Fall 2013
Polar bears (Ursus maritimus, Nanuut) are a culturally and economically important species to the Inuvialuit. As a result of climate change, the Arctic is experiencing rapid ecological changes with the potential for profound impacts on polar bear populations. The objectives of the thesis were to...

Mitigating the Effects of Human Activity on Grizzly Bears (Ursus arctos) in Southwestern Alberta.
DownloadSpring 2015
Anthropogenic habitat loss and alteration, as well as human-caused mortalities associated with increasing access, threaten grizzly bear populations across much of their North American range. This research investigates strategies for mitigating the negative effects of human activities on grizzly...

Fall 2012
Sea ice concentration (SIC), the length of the ice-free period, and the break-up date are correlated with the survival and reproduction success of polar bears (Ursus maritimus) in Western Hudson Bay (WH). I use a high-resolution sea ice-ocean model to predict these parameters through the 21st...

Spring 2015
West-central, Alberta is subject to a growing number of resource extraction activities such as forestry that change ecosystem components and their structure. This area is important for the grizzly bear (Ursus arctos horribilis) population, which is considered to be a threatened species in Alberta...

Spring 2015
Polar bears (Ursus maritimus) are an apex predator of the Arctic marine food web and vulnerable to changes in sea ice because various aspects of their existence depend on this dynamic platform. Arctic sea ice extent and thickness have declined, and been particularly low since the first record...

Spring 2015
Polar bears (Ursus maritimus) enter a period of intensified feeding in the spring, which allows for the accumulation of energy stores critical to surviving the open water season. Study on polar bear predation has been limited by sample size and spatial extent, and hypotheses on the demographic...
