Kristin M. Aquilino and John J. Stachowicz. 2012. Seaweed richness and herbivory increase rate of community recovery from disturbance. Ecology 93:879–890.

Appendix B. A figure showing percent cover of perennial algae, Shannon diversity, and density of perennial algae by algal species treatment, and a table of the estimated slopes and standard errors of percent cover of perennial algal species during the recovery period in the presence and absence of herbivores.

Fig. B1. Mean ± standard error of the (a) percent cover of perennial algae, (b) Shannon diversity, and (c) density of perennial algae by algal species treatment, averaged across both herbivore treatments.

Table B1. Estimated slope and standard error of percent cover of perennial algal species during the recovery period (0–18 months) in the presence and absence of herbivores. P values compare the difference in slope between the polyculture and each monoculture.
