Fig. 1: Variation in bacterial community composition of the three soils studied.

A Venn diagram of the number of shared and unique bacterial amplicon sequence variances (ASVs) within each soil. B Non-metric multidimensional scaling (NMDS) of soil communities at the ASV level under water-only conditions, as well as under exudate and litter C addition. Distances of points within NMDS are based on relative abundances of ASVs.
