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 ...

Growth and photosynthetic efficiency of a coralline alga decreased under high CO2 levels. These changes could affect the alga's ability to compete with other macroalgae (seaweeds). (Laboratory study)
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)
A species of phytoplankton changed how it used carbon and energy when it was exposed to higher CO2 levels. The effects differed depending on whether the CO2 level change happened over 15-16 generations versus 33-57 generations. (Laboratory study)
When the Gulf toadfish was exposed to levels of ocean acidification that are projected to occur by 2300, it lost greater amounts of bicarbonate ions through its intestine. (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)
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.
When grown under ocean acidification conditions, a non-calcifying seaweed (Chondrus crispus) grew to cover more area, while a calcifying alga (Corallina officinalis) decreased in the area it covered. (Laboratory experiment)
The calcium carbonate skeleton of a coralline red alga was estimated to become highly vulnerable to dissolving at an aragonite saturation state between 1.1 and 0.9, which is projected to occur in some parts of the Arctic between 2030 and 2050 if carbon emissions follow "business as usual" scenarios. (Laboratory ...
The release of dimethylsulphoniopropionate (DMSP) by marine algae has major impacts on the global sulphur cycle and may influence local climate through the formation of dimethylsulphide (DMS). However, the effect of global change on DMSP/DMS (DMS(P)) production by algae is not well understood. This study examined the effect of low pH ...
