High summer temperatures amplify functional differences between coral‐ and algae‐dominated reef communities

摘要: This is the data to "High summer temperatures amplify functional differences between coral- and algae-dominated reef communities". All information on how dataset was collected can be found in manuscript.  Abstract of manuscript: Shifts from coral algal dominance are expected increase tropical reefs as a result anthropogenic disturbances. The consequences for key ecosystem functions such primary productivity, calcification, nutrient recycling poorly understood, particularly under changing environmental conditions. We used novel situ incubation approach compare communities central Red Sea bi-monthly over an entire year. In gross net community dissolved organic carbon fluxes, inorganic nitrogen their respective activation energies were quantified describe effects seasonal changes. Overall, coral-dominated exhibited 30% lower productivity 10 times higher calcification than communities. Estimated indicated thermal sensitivity these communities, negatively correlated with temperature (>40% >65% reduction, respectively, +5°C winter summer), while losses via respiration release more doubled at temperatures. contrast, summer, fluxes unaffected. These results suggest pronounced changes functioning associated phase shifts. Algae-dominated may outcompete due retention support fast biomass accumulation compromising formation important framework structures. Higher likely differences, indicating high vulnerability even below bleaching thresholds. Our that ocean warming not only cause but also coral-algal shifts reefs.
