Notes. GC = control for greenhouse, G = greenhouse, FC = control for fertilization, LN = low-level nitrogen addition, HN = high-level nitrogen addition, HP = high-level phosphorus addition, HNHP = high-level nitrogen + high-level phosphorus addition, SFC = control for snow fence, SF = snow fence, EC = control for exclosure, and E = exclosure. Results are from post hoc tests following repeated measures one-factor (i.e., experimental treatment) ANOVA on the three data years (2005, 2011, and 2017). The upward arrows indicate a positive treatment effect whereas the downward arrows indicate a negative treatment effect and symbols following arrows indicate the significance levels: p .1 (no symbol), †p < .1, *p < .05, **p < .01. See Appendices S4, S7–S9 in the Supporting Information for specific statistical values.
