Species that will experience the effects of climate change the most are ones that depend on sea ice for survival. As the quantity and quality of sea ice changes and the time gap between the spring thaw and fall formation increases, animals like polar bears are struggling to find adequate high fat prey in the form of ringed seals, which are necessary for the bears to survive the winter. Field biologist turned Director of Conservation and Research at the Assiniboine Park Zoo, Dr. Stephen Petersen discusses polar bear physiology, life history, public education and policy, and the resulting conflicts against the backdrop of a changing arctic habitat and ecosystem. The clear message is that one size does not fit all when it comes to population management strategies for this species as various segments of the bear population react differently depending on their latitude and proximity to humans.
