Fig. 3: Multivariate metabolic profiles of freshwater benthic bacterial communities on tiles under ambient (A; green symbols), elevated nutrients (N; yellow symbols), elevated salinity (S; blue symbols) and combined elevated salinity and elevated nutrients (SN; purple symbols) treatments, 1 day (circles), 7 days (triangles) and 30 days (squares) after tiles with established microbial communities were deployed in the treated ponds.

PCA ordination on Euclidean distances calculated on maximum slopes of OD590 values for each plate. PCA 1 explains 45% of variance and PCA 2 explains 11% of variance. Ellipses represent a confidence interval of 0.8.
