Theme of researches

My main topic of interest is the dynamics of biodiversity in dynamic and heterogeneous agricultural mosaics at different scales. I focus more specifically on the impact of the spatio-temporal organization of cultivated and uncultivated landscape elements on (1) species assemblages and their evolution and on (2) (meta)population dynamics at the mosaics level ; I am also interested in interactions between communities in agro-ecosystems, e.g. weed seed predation by granivorous guilds of ground beetles.
