Genetic structure of North American wolverine ( Gulo gulo) populations
Abstract Wolverines ( Gulo gulo ) are found in low densities throughout their circumpolar distribution. They are also potentially susceptible to human‐caused population fragmentation (development, recreation and fur harvesting). The combination of these factors has contributed to this species being...

Abstract Wolverines ( Gulo gulo ) are found in low densities throughout their circumpolar distribution.

The effects of inherently low densities and anthropogenic pressures on the genetic structure and variation of wolverine populations are, as yet, unknown. In this study, 461 individuals were typed at 12 microsatellite loci to investigate the population genetic structure of wolverines from north‐western Alaska to eastern Manitoba.
