Best models identified by stepwise multiple regression using Principal Components (Prin) 1 through 4 as predictors for the multifunctional resistance and resilience of C and N cycling functions. Resistance and Resilience indices were calculated for drought (DRT) and drought+heat (D + H) stressed soils with reference to an unstressed control. P-values are given for every parameter entered into the model and not removed (threshold p < 0.15), and for the model as a whole. Signs in parentheses after parameter names represent parameter directionality.
