Dr. Luiz Rocha from the California Academy of Sciences discussed the impact of climate change on coral reefs during a keynote lecture at KAUST. He highlighted the phenomenon of coral bleaching due to rising water temperatures and its devastating effects on marine ecosystems. Rocha also spoke about exploring mesophotic coral ecosystems (MCEs), or the "twilight zone," at depths of 60-150 meters. Why it matters: Understanding the impact of climate change on coral reefs and exploring deeper marine ecosystems is crucial for preserving marine biodiversity in the face of global warming.

KAUST Ph.D. student Nils Rädecker won a best student presentation award at the European Coral Reef Symposium (ECRS) 2017 for his talk on coral bleaching. Rädecker's presentation focused on the underlying mechanisms of coral bleaching and the breakdown of symbiosis between corals and endosymbiotic algae due to ocean warming. His research explores the nutrient exchange between the coral host and algal symbiont to understand why the symbiosis is disrupted. Why it matters: This award recognizes important research into coral bleaching, a critical issue for marine ecosystems in the Red Sea and globally, highlighting KAUST's contribution to addressing environmental challenges.

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.

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 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.

A KAUST-led study tracked clownfish and anemones in the Red Sea from 2022-2024, finding that extreme heat caused anemone bleaching, followed by near-total clownfish death, and then anemone death. The heatwave saw accumulated thermal stress reach 22 degrees heating weeks, far exceeding the threshold for coral bleaching. The research highlights heat risks faced by non-coral reef organisms and the need for taxon-specific thresholds to predict risks to reef symbiotic relationships. Why it matters: The Red Sea is a bellwether for climate change impacts on marine ecosystems, and this study underscores the urgency of conservation efforts like KAUST's Coral Restoration Initiative.
