Figure 3. SMX-driven shifts in sediment bacterial communities. (IMAGE)
Caption
(a) PCoA (Bray-Curtis) showing community separation by SMX (PERMANOVA, R=0.4979, p=0.001). (b) ACE index (richness) response to SMX concentration. (c) Phylum-level composition highlighting Proteobacteria, Actinobacteria, and Chloroflexi. (d) Phylogenetic cladogram of SMX-sensitive OTUs (LEfSe; p<0.05). (e) Heatmap of SMX-responsive genera; color = log-fold change vs control.
