Abstract The Wolverine (Gulo gulo) is a cold-adapted species of conservation interest because it sensitive to human development, disturbance, exploitation, and climate warming. populations have been studied across much their distributional range evaluate patterns genetic diversity, structure, gene flow. Little population structure has detected in northwestern North America with microsatellite loci, but low genomic diversity wolverines may limit detection differences this highly vagile species. Here, we genotyped relatively large sample from Alaska (US) adjacent Yukon (Canada) 12 loci (n = 501) 4,222 single nucleotide polymorphisms (SNPs; n 201) identified using restriction-site associated DNA sequencing. We compared the relative ability our SNP datasets differentiation, isolation by distance (IBD). predicted that dataset would detect higher degree provide more significant support for IBD. found evidence multiple clusters, including distinctiveness southeast on Kenai Peninsula. additional clusters align largely ecoregions, showed stronger IBD, while 2 were generally consistent estimates differentiation among regional groups. Our results highlight importance methods assess flow wolverines. Identifying allows an assessment potential impacts threats important precursor designing monitoring programs.
