    Reduced pH sea water disrupts chemo-responsive behaviour in an intertidal crustacean

    Ocean acidification conditions interfered with the chemoreception, or “smelling”, that hermit crabs use to find shells and prey. The hermit crabs moved less, had lower flicking [...]

    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 [...]

    The effect of chronic and acute low pH on the intracellular DMSP production and epithelial cell morphology of red coralline algae

    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). [...]

    Effects of CO2-induced ocean acidification on physiological and mechanical properties of the starfish Asterias rubens

    The common sea star (Asterias rubens) appeared to withstand the effects of reduced seawater pH, at least for short-term exposures of 15 to 27 days, with no significant changes in the strength of [...]

    Evolutionary potential of marine phytoplankton under ocean acidification

    Marine phytoplankton have many characteristics, such as rapid cell division rates and large population sizes, that may enable them to adapt to ocean acidification and other types of global [...]

    Effects of increased CO2 on fish gill and plasma proteome

    Health of Atlantic halibut may be affected by moderate ocean acidification—by itself and combined with warmer temperatures.

    Multiple stressors of ocean ecosystems in the 21st century: Projections with CMIP5 models.

    This study used Earth system models to examine how four of the major stressors of ocean ecosystems—warming, acidification, deoxygenation, and changes in primary productivity—may evolve over the [...]

    Ocean acidification disrupts induced defences in the intertidal gastropod Littorina littorea

    Normally, common periwinkles produce thicker shells in the presence of crab predators. This study found that they did not do so when living in acidified seawater for 15 days. The snails [...]

    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 [...]

    Competition between calcifying and noncalcifying temperate marine macroalgae under elevated CO2 levels

    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 [...]
