The ecology of polar bears in relation to sea ice dynamics

Seth G. Cherry
2011
Recent research indicates climate change will be amplified in Polar Regions, which will cause decreases to sea ice thickness and extent throughout the Arctic. Polar bears (Ursus maritimus) will be directly affected by changes to Arctic sea ice conditions because they rely on the ice substrate for numerous aspects of their life history. Perhaps of most importance, polar bears use the sea ice platform to access their main prey, pagophilic seals. Determining specific I would like to thank my

He was an incredibly supportive mentor and I am grateful to have had the opportunity to work with him. I would also like to thank the rest of my supervisory committee (Drs. Ian Stirling, Keith Hobson, Erin Bayne, and David Schindler) for their time and assistance. In addition, I thank other members of the Derocher Lab (past and present) and numerous graduate students and colleagues from the Department of Biological Sciences for their help and advice.
