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.
本研究表明,豹猫(Leopardus pardalis)在巴西东南部的卡拉廷加生物站(CBS)广泛将灵长类动物作为食物资源。对4年期间收集的60份粪便样本进行分析后发现,棕色吼猴(Alouatta guariba)、绒毛蛛猴(Brachyteles hypoxanthus)和棕色卷尾猴(Cebus apella)均遭到捕食。在分析的粪便样本中,最常见的食物是棉鼠(Calomys,n = 16)和未鉴定的鸟类(n = 15),其次是棕色吼猴(n = 12)。虽然啮齿动物是被食用最多的类群(n = 52),但灵长类动物出现在27%的粪便样本中,是就总食物种类而言第三大被食用的类群。特别是,豹猫捕食棕色吼猴(占粪便样本总数的20%)并非个别事件;我们的结果表明,该物种在几个月的时间里都遭到捕食。在CBS,对灵长类动物的捕食远远高于其他开展了类似研究的地点。
