Team 6: Source and transfer of organic matter in aquatic ecosystems

research boat

General topics

The topics for which we have developped an extensive expertise focuses on the study of the functioning of aquatic ecosystems through the combined use of isotopic, biochemical and sclerochronologic markers. Our expertise responds to important issues: those of the origin, fate and quality of organic matter for optimal characterization of the functional state of an aquatic ecosystem. We tackle these studies through two main approaches: 1) the responses of food webs under anthropogenic pressures and 2) qualitative changes affecting transfers at different levels of organic matter.
