Significance of predictors of functional divergence in Juniperus thurifera, represented with p values from Generalised Dissimilarity Models (GDM). Functional traits (rows) and predictors (columns) are as in Fig. 2. For each functional trait, a GDM including all predictors was performed in each study plot of mature (Mat), transition (Trn) and expanding (Exp) forest stages. The number of plots per forest stage is 5 (Mat), 6 (Trn) and 6 (Exp), but p values of predictors are only shown for plots with significant (dark blue dots; p < 0.05) or marginally significant (light blue dots; 0.05 < p < 0.1) effects. For each forest stage, predictors are shadowed in grey when they show significant or marginally significant p values in two or more plots. Vertical axes are in square-root scale to improve display
