Appendix A. Nested ANOVAs for effects of lace bug or aphid exclusion on leaf chemistry.
TABLE A1. Nested ANOVAs for effects of lace bug or aphid exclusion on leaf chemistry. Separate analyses were conducted for leaves collected when exclusion began (June), at mid-season (August), and after leaf senescence (October). Phenolics were not measured in June samples.
