Prey specialization may influence patterns of gene flow in wolves of the Canadian Northwest
Abstract This study characterizes population genetic structure among grey wolves ( Canis lupus ) in northwestern Canada, and discusses potential physical and biological determinants of this structure. Four hundred and ninety‐one grey wolves, from nine regions in the Yukon, Northwest Territories and...
