โœฆ Synopsis

Using 45Ca incorporation into the coral skeleton as a measure of calcification rate, the effect of temperature on calcification rate was studied in the hermatypic coral

Pocillopora damicornis.

Both immediate and long-term (adaptation) effects were investigated. Temperature has a marked effect on rate -an effect that varies depending on the temperature history of the coral (i.e., temperature adaptation occurs). P. damicornis showed both 27o and 31oc temperature optima, one or the other being dominant depending on the natural water temperature to which the coral was adapted. The two optimum temperatures may indicate two isoenzymes or two alternate metabolic pathways involved in the calcification process.
