A trio of researchers from the University of Alberta, Memorial University of Newfoundland and the University of Saskatchewan has conducted a study of population trends for Caribou in the Northwest Territories (NWT) in Canada and has found evidence suggesting population declines are not due to indigenous hunting. In their paper published on the open access site Science Advances, Brenda Parlee, John Sandlos and David Natcher outline their research results and suggest population declines are actually due to mineral exploration.
