KAUST scientists have successfully expanded coral spawning through controlled systems, producing approximately two million eggs from six coral species this season to support reef research. Researchers at KAUST's Coastal and Marine Resources (CMR) Core Lab developed facilities that replicate environmental signals to trigger spawning beyond natural seasonal cycles, enabling year-round access to gametes and larvae. This program represents the first successful implementation of shifted phase coral spawning in Saudi Arabia. Why it matters: This breakthrough provides unprecedented opportunities for advancing Red Sea reef restoration and marine science, allowing for continuous study of coral early-life resilience.
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.
KAUST, in partnership with NEOM, is launching the KAUST Reefscape Restoration Initiative at Shushah Island in the Red Sea. The project will restore approximately 100 hectares of reefscape by growing and planting hundreds of thousands of corals. It will also establish a research and ecotourism center. Why it matters: This initiative demonstrates Saudi Arabia's commitment to preserving coral reefs using advanced research and technology, which could have significant implications for marine ecosystem conservation in the region and globally.
A KAUST-led research team has observed intergenerational epigenetic inheritance in corals, demonstrating that corals pass patterns of DNA to their offspring. The research, published in Nature Climate Change, shows that corals can adapt to environmental changes and pass those traits on through DNA methylation patterns. This is the first time this process has been observed in animals, previously only seen in plants. Why it matters: This finding could enable biologists to train corals in nurseries to produce offspring better equipped to survive changing marine environments, aiding coral reef restoration efforts.
A KAUST-led study published in PNAS quantifies the potential for increased food supply through coral reef restoration. Analyzing over 1,200 reef sites, the research estimates that rebuilding depleted fish populations could increase sustainable yields by nearly 50%. For Indonesia, this could translate to 162 million additional servings of reef fish annually. Why it matters: The study provides crucial evidence for governments to strengthen food security and ecosystem resilience through fisheries management, especially in regions facing high malnutrition.
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.
KAUST's National Transformation Institute (NTI), led by Dr. Ian Campbell, aims to accelerate Saudi Arabia’s Vision 2030 goals by commercializing KAUST research. NTI facilitates collaborations between government, industry, and academia to create jobs and develop solutions for climate change, sustainability, and economic diversification. The institute focuses on projects like coral reef restoration, cryogenic carbon capture, and sustainable animal feed development. Why it matters: NTI's mission to translate research into real-world solutions will help to strengthen Saudi Arabia's innovation ecosystem and diversify its economy.
The KAUST Reefscape Restoration Initiative (KRRI) observed the first-ever mass synchronized coral spawning in the northern Red Sea at NEOM’s Shushah Island. In March 2023, KRRI launched on-the-reef restoration work at Shushah, propagating nearly 5,000 corals from a dozen species, nearly half of their 2023 annual target. KRRI is testing various coral propagation techniques and nursery designs, aiming to produce half a million corals per year. Why it matters: This initiative is a major step towards coral reef restoration in the Red Sea, aligning with Saudi Arabia's sustainable development goals.
