Fig. 4. Skeletal calcium incorporation in Galaxea fascicularis incubated in standard filtered sea water with and without HEBP (0.5 mmol l^-1). Following incubation in HEBP, when the skeleton was dissolved before the tissues, the incorporation of calcium into the skeleton was significantly higher (^*; P<0.05), than when the skeleton was dissolved after tissue removal. There was no significant difference in calcium incorporation in polyps incubated in standard sea water alone (P>0.05), regardless of whether the skeleton was dissolved before or after tissue removal. Values are means ± S.E.M., N=5.
