But UVic scientists have discovered that some corals can survive prolonged heat waves, particularly if they don’t face other human-caused stressors, such as water pollution and bacteria. It’s the first time corals have been observed recovering from bleaching while a heat wave persists. Julia Baum, a UVic marine biologist and the study’s senior author, called the discovery “a game changer.” “This provides a little bit of good news that corals, or at least some types of corals, may be able to survive under heat stress for longer than we thought,” Baum said. Heat stress usually cau...

Some corals managed to survive a recent and globally unprecedented heatwave, according to new research. Coral reefs serve important ecological functions, from providing habitat for countless species to protecting shorelines from erosion. Reef-dependent fisheries are also a vital source of food and income for hundreds of millions of people in tropical island nations where coral reefs are valued at $6.8 billion annually. “Although this pathway to survival may not be open to all corals or in all conditions, it demonstrates an innovative strategy for survival…” The pressing concerns of clim...
