Fluctuations of the digestive microbiota between consecutive dates over 1 year. Figure S3. Relative abundance and taxonomical composition of the digestive microbiota at the phylum level for abalone fed on Palmaria palmata (A), Laminaria digitata (B), Ulva lactuca (C), and Saccharina latissima (D). Figure S4. Ecological patterns of the digestive microbiota explained by a model of contextual parameters. Figure S5. Experimental site and set up. Figure S6.
