Sea stars collected in Nova Scotia, Canada, grew more slowly under ocean acidification conditions, and their growth rate decreased further with a warmer temperature. In contrast, blue mussel grew more quickly with no response to temperature within the tested range. Predation of sea stars on mussels, measured as per-capita consumption ...
When exposed to ocean acidification conditions (pH 7.7) for 80 days, coralline algae survived by increasing their calcification rates. However, those algae for which the pH had been dropped rapidly, rather than slowly and gradually, exhibited weaknesses in their calcite skeletons. (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)
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)
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)
Weekly growth rate of a cold-water seaweed (Porphyra linearis) averaged 53% in regular air and 28% in CO2-enriched air. (Laboratory study)
Experiments with blue mussels from the Baltic Sea revealed a molecular basis of observed changes in physiology in response to ocean acidification. (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)
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)
Blue mussels and ocean quahogs from the Baltic Sea appeared to tolerate wide ranges of seawater temperature and ocean acidification over a period of 13 weeks. (Laboratory study)
