• Rapid ecosystem change and polar bear conservation (2013, background): “…from changing sea ice include declines in body condition, body size, reproductive and survival rates, popula- tion size, sea ice denning habitat, as well as altered movements and distribution (Stirling et al. 1999; Fischbach et al. 2007; Regehr et al. 2007; Rode et al. 2010; Derocher et al. 2011).”

• Footprints of climate change in the Arctic marine ecosystem (2011, background): “…to the criteria established by International Panel of Climate Change (IPCC) working group II for assessing impacts of climate change on biota (Fischlin et al., 2007): studies (1) ending in 1990 or later; (2) spanning a period of at least 20 years; and (3) showing a significant change in…”
• Impacts of changing sea-ice conditions on Arctic marine mammals (2011, background): “Polar bear denning locations have shifted in some regions in response to changing ice conditions, with fewer dens in MYI and more on shore (e.g., Fischbach et al. 2007).”
• Effects of sea ice extent and food availability on spatial and temporal distribution of polar bears during the fall open-water period in the Southern Beaufort Sea (2008, background): “…and BaYn Bay, includes spending up to 4 months of the year on land during the fall open-water period (Stirling et al. 1977; Derocher et al. 1993; Ferguson et al. 1997, 2000), polar bears in Alaskan populations, including the Southern Beaufort Sea (SBS) and Chukchi Sea, and other open basin…”
