Andreas Koenig is Assistant Professor at the State University of New York at Stony Brook. His research focuses on the evolution of sociality and social behavior, feeding ecology, reproduction, and mating strategies of nonhuman primates. He has worked on South American callitrichines (reproduction, social organization, communal breeding, vigilance) and on Hanuman langurs in Ramnagar (reproduction, ecology of female social relationships). He is currently working on feeding ecology, costs and benefits of group size, and female reproductive success.
Carola Borries is Adjunct Assistant Professor at the State University of New York at Stony Brook. Her research interests are concentrated on male and female reproductive tactics and success, as well as ecological influences on social relationships and reproduction, competition, and social organization among Old World monkeys. Borries has worked on provisioned Hanuman langurs in Jodhpur and unprovisioned ones in Ramnagar. Her current work deals with the factors influencing female reproduction and reproductive success and the behavior of extragroup males. Koenig and Borries are developing a new study site on sympatric langurs and macaques in Thailand. Their research will investigate the evolution of group life, the evolutionary ecology of social organization, and reproductive strategies.
