最近对扎伊尔中部树栖长尾猴和白眉白眉猴的摄食生态学的研究表明，这些通常食果的物种 [1, 2] 主要以树叶、假种皮和种子为食，只吃 5-12% 的肉质水果 [3;取消发布。数据]。影响植物中可用营养物质水平的两个主要因素：首先是其消化率，这在很大程度上取决于细胞壁含量，其次是消费者的肠道通过率（GPR）[4]，叶子的细胞壁物质比例高于多汁水果，需要在肠道中更长的时间才能有效消化[4, 5]，对灵长类动物[5-8]（包括果食性和杂食性物种）进行的 GPR 研究表明（1）当猴子是
Recent work on the feeding ecology of arboreal guenons and mangabeys in Central Zaire showed that these normally frugivorous species [1, 2] fed largely on leaves, arils and seeds and ate only 5-12% fleshy fruit [3; unpubl. data]. Two main factors affect the level of available nutrients in a plant: firstly its digestibility, which depends largely on cell wall content and secondly the gut passage rate (GPR) of the consumer [4], Leaves, which have a higher proportion of cell wall material than succulent fruit, require a longer time in the gut for efficient digestion [4, 5], Studies of GPR conducted on primates [5-8], including both frugivorous and omnivor ous species, show that (1) when monkeys are
