Research Objectives: My research has focused on studying plant-primate interactions. Currently I am directing a long-term field project (begun in 1970) investigating the interaction between plant-produced chemicals and primate feeding behavior as well as the impact this has on primate social organizations. My research objectives have expanded to include: evaluating the plant-primate interaction from an ethnobotanical perspective; the evolutionary development of optimal group size and composition; the relationship between food quality and quantity and body size; the factors affecting short and long-term demographic changes in established groups; and the role of regenerating forests on primate density. I am completing my 36th year of data collection on a population of about 60 individually marked mantled howling monkeys (Alouatta palliata) living in dry forests in northwestern Costa Rica.
