______________________________________________________________________________________________________________ Identifying the patterns in the structure and dynamics of aquatic communities and populations, and understanding the involved mechanisms, regroup the ecological topics that have guided my research. The main target of my research is focused on the knowledge of the current and historical environmental factors that explain the spatial and temporal distribution of freshwater communities in tropical and temperate regions as a function of their biological traits and following a multi-scale approach: between-continents, between drainages basins and within drainage basins, and historical, inter-annual and seasonal. From a ‘fundamental’ point of view, my recent works focus on the mechanisms responsible for diversity patterns (speciation, extinction, dispersal) by including evolutionary approaches to the above ecological framework (phylogeny trees, fossil record, geomorphology of drainage basins). From an ‘applied’ point of view, I am also interested in evaluating the effects of environmental perturbations related to human activities on the vulnerability of species. Five broad axes can regroup my research activities:
