Anthropogenic CO2 is a major driver of current environmental change in most ecosystems1, and the related ocean acidification (OA) is threatening marine biota2. With increasing pCO2, calcification rates of several species decrease3, although cases of up-regulation are observed4. Here, we show that biological control over mineralization relates to species abundance along a natural pH gradient. As pCO2 increased, the mineralogy of a scleractinian coral (Balanophyllia europaea) and a mollusc… 
Calcifying Response and Recovery Potential of the Brown Alga Padina pavonica under Ocean Acidification
Results showed that this calcifying alga did survive under acute environmental pHTS changes but its calcification was significantly reduced.
Photosynthesis and mineralogy of Jania rubens at low pH/high pCO2: A future perspective.
Ocean warming and acidification synergistically increase coral mortality
A synergistic adverse effect on mortality rates is shown, for solitary and colonial, symbiotic and asymbiotic corals, suggesting that high seawater temperatures may have increased their metabolic rates which, in conjunction with decreasing pH, could have led to rapid deterioration of cellular processes and performance.
Ocean acidification causes variable trait‐shifts in a coral species
It is demonstrated how coral populations can persist in high pCO2 environments, making this system a powerful candidate for investigating acclimatization and local adaptation of organisms to global environmental change.
CO2 leakage alters biogeochemical and ecological functions of submarine sands
It is found that community compositions and important ecological functions are permanently altered under high CO2, most notably in the composition of heterotrophs and microbial sulfate reduction rates.
Reproduction of an azooxanthellate coral is unaffected by ocean acidification
It is suggested that reproductive potential may be quite tolerant to decreasing pH, with implications for ecosystem function and services in a changing ocean.
Inorganic carbon physiology underpins macroalgal responses to elevated CO2
Predicting the responses of macroalgal species to ocean acidification is complex, but it is demonstrated that the response of assemblages to elevated CO2 are correlated with inorganic carbon physiology.
Gains and losses of coral skeletal porosity changes with ocean acidification acclimation
It is shown that in response to reduced skeletal mineralization at lower pH, corals increase their skeletal macroporosity ( features >10 μm) in order to maintain constant linear extension rate, an important criterion for reproductive output.
Structural and Functional Analyses of Motile Fauna Associated with Cystoseira brachycarpa along a Gradient of Ocean Acidification in a CO2-Vent System off Panarea (Aeolian Islands, Italy)
Ocean acidification (OA), one of the main climate-change-related stressors linked to increasing CO2 concentration in the atmosphere, is considered an important threat to marine biodiversity and
Life-Long Coral Skeletal Acclimatization at CO2 Vents in Papua New Guinea Reveals Species- and Environment-Specific Effects
The fact that the skeletal parameters varied only at one of the two seep sites suggests that other local environmental conditions interact with OA to modify the coral skeletal parameters.


Marine calcifiers exhibit mixed responses to CO2-induced ocean acidification
The results suggest that the impact of elevated atmospheric p CO2 on marine calcification is more varied than previously thought.
Competition between calcifying and noncalcifying temperate marine macroalgae under elevated CO2 levels
The results suggest that CO2 will alter the competitive strengths of calcifying and noncalcifying temperate benthic macroalgae, resulting in different community structures, unless these species are able to adapt at a rate similar to or faster than the current rate of increasing sea-surface CO2 concentrations.
Temperate and tropical brown macroalgae thrive, despite decalcification, along natural CO2 gradients.
This is the first study to provide a comparison of ecological changes along CO2 gradients between temperate and tropical rocky shores and the similarities found in the responses of Padina spp.
Effects of ocean acidification on invertebrate settlement at volcanic CO2 vents
It is shown that increased levels of CO2 can profoundly affect the settlement of a wide range of benthic organisms and small crustaceans was able to settle and survive under these conditions.
Modeling of pH change due to carbon assimilation indicated that macroalgal species that could utilize HCO3− increased their use of CO2 in the pH 7.5 treatments compared to pH7.9 treatments, and so H CO3−‐‐using macroalgae may benefit in future seawater with elevated CO2.
Response of Halimeda to ocean acidification: field and laboratory evidence
Halimeda crystal data from apical sections indicate that increases in crystal concentration and decreases in crystal width occurred over the last 40+ years, indicating that the effect of increased p CO 2 and decreased pH on calcification is reflected in the crystal morphology of this organism.
Losers and winners in coral reefs acclimatized to elevated carbon dioxide concentrations
Experiments have shown that ocean acidification due to rising atmospheric carbon dioxide concentrations has deleterious effects on the performance of many marine organisms(1-4). However, few
