Predicting survival, reproduction and abundance of polar bears under climate change. (2010, unknown): “1) (Cherry et al., 2009), and recent incidents of cannibalism and an increased presence of polar bears near human settlements may provide further indicators for food stress in various populations (Amstrup et al., 2006; Stirling and Parkinson, 2006; Towns et al., 2009).”
POLAR BEAR DIETS AND ARCTIC MARINE FOOD WEBS: INSIGHTS FROM FATTY ACID ANALYSIS (2008, background): “…1987, Smith and Sjare 1990), narwhals (Monodon monoceros; Smith and Sjare 1990), walruses (Odobenus rosmarus; Calvert and Stirling 1990), and even conspe- cifics (Taylor et al. 1985, Amstrup et al. 2006, Stone and Manuscript received 27 June 2007; revised 25 February 2008; accepted 13 March 2008.”
Climate change and cetaceans: concerns and recent developments (2009, background): “The threat posed by climate change to them is well recognized and a recent study suggests that one result of reduction in prey seems to be novel cannibalistic behaviour (Amstrup et al., 2006).”
Consequences of long-distance swimming and travel over deep-water pack ice for a female polar bear during a year of extreme sea ice retreat (2011, background): “Nonetheless, some observations which are not based on systematic surveys alert researchers and managers of phenomena that are potentially significant to the population (e.g., cannibalism; Amstrup et al. 2006).”
Variation in winter diet of southern Beaufort Sea polar bears inferred from stable isotope analysis (2007, unknown): “Other potential dietary sources for southern Beaufort Sea polar bears, such as cannibalism on other bears (Derocher and Wiig 1999; Dyck and Daley 2002; Amstrup et al. 2006) and feeding on terrestrial mammals such as caribou (Rangifer tarandus (L.”
