Climatic and biotic extreme events moderate long-term responses of above- and belowground sub-Arctic heathland communities to climate change
Climate change impacts are not uniform across the Arctic region because interacting factors causes large variations in local ecosystem change. Extreme climatic events and population cycles of herbivores occur simultaneously against a background of gradual climate warming trends and can redirect ecos...
