Appendix E. Multiple linear regression analysis results for functional diversity metrics.

Table E1. Multiple linear regression analyses on functional diversity metrics. MAT; MAP: mean annual temperature or precipitation for the 10 years preceding vegetation surveys (1944–1953 and 1996–2005). Soil PCA1 is associated with higher soil fertility; soil data were collected in the modern sampling period. Forested area is the proportion of forested land within 2 km of the site; data are from 1990.
