<i>Symbiodinium</i> cell counts in <i>A. tenuis</i> juveniles kept at 28, 30, or 31°C and under high light (a, 390 µmol photons m⁻² s⁻¹) or low light (b, 180 µmol photons m⁻² s⁻¹) levels.

<p>The number of cells was calculated from 10 replicate counts for each of 12 samples per treatment per day. Cell counts (±1 SE) were normalized to the number of polyps taken by each sample.
