Fig. 3From: Soil microbiomes with distinct assemblies through vertical soil profiles drive the cycling of multiple nutrients in reforested ecosystemsSimilarity of soil bacterial, archaeal, and fungal communities between arable land and reforested soils (a), radii around the tree (b), and soil layers (c). Community similarity was calculated based on 1—[dissimilarity of the Bray–Curtis distance metric]. The lines denote the least-squares linear regressions across soil depth, with their 95% confidence intervals (gray-shaded areas). *P < 0.05; **P < 0.01; ***P < 0.001Back to article page
