Appendix C. A figure of the nonmetric multidimensional scaling (NMDS) analysis of environmental variables.
FIG. C1. Biplot of the first two axes for the nonmetric multidimensional scaling (NMDS) analysis of microclimate, soil nutrient, and soil moisture variables in different microhabitats. The NMDS is based on a Euclidean distance dissimilarity matrix of normalized environmental variables, and has a Kruskal’s stress of 0.07. Confidence ellipses (Gaussian bivariate) are analogous to 1 SD. |
