The study of interspecific interactions will develop research in trophic ecology, by analysis of diets and via different biochemical tracers, in order to better understand how organic matter circulates within communities.

It will also aim to understand the role of interspecific competition, prey-predator and host-pathogen relationships, and density-dependent effects on ecosystem structure and functioning.

Research on biological community dynamics aims to better understand the vulnerability and resilience of biological communities by examining their spatial structures and temporal trajectories, and to assess the importance of life history traits and population dynamics in community change in the face of natural and anthropogenic modifications.
