Sea urchins living in ocean acidification conditions for 45 days grew less. They were able to actively maintain the pH outside the cells in their bodies. (Laboratory study)

Two species of brown kelp responded differently to being grown for 55 days under ocean acidification conditions. One grew more, and the other grew less. There were negative indirect effects on black turban snails that fed on the kelp. (Laboratory study)

Ocean acidification conditions and warmer temperatures reduced the survival, development, growth, and lipid synthesis of hard clam and bay scallop larvae. During the juvenile life stages, ocean acidification negatively affected juvenile eastern oysters and bay scallops, but not hard clams. Larvae were substantially more vulnerable to ocean acidication than juveniles ...

Exposure of early life stages of a common estuarine fish (inland silverside) to ocean acidification conditions expected in the world’s oceans later this century reduced survival by 74 percent and growth by 18 percent. The egg stage was significantly more vulnerable than the post-hatch larval stage. These findings challenge the ...

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 mussels in the fjord settle mostly in summer when pH is lowest. The findings suggest that mussels may ...

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 addition, the mussels were able to outcompete barnacles at the inner fjord, low pH site. Thus, blue ...
