Fig. 6 — Colour indicates soil treatment (control = grey, 1 year = light blue, 10 years = blue). Left panels show boxplots representing the Bray-Curtis dissimilarity index between drought treatments and control for archaea/bacteria (F = 44.969, p = 0.0005, n = 4), fungi (F = 32.86, p = 0.012, n = 4) and AMF (F = 23.002, p = 0.003, n = 4). The right panel shows boxplots representing the soil multifunctionality index (calculated by a wide set of soil parameters including enzymatic activities, soil C and nutrient stock, microbial biomass C, N and P and root biomass productivity) grouped by treatment (F = 5.514, p = 0.027, n = 4). Letters represent results from two-sided Tukey HSD post hoc test. Box centre line represents median, box limits the upper and lower quartiles, whiskers the 1.5x interquartile range, while separated points represents outliers.
