Study shows how coral develops resilience

Australia

Unprecedented back-to-back bleaching events on the Great Barrier Reef has changed the physiology of tougher coral, making them more resilient to future stress, new research suggests.

Scientists from the ARC Centre of Excellence for Coral Reef Studies looked at the impacts of bleaching in 2016 and 2017, finding that surviving coral behaved differently the second time.

“We can no longer assume that future bleaching events, in say a decade or two, will have the same effect that they have now, because of these changes in physiology in the mix of species,” lead researcher Terry Hughes told ABC radio on Tuesday.
