Home range size estimates are often used to assess the amount of space required for animals to perform the activities essential for their survival and reproduction. However, in moving environments, traditional home range estimates may be ill suited to this task. In particular, traditional home...

Sea ice concentration (SIC), the length of the ice-free period, and the break-up date are correlated with the survival and reproduction success of polar bears (Ursus maritimus) in Western Hudson Bay (WH). I use a high-resolution sea ice-ocean model to predict these parameters through the 21st...
