AQUAECO team « Aquatic ecology and global changes »


The work of the AQUAECO (Aquatic Ecology) research group aims at understanding the processes that structure the composition and the functioning of aquatic populations and communities in the general context of global changes. Based on theoretical approaches aiming at understanding the relationship between biodiversity and ecosystem functioning, our research also aims to provide applied insights to maintain the multiple services provided by aquatic organisms and ecosystems to human societies.
To quantify the current and future consequences of global changes on biodiversity, it is of upmost importance to identify the determinants of biodiversity and to understand how global changes might affect biotic interactions among organisms and ecosystem processes. These two approaches are investigated by AQUAECO through the analyses of the intra- and inter-specific facets of biological diversity across different spatial and temporal scales.
The AQUAECO research group focuses its investigations on the impacts of climate change, habitat fragmentation, biological invasions and the overexploitation of resources, using freshwater fishes as model organisms. We are ultimately aiming to provide management suggestions to restore and conserve freshwater ecosystems.
AXE 1 : Determinants of biodiversity
Here, we aim at determining the drivers of biodiversity by investigating the spatial and temporal dynamics of aquatic fauna. We focus our work on the factors involved in the evolutionary diversification of species, and the dispersion and the extinction (natural and human-driven) of freshwater fish based on dynamical and multi-scale approaches to assess species distribution and extinction and diversification rates.

AXE 2 : Biodiversity, biotic interactions and ecosystem processes
Here, we aim at understanding how non-random changes of biological diversity caused by global changes affect the relationship between biodiversity and ecosystem functioning. We include in our investigation the interactions among organisms (e.g. predation, competition, parasitism) and explicitly account for the intra- and inter-specific facets of biodiversity to link ecological and evolutionary processes.
