Appendix D. Correlation table showing Pearson’s r values relating the ten site and soil characteristics used for statistical analyses of group abundances. Correlations that are statistically significant (Dunn-Sidak P values < 0.05) are indicated in bold type, * and ** denote P values <0.01 and <0.001, respectively. MAT = mean annual temperature, SMD = soil moisture deficit, MMT = mean monthly temperature for the month of sample collection.
