The study, just published in the journal Nature Communications, was led by Dr. Natalie Levy and Prof. Oren Levy from Bar-Ilan University's Mina and Everard Goodman Faculty of Life Sciences, in collaboration with Prof. Ezri Tarazi of the Technion—Israel Institute of Technology, and Prof. David Bourne of James Cook University and the Australian Institute of Marine Science.

The study introduces a method known as "a coral reef ecosystem transplant" (aCRET), where researchers transferred biomimetic terracotta tiles embedded with a diverse community of organisms—including invertebrates and beneficial microorganisms—from a healthy reef to a nearby damaged reef.

The corals from the damaged reef were then attached to these tiles. The results demonstrated notable improvements in coral health, including increased photosynthetic efficiency, higher populations of symbiotic algae, and reduced stress levels. These findings suggest that transplanting a healthy ecosystem can significantly boost coral resilience and physiological function.

The researchers designed the biomimetic terracotta tiles to replicate the complex 3D structure of natural coral reefs, providing a perfect environment for diverse organisms to thrive. After allowing the organisms to grow on the tiles for six months, the tiles—along with their rich, biologically active substrate—were transported to the damaged reef located six km away.
