Kylla M. Benes and Robert C. Carpenter. 2015. Kelp canopy facilitates understory algal assemblage via competitive release during early stages of secondary succession. Ecology 96:241–251. http://dx.doi.org/10.1890/14-0076.1
Appendix B. ANOVA of observational data on the distribution and abundance of macroalgal groups.
Table B1. The effects of canopy, season, and year on the percent cover of foliose red algae, brown algae, articulated coralline algae and crustose coralline algae. Data were arcsine transformed and then analyzed using a three-way, mixed model ANOVA in which canopy and season were treated as fixed factors and year as a random factor. Significant P values are shown in bold.
