Coefficients of the generalized linear mixed-effects models (standard error in brackets) for predicting post-fire <i>Q. suber</i> responses.

(1) Model coefficients: β0, intercept; BT, bark thickness (cm); Ex, exploited for cork (yes vs. no); DBH, diameter at breast height (cm); BT*Ex, interaction between BT and Ex; PCH, maximum bole char height expressed as percentage of tree height (%); NA, means that the variable was not tested because it was not available in all sites; standard error of each coefficient is shown in brackets; (2) Significance of coefficients for the variables refers to the change in explained variance (*P<0.05; †P<0.01; ‡P<0.001) and for categorical variables refers to the comparison with the first category. (3) Models evaluation: AUC, area under the ROC curve; R2, Nagelkerke R2. SHAPE.
