• Effects of chronic low carbonate saturation levels on the distribution, growth and skeletal chemistry of deep-sea corals and other seamount megabenthos (2011, background): “As recently highlighted by Cohen & Holcomb (2009), one or more cell membranes (the scleractinian calicoblastic layer and isidid coenenchyme) envelope the skeleton of live corals when the latter are fully expanded.”
• The reef coral two compartment proton flux model: A new approach relating tissue-level physiological processes to gross corallum morphology (2011, background): “Calcification occurs in the space between the calicodermis and the skeleton through a presumed proton transfer process that increases the pH of the fluid to a point where CaCO3 will crystallize out as aragonite (Allemand et al., 2004; Cohen and Holcomb, 2009; Cohen and McConnaughey, 2003).”
• Short-term metabolic and growth responses of the cold-water coral lophelia pertusa to ocean acidification (2013, background): “Scleractinian responses to ocean acidification may also not be observable in physiology, and may be enacted through changes in biomineralisation (Cohen and Holcomb, 2009; Holcomb et al., 2010).”
• The metabolic response of pteropods to acidification reflects natural CO 2 -exposure in oxygen minimum zones (2011, unknown): “Ocean acidification is also of particular concern for shell bearing organisms since calcification requires additional energy in the face of decreased carbonate ion concentration in seawater (Cohen and Holcomb, 2009).”
• A nonlinear calcification response to CO2-induced ocean acidification by the coral Oculina arbuscula (2010, background): “Although actual data on the composition of the calcifying medium is limited and deduced largely from proxy measurements of crystal chemistry and morphology (e.g., Gaetani and Cohen 2006; Cohen et al. 2009; Cohen and Holcomb 2009), there is one set of in situ microelectrode data, reportedly from the ”
• Resiliency of juvenile walleye pollock to projected levels of ocean acidification (2012, background): “While it is notable that we did not see negative effects of elevated CO2 on somatic growth rates of walleye pollock, measurement of growth rates does not provide a complete picture of potential energetic effects of ocean acidification (Cohen & Holcomb 2009, Nowicki et al. 2012).”
• Ocean acidification impacts multiple early life history processes of the Caribbean coral Porites astreoides (2011, background): “Re- cent work suggests that the nutritional status of a coral may play a role in its sensitivity to acidified conditions, with decreased sensitivity in individuals with supple- mental food and/or nutrients (Cohen & Holcomb, 2009).”
• A developmental and energetic basis linking larval oyster shell formation to acidification sensitivity (2013, background): “Assuming a calcium-ATP linked proton pump [Cohen and Holcomb, 2009] (2molH+= 1mol ATP), 1mol CaCO3=1molH +, and using an estimated available energy from converting ATP to ADP of 30 KJ mol 1, the estimated cost of precipitating ~160 ng of CaCO3 is ~24mJ.”
• Mangrove and Seagrass Beds Provide Different Biogeochemical Services for Corals Threatened by Climate Change (2016, background): “550 Increased heterotrophy (Cohen and Holcomb, 2009) and the addition of nutrients 551 (Langdon and Atkinson, 2005) have also been suggested to enhance calcification for some coral 552 species (Cohen and Holcomb, 2009).”
• Species-specific consequences of ocean acidification for the calcareous tropical green algae Halimeda (2011, background): “Most organisms that precipitate calcium carbonate do so intracellularly, where the saturation state is highly regulated via ion pumping such as in articulated CRAs (Borowitzka 1979, Lee & Carpenter 2001), corals (Cohen & Holcomb 2009), sea urchins (Wilt 2002), and bivalves (Marin et al. 1996).”
• Calcifying coral abundance near low-pH springs: implications for future ocean acidification (2012, background): “…metabolic activities and result in lower growth rates (Atkinson et al. 1995; Jokiel et al. 2008; Cohen and Holcomb 2009); another idea is that high nutrient concentrations could provide energetic resources that may offset deleterious effects of high CO2 (Jokiel et al. 2008; Cohen and Holcomb 2009).”
• The impact of seawater saturation state and bicarbonate ion concentration on calcification by new recruits of two Atlantic corals (2011, background): “If the seawater in the calcifying space starts with elevated [HCO3 ] and lowered [CO3 ], the coral must expend more energy to reach a given Xar (Cohen and Holcomb 2009).”
• Reviewing the Effects of Ocean Acidification on Sexual Reproduction and Early Life History Stages of Reef-Building Corals (2011, background): “While gametogenesis may proceed normally, a recent study found that spawning female corals are significantly more susceptible to the negative effects of ocean acidification than spawning male corals [52], leading the authors to conclude that the energetically costly process of egg production leaves ”
