Abstrakt:	Protected areas (i.e., reserves and parks) have become an important management tool in conservation of species and communities. Female fur seals spent most of their time east and northeast of the islands on the Kerguelen Plateau at the edge of the 500 m isobaths or along the shelf break at the 1,000 m isobaths (TSPA, Figure a). Antarctic fur seals are pelagic nocturnal central place foragers with time-activity budgets and dive behaviors reflecting their foraging strategies. Accelerometers identify new behaviors and show little difference in the activity budgets of lactating northern fur seals (Callorhinus ursinus) between breeding islands and foraging habitats in the eastern Bering Sea.
