Grizzly bear population genomics across a coastal-interior ecotone in British Columbia, Canada.

ABSTRACT: Local adaptation research often focuses on discrete populations without extensive gene flow that are under differential selective pressures. By contrast, grizzly bears Ursus arctos in British Columbia (BC) are wide-ranging omnivores that span an environmental and resource ecotone from the coastal, salmon-enriched rainforest to dry interior plateau. This ecotone has been associated with local adaptation in other species and the different regions to morphological variation in grizzly bears. To understand genome-wide population genetic patterns across the ecotone and to identify loci or genomic regions associated with these different environments, here we use whole-genome resequencing to characterize 3.9 M SNPs in 31 grizzly bears spanning from central to northern latitudes in coastal and int
