Appendix D. Post-hoc analyses of the effects of nutrient availability and water avialability × water heterogeneity interaction on the ratio of rot biomass in the 15–30 soil depth layer to that in the 0–15 depth layer in the heterogeneous treatments.

FIG. D1. Post-hoc analyses of the effects of (A) nutrient availability and (B) water availability × water heterogeneity interaction on the ratio of root biomass in the 15–30 soil depth layer to that in the 0–15 depth layer (RII index) in the heterogeneous treatments. Different lowercase letters indicate significant differences among nutrient (A) and water availability (B) levels (P < 0.05, Tukey’s HSD test after a three-way ANOVA). Data are means ± 1 SE (n = 48 and 24 for A and B, respectively).
