Evolutionary ecology and adaptation

Representatives : Jean-Dominique Durand (IRD) and David McKenzie (CNRS) BACKGROUND Anthropogenic pressures and the resulting climate change are extremely recent evolutionary forces whose effects on marine biodiversity are considered as major. Our ability to model and predict these effects (...)
Individuals, populations and habitats

Representatives : Claire Saraux (Ifremer) and Yann Tremblay (IRD) BACKGROUND Marine ecosystems are spatially structured as a result of many ecological processes (with abiotic and biotic forcings) taking place at various spatial and temporal scales. The stakes are therefore (i) to understand (...)
Communities’ dynamics and functioning

, par Vidal Ayouba Isabelle

Representatives : David Mouillot (UM2) and Yunne-Jai Shin (IRD) BACKGROUND In a context of global change, it is necessary to understand and predict the trajectories of species communities in terms of structure and functioning, to better protect biodiversity and maintain the associated (...)
Contaminants, future and answers

, par Vidal Ayouba Isabelle

Representatives : Christophe Leboulanger (IRD) and Jehan-Hervé Lignot (UM2) BACKGROUND Contaminants from natural and / or anthropogenic origin potentially toxic to organisms
 constitute a pressure that could permanently affect marine ecosystems. The presence and effects of these contaminants (...)
Sustainable aquacultures

, par Vidal Ayouba Isabelle

Representatives : Emmanuelle Roque (Ifremer) and Eric Fouilland (CNRS) BACKGROUND Since 2008, the European policy increasingly supports aquaculture sectors (shellfish, fish and algae farming) for both social and economic reasons, but also for patrimonial reasons.
The challenge is to develop a (...)
Coastal systems of multiple uses

, par Vidal Ayouba Isabelle

Representatives : Rutger De Wit (CNRS) and Vincent Ouisse (Ifremer) BACKGROUND The coastal area provides important ecosystem services to companies and is particularly affected by global changes (e.g. population pressure, pollution, habitat deterioration, rising sea levels). Coastal ecosystems (...)
Ecosystem approach to fisheries

Representatives : Nicolas Bez (IRD) et Olivier Maury (IRD) BACKGROUND Marine ecosystems are experiencing major changes (climate, overfishing, loss of biodiversity, pollution), in a context of increasing global demand for food and economic globalization. The extent of changes and the (...)

MARBEC MARine Biodiversity, Exploitation and Conservation, is a research unit which includes the staff of 4 organizations: IRD, IFREMER, UM and CNRS. Its objective is the study of marine biodiversity in lagoon coastal and offshore ecosystems, at different integration levels, molecular, individual, population and community aspects and the way humans use this biodiversity.
