Research Objectives: This is a long-term research project researching into the biology and behaviour of baboons at Gashaka Gumti National Park, Nigeria. We use data from this site to explore the proximate and ultimate causes of reproductive and life history strategies in primates and in exploring these using a comparative approach. We are also interested at the causes and consequences of crop-raiding by baboons and other wild animals. By focusing on the ecological, behavioural and demographic correlates of crop-raiding in baboons and combining this with work that looks at human attitudes to wildlife we hope to gain insight into the complexities of human-wildlife conflict in this national park.

Field Positions and Volunteers: We sometimes have volunteer positions -please contact for information.

Species Studied: Papio anubis (olive baboon)

Other Species at Site: Cercopithecus mona (mona monkey), Chlorocebus pygerythrus (vervet), Colobus guereza (guereza), Erythrocebus (patas monkey), Lophocebus albigena (gray-cheeked mangabey), Pan troglodytes vellerosus (Nigeria chimpanzee)
