Juvenile coral responses to thermal and nutritional treatments. (a) Growth (% planar extension day⁻¹); (b) tissue thickness (µm); (c) Symbiodiniaceae fluorescence (RI) of juvenile Pocillopora acuta corals in rearing temperature (x-axis) and nutrition (purple = unfed; orange = fed) treatments. Error bars indicate the standard error of mean. p-values indicate significance (black text = p < 0.05, grey text = p > 0.05). (d) Representative examples of juvenile corals from each treatment under LSCM. Cyan indicates coral tissue fluorescence, magenta indicates Symbiodiniaceae fluorescence. Scale bars indicate 0.5 mm.
