Historical antecedents and recent innovations in pitheciid (titi, saki, and uakari) feeding ecology.

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