Recent observations of intraspecific predation and cannibalism among polar bears in the southern Beaufort Sea / Steven C. Amstrup, Ian Stirling, Tom S. Smith, Craig Perham, Gregory W. Thiemann.

Title: Recent observations of intraspecific predation and cannibalism among polar bears in the southern Beaufort Sea / Steven C. Amstrup, Ian Stirling, Tom S. Smith, Craig Perham, Gregory W. Thiemann.

Date: 2006.
In: Polar Biology. (2006.), Vol. 29(11) (2006)
Abstract: Reports observation of three instances of intraspecific predation and cannibalism among polar bears (Ursus maritimus) in Beaufort Sea between 24 January-10 April 2004. Instances include killing of parturient female bear at maternal den. Hypothesizes that nutritional stress related to longer ice-free seasons is leading to recently observed incidents of cannibalism.
