Coral Bleaching Susceptibility Is Decreased following Short-Term (1–3 Year) Prior Temperature Exposure and Evolutionary History
Figure 4
Hemocytometry data showing the mean cumulative loss of viable (a1, b1), necrotic (a2, b2), and mitotic (a3, b3) zooxanthellae cells (×103 mL−1) expelled from Montastraea cavernosa collected from the Flower Garden Banks National Marine Sanctuary (a1–3)) and the Florida Keys National Marine Sanctuary (b1–3)) sampled every 6 h over a 72 h time period at 27°C (⚫), 31°C (▲), and 35°C (■). Error bars represent 95% confidence intervals (); some error bars are too small to be seen. Note how cumulative graphs illustrate the effect of temperature on overall depletion of a coral’s Symbiodinium complement over 72 h.
