Data are presented from an 11-month study of the ranging movements of a group of Colobus satanas in a rain forest on the coast of Cameroon. Discussion centers on correlations between seasonal variation in ranging behaviour and seasonal variation in food availability, diet composition and diversity, and weather conditions. The data support the hypothesis that the scarcity of nutrient-rich, highly digestible leaves in this site has led to a feeding strategy based on seeds, which are characterised by high nutritive quality and occurrence in large clumps, allowing monotonous feeding and low expenditure of energy in ranging movements.
本文呈现了对喀麦隆海岸雨林中一群黑疣猴活动范围移动情况进行的为期11个月的研究数据。讨论集中在活动范围行为的季节性变化与食物可获得性、饮食组成与多样性以及天气状况的季节性变化之间的相关性。数据支持了这样一种假设，即该地点营养丰富、易消化的树叶稀缺，导致了一种基于种子的觅食策略，种子具有高营养品质且成大团出现，这使得觅食单调，且在活动范围移动中能量消耗较低。
