Fig. 2From: Combined effects of ocean acidification and hypoxia on the early development of the thick shell mussel Mytilus coruscusThe effects of different pH (8.1, 7.7, 7.3) and DO concentrations (6 mg/L, 2 mg/L) on the fertilization rate at 2 h. Different lowercase letters represent significant differences between different pH under the same DO (P < 0.05)Back to article page
