This report presents results of the first of a two-year investigation of the influence of caribou distribution on wolf predation behavior in late winter. This study was part of a larger ongoing study of wolves in Gates of the Arctic National Park and Preserve. Prey selection and kill rates were quantified for each of four wolf packs for periods ranging from 24 to 27 days during a 30-day monitoring period. In 1989, 84 kills were investigated via helicopter within 2-10 days of being observed. Specimens were collected from 52 kills. Measurements of bone marrow fat content, bone weight, and bone length were analyzed, and teeth were sent to a lab for aging.
