Approximately 80% of the world’s population of northern fur seals (Callorhinus ursinus) once bred and gave birth on the Pribilof Islands of St Paul and St George in the Bering Sea. However, the Pribilof population has declined significantly since then and now numbers less than 20% of its former peak abundance. Scientists are working to understand why the population is declining.
Steller sea lion research
Since 1980, more than 80% of the Steller sea lion population has disappeared, leaving the current wild populations with fewer than 50,000 individuals. In 1997, the U.S. government classified Steller sea lions as “endangered” in the Gulf of Alaska and Aleutian Islands. Read More
Killer whale research
Top predators (animals at the top of the food chain) play an important role in structuring terrestrial and marine ecosystems. Killer whales (Orcinus orca) are a top predator in the North Pacific ecosystem. However, their ecological role, particularly with respect to their impact on marine mammal populations, is not fully understood. Read More
