Selection of cricetine prey by the culpeo fox in patagonia : A differential prey vulnerability hypothesis

The Patagonian culpeo fox (Dusicyon culpaeus) feeds in part on the cricetine rodent community. A previous diet study based on scats revealed that these foxes show a marked preference for 3 Akodon species (Akodon longipilis, Akodon xanthorrinus and Akodon iniscatus), in contrast with the notably more...

To do so, we compared behavioural and morphological attributes that could account for differences in the predators success (studied separately through stomach content analysis). Our results show that there are differences in the vulnerability of these prey species which are based mainly upon a greater escape ability of E. typus related to their longer hind legs. We conclude that analyses such as these, which are simple and economical, can provide interesting data on which future experimental work on carnivore prey choice may be based upon. © 1995, Walter de Gruyter.
