Biological effects of OCA

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 [...]

The amount of available phosphorus appeared to regulate how much inorganic carbon was used by a red alga grown at different levels of ocean acidification conditions. Growth reflected a balance [...]

The shells of eastern oysters from the Chesapeake Bay dissolved at faster rates when exposed to increasingly severe ocean acidification conditions. Oysters with fresh shells dissolved at the [...]

Thermal sensitivity of spider crabs, as indicated by heart rate, rose under increasing levels of ocean acidification conditions. The results suggest a narrowing of the spider crab’s thermal [...]

The combined effect of ocean acidification and rising temperature enhanced the sensitivity of a red alga to ultraviolet (UV) radiation. This was reflected in an increased damage rate, decreased [...]

Brittlestar arms regenerated faster in warmer water. However, they did not do so when the temperature increase was accompanied by ocean acidification conditions. This may have occurred because [...]

The egg production rate, hatching success, and respiration of a Mediterranean copepod were not affected by ocean acidification conditions. Warming and food availability did have some effects. [...]

Four species of copepods differed in their survival, egg production, and egg hatching success when exposed to ocean acidification conditions for 8 days. (Laboratory study)

Eelgrass was able to photosynthesize better under ocean acidification conditions because of increased availability of carbon dioxide. The results suggest that ocean acidification may [...]
