Fig 2. Flow-through of experimental design for experiments 1 and 2.

In Experiment 1, Symbiodinium consortia were determined for shallow and upper mesophotic Porites astreoides adult colonies and planulae. Juveniles of shallow parental origin were reared in situ on the shallow and upper mesophotic reef and were examined for specific growth rates and Symbiodinium phylotype combinations. In Experiment 2, Symbiodinium consortia and specific growth rates were determined for shallow and upper mesophotic planulae and ex situ reared juveniles.
