Ocelot (Leopardus pardalis) predation on primates in Caratinga Biological Station, Southeast Brazil.

This study demonstrates that ocelots (Leopardus pardalis) extensively use primates as a food resource at the Caratinga Biological Station (CBS) in Southeast Brazil. Analysis of 60 fecal samples collected over 4 years revealed predation upon the brown howler monkey (Alouatta guariba), the muriqui (Brachyteles hypoxanthus), and the brown capuchin monkey (Cebus apella). The most frequent items found in the fecal samples analyzed were Calomys (n=16) and non-identified Aves (n=15), followed by A. guariba (n=12). Although Rodentia was the most common group consumed (n=52) Primates were found in 27% of total fecal samples and were the third most consumed group in relation to the total items. Particularly, predation of A. guariba by ocelots (20% of the total fecal samples) was not an isolated event; our results showed that this species was preyed on across several months. Predation on primates was far higher at CBS than at other sites where comparable studies have been carried out. Copyright 2007 Wiley-Liss, Inc.
