How do grizzly bears respond to changes in their environment?
Grizzly bears are able to use their strength and size to actively move a wolf pack from its kill. Climate change also is forcing animals to interact with each other in new ways. For example, as the sea ice melts, polar bears spend more time on land, which brings them into greater contact with brown bears.
