Israeli Scientists Offer Breakthrough in Reviving Coral Reefs

Scientists in Israel, collaborating with Australian researchers, have unveiled a groundbreaking method to restore dying coral reefs, offering new hope for marine ecosystems threatened by climate change. This innovative approach, called the coral reef ecosystem transplant (aCRET), demonstrates how healthy reef ecosystems can rejuvenate damaged ones.

Led by Dr. Natalie Levy and Prof. Oren Levy from Bar-Ilan University, along with Prof. Ezri Tarazi of the Technion Israel Institute of Technology, and Australian experts from James Cook University and the Australian Institute of Marine Science, the study was recently published in Nature Communications. It introduces a pioneering method that leverages biomimetic terracotta tiles to transfer healthy ecosystems directly to degraded reefs.

The terracotta tiles, designed to mimic the intricate 3D structure of natural coral reefs, were embedded with a thriving community of invertebrates and beneficial microorganisms. After six months of development on a healthy reef, these biologically enriched tiles were relocated to a damaged reef six kilometers away. Corals from the damaged reef were then attached to these tiles.

The results were remarkable. Corals transplanted to the healthy substrate exhibited improved photosynthetic efficiency, higher populations of symbiotic algae, and reduced stress levels. In contrast, transferring substrate from the damaged reef to a healthy one produced less favorable outcomes, further emphasizing the benefits of healthy ecosystem transplants.

“Our work highlights the transformative role healthy reef ecosystems play in coral recovery,” said Dr. Natalie Levy. “This technique offers a sustainable and effective tool for restoring reefs, especially when combined with existing strategies like coral gardening and artificial reefs.”

The study underscores the versatility of aCRETs as a restoration solution that can be adapted to diverse marine environments. It is also cost-effective, making it an accessible option for areas where financial resources for marine conservation are limited. However, researchers recommend selecting nearby healthy reefs for transplantation to optimize success and call for further long-term studies to understand the broader ecological impacts.

“This research brings us closer to overcoming the global coral crisis,” added Prof. Oren Levy. “By focusing on healthy ecosystems to regenerate damaged ones, we take a significant step toward ensuring the survival of coral reefs and the biodiversity they sustain.”

As coral reefs continue to face mounting threats from climate change and pollution, innovative solutions like this transplant method provide a vital lifeline for preserving marine biodiversity and safeguarding our planet’s underwater ecosystems.
