Polar bear (Ursus maritimus) foraging, spatial, and energetics ecology in the changing Arctic
DownloadFall 2020
Climate warming in the Arctic has resulted in rapid and extensive changes to sea ice dynamics and profound ecological impacts, including changes to the timing of life history events, community structure, and food web dynamics. Sea ice-dependent species such as polar bears (Ursus maritimus) are...

Fall 2011
Understanding how populations are structured and how they use natural and anthropogenic spaces is essential for effective wildlife management. A total of 510 barren-ground (Rangifer tarandus groenlandicus), 176 boreal (R. t. caribou), 11 mountain woodland (R. t. caribou), and 39 island (R. t....

Walking in Their Footsteps: New Approaches to Identify Behavioural Processes and Define Home Ranges Using Animal Movement Data
DownloadFall 2014
Animal movement and space-use patterns influence the distribution and abundance of species, predator-prey interactions, and many other ecological processes. Different approaches are used to study individual's space-use strategies and each approach suffers from unique challenges. The mechanistic...
