The Arctic spider crab (Hyas araneus) appears to have a threshold of ocean acidification beyond which it fails to acclimate. In a 10-week experiment, it had a limited ability to adjust to effects of ocean acidification with and without also experiencing a warmer temperature. (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)

Coral Reefs Under Rapid Climate Change and Ocean Acidification

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.

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 ...

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)

Acidification and warming affect both a calcifying predator and prey, but not their interaction

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) ...

Impact of ocean acidification and elevated temperatures on early juveniles of the polar shelled pteropod Limacina helicina: Mortality, shell degradation, and shell growth.

When pre-winter juvenile pteropods were cultured at a range of warmer temperatures and ocean acidification levels for 29 days, temperature was the overriding cause of increased mortality. However, ocean acidification was the main factor in reducing shell diameter by 10-12 percent and increasing shell degradation by 41 percent. This study ...

Seasonal and species-specific response of five brown macroalgae to high atmospheric CO2

Four species of intertidal brown seaweeds increased their uptake of carbon dioxide (CO2) as ambient CO2 concentration increased, while one other species did not. The amount of increased CO2 uptake changed seasonally with temperature, and for one species the results indicated that future impacts of increased CO2 would be greatest ...
