My scientific activity focuses on the  impacts of global changes on biodiversity. In that context, I am particularly interested in stream ecosystems and fish assemblages, highly  vulnerable to climate change  and human pressures. While my previous works have mainly addressed the potential impacts of future climate changes on fish species distribution, my current scientific activity is designed to understand the ability of species to shift their ranges in response to contemporary global changes. By analyzing species range shifts over last decades, my current works combine trait-based and phylogenetical approaches, seeking to identify the mechanisms involved in climate-induced range shifts and to better evaluate species vulnerability to future environmental changes.

The main objectives of my works are:

  • to assess how past and contemporary evolution can inform species adaptive potential 
  • to test whether macroevolutionary and microevolutionary processes are linked to contemporary species responses
  • to describe how species responses modify biodiversity patterns at the community level
  • to test whether biodiversity patterns are linked to species adaptive potential.
