Two-way analyses of variance for the effects of sampling date and site on % cover of corals, brown seaweed Lobophora variegata, algal turfs and crustose calcareous algae (CCA).

Data were Arc-sin transformed. Interactions between date and site were significant; therefore, data were analysed for site effects within dates and date effects within sites, using a one-way ANOVAs and Tukey's post-hoc comparisons (results not shown).
