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.
本报告描述了加蓬中部洛佩地区低地大猩猩(Gorilla gorilla gorilla)的饮食构成。该大猩猩种群栖息于成熟的常绿热带森林,且未习惯与人类观察者接触。数据收集自一项正在进行的长期研究的6年期间,通过觅食小径观察、直接观察,但主要是通过粪便分析。大猩猩食用了来自36个科134个物种的182种植物性食物。其水果饮食种类多样:共食用了95种水果,大部分水果果肉多汁,还食用了一些未成熟的种子。98%的粪便中都记录到了水果残渣。非洲豆蔻属植物和竹芋科植物的营养部分构成了主要食物,因为它们数量丰富、易于获取且全年都有。土壤和群居昆虫也被摄入;三分之一的粪便中记录到了织叶蚁的残骸。与其他地方相比,洛佩地区的大猩猩记录到的食物种类更多,且这是目前研究中食果性最强的种群。
