Isotopic evidence for omnivory among European cave bears: Late Pleistocene Ursus spelaeus from the Peştera cu Oase, Romania.

摘要: Previous bone collagen carbon and nitrogen isotopic studies of Late Pleistocene European cave bears (Ursus spelaeus) have shown that these frequently had low isotope values, similar to those herbivores indicating either unusual physiology related hibernation or a herbivorous diet. Isotopic analysis animal from the Pestera cu Oase (Cave with Bones), Romania, shows most its higher values than associated were, therefore, omnivorous. The are securely identified as by both their morphology DNA sequences. Although many bear populations may behaved like herbivores, data demonstrate were capable altering diets become omnivores even carnivores. These therefore broaden dietary profile U. spelaeus raise questions about nature carnivore guild in Europe.
