Taxonomic composition of the gut microbiome in Atlantic cod. Relative abundance of (a) bacterial phyla and (b) OTUs. Colors represent the 11 phyla (a) or the 20 most abundant OTUs (b) in cod. Unclassified sequences (a) and remaining OTUs (b) are merged into “Unclassified” and “Other” categories, respectively. Legend names are listed according to the total size of the taxonomic unit, and asterisks indicate OTUs differentially abundant between the lower and upper exposure groups
