Coastal areas are highly productive ecosystems. Their production supports diverse human activities and as a consequence high population density. Because of such features, coastal areas are at the vortex center of strong social/economical stakes and pressures. It is thus important to study coastal ecosystems in order to better 1) characterize the complexity of their food-web, 2) characterize the functional biodiversity and to define its role from the biological community to the ecosystem scale, 3) quantify the effects on their functioning of both natural (global climate change framework) and human (biological resources exploitation framework) disturbances. Such work has become essential in order to efficiently deal with the fundamental actual questions of the assessment of the ‘environmental quality’ and of the sustainability of social/economical activities (protection of species and habitats, maintenance of functional biodiversity, rehabilitation of areas of biological interest, prediction of global change/human impacts, etc.).
The DYFEA team develops the necessary knowledge and tools to help at the joint, reasonable and sustainable management of coastal resources. DYFEA uses various approaches including laboratory and field experiments, multivariate analysis and mathematical modeling. The research activities of DYFEA especially include and develop the complementary expertises from recent hirings :
(1) The trophic functioning of coastal ecosystems ;
(2) Functional traits : from coastal biological communities to ecosystems ;
(3) Effects of human activities and climate change disturbances on coastal ecosystems.
