“…The reaction requires continuous elimination and buffering of protons to maintain pH within a range that favors CaCO 3 deposition [48]. Using a similar shell damage index to grade shells, Bressan et al [20] reported significant shell damage in juvenile Mytilus galloprovincialis and Chamelea gallina following chronic exposure to elevated CO 2 . The thin, outer periostracum, made of sclerotized fibrous protein, protects and provides a scaffold for mineralization of the underlying layers [53].…”

“…Anecdotally, we noted shells of mussels exposed to !162 mg/L CO 2 cracked easily and had holes that extended through the shell. Using a similar shell damage index to grade shells, Bressan et al [20] reported significant shell damage in juvenile Mytilus galloprovincialis and Chamelea gallina following chronic exposure to elevated CO 2 . Beniash et al [18] reported 40% reduction in shell dry mass and reduced microhardness and fracture resistance of juvenile oyster Crassostrea virginica exposed to PCO 2 3500 matm.…”

Carbon dioxide (CO ) has shown promise as a tool to control movements of invasive Asian carp, but its effects on native freshwater biota have not been well studied. The authors evaluated lethal and sublethal responses of juvenile fatmucket (Lampsilis siliquoidea) mussels to CO at levels (43-269 mg/L, mean concentration) that bracket concentrations effective for deterring carp movement. The 28-d lethal concentration to 50% of the mussels was 87.0 mg/L (95% confidence interval [CI] 78.4-95.9) and at 16-d postexposure, 76.0 mg/L (95% CI 62.9-90.3). A proportional hazards regression model predicted that juveniles could not survive CO concentrations >160 mg/L for more than 2 wk or >100 mg/L CO for more than 30 d. Mean shell growth was significantly lower for mussels that survived CO treatments. Growth during the postexposure period did not differ among treatments, indicating recovery of the mussels. Also, CO caused shell pitting and erosion. Behavioral effects of CO included movement of mussels to the substrate surface and narcotization at the highest concentrations. Mussels in the 110 mg/L mean CO treatment had the most movements in the first 3 d of exposure. If CO is infused continuously as a fish deterrent, concentrations <76 mg/L are recommended to prevent juvenile mussel mortality and shell damage. Mussels may survive and recover from brief exposure to higher concentrations. Environ Toxicol Chem 2017;36:671-681. Published 2016 Wiley Periodicals Inc. on behalf of SETAC.

“…Recent studies continue to find reduced calcification, reduced rates of repair calcification and weakened calcified structures under acidified conditions (Bressan et al, 2014;Coleman et al, 2014;Fitzer et al, 2014;Pörtner et al, 2014;Wei et al, 2015). Some species have been observed to increase calcification rates at pCO 2 ranging from 600 to 900 µatm, before a decrease at higher pCO 2 (Collard et al, 2014;Dery et al, 2014;Langer et al, 2014).…”

The 5th Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) states with very high certainty that anthropogenic emissions have caused measurable changes in the physical ocean environment. These changes are summarized with special focus on those that are predicted to have the strongest, most direct effects on ocean biological processes; namely, ocean warming and associated phenomena (including stratification and sea level rise) as well as deoxygenation and ocean acidification. The biological effects of these changes are then discussed for microbes (including phytoplankton), plants, animals, warm and cold-water corals, and ecosystems. The IPCC AR5 highlighted several areas related to both the physical and biological processes that required further research. As a rapidly developing field, there have been many pertinent studies published since the cut off dates for the AR5, which have increased our understanding of the processes at work. This study undertook an extensive review of recently published literature to update the findings of the AR5 and provide a synthesized review on the main issues facing future oceans. The level of detail provided in the AR5 and subsequent work provided a basis for constructing projections of the state of ocean ecosystems in 2100 under two the Representative Concentration Pathways RCP4.5 and 8.5. Finally the review highlights notable additions, clarifications and points of departure from AR5 provided by subsequent studies.

“…squamosa survival and growth since the addition of elevated CO 2 resulted in mortality and reduced growth. Negative growth at elevated CO 2 in live weight and shell length of the venus clam has also been observed, although at quite high p CO 2 (~2650 μatm) and low pH (7.38) seawater that was undersaturated with respect to aragonite [51]. In such undersaturated conditions, shell dissolution is likely to contribute to decreases in shell length.…”

Giant Clams and Rising CO2: Light May Ameliorate Effects of Ocean Acidification on a Solar-Powered Animal

Global climate change and ocean acidification pose a serious threat to marine life. Marine invertebrates are particularly susceptible to ocean acidification, especially highly calcareous taxa such as molluscs, echinoderms and corals. The largest of all bivalve molluscs, giant clams, are already threatened by a variety of local pressures, including overharvesting, and are in decline worldwide. Several giant clam species are listed as ‘Vulnerable’ on the IUCN Red List of Threatened Species and now climate change and ocean acidification pose an additional threat to their conservation. Unlike most other molluscs, giant clams are ‘solar-powered’ animals containing photosynthetic algal symbionts suggesting that light could influence the effects of ocean acidification on these vulnerable animals. In this study, juvenile fluted giant clams Tridacna squamosa were exposed to three levels of carbon dioxide (CO2) (control ~400, mid ~650 and high ~950 μatm) and light (photosynthetically active radiation 35, 65 and 304 μmol photons m-2 s-1). Elevated CO2 projected for the end of this century (~650 and ~950 μatm) reduced giant clam survival and growth at mid-light levels. However, effects of CO2 on survival were absent at high-light, with 100% survival across all CO2 levels. Effects of CO2 on growth of surviving clams were lessened, but not removed, at high-light levels. Shell growth and total animal mass gain were still reduced at high-CO2. This study demonstrates the potential for light to alleviate effects of ocean acidification on survival and growth in a threatened calcareous marine invertebrate. Managing water quality (e.g. turbidity and sedimentation) in coastal areas to maintain water clarity may help ameliorate some negative effects of ocean acidification on giant clams and potentially other solar-powered calcifiers, such as hard corals.
