Metadata for each ARMS retrieved. Pearson correlation between explanatory variables obtained from remote sensing data and benthic surveys. Significance values of the differences of satellite derived products and percentage cover of ecologically meaningful benthic structures between regions. The 10 highest averages of the OTUs influencing differences in community structure obtained using a Simper analysis with 999 permutations and their respective taxonomy. Venn diagram showing the number of operational taxonomic units (OTUs) unique to the central region and Al Lith (S1, S2, and S3) and Farasan Islands reefs (S4 and S5) and shared between them using a random subsample of 9 ARMS of the central region. CART models using regression tree to distinguish critical breakpoints in the abundance of the OTUs that significantly contributed to the dissimilarities observed.
