Appendix A (TABLE A1). Results from the PCA of the functional trait data. The PCA axis loadings and percent variance explained by each axis for the first three axes are presented. Significant loadings are displayed using bold font. The location of species in the three dimensional PCA space was used to construct the functional dendrogram used in the study.
