Appendix A. Five tables showing the ANOVA results of Nucella present on barncales or mussels, and of the number of barnacles and mussels consumed, the amount of energy acquired by Nucella, the amount of tissue produced by Nucella, and the growth efficiency of Nucella, all in the presence and absence of predation risk and different levels of snail removal.
