Fig. 4
Predicted growth response to annual climate (from 1990 to 2010) under contrasted stand basal areas. Predictions are obtained from B and C estimates in Eq. 1. For a given year i: Prediction i = B i + Ci × ln(SBA), where SBA is stand basal area. Positive and negative years correspond to years with high growth and low growth, respectively (see main text). Similar letters indicate a significant difference at the 5 % probability level in a Wilcoxon-Mann-Whitney test. No significant differences were reported for positive years
