PhD student in primatology
Marine Larrivaz is a second year doctoral student in primatology in the Department of Anthropology at Udem. Her research topics in primatology focus on primate hierarchy and sexuality. Her thesis concerns a group of colobus magistrate in Ghana. She is working on the problem of simultaneous investment in this species and its factors of appearance. Simultaneous investment is the fact that females can be pregnant and lactating at the same time. Marine is therefore interested in females that are able to avoid lactational amenorrhea. She uses two types of data in her thesis: behavioral data collected in the field that takes into account all the social interactions of a female individual and chemical data that uses stable carbon and nitrogen isotopes to complement the behavioral data and better assess the weaning of the pups. Marine Larrivaz obtained a bachelor's degree in biology from the Université Catholique de Lille, France and a master's degree in fundamental and comparative ethology from the Université Paris Sorbonne Nord, France. Marine Larrivaz is therefore a biologist, ethologist and primatologist.
