Microanalysis of C and O isotopes of azooxanthellate and zooxanthellate corals by ion microprobe (2003, unknown): “The range of pH measured by this method is about one unit between 8.13 and 9.29 on calicoblastic layers and between 7.93 and 8.74 in the coelenteron (Al-Moghrabi et al. 2001; Al-Horani et al. 2003).”
Comparing the impact of high CO2 on calcium carbonate structures in different marine organisms (2011, background): “Investigations principally of molluscs (Wilbur 1964; Erez 2003) but also of corals (Al-Horani et al. 2003; Erez 2003), barnacles (Bubel 1975) and echinoderms (Decker & Lennarz 1988) show that bicarbonate (HCO3 ) or CO2(aq) and not carbonate (CO3 2 ) is the origin of the carbon used in calcification.”
Cell Biology of Cnidarian-Dinoflagellate Symbiosis (2012, background): “To test this, AlHorani and coworkers (2) directly measured the pH and calcium concentration in the ECM with an invasive microelectrode, and they recorded an alkaline pH ranging from 8.”
Energetic cost of photoinhibition in corals (2006, methodology): “Previous studies of light-enhanced respiration in corals have demonstrated a 6- to 12-fold 8 P ho to sy nt he si s Hoogenboom et al.: Energetic cost of photoinhibition in corals increase in oxygen consumption following light exposure (Kuhl et al. 1995, Al-Horani et al. 2003).”
Biological mechanisms supporting adaptation to ocean acidification in coastal ecosystems (2015, unknown): “Physiological evidence (Al-Horani et al., 2003 and Venn et al., 2011) and boron isotope compositions of coral skeletons (Trotter et al., 2011, Holcomb et al., 2014) have confirmed that there is an absolute increase of pH relative to seawater during active calcification.”
Effects of changing seawater temperature on photosynthesis and calcification in the scleractinian coral Galaxea fascicularis , measured with O 2 , Ca 2+ and pH microsensors (2005, methodology): “In addition, much of the CO2 released by respiration is fixed by photosynthesis and thereby the pH is maintained higher in light than in dark (Al-Horani et al., 2003b).”
The reef coral two compartment proton flux model: A new approach relating tissue-level physiological processes to gross corallum morphology (2011, background): “Ca++ can diffuse from seawater to the coelenteron (Al-Horani et al., 2003b), but metabolic energy is needed for transport of Ca++ across the calicodermis into the enclosed space that forms the skeleton.”
