The circumboreal wolverine (Gulo gulo sp.) is ideal for studying responses to environmental perturbation in the North due to a history of persistence in glacial refugia and subsequent glacial recolonization. Wolverines are also excellent indicators of human influence on the environment due to their close association with remote areas and cold, snowy climes. Through the use of genetic tools (i.e., nuclear microsatellite loci and mitochondrial sequences), I examined population structure of wolverines in Alaska and western Canada to identify signatures of glacial refugia, bottlenecks, and distinctive populations, sex-biased dispersal, gene flow, and source and sink population dynamics. I identified genetic …
