors, increasing chances of local extinction.
