Publisher Description

Abstract The Pacific region off the coast of North America has undergone dramatic changes over the past 50 years. These include: declines in Steller sea lion and sea otter populations in Alaska; decreases in salmon populations in British Columbia and Washington State; increased populations of fish such as pollock in the Bering Sea; changes in food supply for sea birds; and changes in the migration of gray whales. Although the causes of these changes are not fully understood, they are forcing scientists to think about the need to move beyond current approaches that focus on economically important species to marine management.
