Assessing stress in western Hudson Bay polar bears using hair cortisol concentration as a biomarker
DownloadFall 2015
The development of novel biomarkers to help assess whether polar bear (Ursus maritimus) health is impacted by long-term physiological stress associated with climate change represents an emerging area of research. With progressively greater reductions in sea ice cover and a corresponding decrease...

Dall sheep (Ovis dalli dalli), grizzly bear (Ursus arctos) and wolf (Canis lupus) interactions in the Northern Richardson Mountains, Canada

Lambert Koizumi, Catherine M S
Assessing the impact of predators on a prey population is inherently challenging, a fortiori in remote ecosystems. With this thesis, I studied the interactions between a recently declining Dall sheep (Ovis dalli dalli) population and two predators: grizzly bears (Ursus arctos) and wolves (Canis...

Evaluation of Highway Mitigation on the Frequency of Wildlife-Vehicle Collisions on the Highway and an Adjacent Railway in a Montane Ecosystem
DownloadFall 2016
Transportation networks are expanding rapidly to meet increasing global demands to move people and cargo. These networks are essential to connect societies and economies but have several negative effects on wildlife populations including collisions with vehicles. Growing incidences and increasing...

The Mackenzie Delta region, NWT, has a short growing season and highly seasonal climate, and brown bears (Ursus arctos) there face many challenges obtaining their nutritional requirements. Consumption of meat by brown bears is linked to increases in population density, fecundity, growth and body...

Human-wildlife conflicts are a global conservation challenge. Reserves and protected areas usually do not adequately provide for the space needs of large carnivores, resulting in overlap between carnivore home ranges and private lands. Private lands often can provide valuable habitats, but...

A major side-effect of industrial activity is the associated linear-feature footprint and increase in recreational access. Alberta’s threatened grizzly bear (Ursus arctos) populations overlap with a multitude of different potential forms of human disturbance, including human recreational...

Individual and Seasonal Variation in Grizzly Bear Selection for a Railway and other Linear Features in Banff National Park, Canada
DownloadFall 2016
Mortality caused by collisions with trains affects numerous species globally and has increased recently to threaten the grizzly bear (Ursus arctos) population protected in Banff and Yoho National Parks, Canada. Although train collisions are the ultimate cause of mortality, the more proximate...

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 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...
