Through the various research programs, the studies which I conduct on seaweeds are declined according to three levels: the coastal ecosystem, the communities and the organism respectively providing knowledge on the functioning of ecosystems and the impacts of the anthropic activities, on the dynamics of macroalgae, on the ecophysiology, on algal morphogenesis, and also algal molecules. Two main axes are developed:
The regional problem of mass stranding of seaweeds led me to develop an environmental theme on the use of macroalgae as bioindicators of the quality of marine environment. Because of the symptoms of the impact of human activities in the coastal marine environment and in particular of nitrogen inputs, I try to use seaweeds as a tool to assess the quality of coastal waters in order to understand the genesis of accumulations summer affecting some coastal areas, the monitoring of the isotopic signatures (δ15N) in algae allowing to identify the origin of the anthropisation on the coastal ecosystem (urban/agricultural) and to map the sensitive coastal areas. Ultimately this research program could be used as a support of biomonitoring in order to define and set up a system of evaluation of the littoral quality of coastal waters by seaweeds in Lower-Normandy.
Keywords: seaweeds, plant biotechnologies, in vitro culture, ecophysiology, benthic seaweed communities, bioindication, quality of coastal water, (δ15N).
