Principal coordinate analysis plot of weighted UniFrac distances based on 16 S rRNA gene (DNA) and 16 S rRNA (RNA) from the surface layer of each incubation. The 0_Closed_6h_DNA sample was deemed an outlier due to contamination and was therefore not included in this analysis (see Methods for details). Permanova identified a significant difference between open and closed conditions (p < 0.001), but not between DNA and RNA. The ellipses represent the 95% confidence interval. 0, 50, and 100 denotes distance along the transect in cm.
