Ecological factors drive differentiation in wolves from British Columbia
Abstract Aim Limited population structure is predicted for vagile, generalist species, such as the grey wolf ( Canis lupus L.). Our aims were to study how genetic variability of grey wolves was distributed in an area comprising different habitats that lay within the potential dispersal range of an i...
