Sea ice in Hudson Bay is melting earlier and freezing later as the climate warms, resulting in declines in the condition, survival, and population size of polar bears (Ursus maritimus) in the Western Hudson Bay population. The objectives of this study are to analyze temporal variation in...

Malenfant, René M.

Polar bears (Ursus maritimus) were among the first large mammals to be assessed for genetic variation in the wild, and they remain a common subject of genetics studies. Although recent advances in genotyping technology have allowed for more accurate determination of population structure and the...

Traditionally, population delineation has been determined using mark-recapture, band returns, and more recently, telemetry, geologgers and genetics. But telemetric and genetic population structure data have rarely been examined concurrently to explore differences and similarities. I define a...

Stirling, I., Derocher, A.E.

If climatic warming occurs, the first impacts on polar bears (Ursus maritirnus) will be felt at the southern limits of their distribution, such as in James and Hudson bays, where the whole population is already forced to fast for approximately four months when the sea ice melts during the summer....

Projections of polar bear (Ursus maritimus) sea ice habitat distribution in the polar basin during the 21st century were developed to understand the consequences of anticipated sea ice reductions on polar bear populations. We used location data from satellite-collared polar bears and...

It is estimated that over 1.1 million people in Canada will have dementia by 2038 (Alzheimer Society of Canada, 2010). In the caregiving context it is important that independence be maintained for as long as possible. Previous research has shown that caregivers can inadvertently create excess...

Whether the invasive freshwater cladoceran Bythotrephes longimanus can establish after introduction into a water body depends on several biotic and abiotic factors. Among these, water temperature is important because both development rates and mode of reproduction (parthenogenetic or sexual) in...

Mating systems evolve in response to factors that influence the distribution and availability of mates. In turn mating systems can influence species life histories as a result of sexual selection. Most of what is known about sexual selection in large mammals comes from long-term studies of...

SSHRC Awarded IG 2014: How do humans recognize speech? How do factors such as native language, age, and dialect have an effect on the way in which spoken words are recognized? The present proposal seeks to investigate these and other questions regarding spoken language recognition by creating and...
