  1. Traits are ordered in proportion to variance explained. N leaf Nitrogen concentration, C:N ratio of leaf carbon to leaf nitrogen, SLA specific leaf area, SM seed mass, P leaf phosphorus concentration, AA aluminium accumulation, Nfix atmospheric N-fixation, Her hermaphroditism, FF fleshy fruit, WD wood density, C leaf carbon concentration, Nectar nectar producing, EM ectomycorrhiza. For units see Supplementary Box 1. R2 proportion of variance explained by trait; p significance level. Type: the spectrum or process the trait is important to: LES leaf economic spectrum, SR stature recruitment trade-off, R roots, mycorrhiza, N-fixing and Al-accumulation, BR breeding system, DIS trait important for dispersal.
