  • We investigated the use of stable-carbon isotope analysis of serum and cellular fractions of blood to detect the extent of terrestrial feeding in polar bears on land during the ice-free period in western Hudson Bay. We compared blood in bears that were restricted entirely to coastal areas, who showed no evidence of terrestrial feeding, with blood in bears sampled at inland locations and who were known to have fed on berries of Vaccinium uliginosum and Empetrum nigrum. Despite a separation of… CONTINUE READING
