  1. All extant operational taxonomic units labeled in Figure 2 (and thus influential in distance-based redundancy analysis, as well as significant indicator taxa for their respective surface type) were related to their closest known bacterial isolate using 16S rRNA sequences in the NCBI Bacteria & Archaea Isolate Database. Source environments are from each isolate’s respective published source environment. *Unadjusted P value < 0.05. **Closest known isolate 89% similar.
