对生活在刚果北方努瓦巴莱-恩多基国家公园的西部低地大猩猩（Gorilla gorilla）的摄食生态进行了为期一年的调查。这是第一个明确大猩猩在一整年中觅食习惯的季节性变化的记录，生活在几乎完全不受干扰的原始低地森林中。粪便内容物，喂养痕迹，直接观察进行了分析，参考水果的可用性调查。虽然大猩猩主要以森林中的水果为食，但它们的基本饮食是植物的纤维部分，包括嫩枝，嫩叶和树皮。陆生草本植物，如竹芋科的单子叶植物和富含蛋白质和矿物质的水生草本植物，即使在结果季节也经常被食用。由于这些高营养纤维食物全年都过剩，恩多基大猩猩的主要食物似乎就是这些植物。然而，他们选择水果作为他们的替代食物资源在结果季节。大猩猩以许多水果为食，同时对某些特定物种表现出强烈的偏好。沼泽森林，包括沼泽草原，是恩多基大猩猩的重要和经常栖息地。
The feeding ecology of western lowland gorillas (Gorilla gorilla gorilla) living in the Nouabalé-Ndoki National Park, northern Congo, was surveyed for one full year. This is the first record to make clear the seasonal changes in the feeding habits of gorillas in a whole year, living in the primary lowland forest almost completely undisturbed. Fecal contents, feeding traces, and direct observation were analyzed with reference to a fruit availability survey. Although the gorillas fed largely on fruits in the forest, their basic diet was fibrous parts of plants, including shoots, young leaves, and bark. Terrestrial herbaceous vegetation, such as monocotyledons of the Marantaceae and aquatic herbs having much protein content and minerals, were frequently eaten even in the fruiting season. As these highly nutritious fibrous foods were superabundant all year, the major foods of the Ndoki gorillas seemed to be those plants. However, they selected fruits as their alternative food resources in the fruiting season. Gorillas foraged on many fruit species, while showing strong preferences for some particular species. The swamp forest, including marshy grasslands, was an important and regular habitat for the Ndoki gorillas.
