What to know about Ningaloo Reef corals reveal early fall spawning window for two key species

Scientists from Curtin University have identified the spawning windows for two key Porites coral species at Ningaloo Reef. The research emphasizes that understanding reproductive timing is critical for measuring reef recovery and implementing effective restoration efforts following climate-driven heat waves.

What happened

Ningaloo Reef corals reveal early fall spawning window for two key species Sadie Harley Scientific Editor Robert Egan Senior Editor Curtin University scientists have uncovered an important missing piece in the puzzle of how some coral reefs can recover from…

Why it matters

Researchers visited Ningaloo Reef off the Western Australian coast to investigate Porites corals, a group of reef-building corals that play a major role in creating and maintaining reef habitats throughout the Indo-Pacific.

Common ground

For the first time, the team was able to determine when some of Ningaloo Reef's most important corals reproduce, creating a benchmark that will help scientists track the effects of marine heat waves, assess reef recovery and identify opportunities for…
