Dr Eve Davidian is a postdoctoral researcher with the Institute of Evolutionary Science in Montpellier and co-director of the long-term Ngorongoro Hyena Project in the Ngorongoro Crater, Tanzania. Eve applies concepts and theories from behavioral ecology, evolutionary biology and socio-endocrinology to study the determinants and fitness consequences of individual strategies to acquire resource, mates, social allies, and social status in group-living animals. She is particularly interested in understanding how socio-ecological factors shape individual decisions and how these decisions in turn generate patterns and processes at the level of social groups and populations.
