  abstract = {{P}lanktonic communities from {J}uan de {N}ova lagoon were submitted to a single exposure of diuron or naphthalene in triplicate outdoor 40-{L} mesocosms for 5 days. {T}he study followed the temporal changes of the assemblages by determining abundances and taxonomic level of microbial (heterotrophic prokaryotes, picocyanobacteria, heterotrophic protists and phytoplankton) and metazooplankton communities. {E}xposure to both contaminants did not result in significant changes in phytoplankton abundances. {M}icroscopic identification demonstrated the dominance of {B}acillariophyta (mostly {C}haetoceros tenuissimus) accounting for more than 95% of the microalgae detected in all mesocosms. {U}sing 18{S} r{RNA} metabarcoding, temporal changes in the proportion of eukaryotic operational taxonomic units ({OTU}s) were highlighted for most taxonomic groups. {D}iuron had no significant effect on the abundance of eukaryotic picoheterotrophs, ciliates, whereas naphthalene had a significant positive effect on heterotrophic prokaryotes. {M}etazooplankton was not significantly modified under contaminant exposure, except for copepods nauplii in presence of diuron. {M}ultivariate analysis indicated significant responses of communities linked to the experimental time and conditions. {T}he analysis also revealed a modification of the trophic relationships among communities over time, from a dominant multivorous food web after 48 h towards a reduced microbial loop after 120 h of experiment time.},
