‘Shocking' coral spawning drop raises doubts over Great Barrier Reef's resilience

Spawning by dominant coral species on the Great Barrier Reef collapsed after the back-to-back mass bleaching events, stoking fresh fears about the reefs' biodiversity and resilience.

spawning levels collapse new research shows.

Not only did the amount of new baby corals crash - falling as much as 95 per cent in some parts of the north - the composition also shifted, according to research published Thursday in Nature.
