Partner Description

The CEREEP-Ecotron IDF is a joined unit of services, in partnership with CNRS and ENS ( It is dedicated to experimental ecology, with technical platforms of national importance, and is also used for teaching and biodiversity observatories. The centre coordinates since 2011 the PLANAQUA equipment (“Plateforme nationale d’expérimentation en écologie aquatique”) funded by the Equipex program (“Equipements d’excellence”). PLANAQUA consists in a fully integratedexperimental platform of aquatic microcosms, mesocosms and macrocosms. The centre belongs to the CNRS national network of ecological experimental stations (ReNSEE), which guarantees (1) a national framework, (2) permanent support, and (3) a platform for exchange of technical and administrative skills. It is networked with other platforms inside the “Infrastructure nationale en biologie-santé” AnaEE-France, itself involved in the elaboration of the Infrastructure AnaEE-Europe (“Structuring infrastructures for the ANalysis And Experimentation on Ecosystems”), in the preparatory phase of ESFRI FP7 program.

Sarah Fiorini (f, PhD 2009 oceanography) is chief engineer responsible of the laboratory facilities and microcosm platform of PLANAQUA. Expertise regarding effects of ocean acidification and global warming on phytoplankton ecophysiology. Strong experience on microcosm experiments on marine and freshwater microorganisms focusing on biochemistry, biology, ecology and organisms interactions. Conception and technical development of the aquatic microcosm facilities of PLANAQUA, dedicated for use in the climatic rooms of the Ecotron IDF.
