FIG 5.

Principal coordinates analysis (PCoA) of Bray-Curtis dissimilatory based on the relative abundances of all unique sequences across sessile samples and three effluent time points of each column (before the columns were sacrificed for sessile community harvesting). (a) PCoA plot showing observations from all the time periods. (b) Facet plots of the same PCoA showing separate plots for different time periods. The PCoA plot has been segregated based on late- and early-harvesting time periods of treated and nontreated columns. Early harvesting represents columns harvested during the 1st, 2nd, and 3rd harvest, whereas late harvesting represents columns harvested during the 4th harvest. Details of columns and time periods are present in Table 1.
