Research Scientist

(Biography) I am a research scientist with the Ontario Ministry of Natural Resources and an Adjunct Professor in the Environmental and Life Sciences program at Trent University in Peterborough, Ontario. Current research interests include the ecology and demography of the Southern Hudson Bay polar bear population, one of the most southerly polar bear populations in the world. I am interested in how future changes in sea ice distribution and duration will affect abundance and distribution of bears in this population. With colleagues I have looked at how body condition of individual bears has changed since the mid-1980s, and have worked to develop physiological indicators of chronic stress that might be used to monitor health of polar bears and other wildlife species. Another aspect of our research involves deploying GPS/satellite radiocollars on adult females to intensively monitor their on-ice movement patterns. We hope this detailed information will help us to better understand how seasonal movement patterns, dispersal, and distribution of the bears will be affected by climate change.
