Abstract

A SCUBA-based fast repetition rate fluorometer (FRRF) was used to study differences in the functional absorption cross-section of Photosystem II (σ_PSII) between areas of a coral colony of Astreopora myriophthalma that were infested with spionid polychaetes vs areas lacking worms. The mean value of σ_PSII in infested areas (mean±SD=347.62±30.67 Å²) was significantly higher than in the areas that were not infested (316.32±17.49 Å²; P<0.0001). Several physiological mechanisms are discussed that may contribute to the observed differences.
