Appendix H. Relationships between attributes of prey abundance, either the percent cover or recruitment of Megabalanus barnacles, and the density of predators, the whelk Hexaplex princeps, and the sea urchin Eucidaris galapagensis at different depths.

FIG. H1. Relationships between attributes of prey abundance, either the percent cover or recruitment of Megabalanus barnacles, and the density of predators, the whelk Hexaplex princeps (A, B), and the sea urchin Eucidaris galapagensis (C–F) at different depths. The density of these predators was unrelated to barncale cover and recruitment as determined by nonsignificant OLS and Model II regression.
