Relationship between NIR reflectivity and climate for the mantle and crown. The data are separated by the arbitrary size of 100 g (<100 g: left panels, 33 species; >100 g: right panels, 57 species) to facilitate visualisation of the interaction between environmental PC2 and body mass, but body mass was treated as a continuous variable in statistical analyses. Each point represents the average value per species and the standard error in both axes; colour represents the species’ habitat. Trend lines were predicted using a phylogenetically controlled model that included environmental PCs, UV-visible reflectivity and a random phylogenetic tree
