Figure 2. Performance of Argopecten irradians larvae grown under three levels of CO₂, approximately 250, 390, and 750 ppm, and two temperatures 24°C (white bars) and 28°C (black bars; see Table 1 for carbonate chemistry).

a. Percent metamorphosed of individuals 18 days post- fertilization, b. Percent larval survival (20 days post-fertilization), c. Diameters of larvae (20 days post-fertilization), and d. Lipid index (lipid area/total area) (20 days post-fertilization). Error bars represent standard deviation of replicated vessels per treatment (n = 4 per treatment), and for Tukey multiple comparisons, p≤0.05. Statistical results were based on arcsine square root transformations of the % data for a. and b.
