Marine plankton communities are shaped by physical, chemical, and biological factors that influence the diversity and distribution of microorganisms as well as organismal interactions at different spatial and temporal scales.

The ECOMAP ambitions are:

1) to address questions over different time scales using the plankton genomic observatory  at Roscoff-Astan time-series combining high-throughput acquisition of advanced microscopic and multi-omics approaches (metabarcoding, metagenomics and metatranscriptomics) and fully capitalize on the strong expertise in taxonomy, imaging and functional diversity existing in the team and to a larger extent at the Station Biologique (e.g. Mer & Plongée and platform facilities).

2) to explore geographical distribution of marine planktonic species (diversity and functions) using large scales datasets such as Tara-Oceans, Malaspina, Tara-Polar Circle, Tara-Pacific, Tara-Microbiomes, Plankton Planet, Bougainville) and other dedicated oceanographic cruises (ANR Tonga, Moose network, ANR Green Edge, ANR Apero).

We combine culture-dependent approaches developed in close association with the Roscoff Culture Collection with meta-omics on the whole community and/or single-cell genomic data (i.e. single amplified genomes) to access the transcriptomes/genomes of uncultivated organisms and to obtain a more complete view of microbial community functions and dynamics. We also develop expertise databases such as the ones dedicated to protists [UniEuk, universal taxonomic framework for eukaryotes; PR2, 18S rRNA region; Aquasymbio, symbiotic associations], microalgae (PhytoREF, plastidial 16S rRNA), proteorhodopsin (PR)-containing photoheterotrophic bacteria (MicRhoDE, PR gene) and cyanobacteria (CyanoMarks, petBgene).
