• Spring diet of ringed seals (Phoca hispida) from northwestern Spitsbergen, Norway (2007, background): “It is a predator in a strictly marine food chain, and with its broad distribution and year-round availability the ringed seal is itself an important resource for several arctic predators, including polar bears (Ursus maritimus), Arctic foxes (Alopex lagopus), and man (Smith, 1976, 1980; Lydersen and”
• Feeding ecology of phocid seals and some walrus in the Alaskan and Canadian Arctic as determined by stomach contents and stable isotope analysis (2006, background): “These seals are important prey to higher trophic level organisms, including Arctic fox (Alopex lagopus), polar bear (Ursus maritimus), humans and some walrus (Odobenus rosmarus) (Smith 1976; Lowry and Fay 1984; Hammill and Smith 1991; Derocher et al. 2002 ).”
• Quantifying the sensitivity of Arctic marine mammals to climate-induced habitat change. (2008, background): “Bearded seals are preyed upon by polar bears (Stirling and Archibald 1977, Smith 1980, Derocher et al. 2002) and walruses (Lowry and Fay 1984).”
• Importance of fast ice and glacier fronts for female polar bears and their cubs during spring in Svalbard, Norway (2012, unknown): “In addition, bearded seals Erignathus barbatus and harp seals Pagophilus groenlandicus occur in the pack-ice areas around Svalbard during spring (Haug et al. 1994, Isaksen & Wiig 1995), and these species have been recorded in the diet of polar bears from this area (Lønø 1970, Derocher et al. 2002).”
• The prevalence of Toxoplasma gondii in polar bears and their marine mammal prey: evidence for a marine transmission pathway? (2010, background): “Ringed and bearded seals, which are two of the main prey species for polar bears in Svalbard (Derocher et al. 2002), showed high prevalence rates of T. gondii in this study.”
• Population ecology of polar bears at Svalbard, Norway (2005, background): “Given that ringed seals are a primary prey species of polar bears in the Barents Sea (Derocher et al. 2002) and the linkages between body condition and reproductive rates in polar bears (Derocher and Stirling 1994, 1998), the linkage between polar bear reproduction and the Arctic Oscillation may be…”
• POLAR BEAR DIETS AND ARCTIC MARINE FOOD WEBS: INSIGHTS FROM FATTY ACID ANALYSIS (2008, background): “However, more recent studies by Derocher et al. (2002) and Iverson et al. (2006) have indicated that harp seals (Pagophilus groenlandica) may also be important prey in areas where they are available.”
