Doctoral Candidate STEPHANIE RAMIREZ

Research Interests: My research has been focused in the field of primatology investigating ultimate and proximate causes of maternal behavior and infant development in female baboons (Papio hamadryas anubis), specifically investigating the relationship between maternal behavior and ovarian and stress hormones. My current research interests include the impact of seasonal variation on the reproductive behavior and physiology of female spider monkeys (Ateles geoffroyi), specifically examining resource availability, energy intake and expenditure, and ovarian function.

Advisor: Dr. Thad Bartlett

Degrees: M.A. Anthropology, University of Texas at San Antonio (2004)

Dissertation Topic: The Impact of Seasonal Variation in Food Resources and Ranging Patterns on the Reproductive Physiology and Behavior of Female Spider Monkeys (Ateles geoffroyi)
