Giuseppe Donati is a Reader in Primatology. Over the last twenty years Giuseppe has conducted research on behaviour, ecology, and conservation of lemurs and New World monkeys, and produced numerous publications in peer-reviewed journals or books. He initially focussed his research on the unique evolutionary traits of the lemur radiation, and especially their capacity to be active both during the day and at night. Through this work he made a contribution to the understanding of the cost-benefit involved in the transition from the nocturnal to the diurnal life-style during the evolution of primates. Giuseppe’s more recent research addresses a priority area in conservation research, i.e. investigating how primates tolerate habitat change. This work culminated in his involvement in the designing of the Lemur Conservation Action Plan and a leading role on lemur research and conservation in the region of Fort Dauphin (South-eastern Madagascar).
