Taxonomic profiles of the study sites. a Non-metric multidimensional scaling (stress value = 0.03) of replicate samples from both sampling sites, based on the total taxonomic profile. Low-sequenced samples are depicted with no fill color. b Taxonomic annotation of the metagenomic reads from the deep-sequenced samples, showing the relative abundance of prokaryotic phyla and orders. The 10 most abundant taxa are included in each graph; the remaining taxa have less than 1% and 1.1% relative abundance at the phylum and order level, respectively
