Summary of correlation coefficients in the relationship between 15 plant functional traits and species abundance.

†: MH: Plant maximum height; LDMC-M: Leaf dry matter content of mature leaves; LDMC-F: Leaf dry matter content of current year's leaves; LA-M: Mean leaf area of mature leaves; LA-F: Mean leaf area of the current year's twigs; TLA: Total leaf area attached on the current year's twigs; SLA-M: Specific leaf area of mature leaves; SLA-F: Specific leaf area of current year's fresh leaves; Nmass-M: Nitrogen concentration of mature leaves; Nmass-F: Nitrogen concentration of current year's fresh leaves; Pmass-M: Phosphorus concentration of mature leaves; Pmass-F: Phosphorus concentration of current year's fresh leaves; TDMC: Twig dry matter content; TWD: Twig wood density; SWD: Stem wood density. ‡: The significantly correlated relationships at the landscape scale that were robust relative to the choice of null models at the plot scale are in bold; r is the Pearson product-moment correlation coefficient, and p is the significance level. NS means not significant.
