A coralline alga took up and used carbon and nutrients differently when living under ocean acidification conditions for 12 weeks, and the changes affected its ability to compete with other macroalgae (seaweed). (Laboratory study)

An investigation of the calcification response of the scleractinian coral Astrangia poculata to elevated pCO2 and the effects of nutrients, zooxanthellae, and gende

Corals collected in Woods Hole, Massachusetts, exhibited a complex set of responses when exposed to ocean acidification conditions, different nutrient levels, and two different temperatures. For example, female corals were more sensitive than males to elevated CO2 levels. Considering gender and spawning may be important when considering how populations of ...

Based on experiments with corals collected in Woods Hole, Massachusetts, this paper presents a conceptual model of how changes in nutrients and ocean acidification may interact to produce the range of effects that have been observed in different coral studies. (Laboratory study)

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)

Short-term acute hypercapnia affects cellular responses to trace metals in the hard clams Mercenaria mercenaria
