The Impact of Climate Change on Phenological Mismatch in Migratory Caribou
Quick fact
In some caribou herds, the spring green-up now occurs up to two weeks earlier than it did decades ago, while the caribou's migration timing has barely shifted, creating a growing mismatch.
Why this is interesting
Every spring, caribou undertake one of the longest land migrations on Earth, arriving on the calving grounds just as the Arctic tundra turns green. But as the planet warms, they may be arriving too late—why?
