Differences in bacterial community structure and composition between coalesced and reference communities. Weighted UniFrac distances between coalesced and reference communities during the step 2 experiment are represented for the control (A) and heat-shock (C) (mean ± s.e.). Different letters above the bars indicate significant differences according to Nemenyi’s all-pairs comparison test (p-value < 0.05). The Venn diagrams show the number of shared/unique OTUs between the coalesced and references communities for the control (B) and heat-shock (D) at high (d1) and low densities (d2)
