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.

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)
