Long-term Interactions between Migratory Caribou, Wildfires and Nunavik Hunters Inferred from Tree Rings
Barren-ground caribou (Rangifer tarandus) herds in North America may reach considerable size and undertake large-scale seasonal migrations from the Arctic tundra to the boreal forest. To test the caribou decline hypothesis associated with native harvesting and fire, we have docu-mented the long-term...
