Global changes affect species differently according to their sensitivity and adaptive potential, both of which depend on intrinsic traits that result from their evolutionary history. These effects can be modulated by extrinsic factors such as heterogeneity (e.g. micro-climates) or habitat fragmentation, as well as by the pressure of other potentially interacting human activities or indirect effects of environmental change, via changes in species interactions.
- to assess how past evolution can inform species adaptive potential
- to test whether macroevolutionary processes are linked to contemporary species responses
- to describe how species responses modify biodiversity patterns at the community level
While my previous works have
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.
