Denning ecology of barren-ground wolves in the central Canadian Arctic.
My study focused on investigating wolf-caribou dynamics on the summer range of the Bathurst caribou herd. I used a multi-scale study design to investigate the behavioural and population responses of wolves during a severe decline in caribou numbers. The summer ranges of the Bathurst herd contracted...
