Summary

BACKGROUND: Estuaries are complex ecosystems linking river and marine environments, where microorganisms play a key role in maintaining ecosystem functions. In the present study, we investigated monthly 8 sites at two depth layers and over a one-year period the bacterial and eukaryotic community dynamics along the Seine macrotidal estuary (Normandy, France). To date, the taxonomy of the microbial diversity present in this anthropized estuary remains elusive and the drivers of the microbial community structure are still unknown. RESULTS: The metabarcoding analysis of 147 samples revealed both a high bacterial and eukaryotic diversity, dominated by Proteobacteria, Bacteriodota, Actinobacteriota and Bacillariophyta, Spirotrichea, Dinophyceae, respectively. Along the estuary we only detected s
