Fig. 2: The macrodiversity of soil viral communities.
From: Response of soil viral communities to land use changes
a Boxplot showing Bray–Curtis dissimilarity of viral communities of intra-sites (between the corresponding community of iVLPs and eVLPs, n = 25) and inter-sites (between different sample sites, n = 300). The minima, maxima, center, bounds of box and whiskers in boxplots from bottom to top represented percentile 0, 10, 25, 50, 75, 90, and 100, respectively, the difference between different zones was tested using the two-sided Wilcox.test, ****p < 0.0001. The exact p value is 1.6e-15. b Principal coordinates analysis (PCoA) of viral community structures, as derived from reads mapping to 59,626 vOTUs and Bray–Curtis dissimilarities; each point is one sample, triangle indicated extracellular (Non_mitomycin_C) and circles indicated intracellular (mitomycin_C treatment) viral community. The analysis of similarity (ANOSIM) statistics considered viral community composition grouped by habitat and treatment. The land use zone AG represents agricultural areas including paddy and vegetable field; UG represents urban green space including park and road verge; FO represents forest. Ellipses in the PCoA plot are drawn around the centroids of each zone at 95% (inner) and 97.5% (outer) confidence intervals. The statistical test used was two-tailed. Source data are provided in the Source Data file.
