FIGURE 7.

Co-occurrence network analysis based on Bray-Curtis dissimilarity metric (max distance = 0.5, Order level) for water samples from Trial 3 (n = 3 tanks per treatment and day, total of 18). Taxa that change in the same way share an edge; nodes that have edges occur in the same proportions and in the same samples. Darker blue circle nodes indicate taxa that occur in the Control significantly more than Treated water samples. White nodes have equal occurrence in treated and control water samples. Darker red diamond nodes indicated taxa that occur in the Treated significantly more than Control water samples.
