Study: Arctic caribou move up migration due to climate change

St Albert Today discusses how the Arctic caribou have moved up migration due to climate change.

Arctic caribou have moved the start of their spring migration up by almost two weeks to adapt to global heating, a new study suggests – but that hasn’t stopped their populations from plummeting.

University of Alberta ecologist Mark Boyce co-authored a study with researcher Conor Mallory in Oecologia in January on how caribou in Nunavut responded to advancing spring green-up caused by climate change.

Caribou are a vital resource for people in the north yet are in decline worldwide, Boyce said.

“We don’t know for sure why the northern caribou are declining,” he said, but one of the chief suspects is global heating, as it’s one of the few factors present Arctic-wide.
