Predicted trait distributions (black dots) from the interactions between mean annual temperature (MAT) and pH, and between mean annual precipitation (MAP) and pH for specific leaf area (SLA) in a 3D plot. We represented the effects of interactions using the standardized parameter estimates of MAT and MAP (Fig. 3). Predictions were calculated for acidic, slightly basic and basic conditions (pH = 5.5, pH = 7.8, pH = 9.3, respectively). All other standardized parameter estimates were fixed at their mean value. The colours of the predicted planes change from blue (low values of the moments) to red (high values).
