Figure 3. Effects of ocean acidification on fertilization success (FSR) in H. erythrogramma.
(A) Mean (±S.E.) observed (FSRobs) and modelled fertilization success (FSRmod) for pHs 7.6 and 7.8, and mean (±S.E.) FSR50 (50% of maximum FSR) for pH 8.1. (B) Bootstrapped mean logarithmic response ratios (±95% CI) of effects of ocean acidification on FSRobs and FSRmod. FSRmod shows change in fertilization success expected due to ocean acidification’s influence on sperm swimming behaviour (Fig. 2C). (n = 18 replicate trials). See text for details.
