Figure 5.

Pulsed amplitude modulation (PAM) fluorescence yield of dark-adapted Acropora millepora colonies from five populations over the time course of the experiment in each temperature treatment. Values are means of 18 nubbins±s.e. Magnetic Island: red, open circle; Davies native: green, open triangle; Davies transplants: blue, filled triangle; Keppels native: pink, open square; Keppels transplants: orange, filled square. Post hoc comparisons: black star, significant difference (α=0.002) between the mean of Magnetic Island and Keppel transplants colonies (containing D zooxanthellae) compared to native Keppel colonies (containing C2 zooxanthellae) and black circle, mean of Magnetic Island and Keppel transplants colonies compared to the mean of Davies and Davies transplant colonies (containing C2^* zooxanthellae).
