Abbreviations: CCA, crustose coralline algae; OTU, operational taxonomic unit. Number of OTUs found with each host as assigned sporadic and stable and the percentage of total OTUs that these groups make up of the total number of OTUs in each community. The median relative abundance of OTUs in stable and sporadic groups (±interquartile range) and mean Shannon diversity (H'±s.d.) are also included.
