Appendix C. A table reporting the results from multiple regression analyses between surface soil moisture and climatic variables.

TABLE C1. Results from multiple regression analyses to predict surface soil moisture (0–4 cm) within sites (1–4) and patches (P, IP). IV = independent variable; PPT = precipitation in the previous month, and T = mean monthly temperature. With the exception of 3P and 4P, soil moisture data were log transformed for analyses.
