Fig. A1 The pairplot for annual height growth, sapling age and size, and relative light availability in Fagus sylvatica saplings with histograms on the diagonal, scatterplots with smoothers above the diagonal, and Pearson correlation coefficients with associated p-values below the diagonal. All variables were log10-transformed prior to analysis

Table A1 Results of GLM models used for variation partitioning between saplings’ age, size, and light availability explaining annual height growth of Fagus sylvatica saplings (Fig. 1). All variables were log10-transformed prior to analyses. Models with interaction term(s) were used for construction of Venn diagram (Fig. 2)
Model(s) without / with interaction term(s) / R2adjusted / pAge + Size + Light / Full factorial model / 0.702 / 0.715 / 0.001 / 0.001
