The modern pitheciids (titis, sakis, and uakaris) of northern South America represent one of the earliest radiations of platyrrhines and demonstrate morphological adaptations and ecological strategies for seed eating. While seeds can provide reliable resources for relatively long periods of time, they are often well protected by thick husks and hard seed coverings. Seeds also tend to be rich in lipids, but they may also be high in indigestible fiber. Even though seed eaters are found in each major primate radiation, only the pitheciids demonstrate primary adaptations for eating seeds. In this partly historical, partly contemporary review, I examine the ecological and anatomical correlates of seed eating. It is dedicated to two well-known field primatologists: ecologist and conservationist J. Márcio Ayres; and anatomist and ecologist Warren G. Kinzey. Using observations in Kinzey (1992, Am J Phys Anthropol, 88, pp. 499–514) as a framework, I provide context and analysis for the intervening three decades of pitheciid research to identify what we know about this understudied group of primates and propose directions for future work.

pitheciid(titi、saki 和 uakari)饲养生态学的历史前因和最近的创新

南美洲北部的现代 pitheciids(titis、sakis 和 uakaris)代表了桔梗最早的辐射之一,并展示了食用种子的形态适应性和生态策略。虽然种子可以在相对较长的时间内提供可靠的资源,但它们通常受到厚厚的外壳和坚硬的种子覆盖物的良好保护。种子也往往富含脂质,但它们也可能富含难消化的纤维。尽管在每个主要的灵长类辐射中都发现了种子食者,但只有 pitheciids 表现出对吃种子的主要适应性。在这篇部分历史、部分当代的评论中,我研究了食用种子的生态和解剖学相关性。它献给两位著名的野外灵长类动物学家:生态学家和保护主义者 J. Márcio Ayres;解剖学家和生态学家 Warren G. 金泽。使用 Kinzey (1992,Am J Phys Anthropol, 88 , pp. 499–514) 作为一个框架,我为介入的三个十年的 pitheciid 研究提供背景和分析,以确定我们对这个未被研究的灵长类动物群的了解,并为未来的工作提出方向。
