Global changes are affecting simultaneously biodiversity, ecosystem functioning and their complex interactions but our ability to determine how ecosystems may respond to such changes is limited. Understanding the consequences of human activities is crucial to link theoretical and applied ecology at the individual, population, community and ecosystem levels.
Our lab aims to understand the mechanisms linking a non-random source of alteration of biodiversity (biological invasions) to freshwater ecosystem functioning. We based our work on trophic ecology (stable isotope ecology), using trophic interactions as a currency to link the structure of biodiversity to ecosystem functions.


SOLAKE – This project aims to quantify the ecological impacts on biodiversity and ecosystem functioning of floating photovoltaics in lakes.
