2012 to 2016

Focusing on wild endofaunic bivalves, we will assess the role of environmental factors, more specifically of the ‘trophic settlement trigger’ (Toupoint et al. 2012, Ecology), on the recruitment dynamics of benthic invertebrates thereby integrating a new approach of the benthic habitats’ functioning: ranking habitats relative to the success of recruitment of model species.

2013 to 2016

The main objective of the B. Polar_Sclerarctic scientific project is based on the use of the skeletal parts of polar marine invertebrates as bioarchives of environmental changes of benthic marine arctic ecosystems. Methods of sclero–chronology and –geochemistry are used to reconstruct past variations of selected environmental parameters at different temporal (daily to century) and spatial (fjord to pan-arctic) scales by using two bivalve species, Chlamys islandica (Scala IPEV) and Astarte spp. (Sclerarctic Ec2co_INSU).

Team 7: Biodiversity & Macroecology

2014 to 2015

Les résultats de notre équipe sur cette espèce indiquent une très forte structuration génétique en Amazonie péruvienne, à des échelles spatiales bien plus réduites qu’en Amazonie brésilienne. Ces premiers résultats suggèrent l’existence de plusieurs espèces en sympatrie, avec des implications sur la gestion durable de l’espèce (conservation, pêche et pisciculture). Ce projet vise à clarifier la systématique et l’organisation populationnelle du Paiche en Amazonie péruvienne. Des échantillons de cette espèce sont collectés dans les principaux sous-bassins du Pérou.

Projet FINCyt au Pérou

Aplicación de marcadores moleculares (Barcoding y Metabarcoding) en la caracterización de peces ornamentales y de consumo de la Amazonía peruana y su aplicación en el monitoreo de la exportación, comercio y planes de manejo

Ce projet financé par le « Fondo para la Innovación Ciencia y Tecnología » est coordonné par Carmen Garcia Davila (IIAP) et Jean-François Renno (IRD- UMR BOREA, équipe 7). Il doit se dérouler de 2015 à 2017.

Team 2: Reproduction and development of aquatic organisms: evolution, adaptation, regulations


2009 to 2014

The key objective of the REPROSEED project is to support the capacity of European hatcheries to respond to an increasing demand for mollusc seed. Hatchery seed production of Pacific oyster (Crassostrea gigas) is already well established, while for other species (Mytilus edulis, M. galloprovincialis, Ruditapes decussatus, Pecten maximus) it remains limited due to market or biological bottlenecks.

Team 3: Adaptations to Extreme Environments


2014 to 2016

The ecotoxicological risks posed by deep-sea mineral extraction are complex and poorly known. Heavy metals, trace metals and Rare Earth Elements (REEs) phases may be subject to considerable alteration in the marine environment during the mining and at-sea processing of minerals. MIDAS will focus on issues related to the mining of minerals, where there is an urgent demand for information.

K4aqua- bacteria + K4
2012 to 2014

The objective of this project is to evaluate the potential of the antibacterial peptide K4 (FR 0709057) particularly active against marine Vibrio in aquaculture farms. Targeted investigations will test its safety on various marine organisms, its effectiveness in the context of controlled infection and its persistence in the environment.

Works were financed by the Regional Council of Basse Normandie.


2012 to 2014

The PEPTISAN project, labeled by the Pôle Mer Bretagne, aims to identify bioactive molecules for therapeutic uses from organs of the small spotted catshark. It is a joined project between the UMR BOREA, the Station Biologique de Roscoff, the Ecole Nationale Supérieure de Chimie de Rennes and the society KELIA of Saint-Malo. Its objectives are the characterization and preclinical development of molecules involved in the regulation of normal and pathological physiological functions based, in particular, on genomic data and the development of vector systems.

Team 6: Source and transfer of organic matter in aquatic ecosystems


Microcosms used during the degradation experiment for the PROCARDYA project
2013 to 2014

Planktonic prokaryotes are a key link in the transfer of organic matter (OM) in oceanic planktonic food webs and determine in part its transfer to the benthic realm. In return, the structure of prokaryotic communities appears to be directly related to the nature and bioavailability of OM, since it has been shown that certain phylotypes are specifically involved in the degradation of certain organic compounds, of different quality and origin. Coastal marine environments are characterized by a great diversity of primary producers.

Significant contamination by pesticides in some freshwater resources has been highlighted at the beginning of the 2000’s in Guadeloupe and Martinique Islands (French West Indies). Though they were banned from usage in the 1990’s, toxic and persistent molecules are still present in soils, with concentrations reaching 10 for the chlordecone (Kepone®), the most worrying organochlorine residue. Driven by water cycle, this terrestrial pollution is progressively transferred into surrounding aquatic ecosystems, affecting both water and biota.


2014 to 2016

Kelps, like higher plants, live in association with microscopic fungi called endophytes. In higher plants, these microorganisms colonize the organs without causing any damage and their beneficial role has been largely demonstrated in recent years. One of the striking features of this association is that it gives to the host a tolerance to abiotic and biotic stresses, especially against pathogens and herbivorous species. This mutualism is finely controlled by the production of structurally different metabolic factors, which origin and mechanisms of action remain to be explored.

Team 7: Biodiversity & Macroecology


2013 to 2015

Une large proportion des réseaux hydrographiques est composée de rivières intermittentes (RIs). Les RIs se caractérisent par une alternance dynamique d’habitats terrestres et aquatiques dans le temps et l’espace. Cette dynamique d’habitats génère une biodiversité unique incluant des espèces aquatiques, amphibies et terrestres. Les RIs offrent aussi de nombreux services écosystémiques, tels que l’atténuation des crues.
