, collected over a12 h period. Corals exposed to 28 to 36°C treatments. • = 28°C; ○ = 30°C;▾ = 32°C; Δ = 34°C; ▪ = 36°C. Data transformed by arcsine for normalization purposes. Zooxanthellae: No significant linear regressions at 28–34°C (p>0.05); i.e., linear regression coefficients were not significantly different from “0″. Significant deviations from linearity and non-linear response at 36°C (p<0.001; Y = 21.964+23.434*[1−e(−0745X)]). Host Cells: No significant linear regressions at 28–32°C (p>0.05); i.e., regression coefficients were not significantly different from “0”. Significant positive linear regressions at 34–36°C (p<0.05; Y = 0.979X +14.152, and Y = 1.214X +18.952, respectively).
