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.
A KAUST-led team mapped the genome of the orange clownfish using the university's Supercomputing and Bioscience Core Labs. The genome contains 26,597 protein-coding genes and is available via the Nemo Genome DB database. The clownfish genome is one of the most complete fish genomes ever produced, comprising approximately 939 million nucleotides. Why it matters: This genomic map provides a crucial resource for understanding reef fish biology and responses to environmental changes like climate change.
KAUST researchers are developing an AI tool to classify fish species based on economic value and population growth rate, aiming to aid sustainable fisheries management in Saudi Arabia. The tool will help identify species at risk of decline, supporting marine conservation and food security goals outlined in Saudi Vision 2030. Saudi Arabia aims to increase self-sufficiency in seafood production amid declining Red Sea fish populations. Why it matters: This initiative could significantly improve fisheries management and conservation efforts in the Red Sea, informing policy decisions and supporting sustainable food production in line with national objectives.
KAUST and the National Center for Wildlife (NCW) discovered an unexpected ecosystem deep below the Farasan Bank coral reef system in the Red Sea. The deep waters were inhabited by corals, fish, and other animals thriving in low oxygen and high acidity conditions. Creatures showed coping strategies like slower swimming and healthy coral growth despite conditions normally preventing calcification. Why it matters: The discovery highlights the Red Sea's significance as a natural laboratory for studying marine resilience to climate change, expanding our understanding of how marine life adapts to extreme conditions.
Researchers in Abu Dhabi developed H-SURF, a swarm of bio-inspired robotic fish for underwater data collection. Funded by the Technology Innovation Institute (TII) and conducted at Khalifa University, H-SURF uses swarm intelligence and optical communication to minimize disturbance to marine life. The project was recently recognized with the Sheikh Hamdan bin Zayed Award for Environmental Research.
