David is a behavioural ecologist interested in the behavioural adjustments of individuals in responses to environmental changes, especially changes in temperature and water availability. At a broader scale, his aim is to understand how animal behaviour could buffer the local effects of global change and ultimately to predict individuals’ activity window under different climate change scenarios. David received his PhD in 2019 from Sorbonne Université in Paris, during which he described and studied thermo-hydroregulation behaviours in the common lizard in response to variable temperature, water presence and moisture conditions. In 2020, David was awarded an Alexander von Humboldt Postdoctoral Fellowship to join the Vulturine Guineafowl Project in the Farine Lab. His project focuses on describing how thermal conditions and overheating risk influences activity patterns, movement decision-making processes and foraging probability of individuals during dry seasons, when resources are scarce and segregated. He will also have a particular interest in highlighting how group-living influences the costs-benefits ratio of behaviours in these high constraints environments. One of his main task is to map the heat constraints landscape to predict the local overheating risk and shade availability across the day in groups’ home ranges. Ultimately, his research could give insights on the consequences of global changes on this population of vulturine guineafowl.
