Appendix 2—table 2. Dimension reduction of community-weighted mean trait values (CWMs) by varimax rotation principal component analysis (PCA).
Loadings and eigenvalues of rotation principal components (RC) selected from a varimax rotation PCA on the CWM of leaf traits (most influential variables in bold).
