From: Effects of cold stress and heat stress on coral fluorescence in reef-building corals
Correlations between green fluorescence and dinoflagellate population characteristics.
Green fluorescence was significantly correlated with (a) dinoflagellate density in non-bleached corals and in bleached corals, (b) effective quantum yield in non-bleached corals and in bleached corals, (c) maximum quantum yield in non-bleached corals and in bleached corals and (d) pressure over PSII (Qmax) in non-bleached corals and bleached corals. Solid lines represent correlations between green fluorescence and non-bleached corals and dashed lines represent correlations between green fluorescence and bleached corals. Chlorophyll measurements could not be obtained for the heat treatment at 20 d due to the large reduction in dinoflagellate density (see Methods).
