MOESM3 of Convergence of soil microbial properties after plant colonization of an experimental plant diversity gradient

Additional file 3: Figure S2. Plant colonization effects on soil microbial properties. Mean values with confidence intervals of basal respiration [µg O2 g−1 soil dry mass h−1] (a) two and (c) five years, and soil microbial biomass [µg C g−1 soil dry mass] (b) two and (d) five years after colonization by plant species. Circles display basal respiration and soil microbial biomass with resident plant species of weeded subplots, respectively, and open circles display basal respiration and soil microbial biomass with resident plant species plus colonizing plant species of non-weeded subplots, respectively.
