| Summary: | Covering: up to 2017
Chemical mediation regulates behavioral interactions between species and thus affects population structure, community organization and ecosystem function. Among marine taxa that have developed chemical mediation strategies, gastropods belong to a diverse group of molluscs found worldwide, including species with a coiled, reduced or absent shell. Most gastropods use natural products to mediate a wide range of behaviors such as defense, prey location or interactions with con- and hetero-geners. Their chemically defended diet, such as cyanobacteria, algae, sponges, bryozoans and tunicates, provides them with a considerable opportunity either as shelter from predators, or as a means to enhance their own chemical defense. In addition to improving their defenses, molluscs also use prey secondary metabolites in complex chemical communication including settlement induction, prey detection and feeding preferences. The assimilation of prey secondary metabolites further provides the opportunity for interactions with conspecifics
via
diet-derived chemical cues or signals. This review intends to provide an overview on the sequestration, detoxification, and biotransformation of diet-derived natural products, as well as the role of these compounds as chemical mediators in gastropod-prey interactions.

| Bibliography: | Louis Bornancin, born in 1988 in Bordeaux, France, received his B.Sc. in Chemistry from the University of Bordeaux in 2009 and his M.Sc. in Chemistry from the University of Limoges, France, in 2011. He joined the research group of Dr Bernard Banaigs and Dr Isabelle Bonnard at CRIOBE (USR 3278 EPHE-CNRS-UPVD PSL) in 2013 and received his PhD in 2016. He has been a teaching and Research Assistant at CRIOBE since October 2016. His research focuses on the chemistry of natural products and the role of secondary metabolites in the structuring and functioning of marine ecosystems. Suzanne C. Mills has been an assistant professor at CRIOBE, USR 3278 EPHE-CNRS-UPVD PSL in France since 2006. Suzanne obtained her PhD from the University of East Anglia, UK, on the evolutionary ecology of a fish-mussel symbiosis followed by postdoctoral research at the University of Jyvaskyla, Finland, and the University of California Santa Cruz on selection mechanisms that maintain genetic variation. Her research focuses on the evolutionary and ecosystem consequences of global change, the hormonal and chemical mechanisms that mediate these impacts, and the mechanisms (phenotypic plasticity and maternal effects) by which organisms can adjust to anthropogenic stressors. Bernard Banaigs received his PhD in Organic Chemistry (1983) at the University of Montpellier, France, and carried out postdoctoral studies at the Scripps Institution of Oceanography (Bill Fenical) and at the University of Perpignan, France, with the support of the French Foundation for Medical Research. In 1986 he became a Senior Research Scientist at the French National Institute of Health and Medical Research (INSERM), based at the University of Perpignan. He has considerable expertise in the Chemistry of Marine Natural Products and his research, at CRIOBE (Center de Recherche Insulaire et Observatoire de l'Environnement), focuses on the discovery of bioactive natural products from marine organisms, and studying their role in biological interactions. Isabelle Bonnard obtained her PhD (in 1996) from the University of Perpignan after specializing in Marine Chemistry at the University of Brittany. In the continuity of her thesis work on the isolation and structural determination of marine cyclic lipopeptides with a cyanobacterial origin, Isabelle joined the team of Prof. Kenneth Rinehart, at the University of Illinois at Urbana-Champaign (USA), for a postdoctoral fellowship. Isabelle was appointed as a lecturer in 1998 at the University of La Réunion, developing the chemistry of natural products from diverse marine organisms from the Mascareign Area. Isabelle moved to the University of Perpignan in 2004 and joined CRIOBE, focusing her research interests on chemical ecology, chemical mediation in the marine ecosystem and environmental metabolomics.
