KAUST researchers have found that the symbiotic relationship between corals and micro-algae is 100 million years older than previously thought, dating back 160 million years. The study suggests that corals have endured numerous climate change events due to their biological characteristics. Researchers developed an updated naming scheme using genetic techniques to identify different micro-algal symbionts. Why it matters: This discovery offers a glimmer of hope for coral survival in the face of modern global warming and enhances conservation efforts, while also modernizing coral symbiont taxonomy.
KAUST researchers are studying coral reefs in the Northern Red Sea, which exhibit unusual heat tolerance, surviving temperatures 5°C above the mean summer maximum. This resilience makes them a potential refuge for coral, offering a "climate change insurance" for the next 100 years. Researchers aim to understand the mechanisms behind this thermotolerance to aid coral conservation efforts globally. Why it matters: Understanding and preserving these unique coral reefs could provide crucial insights and strategies for protecting coral ecosystems worldwide in the face of rising ocean temperatures.
KAUST researchers demonstrated that Beneficial Microorganisms for Corals (BMC) can help corals recover from thermal stress by stimulating immune processes and rebuilding their microbiome. The study, published in Science Advances, showed that probiotic treatments can protect bleached corals from death. The research was conducted at the Federal University of Rio de Janeiro (UFRJ) and the KAUST Red Sea Research Center, with funding from the Great Barrier Reef Foundation and the Tiffany & Co Foundation. Why it matters: This finding offers a promising solution for mitigating the impacts of climate change on coral reefs, which are vital ecosystems facing increasing threats from warming ocean temperatures.
KAUST researchers have discovered that a coral's resilience to rising temperatures is determined by the microorganisms living inside them. The study identifies specific combinations of microeukaryotes and bacteria that enhance heat resistance in corals. This finding provides valuable clues for developing coral probiotics to protect and restore coastal reefs. Why it matters: This breakthrough could lead to effective interventions to combat coral bleaching and preserve vital marine ecosystems in the Red Sea and beyond.
KAUST researchers from the Red Sea Research Center are studying mesophotic reefs (40-150m deep) as potential climate refuges for corals threatened by marine heatwaves. These deeper reefs experience less heat and light stress compared to shallow-water corals. Advanced tools like submarines and robots are now enabling the study of these previously neglected ecosystems. Why it matters: Understanding the resilience of Red Sea corals could provide crucial insights for global coral reef conservation strategies amid climate change.
