Range use and movement rates of woodland caribou in Saskatchewan
We employed satellite-telemetry data to examine seasonal movement rates, annual- and seasonal-range sizes, and season-to-season range fidelity of female woodland caribou (Rangifer tarandus caribou) from five populations in the boreal forest of Saskatchewan. The populations studied are limited by pre...
