Community composition at the family level in (a) SAA and (b) GKS. Relative OTU abundance from left to right, in the control, the local and the foreign soil treatments determined at every sampling point (0, 6, 24, 72 h). Bacterial taxa that contributed most to the total number of sequences per sample were Gammaproteobacteria (Gamma), Firmicutes, Betaproteobacteria (Beta), Bacteroidetes (Bcdt), Alphaproteobacteria (Alpha) and Actinobacteria (Actino). Unclassified bacteria and other typical freshwater taxa that accounted for <3% of total sequence number were categorized as ‘Others’.
