Appendix E. A table showing two separate mixed-effects ANOVAs for each clam species to examine the effects of site, predator exposure, and density on mortality (Anscombe transformed) and dry tissue growth.

Analyses for gonad growth are not presented here, but were qualitatively identical to those for dry tissue growth. The three way interaction between predator, density, and site could not be analyzed formally for Venerupis’ growth in this framework because all Venerupis were missing from the topless high density enclosures at the East Sound site.
