Abstract

The progressive growth of urban environments has increasingly forced populations of nonhuman primates to coexist with humans in many cities, which has resulted in problems such as behavioral alterations, conflicts with humans, and threats to the health of the monkeys, due to their consumption of anthropogenic foodstuffs. These anthropogenic foods, which are rich in calories, are the principal driver of the proximity between humans and primates, even though the acquisition of these foods tends to be risky for the monkeys and involve a variety of challenges derived from specific features of the urban environment. The present study evaluated the success/risk relationship of foraging for anthropogenic food by tufted capuchins (Sapajus libidinosus) in Brasília National Park. The data were analyzed using a binary logistic regression, with the backward-stepwise Wald method, to investigate the factors related to the foraging success of the capuchins, considering variables such as their sex and age, the type of approach and its context, and interactions with humans. The capuchins were influenced by the anthropogenic context, which affected their foraging strategies and diet. Interactions with humans reduced the success of foraging for anthropogenic foods. Conflicts between humans and the capuchins were common, especially in the context of access to food. The capuchins thus preferred to access feeding resources directly, probably due to the reduced human interference, which resulted in greater foraging success for unattended food brought by park visitors and the raiding of trash cans. Based on the observed behavior patterns, a number of measures can be proposed to mitigate these conflicts. These recommendations include not bringing food into areas frequented by the capuchins, not reacting to approaching animals, and removing all trash generated during a visit. A cleaning team dedicated to the maintenance of the visitation area free of anthropogenic waste is also be recommended.

与人类的互动降低了巴西巴西利亚国家公园卷尾猴(Sapajus libidinosus)觅食的成功率
随着城市环境的逐步发展,在许多城市中,非人灵长类动物越来越多地被迫与人类共存,这导致了一些问题,如行为改变、与人类的冲突,以及由于猴子食用人类食物而对其健康造成的威胁。这些人为食物含有丰富的热量,是人类与灵长类动物接近的主要驱动力,尽管对猴子来说,获取这些食物往往是危险的,并涉及城市环境特殊性所带来的各种挑战。本研究评估了巴西利亚国家公园丛毛卷尾猴(Sapajus libidinosus)觅食的成功/风险关系。数据分析采用二元逻辑回归法,并考虑了卷尾猴的性别和年龄、觅食方式和环境以及与人类的互动等变量,研究了与卷尾猴觅食成功与否有关的因素。卷尾猴受到人为环境的影响,这影响了它们的觅食策略和饮食。与人类的互动降低了卷尾猴觅食人类食物的成功率。人类与卷尾猴之间的冲突很常见,尤其是在获取食物方面。因此,卷尾猴更愿意直接获取食物资源,这可能是由于人类的干扰减少了,导致卷尾猴对公园游客带来的无人看管的食物的觅食成功率更高,以及对垃圾桶的掠夺。根据观察到的行为模式,可以提出一些措施来缓解这些冲突。这些建议包括不要将食物带入卷尾猴经常出没的区域,不要对靠近的动物做出反应,以及清除游览期间产生的所有垃圾。此外,还建议成立一个清洁小组,专门负责维护探访区内的人为垃圾。

期刊介绍: The objective of the American Journal of Primatology is to provide a forum for the exchange of ideas and findings among primatologists and to convey our increasing understanding of this order of animals to specialists and interested readers alike. Primatology is an unusual science in that its practitioners work in a wide variety of departments and institutions, live in countries throughout the world, and carry out a vast range of research procedures. Whether we are anthropologists, psychologists, biologists, or medical researchers, whether we live in Japan, Kenya, Brazil, or the United States, whether we conduct naturalistic observations in the field or experiments in the lab, we are united in our goal of better understanding primates. Our studies of nonhuman primates are of interest to scientists in many other disciplines ranging from entomology to sociology.
