Polar bears in Ontario are at the southern limit of their species’ range. As part of the Southern Hudson Bay subpopulation, these roughly 800 bears migrate onto land when the sea ice of Hudson Bay melts completely each summer. On shore, polar bears primarily fast and rely on stored fat for energy. With increasing global […]
