Determining causes of genetic isolation in a large carnivore (Ursus americanus) population to direct contemporary conservation measures. [PDF]

PLoS One, 2017
The processes leading to genetic isolation influence a population’s local extinction risk, and should thus be identified before conservation actions are implemented. Natural or human-induced circumstances can result in historical or contemporary barriers
