DOIAbstract
This study focusses on the nature and extent of variation in mycosporine-like amino acids (MAAs) in relation to annual cycles in solar radiation, seawater temperature, and reproduction in reef-flat populations of two soft coral species. The results show MAA tissue concentrations in shallow water colonies of Lobophytum compactum and Sinularia flexibilis to be significantly correlated to annual cycles in solar radiation (P<0.0006 and P<0.0005, respectively) and seawater temperature (P<0.0006 and P<0.0004, respectively). Evidence of seasonal cycles in MAA levels in the tissues of shallow-reef invertebrates positively correlating with annual cycles in solar radiation and temperature suggests that they are an integral component of the soft coral...
