In green sea urchins from the Baltic Sea, the spines appear to be vulnerable to ocean acidification, which might reduce the urchins' protection against predators. Intestinal epithelia may play a role in mediating acid-base balance in the urchin. (Laboratory study)

Ocean acidification increased the negative effects of cadmium pollution on the immune systems of quahogs and eastern oysters, potentially making them more vulnerable to pathogens and disease. (Laboratory study)

Interactive effects of elevated temperature and CO2 levels on energy metabolism and biomineralization of marine bivalves Crassostrea virginica and Mercenaria mercenaria.

When quahogs and eastern oysters were exposed to a combination of warmer temperatures and ocean acidification for 15 weeks, shell hardness decreased in both species. By itself, ocean acidification had a small effect on the physiology and metabolism of both species, but it improved survival in oysters. (Laboratory study)

Experiments with quahogs exposed to trace metal pollutants under ocean acidification conditions revealed complex interactions and indicated that variations in environmental CO2 may modulate the biological effects of trace metals. (Laboratory study)

Effect of elevated pCO2 on the production of dimethylsulphonioproprionate (DMSP) and dimethylsulphide (DMS) in two species of Ulva (Chlorophyceae)

Intracellular concentration of DMSP remained unaffected in two macroalgae species (Ulva lactuca and U. clathrata) under ocean acidification conditions, but significant differences in extracellular production of DMSP and DMS occurred in U. lactuca. (Laboratory study)

Effects of high CO2 seawater on the copepod (Acartia tsuensis) through all life stages and subsequent generations.

Ocean acidification conditions did not affect survival, body size, or developmental speed of a copepod species during any of its life stages. Egg production and hatching rates also did not change among generations of females exposed to ocean acidification conditions. Thus, this copepod appears more tolerant to ocean acidification than ...
