PRIME is a collaborative research programme focused on wild baboons and vervet monkeys in South Africa, with core ongoing field sites at the Swebeswebe Wildlife Estate and Telperion Nature Reserve. Our programme addresses key questions in behavioural ecology, social evolution, and environmental physiology, using long-term field studies to understand how primates adapt to complex and changing environments. PRIME brings together a network of researchers with expertise in behaviour, ecology, physiology, epidemiology, and data science. This collaborative approach links social dynamics, environmental pressures, and individual health in natural populations. We welcome enquiries from prospective collaborators and students interested in field experience or postgraduate research opportunities at our partner institutions.
