Early-winter diet of woodland caribou in relation to snow accumulation, Selkirk Mountains, British Columbia, Canada
Woodland caribou (Rangifer tarandus caribou) in the southern Selkirk Mountains of British Columbia shift from a diet of primarily vascular taxa during snow-free months to an arboreal lichen – conifer diet during late winter. We present evidence that caribou diets, during the early-winter transition...
