ICE ecocystems: Polar bear
Decreasing sea ice is leaving more bears stranded on shore during the summer months. ICE Polar bear will explore the body condition and reproductive status of polar bears in relation to changing physical conditions. Special attention will be paid to where bears den over the next few years.
The specific primary hypotheses to be addressed will be: female polar bears stranded on land will have lower condition, lower reproductive success (higher offspring mortality), smaller ranges and less dependence on marine food.
