Density and genetic diversity of grizzly bears at the northern edge of their distribution ...
Species at the periphery of their range are typically limited in density by lower habitat quality. As a result, the Central-Marginal Hypothesis (CMH) predicts a decline in genetic diversity of populations towards the periphery of a species' range. Grizzly bears ( Ursus arctos ) once ranged thro...

Species at the periphery of their range are typically limited in density by lower habitat quality. As a result, the Central-Marginal Hypothesis (CMH) predicts a decline in genetic diversity of populations towards the periphery of a species' range. Grizzly bears ( Ursus arctos ) once ranged throughout most of North America but have been extirpated from nearly half of their former range, mainly in the south. They are considered a species at risk even in Canada's remote North, where they occupy the northernmost edge of the species' continental distribution in a low-productivity tundra environment. With climate change, one of their main food items in the tundra (caribou), which has always shown yearly fluctuations, is declining, but simultaneously, grizzlies appear to be expanding their range northward, in tundra environment.
