Population genomics reveals genetic variation in grizzly bears across coastal and interior habitats, indicating potential for local adaptation.

Genetic separation exists between grizzly bear populations from coastal and interior regions, supporting adaptation.
Whole-genome resequencing characterized 3.9 million SNPs in 31 grizzly bears, revealing geographic groupings.
Significant differentiation supports an isolation-by-distance model, reflecting travel across ecological boundaries.
Identified genomic regions may inform conservation strategies for grizzly bears facing climate change.

Henson et al. (2025) studied this question.
