Our results notably showed that eukaryotic communities trapped in seafoams were different from communities in adjacent seawater. In particular, seafoams were rich in ASVs affiliated to saprobes and parasites compared to seawater, with a terrestrial origin for most of them. jeu., 26 juin 2025 17:06:36 +0200 jeu., 26 juin 2025 17:07:05 +0200 https://www.peren-revues.fr/annales-sgn/2668
