Maximum water shortage and yearly transpiration simulated by PDG-Arena for 13 mixed stands. Maximum water shortage is defined as the yearly maximum difference reached between the current and full useful reserve. Three types of inventories were used: regularized monospecific inventories (RM, in very light blue), regularized inventories with species interactions (R, in light blue) and original inventories (O, in dark blue). Two-sided Wilcoxon signed rank test was used (*: p-value < 0.05, ***: p-value < 0.001)
