Appendix A. Analyses of temperature and grazer diversity effects on macroalgal biomass according to wave action.

Table A1. ANOVAs testing the effects of temperature and grazer diversity on the change in total macroalgal biomass, separately for (a) low and (b) enhanced wave action, including a priori planned contrasts for grazer presence and species richness. Significant effects are highlighted in bold.
