From: The role of aspartic acid in reducing coral calcification under ocean acidification conditions

Figure 1

Skeletal amino acid concentrations of each coral genotype (G1, G2 and G3) cultured at 25 °C and over a range of seawater pCO2. Two replicate colonies of G3 were cultured at 400 and 750 µatm. Error bars indicate the mean standard deviation of analyses of duplicate drilled samples. Calcification rates20 (error bar shows typical standard deviation of 3–4 measurements per colony) and calcification site pH21 (adjusted to the pHNBS scale, error bars show 95% confidence limits) are shown for reference. Asx aspartic acid + asparagine, Glx glutamic acid + glutamine.
