卷尾猴（Cebus olivaceus）在觅食和饮食方面表现出广泛的组内差异。为了考虑年龄、性别和个体身份如何影响这种变异性，作者研究了野外1个社会群体中18只楔帽卷尾猴的觅食和饮食。两性班没有不同的时间花在食物，依赖植物性食物，觅食行动或底物利用，或在利用动物性食物的效率。然而，它们在寻找食物所花的时间、用于动物性食物的时间、用于积极觅食的时间以及觅食的效率方面确实存在差异。性别差异大于年龄组。年龄-性别类别内的个体差异比预期的要小，并且在青少年中比成年人更明显。组内变异觅食反映天主教的选择和同等待遇的基板所有个人，而不是个人的专业化。（PsycINFO数据库记录（c）2017阿帕，保留所有权利）
Capuchin monkeys (Cebus olivaceus) exhibit extensive intragroup variability in foraging and diet. To consider how age, sex, and individual identity contribute to this variability, the authors examined foraging and diet in 18 wedge-capped capuchin monkeys in 1 social group in the wild. Age–sex classes did not differ in the time spent ingesting food, the reliance on plant foods, the foraging actions used or substrates exploited, or in the efficiency of exploiting animal foods. They did differ, however, in the time spent finding food, time devoted to animal foods and to vigorous foraging, and the efficiency of foraging. The sexes differed more than age groups. Individual differences within age–sex class were less extensive than expected and were more evident in juveniles than adults. Within-group variability in foraging reflected catholic selection and equivalent treatment of substrates by all individuals, rather than individual specializations.(PsycINFO Database Record (c) 2017 APA, all rights reserved)
