This work characterizes differences in selection of Talisia retusa fruits by two sympatric Neotropical primates, Pithecia pithecia (white-faced sakis) and Alouatta seniculus (red howlers). Color appears to be the criterion by which fruits were selected. Greenish fruits were mainly eaten by Pithecia, while yellowish fruits by Alouatta. The characteristics of these primates in relation to seed predation and seed dispersal are discussed in the context of the Talisia retusa fruit color spectrum. Furthermore, a possible differential acquisition of chemical components, like tannins, is hypothetically treated considering the variation in fruit color.
这项研究描述了两种同域分布的新热带灵长类动物——白面僧面猴（Pithecia pithecia）和红吼猴（Alouatta seniculus）对钝叶塔莉西亚果实的选择差异。颜色似乎是选择果实的标准。绿色果实主要被白面僧面猴食用，而黄色果实则被红吼猴食用。在钝叶塔莉西亚果实颜色光谱的背景下，讨论了这些灵长类动物与种子捕食和种子传播相关的特征。此外，考虑到果实颜色的变化，假设性地探讨了它们对单宁等化学成分的不同获取情况。
