Changes in abundance (mean ± SE) of taxa (mean ± SE) with increasing pCO2 for the intertidal habitat. (a) Hard corals. (b) Coralline algae. (c) Fleshy algae. (d) Calcified fauna. A significant difference between pCO2 groups is indicated with a different letter (Kruskal-Wallis with Bonferroni-adjusted Fisher’s least significant difference).
