Mollusks

This study showed the effects of ocean acidification on ecosystems at coastal sites where volcanic CO2 vents lower the pH of the water. Along gradients of normal pH (8.1–8.2) to lowered pH (mean [...]

Blue mussels from the Kiel Fjord (Baltic Sea), where seawater pH tends to be low, were able to maintain growth rates when exposed to ocean acidification conditions (pH 7.7). in addition, juvenile [...]

Blue mussels grew and calcified 7 times faster in the Kiel Fjord (Baltic Sea), where low pH (ocean acidification) conditions prevailed, than at an outer fjord site where pH levels were higher In [...]

Common periwinkles consumed less food when living under ocean acidification conditions for five weeks, after having been exposed to those conditions for two weeks prior to the experiment. Their [...]

This article provides an overview of how rivers, which tend to be acidic compared to the ocean, affect shellfish, with a focus on the Gulf of Maine.

King scallops in Norway clapped their shells (an escape response) with less force after being exposed to ocean acidification conditions for at least 30 days. The number of claps was unchanged, [...]

Ocean acidification conditions suppressed the metabolism of an Antarctic pteropod by approximately 20 percent in some instances. However, the effect on metabolism depended on abundance [...]

Muscle length and claw strength of green crabs decreased after the crabs had been in ocean acidification conditions (pH 7.7) for 5 months. Periwinkles tended to have weaker shells in response to [...]

Estuarine waters are more susceptible to acidification because they are subject to multiple acid sources and are less buffered than marine waters. Consequently, estuarine shell-forming species [...]

The shell calcification rates of small hard clams in five size classes (0.39, 0.56, 0.78, 0.98, and 2.90 mm shell height) decreased with increasingly severe ocean acidification conditions [...]
