Modern and ancient DNA reveal recent partial replacement of caribou in the southwest Yukon
Abstract The long‐term persistence of forest‐dwelling caribou ( Rangifer tarandus caribou ) will probably be determined by management and conservation decisions. Understanding the evolutionary relationships between modern caribou herds, and how these relationships have changed through time will prov...
