But these studies were isolated and doubts remained as to the true trigger of these movements and migrations. But now comes evidence from the largest-scale analysis to date that such northward, migratory expansions and accelerating movements up-slope are largely attributable to warming and climate change. The ecological impacts of these shifts are unknown at present
