FIGURE 11.

Correlation relationship with the top 30 genera comprising microeukaryotes and target algae (A. catenella), based on significant Spearman rank correlation coefficients. The deep red nodes represent target algae (Eg01, the bloom-forming species A. catenella); green nodes indicate bacterial taxa; yellow nodes indicate archaea; and the light red nodes indicate eukaryotes. Circle size reflects the number of connections the OTUs has with other OTUs. Red bold lines indicate strong positive correlations and red dotted lines indicate positive associations; black bold lines indicate strong negative correlations, black dotted lines indicate negative associations.
