Distance-based redundancy analysis (db-RDA) of Bray–Curtis dissimilarly for a fungal ITS, b protist 18S rRNA gene, c archaeal 16S rRNA gene and d bacterial 16S rRNA gene phylotypes in DNA libraries, and e fungal ITS, f protist 18S rRNA, g archaeal 16S rRNA, h bacterial 16S rRNA in RNA libraries at Bog Forest (TSN2) and Peat Bog (TSN3) sites constrained by soil chemistry and climate variables. Model and axis significance determined by RDA ANOVA. Variable significance (bargraphs) was determined by PERMANOVA, shown as adjusted-R2 following PERMANOVA by categorical variables. p Values are denoted by asterisks (*p < 0.05, **p < 0.01, ***p < 0.001). TC total carbon, TN total nitrogen, TS total sulfur, CN carbon:nitrogen ratio, AP available phosphorus
