Abstract
Monthly linear extension and calcium carbonate accretion were measured over a year in the Caribbean staghorn coral, Acropora cervicornis. X-radiographs were made of cross sections of branches to analyze radial growth. Correlations were made between parameters of skeletal growth and four environmental parameters monitored over the same sampling periods: temperature, daylight hours, sun hours, plankton abundance. The results indicate that linear extension does not change during the year with the possible exception of April. It is suggested that temperatures outside an optimal range (ca. 26°–29°C for staghorn Acroporas) might cause a decrease in linear extension, however. Specific accretion (mg. mm-1) does show significant variations through the year. Calcium carbonate accretion (mean specific accretion times mean linear extension, mg. tip-1) is most strongly correlated with number of sun hours. A comparison is made between diel patterns of extension and accretion and longer term measurements. It is suggested that the accretion process is probably most influenced by some activity influenced by light. There are no annual growth bands in X-radiographs of cross-sections of the branches of A. cervicornis. This may result from secondary infilling in the skeleton.
