Natal dispersal is an important life-history stage influencing individual fitness, social dynamics of groups and population structure. Understanding factors influencing dispersal is essential for evaluating explanations for the evolution and maintenance of social organization, including parental care and mating systems. The social and mating system...
Current evidence indicates that owl monkeys (Aotus spp.) have species-rich, flexible diets. They can switch resources seasonally, consume ephemeral foods of many life forms, and locate food in small, degraded forests. They focus on fruits (20–87%) yet regularly consume flowers, leaves, and/or insects. Common dietary components are Fabaceae flowers...
Background/Question/Methods
Peat swamp forests are endangered habitats in Southeast Asia that harbor diverse primate communities. We investigated tree species’ phenological traits to increase understanding of tropical peat-swamp forest phenology. This is important as many primates exhibit behavioral and physiological responses to fuctuations in phe...
Limited food resource availability during yearly dry seasons can influence population dynamics and direct life-history evolution. We examined actual food production during two dry seasons and its relationship to feeding, life history, and demography in territorial, monogamous, and pair-living owl monkeys (Aotus azarae azarae). To quantify food avai...
Small-scale ecological variables, such as forest structure and resource availability, may affect primate groups at the scale of group home ranges, thereby influencing group demography and life-history traits. We evaluated the complete territories of 4 groups of owl monkeys (Aotus azarai), measuring and identifying all trees and lianas with a diamet...
Owl monkeys are territorial, monogamous monkeys from Central and South America living in groups of 4-5 individuals. They are omnivorous, with fruits dominating their diet. Our objective was to evaluate ten years of forest dynamics and the possible implications of changes in the availability of plant food for owl monkeys. The study site is situated...
