Extended Data Fig.1: Larger differentiation in aboveground than fine-root traits.

Proportion of variance explained in PERMANOVA analyses by differences among groups of species (families and biomes, see Carmona et al.3 for details), considering the whole functional space (Total), the aboveground and fine-root planes, individual components of the functional space and individual traits. This way, fine-root axes (C3 and C4) and traits (SRL, D, N and RTD), and leaf economics spectrum axis (C2) and traits (ln, la, sla) can be compared after removing the dominant effect of size (C1) and size-related traits (ph, sm, ssd) on differences between groups of species. High values of explained variance mean that differences between the members of one group (e.g. differences between families) account for a large proportion of the total variance (in the total space, a specific plane, a specific component or a specific trait). a, Differences between families in the functional space considering different scales: four-dimensional space (total), aboveground plane (in green) and fine-roots plane (in red), the individual components of the trait space (C1 to C4), and the individual traits. b, Differences between biomes.
