KAUST researchers have conducted the first measurements of deep-sea corals in the Red Sea. They retrieved specimens of three different species at depths of 300-750 meters and temperatures exceeding 20 degrees Celsius. This discovery challenges the existing understanding that deep-sea corals are exclusive to cold-water environments. Why it matters: The research expands known ecosystem boundaries for deep-sea corals and demonstrates their resilience in warm, nutrient-poor waters, offering new insights into marine biodiversity and adaptation.
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.
