Figure 7. Coral growth and bioerosion as functions of temperature anomaly in west (W) and east (E), 7 m and 20 m depth.

Coral growth rate of Porites lutea nubbins at all study sites (n = 20, df = 1, F-value = 4.4, r² = 0.46, p = 0.039) along the Similan island chain after 12 months exposure (February 2007 to February 2008; see Fig. 4) (A), and bioerosion (calculated mass change in calcium carbonate (CaCO₃) corrected for accretion due to fouling organisms) on CaCO₃ blocks at the central Similan island Ko Miang (see Fig. 1) after 12 months (grey depiction; February 2007 to February 2008; n = 4, degrees of freedom = 1, F-value = 14.4, r² = 0.30, p<0.001) and 21 months exposure normalized to 1 year (February 2007 to November 2008; n = 4, degrees of freedom = 1, F-value = 17.9, r² = 0.58, p<0.001) (see Fig. 5; <0, bioerosion) (B) as functions (GLM) of the cumulative negative temperature anomaly (calculated as °C d) of the respective time period. All values are plotted as mean ± SE.
