Genetic homogeneity of Canadian mainland marten populations underscores the distinctiveness of Newfoundland pine martens ( Martes americana atrata )
American pine martens (Martes americana) are mid-sized mustelids found in the boreal and taiga zones of North America that prefer late-successional coniferous forests. Studies have shown that tracts of treeless land and roads may impede marten dispersal and that fewer martens are captured or observe...

American pine martens (Martes americana) are mid-sized mustelids found in the boreal and taiga zones of North America that prefer late-successional coniferous forests.

If marten habitat is indeed fragmented by roads and treeless land, this may result in decreased gene flow between regions and therefore in increased levels of genetic structure and decreased genetic variation in regions where these potential barriers are present. In this study, we evaluate the genetic variation and connectivity of marten populations across Canada.
