Table_2_Historical Landscape Use of Migratory Caribou: New Insights From Old Antlers.xlsx

Accumulations of shed caribou antlers (Rangifer tarandus) are valuable resources for expanding the temporal scope with which we evaluate seasonal landscape use of herds. Female caribou shed their antlers within days of giving birth, thus marking calving ground locations. Antler geochemistry ( 87 Sr/...
