The Social and Reproductive Behavior of Male Chimpanzees in Gombe National Park, Tanzania
This dissertation presents three studies of the social and reproductive behavior and social structure of male chimpanzees (Pan troglodytes schweinfurthii) in Gombe National Park, Tanzania. I. In many species of non-human ...
Water Scarcity, Distribution, and Quality as Drivers of Lemur Behavior
Because water is essential for life, when it is scarce, it may be one of the most important drivers of animal behavior. Despite its clear importance, water is relatively poorly studied in terms of its impact on primate behavior, ...
The Evolution of Extended Sexual Receptivity in Chimpanzees: Variation, Male-Female Associations, and Hormonal Correlates
Sexual conflict occurs when female and male fitness interests diverge. In a social system characterized by aggressive sexual coercion and the risk of infanticide, female chimpanzees (Pan troglodytes) respond to this conflict ...

Humans are natural politicians. We obsessively collect social information that is both observable (e.g., about third-party relationships) and unobservable (e.g., about others’ psychological states), and we strategically ...
Predictors, Costs, and Consequences of Larval Tapeworm Infection in Geladas (Theropithecus gelada).
Parasitism is integral to primate evolution, contributing to major life history tradeoffs with other processes critical to reproductive success and survival. I investigate how infection with the tapeworm Taenia serialis ...
Sexual Selection in Mantled Howling Monkeys (Alouatta palliata), With an Emphasis on the Role of Female Mate Choice
Despite early neglect, recent studies of sexual selection have shown a renewed interest in female reproductive strategies. Clearly the traditional portrayal of female animals as passive participants in mating is incorrect, ...
