Improving our knowledge of the metal cycle in contrasting environments of the world ocean is absolutely necessary for a better understanding of the oceanic biogeochemical cycles of major elements (C, Si, N, S) and the biological carbon pump. LEMAR is internationally recognised in this field, in particular through our strong involvement in the GEOTRACES programme. […]
Le cycle du silicium est une thématique historique du LEMAR qui possède une forte visibilité internationale grâce à notre implication dans les programmes et consortium internationaux comme BioGeoSCAPES, IMBER, IODP, GEOTRACES, OPALEO, PAGES et SILICAMICS. Nous avons développé une approche transdisciplinaire, incluant la chimie, la biogéochimie, la paléo-océanographie, la biochimie, la physiologie, la biologie et, […]
Understanding the role and functions of organisms in their living environment is a major objective set by the DISCOVERY team. To simplify the representation of biodiversity and its role in the functioning of ecosystems, a functional approach to biodiversity is used by looking for groups of species, characterised by common biological traits (trophic mode, mobility, […]
In the ocean, trophic interactions between individuals are still mainly represented in a predator-prey pattern. However, meta-analyses of taxonomic co-occurrences, made possible by advances in molecular biology, suggest that many planktonic organisms are involved in complex interactions ranging from facultative predation to symbiosis to mutualism. While these relationships appear to be the rule rather than […]
The ocean dynamics is structured on scales ranging from a thousand kilometers, a few meters, through the tens / hundreds of kilometers.
