Change in <i>Symbiodinium</i> D∶C cell ratios (±1 SE) over time in <i>Acropora tenuis</i> juveniles at 28, 30, or 31°C in: (a) high light (390 µmol photons m⁻² s⁻¹), or (b) low light levels (180 µmol photons m⁻² s⁻¹).

<p>Dotted line represents equal proportions of <i>Symbiodinium</i> types D and C cells within the juveniles. Ratios closer to 1 are dominated by type D; ratios closer to 0 are dominated by type C. N = 20 per data point.</p

Summary of total number of juveniles counted at each temperature by light treatment during the mid-experiment census (mid) and for the census at the end of the experiment (end).

Long term sea temperature at 2 m depth in Geoffrey Bay, Magnetic Island.

<p>Data was collected over 15 years (1996–2011) by loggers maintained by the Australian Institute of Marine Science (Channel ID 1820, data available from <a href="http://data.aims.gov.au/gbroosdata/services/rss/channel/923/150" target="_blank">http://data.aims.gov.au/gbroosdata/services/rss/channel/923/150</a>).</p

Repeated measures ANOVA results comparing changes in D∶C cell ratios in <i>Acropora tenuis</i> juveniles kept at three temperatures (28, 30, or 31°C) by two light levels (390 µmol photons m⁻² s⁻¹ or 180 µmol photons m⁻² s⁻¹).

<p>Within-subjects factor Day was 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20.</p

Relative survival (±1 SE) of juveniles in the 28, 30, or 31°C treatments and under high light (390 µmol photons m⁻² s⁻¹) or low light (180 µmol photons m⁻² s⁻¹) levels for: (a) <i>Acropora tenuis</i> after 20 days, and (b) <i>A. millepora</i> after 30 days.

<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.</p
