Kylla M. Benes and Robert C. Carpenter. 2015. Kelp canopy facilitates understory algal assemblage via competitive release during early stages of secondary succession. Ecology 96:241251. http://dx.doi.org/10.1890/14-0076.1

Appendix C. ANOVA of settlement for each macroalgal group.

Table C1. Effects of canopy, season and sampling period within each season on the settlement of foliose red algae, brown algae, articulated coralline algae and crustose coralline algae. Data were transformed to log (x + 1) and then analyzed using a partially nested ANOVA. Significant P values are shown in bold.
