Researchers from KAUST and the University of Padova studied how hyperoxia, or excessive oxygen supply, extends heat tolerance in marine ectotherms. The study, published in Science Advances, examined the role of photosynthetic organisms like seagrasses in producing oxygen in aquatic habitats. They found that increased oxygen availability helps coastal marine animals like crabs, sea cucumbers, and shellfish increase their resilience to rising temperatures. Why it matters: Understanding the interplay between oxygen levels and temperature tolerance can inform strategies for preserving marine ecosystems in the face of global warming.
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.
A team from KAUST attended the 9th International Symbiosis Society Congress in Oregon, U.S. in July. Hagen Gegner, a KAUST Ph.D. student, presented work on the role of high salinity in the thermotolerance of corals. He reflected on the pros and cons of presenting unpublished research, balancing transparency with potential exposure of sensitive findings. Why it matters: The participation of KAUST researchers in this international congress highlights the university's focus on marine biology and symbiosis, fostering collaboration and knowledge sharing in a competitive scientific field.
KAUST marine biologist Maggie Johnson is studying how to accurately measure environmental conditions to optimize coral restoration, focusing on temperature and light. She highlights the variability in precision and accuracy of commercially available instruments for measuring these parameters. Johnson notes that some instruments fail in the Red Sea's warm temperatures and high salinity, providing incorrect data. Why it matters: Accurate environmental monitoring is crucial for the success of coral reef restoration efforts in the face of climate change, especially in extreme environments like the Red Sea.
A KAUST and King Abdulaziz University research team is using superhydrophobic sand to grow crops like tomatoes with less water. Superhydrophobic sand reduces water consumption in agriculture, the world's largest consumer of freshwater. The sand was developed by KAUST's Himanshu Mishra and Ph.D. student Adair Gallo Junior. Why it matters: This research offers a promising solution for water conservation in agriculture, especially in arid regions like the Arabian Peninsula, addressing critical water security challenges.
