Space use patterns affect stable isotopes of polar bears (Ursus maritimus) in the Beaufort Sea

Space use patterns vary within a population and can influence diet composition of individuals. Within the Beaufort Sea, polar bears (Ursus maritimus) either use offshore areas and follow sea ice retreat (pelagic) or utilize nearshore areas (coastal), exposing individuals to different food sources. We examine the relationship between coastal and pelagic space use patterns and diet quantified by stable isotopes (δ15N and δ13C) of polar bears in...
