My study is the first to examine the nutritional composition of wild capuchin foods and compare ingestion, nutrient and energy intake rates among: 1) groups with different habitats 2) males and females; and 3) females in different reproductive states. Females inhabiting early successional forest displayed higher rates of insect, fat and protein ingestion than females in semi-evergreen habitat. This suggests that monkeys in younger forests may compensate for lower quality habitat by consuming more food. Lactating females had higher ingestion rates than other females and tended toward higher nutrient intake rates, perhaps due to costs of milk production and infant care. However, overall energy intake rates were not significantly different by group, sex or reproductive state, suggesting that energy may be a limiting factor for capuchins and remain constant across individuals, even as their diets vary.

- ItemOpen AccessThe function and mechanisms of alarm calls, lost calls and close contact calls in the white-faced capuchin (Cebus capucinus)(2004) Digweed, Shannon Marie; Fedigan, Linda M.The goal of animal communication research is often to identify the meaning and function of vocal signals. My analysis of white-faced capuchin alarm calls suggests two different types, "aerial" and "terrestrial", however, it does not provide support for any one traditional hypothesis (motivational, referential, affect-induction). Instead it suggests an integration of hypotheses; motivationally based calls allow functionally distinct responses via effects on listener attention. Analysis of lost calls suggests they provide cues to location and individual identity, facilitating antiphonal responses from receivers, which then provide mutual benefits. Finally, my analysis of close contact "huh" calls suggest, due to cues to identity and call frequency in close proximity situations, that calls facilitate within-group spacing. Overall, my research provides an integration of theoretical concepts, through analysis of the mechanisms and function of capuchin alarm calls. Additionally, analysis of lost and "huh" calls provides a better understanding of the white-faced capuchin vocal repertoire.
