Missions

Within the EABX unit, the FREEMA team (Functioning and Restoration of Estuarine Ecosystems and Amphihaline Migratory Populations) carries out research on the understanding, characterization and evaluation of the responses of continental aquatic biodiversity to the combined impacts of climate change, environmental stresses and anthropogenic pressures.

Biodiversity is apprehended at different levels of organization (individuals, populations, communities and ecosystems) around two main objects of study: populations of amphihaline migratory fish (AMF) and estuarine ecosystems (EE).

Fields of research

Firstly, our research focuses on characterizing and assessing the status and viability of AMFs and EEs in the face of global change. In this respect, it relies on work aimed at better understanding the current dynamics and functioning of biodiversity around our objects. This involves work in ecology (essential habitats, dispersal, migrations, sensitivity to temperature or hypoxia, behavior, phenotypic plasticity), ecotoxicology (bioaccumulation and effects of contaminants, work carried out in partnership) and population dynamics.

Then, on the basis of our knowledge and expertise, our investigations aim at describing and understanding the evolution of AMFs and EE in response to global change, in order to better assess the stability and resilience of populations, communities and ecosystems.

Skills

To address these different issues, we have solid expertise in various fields of biology and ecology:

• population ecology, conservation biology, movement ecology, rehabilitation ecology, behavioral ecology, trophic ecology, fisheries ecology, restoration ecology, bioindication, ...

• statistical modeling, trophic modeling, population dynamics

• ecotoxicology, genetics, ecophysiology and socio-economics (in partnership)
