Cercopithecus monkeys are a species-rich genus generally considered arboreal frugivores with widespread distribution in sub-Saharan African forests. We studied a largely undocumented species threatened by habitat fragmentation, Cercopithecus denti, during 3 months in 2017 in a small forest fragment of Nyungwe National Park, Rwanda. C. denti's diet was composed of about 58% leaves and 18% fruits. They spent most of their time 10–20 m above ground in secondary forest and open areas. This first systematic study of C. denti shows capacity for a highly folivorous diet, supporting arguments that Cercopithecus have flexible diets, likely enabling persistence in forest fragments.

对生活在卢旺达森林碎片中的丹特猴（Cercopithecus denti）的初步研究，强调了长尾猴的饮食灵活性

Cercopithecus 猴是一个物种丰富的属，通常被认为是树栖食果动物，广泛分布在撒哈拉以南非洲森林中。 2017 年的 3 个月时间里，我们在卢旺达 Nyungwe 国家公园的一小片森林中研究了一种很大程度上受到栖息地破碎化威胁的未记录物种，Cercopithecus denti。 C. denti 的饮食由大约 58% 的叶子和 18% 的水果组成。它们大部分时间都在次生林和空旷地区度过，距离地面 10-20 米。这是对C 的首次系统研究。 denti 显示出高度食叶性饮食的能力，支持了Cercopithecus 具有灵活饮食的论点，可能有助于在森林碎片中持久存在.
