FIGURE 6.
Principal coordinates analysis (PCoA) conducted on ASV abundances showing the dissimilarity of heterotrophic bacteria compositions between samples in (A) Lake Agawam and (B) Lake Erie. Color denotes the sample size fraction (MCA, FL, and W) and the color gradient indicates season in Lake Agawam and transect in Lake Erie. Percent’s listed on the axes represents the percent variation explained. (C–E) Show the environmental parameters that were significantly correlated to community dissimilarity, with color gradient indication environmental parameter value. (C–E) Represent Lake Agawam and (F) represents Lake Erie. Circles indicate significant clustering of the MCA communities.
