Correlational co-abundance networks of water microbial community. Water microbial community networks displayed fragmented interactions, over time and between treatments — the topology of water microbial encompassed sub-networks disconnected in small independent hubs. The number of independent hubs was the highest in Control network at T0 and T3, at T3 in CC, and it was always intermediate in CV network (see the Supplementary Table 3). These networks are based on significant Spearman coefficients and were constructed using R scripts and Cytoscape software
