For 15 years, our studies have contributed to the understanding of the functioning of Mediterranean coastal marine ecosystems and have worked towards their conservation in collaboration with managers. From the definition of scientific issues to the statistical processing of data, including their collection in-situ via adapted experimental designs, we manage and carry out these research programs, in conjunction with our local, national and international scientific and institutional partners, both public and private. We devote a particular effort to share and transfer our expertise, in the form of scientific publications, and recommendations but also through our participation as members of scientific boards and commissions.
