Data from: Spatial distribution, movements, and geographic range of Steller sea lions (Eumetopias jubatus) in Alaska

Lauri A. Jemison, Grey W. Pendleton, Kelly K. Hastings, John M. Maniscalco & Lowell W. Fritz
The two stocks of Steller sea lions (Eumetopias jubatus) in Alaska include an endangered western stock, recently recovering in parts of its range following decades of decline, and an eastern stock which was removed from the U.S. Endangered Species List in 2013 following increasing numbers since the 1970s. Information on overlapping distributions of eastern and western sea lions is needed for management considerations. We analyzed >30,000 sightings collected from 2000-2014 of 2,385 sea lions that...

Data from: Non-linear effect of sea ice: Spectacled Eider survival declines at both extremes of the ice spectrum

Katherine S. Christie, Tuula E. Hollmen, Paul Flint & David Douglas
Understanding the relationship between environmental factors and vital rates is an important step in predicting a species’ response to environmental change. Species associated with sea ice are of particular concern because sea ice is projected to decrease rapidly in polar environments with continued levels of greenhouse gas emissions. The relationship between sea ice and the vital rates of the Spectacled Eider, a threatened species that breeds in Alaska and Russia and winters in the Bering...
