TL;DR: In this article, DNA hair-trap sampling was applied to evaluate relationships of grizzly bear detections with landscape variables of habitat and human activity, and to model the spatial distribution and abundance of bears.

TL;DR: It is concluded that apparent competition can cause rapid population declines and even extinction where changes in species composition occur following large scale habitat change.

TL;DR: This paper studied the current state and potential causes of fragmentation in grizzly bears over approximately 1,000,000 km 2 of western Canada, the northern United States (US), and southeast Alaska.

TL;DR: The results confirm the close association of mountain caribou with old-growth forests, and describe relationships that can be accounted for in spatially explicit habitat-timber supply forecast models.

TL;DR: Grizzly bears (Ursus arctos) occur across British Columbia and in Alberta in mostly forested, mountainous, and boreal ecosystems as mentioned in this paper and have been used to explore a suite of ecological questions of grizzly bears in western Canada.
