Deposition of calcium (45Ca2+) in the coral, Galaxea fascicularis

Effect of elevated pCO2 on photosynthesis and calcification of corals and interactions with seasonal change in temperature/irradiance and nutrient enrichment

“…Active transport of calcium could be consistent with the saturation state hypothesis if the rate of calcium transport saturates at a Ca 2+ concentration above the ambient concentration of seawater as has been reported for some coral species [ Chalker , 1976; Krishnaveni et al , 1989]. Elevated pCO 2 results in an increase in the external HCO 3 − concentration so a limitation of the supply of DIC cannot be invoked to explain the decrease in calcification.…”

Occurrence, distribution, and localisation of metals in cnidarians

“…This has been demonstrated by kinetic studies on skeletal uptake of 45 Ca (Chalker, 1976(Chalker, , 1981Krishnaveni et al, 1989;Tambutte et al, 1996) and by 45 Ca transport across isolated oral epithelia . The involvement of a Ca ATPase has been shown by the effects of Ca ATPase inhibitors on skeletal uptake of 45 Ca (Krishnaveni et al, 1989;Marshall, 1996) and the identification of Ca ATPase in coral tissue (Isa et al, 1980;. A fuller understanding of the mechanisms and pathways of Ca transport will necessitate the determination of intracellular Ca 2ϩ concentrations, particularly in the cells of the calicoblastic ectoderm.…”
