I am interested in the behavior of threatened species, and in how flexibility in behavior affects species' capacity for persistence in human-dominated landscapes. I combine observations from the field and existing data on species diets, conservation status, and distribution to address questions such as, "Are specialist primates less flexible and innovative than generalist primates?" and "Do primate and felid populations that exploit tropical swamp forests have better survival probabilities than populations which do not?" In Tanzania, I am involved in several initiatives including mitigation of conflict between people and elephants, and setting of national conservation priorities. I am currently developing a new project on risk, fear and cognition in samango monkeys in South Africa.
