The distribution of occurrences (presence/absence observations) for OTUs sampled and sequenced from the surficial sediments of the three triclosan modified treatments. 1 Supplementary Table 1. Summary BLAST and taxonomic allocation results of the two sequenced reference samples obtained from Fundulus heteroclitus. Nearest taxonomic level is lowest common taxonomic level between the highest BLAST hit and Fundulus heteroclitus. Final corrected taxonomic assignment refers to the final assignment given to the OTU subsequent to phylogenetic tree visualization and Linnaeus Blasts. uk = unknown.
