Fig. 5: Variation in the crown architecture along gradients of tree cover, aridity, and wind gust speed.

Points are species-level estimates of size-standardized a–c tree height (HRESID, n = 1910 species), d–f crown diameter (CDRESID, n = 1313 species) and g–i crown aspect ratio (CARRESID, n = 1309 species). Fitted lines correspond to phylogenetic generalised least squares model predictions generated by keeping all other predictors fixed at their mean values. Negative values of HRESID, CDRESID, and CARRESID indicate species that are shorter, with narrower crowns and smaller crown aspect ratios than expected given the size of their stem, while positive values denote the opposite. Values of tree cover, aridity index and wind gust speed represent are means calculated across all individual trees of a given species. Note that the aridity index was log-transformed and that larger values correspond to drier conditions.
