Polar Bear Distribution and Habitat Resource Selection Data, Beaufort and Chukchi Seas, 1985-2016
July 29, 2019
These data from satellite radio-collared adult female polar bears captured in the southern Beaufort Sea, 1985-2016 were used for testing the regional, seasonal and decadal efficacy of retrospective polar bear resource selection functions (RSF) developed for the Arctic basin and its peripheral seas (see Durner et al. 2009). The data includes the following: 1) a csv file of locations used to build a 99% minimum convex polygon study area; 2) a csv file of locations, that occurred within the study area, and were used to test RSFs; 3) a csv file of locations used to build seasonal kernel utilization distributions (95% and 50% contours) for periods 1985-1995, 1996-2006, and 2007-2016.

Are polar bear habitat resource selection functions developed from 1985-1996 data still useful?
1. Greenhouse gas-induced warming in the Arctic has caused declines in sea ice extent and changed its composition, raising concerns by all circumpolar nations for polar bear conservation.
2. Negative impacts have been observed in three well-studied polar bear subpopulations. Most subpopulations, however, receive little or no direct monitoring, hence, resource selection functions (RSF) may provide
