Marine chimiodiversity knowledge and utilization


Team leader : Professeur Laurent Barillé

Coastal areas are the most industrialized and urbanized areas on Earth. More than 50% of the world's population lives in a narrow zone within 60 km from the shore. Coastal and estuarine zones, though directly exposed to anthropic activities, host a wide and rich variety of organisms, vital for the functioning of ecosystems and associated socio-economical uses.

Our team focuses on two themes: MERL and ContaMar.

Mudflat Ecology Research Lab (MERL): from physiological mechanisms to hyperspectral remote-sensing.
We study benthic ecosystems by analyzing the i) physiological mechanisms of keystone organisms, ii) transfers and flux between trophic levels (primary producers, filter-feeders mollusks and wading birds), iii) spatial interactions at the scale of the ecosystem using space and airborne remote-sensing.
Group leader: Laurent Barillé, Université de Nantes

ContaMar : response of trophic networks to emerging contaminants (nanoparticles, endocrinal perturbations ...)
We study the perturbations caused by emerging contaminants (endocrinal perturbations, nanoparticles ...) over a biologically- and ecologically-consistent range of scales.
Group leader: Catherine Mouneyrac, UCO


Summarizing scheme of scientific themes studied by our team, showing the variety of biological scales and of processes investigated.


Our team develops tools and methods to better understand the environmental status of coastal ecosystems, and to assess the degree of risk affecting near-shore environments. Our approach integrates a large variety of biologically scales, from molecules to population dynamics. Dedicated efforts are notably performed to study keystone and sentinel species.
