Figure 1 Functional strategies of tropical trees. (a) Trait loadings
biplot illustrating the leaf economics and stem economics spectra
as multiple factor dimension derived from the measurement of
16 functional traits. (b) Projection in multiple factor dimension of
the 4672 individuals for which traits were measured. Fabaceae
(green), Sapotaceae (red) and Burseraceae (blue) are highlighted as
examples of patterns in pantropical families. (c) Observed
correlation between leaf and stem trait groups (vertical line),
relative to the distribution expected if traits were randomly
assigned to groups.
