这份报告描述了加蓬中部洛佩低地大猩猩大猩猩的饮食组成。该种群生活在成熟的常绿热带森林中，不习惯于人类观察者。数据是在一项正在进行的长期研究的6年中收集的，来自喂养踪迹和直接观察，但主要是通过粪便分析。大猩猩吃来自36科134个物种的182种植物食物。水果的饮食是多样化的：食用了95种水果，大多数果肉多汁，还吃了一些未成熟的种子。98%的粪便中有水果残留物。鸡冠花和马蹄莲的营养部分是主食，因为它们丰富，可获得，全年可用。土壤和社会性昆虫也被摄入；三分之一的粪便中记录了编织蚂蚁的遗骸。洛佩为大猩猩记录的食物比其他地方都多，这是迄今为止研究过的最爱吃水果的种群。
This report describes the composition of the diet of lowland gorillas, Gorilla gorilla gorilla, at Lopé in central Gabon. This population inhabits mature evergreen tropical forest and is not habituated to human observers. Data were collected during 6 years of an ongoing long‐term study, from feeding‐trails and by direct observation, but mostly by fecal analysis. Gorillas ate 182 plant foods from 134 species and 36 families. The fruit diet was diverse: 95 species were consumed, most with succulent pulp, and some immature seeds were eaten. Fruit remains were recorded in 98% of dung. Vegetative parts of Aframomum and Marantaceae formed staple foods, as they were abundant, accessible, and available year‐round. Soil and social insects were also ingested; remains of weaver ants were recorded in one third of feces. More foods have been recorded for gorillas at Lopé than elsewhere and this is the most frugivorous population studied so far.
