Guest editorial—the ballyhoo over polar bears

Article English OPEN
Vongraven, Dag (2009)

Critics have said that there’s little or no justification for the focus that polar bears (Ursus maritimus) have received as a threatened species. Recent studies project dramatic reductions in polar bear numbers in just a few decades, in concert with the equally dramatic reduction in critical sea-ice habitat, yet there are undoubtedly ecologically more “important” species in tropical and temperate latitudes that are facing equal or more urgent problems at present.
