Biodiversity Metrics for Viruses & Bacteria. a, c Richness, diversity (Shannon’s H), and evenness (Peilou’s J) of smoker (blue bars) and nonsmoker (red bars) viral and bacterial communities, respectively. b, d PCoA of Bray-Curtis distances between viral and bacterial communities, respectively. Smoking status was factor fit to the PCoA plot, with blue and red ellipses represents smoking and nonsmoking statuses, respectively
