| 9 | Nmass, Narea, LAI | 70.71 | 86.28 |
| 10 | Narea, LMA, LAI | 70.80 | 86.17 |
| 11 | Nmass, Narea, LMA, LAI | 68.48 | 85.85 |
The traits are Nmass (mass-based leaf nitrogen), Narea (area-based leaf nitrogen), LMA (leaf mass per area) and LAI (leaf area index). Nmass, Narea and LMA were log10-transformed before analysis.
