Can polar bears use terrestrial foods to offset lost ice‐based hunting opportunities?

Increased land use by polar bears ( Ursus maritimus ) due to climate‐change‐induced reduction of their sea‐ice habitat illustrates the impact of climate change on species distributions and the difficulty of conserving a large, highly specialized carnivore in the face of this global threat. Some authors have suggested that terrestrial food consumption by polar bears will help them withstand sea‐ice loss as they are forced to spend increasing...
