Effects of seawater acidification in light (open symbols) and darkness (closed symbols) on calcification (a–c) net photosynthetic rate (d–f) and respiration rate (g–i) in Stylophora pistillata (a–g), Pocillopora damicornis (b–h) and Acropora hyacinthus (c–i). Data are means ± standard deviation. See Table 2 and Supplementary 2 for statistical analysis and Table 1 for carbonate chemistry corresponding to each seawater pH.
