INTEGRATING CELLULAR PHYSIOLOGY, RECIPROCAL TRANSPLANTS AND REEF BIOGEOCHEMISTRY TO DECIPHER THE MECHANISMS FOR CORAL CALCIFICATION AND PHOTOSYNTHESIS.
There is growing concern about the future of coral reefs and the impact of anthropogenic stressors including eutrophication, ocean acidification, and warming. However, the lack of knowledge of fundamental coral cellular mechanisms precludes our ability to understand and predict general and species-specific responses to stress. Conversely, results from controlled laboratory experiments are not necessarily relevant for corals in the field, where environmental conditions may change dramatically from one reef site to the next, limiting our ability to implement appropriate management decisions. Using an integrated set of field studies, including sampling of corals from different environments and reciprocal transplants between sites and depths, with manipulative single stressor aquarium studies, immunohistochemistry, and ecosystem level biogeochemical studies, we are trying to better understand mechanisms underlying coral calcification and photosynthesis. We will present results from studies in Bocas del Toro, Panama, with support from the NSF. The overall approach was to study recently discovered cellular mechanisms related to calcification and photosynthesis in three coral species, Orbicella franksi (Robusta), Acropora cervicornis (Complexa), and Porites furcata (Complexa) at two field sites with different environmental conditions, as well as in aquarium studies. The goal is to assess the relevance of these cellular mechanisms in nature and to identify biomarkers of coral physiology that can eventually be used to monitor and predict responses to stress.
