Polar bears are likely to lose out to grizzly bears in fierce competition for food as climate change drives the two species closer together into shared habitat, biologists concluded in a study released on Tuesday.

The research was based on 3-D computer modeling that compared the skull and jaw strength of the two bruins and found polar bears ill-suited to the tougher chewing demands posed by the largely vegetarian diet of their grizzly cousins.

The study, funded by the National Science Foundation, was conducted by evolutionary biologists at the University of California, Los Angeles, and published in an online journal of the Public Library of Science.

The findings add to mounting signs of threats to polar bears from global warming that scientists attribute to excessive levels of carbon dioxide and other heat-trapping "greenhouse gases" emitted by human activities, such as the burning of fossil fuels.
