The relationships between relative abundances of 15 dominant bacterial groups and soil pH. Linear regressions were used to test the relationship between the taxa's relative abundances and pH. To avoid the possible confounding substrate influence below pH 4.5, due to impeded plant growth below this pH (see Discussion section), only data points between pH 4.5 and 8.3 (filled circles) were used for the analyses, and data points below pH 4.5 (open circles) were excluded. Panels (a)–(o) depict the relationships between specific bacterial taxa as defined in each panel.
