Impact of ocean acidification on the physiology of digestive gland of razor clams Sinonovacula constricta
Ocean acidification (OA) can have widespread implications for marine bivalves. While our current understanding of OA effects on the physiological performance is increasing, very little is known about the physiology of digestive gland of marine bivalves in response to OA. Here, we examined how the di...
