Table S4. Alkalinity and oxygen saturation in respiration chambers from Common reef-building coral in the Northern Red Sea resistant to elevated temperature and acidification.
Coral reefs are currently experiencing substantial ecological impoverishment as a result of anthropogenic stressors and the majority of reefs are facing immediate risk. Increasing ocean surface temperatures induce frequent coral mass bleaching events—the breakdown of the nutritional photo-symbiosis...

Coral reefs are currently experiencing substantial ecological impoverishment as a result of anthropogenic stressors and the majority of reefs are facing immediate risk. Increasing ocean surface temperatures induce frequent coral mass bleaching events—the breakdown of the nutritional photo-symbiosis with intracellular algae (genus: Symbiodinium ). Here, we report that Stylophora pistillata from a highly diverse reef in the Gulf of Aqaba showed no signs of bleaching despite spending 1.5 months at 1–2°C above their long-term summer maximum (amounting to 11 degree heating weeks) and a seawater pH of 7.8.
