Ocean acidification levels predicted for 2100 (seawater pH 7.8) did not significantly affect growth, arm regeneration, biochemical composition, or righting behavior of a sea star. (Laboratory study)

Sea urchins living in ocean acidification conditions for 45 days grew less. They were able to actively maintain the pH outside the cells in their bodies. (Laboratory study)

This study showed the effects of ocean acidification on ecosystems at coastal sites where volcanic CO2 vents lower the pH of the water. Along gradients of normal pH (8.1–8.2) to lowered pH (mean 7.8–7.9, minimum 7.4–7.5), typical rocky shore communities with abundant calcareous organisms shifted to communities lacking scleractinian corals ...

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 ocean acidification and warming on subtidal mussels and sea stars from Atlantic Canada

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 ...
