Figure S2. Empirical trait data
coverage for species included from Open Nahele (n=142) (a), for four
plant traits specific leaf area (SLA; mm2/mg), wood
density (g/cm3), maximum plant height (plant height;
m) and leaf nitrogen content (Leaf Nmass; mg/g). Density distribution of
empirical trait data versus imputed trait data (b) using
phylogenetically informed imputation based on random forest algorithm.
Letters on each density plot of a trait correspond to Kruskal-Wallis
results (alpha level 0.05). Note that we did not find significant
differences between empirical and imputed traits, as both groups of
traits shared the same letter. The prediction error of the random forest
algorithm from phylogenetic relationships using out-of-bag error (OOB)
is also displayed.
