Spider crabs were not able to fully buffer their internal pH when exposed to ocean acidification conditions for 12 days. Behavior of the crabs was not impaired by ocean acidification conditions or acute heat stress when they happened separately, but it was when both occurred at the same time. (Laboratory ...

Future oceanic warming and acidification alter immune response and disease status in a commercial shellfish species, Mytilus edulis L.

Ocean acidification and/or warmer temperatures may affect immune response, parasite abundance and diversity, and bacterial infection of blue mussels. (Laboratory study)

Ocean warming, more than acidification, reduces shell strength in a commercial shellfish species during food limitation

After six months exposure, warmer temperatures, but not ocean acidification, significantly reduced the shell strength of blue mussels, which were fed for a limited period of only 4-6 hours per day. The rising temperatures seemed to affect shell strength indirectly, as the mussels apparently re-allocated energy from shell formation to ...

Interactive effects of elevated temperature and CO2 levels on metabolism and oxidative stress in two common marine bivalves (Crassostrea virginica and Mercenaria mercenaria)

Hard shell clams and eastern oysters exposed to moderate warming and ocean acidification conditions showed no sign of persistent oxidative stress. This indicates that long-term exposure to moderately elevated CO2 and temperature minimally affects the cellular redox status in these bivalve species and that the earlier observed negative physiological effects ...

Effects of ocean acidification and elevated temperature on shell plasticity and its energetic basis in an intertidal gastropod.

Common periwinkles had lower shell growth rates and less increase in shell thickness when grown in ocean acidification conditions, warmer temperatures, or both. Shells were also less pointed and more rounded. Those changes in shell growth appeared to result from disruption of the periwinkle's metabolism. (Laboratory studied)

Food supply and seawater pCO2 impact calcification and internal shell dissolution in the blue mussel Mytilus edulis

Blue mussels from the Baltic Sea grew less when raised for seven weeks under ocean acidification conditions and with limited food algae. Corrosion of the internal shell surface occurred at a range of ocean acidification levels when food supply was low. When food supply was high, corrosion occurred only in ...

Proteomic response of marine invertebrate larvae to ocean acidification and hypoxia during metamorphosis and calcification

This study investigated the response of metamorphosing larvae of a tubeworm species (Hydroides elegans) to two climate change stressors—ocean acidification (pH 7.6) and low oxygen (hypoxia)—and to both combined. (Laboratory study)
