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)
Under conditions expected in the 21st century, global warming and ocean acidification will cause corals to become increasingly rare on reef systems. This review presents future scenarios for coral reefs that predict increasingly serious consequences for reef-associated fisheries, tourism, coastal protection, and people.
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)
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)
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)
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 ...
Carbon dioxide partial pressure and vitamin B12 interactively influenced growth, carbon fixation, trace metal requirements, and trace metal net use efficiencies of the subarctic diatom Attheya sp. (Laboratory study)
Muscle length and claw strength of green crabs decreased after the crabs had been in ocean acidification conditions (pH 7.7) for 5 months. Periwinkles tended to have weaker shells in response to acidification. Predation by green crabs on periwinkles did not appear to change under ocean acidification conditions. (Laboratory study) ...
