Fields of Study
Primate social behavior, ecology and conservation biology, with a special focus on African rain forests; plant chemistry and food selection by mammals; zoogeography and evolutionof African primates; West Africa, India.
Current Research Interests
I am currently giving special attention to the factors that influence the distribution and abundance of African rain-forest monkeys. This has involved an extension of some of my earlier studies that analyzed relationships between plant chemistry and food selection by colobines to a broader examination of the determinants of biomass in whole primate communities (e.g., at Tiwai Island in Sierra Leone). My zoogeographical studies have led to the establishment of new range limits for several primates, and they will be deepened to gain insights on speciation processes within the African forest zone; in this work, geographical analysis is being combined with studies of vocalizations and, in collaboration with NYCEP colleagues, of evolutionary genetics. My studies are also showing the profound impact that humans are having on the distribution and abundance of forest-living monkeys and apes in Africa. This has led me to a deepening involvement with conservation issues.
