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...

Let the winter sun shine on, let me feel the frost of dawn: Rangifer tarandus osteology, anatomy, and identity
DownloadFall 2020
Rangifer tarandus, the species which encompasses both caribou in North America and reindeer in Eurasia, is a keystone species for both the cultures and the ecosystems of the circumpolar world. Because of this, human interactions with reindeer and caribou throughout history are of great interest...

Paquet, P.C., Hik, D.S., Frame, P.F., Cluff, H.D.
Wolves (Canis lupus) on the Canadian barrens are intimately linked to migrating herds of barren-ground caribou (Rangifer tarandus). We deployed a Global Positioning System (GPS) radio collar on an adult female wolf to record her movements in response to changing caribou densities near her den...

Measuring wildlife response to seismic lines to inform land use planning decisions in northwest Canada
DownloadFall 2012
Development of hydrocarbon resources across northwest Canada has spurred economic prosperity but also generated concerns over impacts to biodiversity. To balance these interests, comprehensive land use plans have been used to match targeted management strategies to ecological components deemed...

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
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...

Polar Bear (Ursus maritimus) Habitat, Space Use,and Movements in a Seasonal Sea Ice Ecoregion
DownloadFall 2015
Polar bears (Ursus maritimus) are sea ice habitat specialists and climate change has affected sea ice throughout this species’ circumpolar range. The annual phenological cycle of sea ice growth and decay is a strong influence on polar bear distribution and ecology. Study of the habitat selection,...
