Tradeoffs to Thermal Acclimation: Energetics and Reproduction of a Reef Coral with Heat Tolerant Symbiodinium Type-D

Figure 2

Symbiont community changes in colonies of Acropora millepora following a bleaching event in February 2006. (a)–(c). Two of the original 12 C2 colonies changed to type D symbionts, one colony recovered with C2 and D, one colony changed to D and C1, three colonies changed to C1, and three colonies recovered with both C2 and C1 symbionts. (d)–(f). Ten of the original D colonies retained their D symbionts, one colony changed to C1, and one colony gained C1 symbionts.
