KAUST researchers collaborated with international scientists to propose a nature-based adaptive approach for coral restoration, published in Nature Reviews in Earth & Environment. The review emphasizes enhancing specific components of the coral holobiont to maximize the natural adaptive capacity of corals to survive climate change. It advocates for customized protection approaches based on the reef's degradation, location, and traits. Why it matters: This research offers a critical roadmap for preserving coral reefs, which are vital ecosystems threatened by climate change, by leveraging the corals' natural adaptive mechanisms.
KAUST researchers are using 3D printing with a novel calcium carbonate ink to create coral support structures that accelerate coral restoration. Their approach, named 3D CoraPrint, involves printing coral microfragments onto the structure, offering a head start for reef recovery. Two methods were developed: printing a mold for reproduction and direct printing for customization. Why it matters: This eco-friendly technique provides a potentially scalable solution to combat coral reef degradation, leveraging advanced materials and fabrication for ecological conservation in the region and beyond.
KAUST researchers are studying corals in the Red Sea and Arabian Gulf that are more tolerant of high temperatures. They are mating corals from different parts of the world, assuming that the offspring will be more heat-resistant. Using a commercial coral spawning system, the researchers can time coral spawning to cross colonies that would not naturally cross. Why it matters: This research aims to identify genes responsible for temperature resilience and use selective breeding to increase coral resilience in the face of rising ocean temperatures.
The KAUST Coral Restoration Initiative (KCRI) is planning for a transformative 2025, focusing on digital twins and land-based nurseries, according to KCRI chief scientist Professor David Suggett. The KCRI eCoral™ digital twin will use AI and machine learning for coral restoration, scenario modeling, and decision-making. KCRI's reef-based nurseries can produce up to 100,000 corals per year for transplantation. Why it matters: AI-powered coral reef restoration can help create more resilient ecosystems and inform environmental policymaking in the region.
A KAUST study explains how corals control their symbiotic algae using nutrient competition, tracking carbon and nitrogen isotopes. The research shows that cnidarians limit nitrogen available to the algae, preventing overgrowth and maintaining a balanced symbiosis. This mechanism evolved independently in corals, sea anemones, and jellyfish. Why it matters: The findings have implications for coral reef restoration efforts like the KAUST Reefscape Restoration Initiative by disrupting traditional views of symbiosis.
