Research interests

Resarch activities

My core personal research focuses on theoretical issues at the individual and population levels of ecological organisation, and on the task of linking population dynamics with behavioural ecology, within the framework of evolutionary ecology. In addition to basic research, I am interested in bringing modern ecological theory to bear on significant applied problems, specifically in conservation biology. Hence, my research activities so far have focused on behaviour mechanisms underlying the Allee effect and its consequences for conservation biology. I have collaborated with many researchers at a wide range of institutions, both inside and outside France.

Main research question

My research activities so far were build around the generic question of «What is the role of inter-individual interactions in the individuals’ ability to cope with a changing environment?»This generic question was approached considering how different types of inter-individual interactions (e.g. «cooperation» through mating systems, and social foraging), were impacted by anthropogenic disturbance leading to reduced population size or to changes in the resources exploited.

Current research projects

RAREResearch on Allee and Rarity Effects (coordinated by Franck Courchamp). My focus are behavioural Allee effects, in particular the impact of group living on small population dynamics. I’m particular interested in the impact of group living on primate population dynamics and extinction risk and currently collaborating with Guy Cowlishaw (IoZ, UK).

SoftpopFrom SOcial Foraging To POpulation Processes: an integrated approach to population dynamics (coordinated by François Sarrazin). This research programme investigates how resource distribution in space and time, and in particular its spatial predictability affect information use by social foragers. Our model system are scavenger raptors and we are particularly interested in exploiting how our results can be used in vulture conservation programmes.
