My research activities are anchored in community ecology, behavioural ecology, spatial ecology and conservation ecology. I study interspecific interactions, their role in the functioning of communities, and consequences of human activities and global changes on these interactions.

I study interspecific interactions in communities of African large mammals.

I am particularly interested by :

  • Predator-prey interactions
  • Intraguild carnivore interactions
  • Interactions between elephants and other large herbivores
  • The role of scavenging and the interaction between scavenging and active hunting

 

Most of my research is carried out in Hwange National Park, Zimbabwe, a CNRS Long-Term Socio-Ecological Research (LTSER) site, and I recently started to work in Hluhluwe-iMfolozi Park and Madikwe Game Reserve in South Africa. My research is mostly empirical (behavioural observations, use of GPS collars, camera trapping, field experiments). I strongly collaborate with the Wildlife Conservation Research Unit (WildCRU) at Oxford University, and more recently with the Wildlife Ecology Lab at Nelson Mandela University.

In particular, I study the mechanisms underlying habitat selection, movements and foraging strategies of large herbivores and carnivores. In this context, I am particularly interested in the link between individual behaviour and the functioning of populations, communities and food webs. Ultimately, I am trying to take into account the multi-species context of savanna ecosystems by considering the effects of predator-predator interactions and the composition of prey community in foraging strategies, space use and movements of animals.

Finally, I try to understand how human activities inside protected areas (e.g. water management), outside protected areas (e.g. trophy hunting), and climate changes shape the network of interspecific interactions. In a research project funded by the ANR, I am studying the role of climatic and environmental conditions on the hunting success of African large carnivores.

 

PhD and Master students I had/have the chance and pleasure to (co)supervise (in chonological order) - Thanks to all!
