Three themes of ongoing research: forecasting polar bear and walrus population response to changing marine ecosystems; measuring wildlife population changes in the Arctic coastal plain, and wildlife communities in the boreal-Arctic transition zone.
Changes in both the ocean and coastal ecosystems may have negative effects on sea otter populations in the coastal Northwest and Alaska. A study underway will examine these factors and the overall health of sea otter populations.
Population size, foaling, deaths, age structure, sex ratio, age-specific survival rates, and more over a 14 year time span. This information will help land and wildlife managers find the best maintenance and conservation strategies.
