| Summary: | As carbon dioxide (CO 2 ) levels increase, coral reefs and other marine systems will be affected by the joint stressors of ocean acidification (OA) and warming. The effects of these two stressors on coral physiology are relatively well studied, but their impact on biotic interactions between corals are poorly understood. While coral-coral interactions are less common on modern reefs, it is important to document the nature of these interactions to better inform restoration strategies in the face of climate change. Using a mesocosm study, we evaluated whether the combined effects of ocean acidification and warming alter the competitive interactions between the common coral Porites astreoides and two other mounding corals ( Montastraea cavernosa or Orbicella faveolata ) common in the Caribbean. After 7 days of direct contact, P. astreoides suppressed the photosynthetic potential of M. cavernosa by 100% in areas of contact under both present (~28.5°C and ~400 μatm p CO 2 ) and predicted future (~30.0°C and ~1000 ... : This dataset comes from a tank experiment. Data was collected using PAM flourometry and photography. Photos were processed in Image J. Data was analyzed in R. ... |
