Leslie J. Digby
Associate Professor of the Practice of Evolutionary Anthropology
My research focuses on the behavior and ecology of non-human primates, including how primates balance cooperation and competition in their breeding strategies. In addition, I examine how animals mitigate the costs of temperature extremes through behavior and the use of microhabitats. Our results help us better understand the vulnerabilities of species facing more extreme weather fluctuations.
General Research Interests include:
Evolution of Primate & Human Social Behavior
Primate Behavioral Ecology
Mammalian Reproductive Strategies, Mating Systems, and Infanticide
Primate Microhabitat Use
Primate Behavioral Thermoregulation
Marmosets and Tamarins
