Scientists have developed a scalable “holdfast-graft” method to reseed Tasmania’s lost giant kelp forests. By binding hatchery kelp to other seaweed stubs, divers achieved 40× higher survival. Within a year, the grafted kelp began reproducing—kick-starting self-sustaining forests. #GreatSouthernReef

Bleaching on both the Great Barrier Reef and Ningaloo is a warning we can’t ignore. The window to protect our coral reefs is closing fast and we must act now to limit warming and safeguard these iconic ecosystems. 🔗 www.bbc.com/news/article... #CoralBleaching #MarineScience

Great Barrier Reef suffers worst coral decline on record

Reefs have been battered by cyclones and starfish that eat coral, but heat stress driven by climate change is the main cause of damage.

🚨New paper! 🌍🦈😇 What do seafloor patterns reveal about fish, fear & food webs? Tracking reef halos at Ningaloo Reef, we found they shrink in summer but grow in winter, correlated with seasonal temp and upwelling. Single snapshots don't tell the full story. Context matters! 📖 rdcu.be/ewTI1
