Viral community structures and their environmental drivers. a Community compositions (family level) of lytic and temperate viruses in all samples. b, c Venn diagrams display the number of unique and shared (lytic and temperate) vOTUs in the three habitats. d, e NMDS of (lytic and temperate) viral communities based on Bray–Curtis dissimilarity. f The left heatmap shows the Spearman’s correlations between (lytic and temperate) vOTU numbers and environmental factors (Prokaryote: prokaryotic richness). The right heatmap shows the Mantel correlations between Bray–Curtis distance of viral community structures and Euclidean distance of each environmental factor (Prokaryote: Bray–Curtis distance of prokaryotic communities). Color bars on the top of the heatmaps indicate the viral lifestyles and habitats, respectively. The number of asterisks denotes the statistical significance level (* P < 0.05 and ** P < 0.01). C/N, ratio of carbon to nitrogen; Temp, temperature; Chl a, chlorophyll a; FL, free-living; PA, particle-attached; SE, sediment
