Diurnal pCO2 fluctuations have the potential to modulate the biological impact of ocean acidification (OA) on reef calcifiers, yet little is known about the physiological and biochemical responses of scleractinian corals to fluctuating carbonate chemistry under OA. Here, we exposed newly settled Pocillopora damicornis for 7 days to ambient pCO2, steady and elevated pCO2 (stable OA) and diurnally fluctuating pCO2 under future OA scenario (fluctuating OA). We measured the photo-physiology, growth…

Ocean acidification alters the thermal performance curves of brooded larvae from the reef coral Pocillopora damicornis
Establishing the thermal reaction norm of coral larvae under elevated pCO2 is crucial to anticipate how larval dispersal and population maintenance may be affected by future climate change. Here, we
Impacts of elevated temperature and pCO2 on the brooded larvae of Pocillopora damicornis from Luhuitou Reef, China: evidence for local acclimatization
The results suggest that brooded larvae of P. damicornis larvae from Luhuitou may be preadapted to cope with projected warming and ocean acidification, and it appears that corals from highly variable environments may have increased resilience to the widespread climate change.
Plasticity of symbiont acquisition in new recruits of the massive coral Platygyra daedalea under ocean warming and acidification
It is suggested that ocean warming is likely to be more deleterious for the early success of P. daedalea than ocean acidification and insights into the understanding of coral-algal symbiotic partnerships under future climatic conditions are provided.
New Insights From Transcriptomic Data Reveal Differential Effects of CO2 Acidification Stress on Photosynthesis of an Endosymbiotic Dinoflagellate in hospite
The transcriptomic response of the endosymbiont Symbiodinium microadriaticum in the Red Sea coral Stylophora pistillata subjected to different long-term OA treatments is investigated, suggesting that over-expression of photosynthesis-related genes is not a beneficial effect of OA but rather an acclimation responded of the holobiont to different water chemistries.
Effects of Nitrate Enrichment on Respiration, Photosynthesis, and Fatty Acid Composition of Reef Coral Pocillopora damicornis Larvae
In the foreseeable future, coastal coral reef ecosystems are likely to face further increases in eutrophication. Lipids and fatty acids (FAs), as important components of corals, are becoming a hot
Diel pCO2 variation among coral reefs and microhabitats at Lizard Island, Great Barrier Reef
Most laboratory experiments examining the effect of ocean acidification on marine organisms use stable pH/pCO2 treatments based on average projections for the open ocean. However, pH/pCO2 levels vary
Paradise lost: End‐of‐century warming and acidification under business‐as‐usual emissions have severe consequences for symbiotic corals
The results indicate that ocean warming and acidification under business-as-usual CO2 emission scenarios will likely extirpate thermally-sensitive coral species before the end of the century, while slowing the recovery of more thermologically-tolerant species from increasingly severe mass coral bleaching and mortality.
Ocean Futures for the World’s Largest Yellowfin Tuna Population Under the Combined Effects of Ocean Warming and Acidification
The impacts of climate change are expected to have profound effects on the fisheries of the Pacific Ocean, including its tuna fisheries, the largest globally. This study examined the combined effects


Acclimatization of the Crustose Coralline Alga Porolithon onkodes to Variable pCO2
The significance of the original habitat for the coralline calcification response to variable, high p CO2 indicates that individuals existing in dynamic pCO2 habitats may be acclimatized to OA within the scope of in situ variability.
Diurnal fluctuations in seawater pH influence the response of a calcifying macroalga to ocean acidification
Investigation of mimicry of biologically mediated diurnal shifts in pH—based for the first time on pH time-series measurements within a kelp forest—would offset or amplify the negative effects of OA on calcifiers, finding growth rates were lower and fluctuations in pH acted additively to further reduce growth.
Effects of diurnally oscillating pCO2 on the calcification and survival of coral recruits
It is hypothesized that the mechanism underlying this response of coral recruits to diurnally oscillating pCO2 is highly p CO2-mediated, night-time storage of dissolved inorganic carbon that fuels daytime calcification.
Effect of Ocean Acidification and pH Fluctuations on the Growth and Development of Coralline Algal Recruits, and an Associated Benthic Algal Assemblage
The growth and development of the juvenile coralline alga Arthrocardia corymbosa is followed, using a novel OA laboratory culture system to simulate the pH fluctuations observed within a kelp forest and finding that pH-sensitive species may survive lower pH in the presence of diatoms and fleshy macroalgae, whose high metabolic activity may raise the pH of the local microhabitat.
Increased temperature mitigates the effects of ocean acidification on the calcification of juvenile Pocillopora damicornis, but at a cost
AbstractThis study tested the interactive effects of increased seawater temperature and CO2 partial pressure (pCO2) on the photochemistry, bleaching, and early growth of the reef coral Pocillopora
Similar controls on calcification under ocean acidification across unrelated coral reef taxa
The capacity of organisms from taxa with vastly different calcification mechanisms to regulate their internal chemistry under extreme chemical conditions is demonstrated, providing an explanation for the resistance of some species to OA, and demonstrating how changes in seawater DIC and pH under OA influence calcification of key coral reef taxa.
Major Cellular and Physiological Impacts of Ocean Acidification on a Reef Building Coral
Changes in pH and ocean chemistry consistent with two scenarios put forward by the Intergovernmental Panel on Climate Change drive major changes in gene expression, respiration, photosynthesis and symbiosis of the coral, Acropora millepora, before affects on biomineralisation are apparent at the phenotype level.
Diel pCO2 oscillations modulate the response of the coral Acropora hyacinthus to ocean acidification
Increased calcification in the 400 to 2000 µatm oscillatory pCO2 treatment suggests that natural diel oscillations in pCO3 could play a role by reducing the locally negative effects of rising pCO1 associated with ocean acidification on coral calcification.
Calcification responses to diurnal variation in seawater carbonate chemistry by the coral Acropora formosa
Significant diurnal variation in seawater carbonate chemistry occurs naturally in many coral reef environments, yet little is known of its effect on coral calcification. Laboratory studies on the
