英文摘要: Isotopic tracking of carnivore palaeoecology is a relatively new approach that yielded important results for the study of the non-analogue mammoth steppe biome. After describing the prerequisite to apply this approach and the possible complications, the main achievements will be described for extinct carnivore species such as scimitar-tooth cat Homotherium serum, cave lion Panthera spelaea, giant short-faced bear Arctodus simus, cave bear Ursus spelaeus s.l., as well as for ancient representatives of extant species such as brown bear Ursus arctos and wolf Canis lupus. Isotopic tracking showed that scimitar-tooth cats in Alaska were not specialist proboscidean predators but rather generalist consumers of other large herbivores. The majority of cave lions analysed so far were focused on reindeer, some individuals were specialized on cave bears, especially in contexts of competition with cave hyenas. Giant short-faced bears in Alaska were not pure herbivores and consumed meat from reindeer, muskoxen and possibly other predators, but may have still incorporated plant resources in their menu. In contrast, all cave bear populations studied so far for which a clear dietary reconstruction could be done were virtually pure herbivores, only a few cases are still unclear. Interestingly, brown bears used the opposite extreme of the dietary spectrum when competing with other large bears such as cave bears and giant short-faced bears, i.e. were more carnivorous in Europe and more herbivorous in Alaska. Finally wolves seem to have been outcompeted by hyenas but became dominant predators during the Lateglacial in Europe to the expense of the last cave lions. The results obtained through this approach are also relevant for improving conservation strategies of endangered extant large carnivores. © 2015 The Authors. Citation statistics:
