A KAUST-led study reveals unexpectedly high functional diversity in arid and grazed dryland plants globally, examining traits like mineral element concentration in over 300 species across six continents. The research indicates that plants employ diverse adaptation strategies to aridity and grazing, with trait diversity increasing beyond a certain aridity threshold. More than half of the trait diversity was found in the most arid and grazed drylands, challenging the view that harsh conditions reduce plant diversity. Why it matters: This study highlights the ecological value of drylands and suggests plants possess unappreciated resilience to climate change, with implications for conservation and greening programs in regions like Saudi Arabia.
A KAUST-led study in *Nature Ecology & Evolution* finds that plant species diversity is the strongest predictor of dryland ecosystem resistance to grazing pressure, outperforming climate and soil factors. Analyzing 73 sites across 25 countries, researchers found that diverse plant communities better maintain vegetation cover under grazing. This is attributed to varied species responses distributing grazing pressure and buffering vegetation loss. Why it matters: The findings highlight the importance of biodiversity in maintaining the productivity and stability of dryland ecosystems, which support half of global livestock production and a billion people's livelihoods.
KAUST's Center for Desert Agriculture led Saudi Arabia to observe Fascination of Plants Day (FOPD) for the first time in the GCC. The global event, initiated by the European Plant Science Organization (EPSO), aims to raise awareness about the importance of plants and plant science. KAUST's research focuses on food, water, and the environment, addressing challenges of growing plants in extreme conditions. Why it matters: This highlights KAUST's role in advancing agricultural research and promoting environmental awareness in the region, crucial for addressing food security challenges in arid climates.
Professor Catherine McFadden of Harvey Mudd College discussed coral reef biodiversity at KAUST, noting that only about 10% of coral reef species have been described. Her research indicates that many Red Sea coral species are unique and not closely related to Indo-Pacific species as previously thought. Genetic analysis has revealed that species identification based on appearance alone is flawed, impacting conservation efforts. Why it matters: Understanding the genetic diversity of Red Sea corals is crucial for effective conservation strategies in the face of climate change and coral bleaching.
KAUST researchers are contributing new information about desert and mangrove plants to support Saudi Arabia's Green Initiative. They are creating a soil atlas for Saudi Arabia, studying soil profiles and microbial populations in hyperarid regions. The team has also compiled the world’s largest biobank of desert microbes, sequencing each microbe's genome. Why it matters: This research is crucial for ensuring the success and sustainability of large-scale greening efforts in arid environments like Saudi Arabia.
KAUST held its third annual Plant Science Family Night on February 19, 2025, hosting over 1,000 attendees from the KAUST community. The event featured 25 interactive stations covering topics like composting, genetics, recycling, and irrigation. Participants included representatives from the Center of Excellence for Sustainable Food Security, the KAUST School, and other organizations. Why it matters: This event promotes STEM education and engagement with sustainability issues among families in the KAUST community.
KAUST researchers undertook a week-long expedition in May 2017 from Al-Lith, Saudi Arabia to explore the biodiversity of the Red Sea. The expedition involved 35 participants, including KAUST faculty and 10 international marine scientists, and collected over 3,000 specimens. Over 50 species not previously recorded were found during the expedition. Why it matters: Cataloging the Red Sea's biodiversity is crucial given increasing development and provides insights into how marine organisms adapt to extreme conditions, which can inform climate change predictions.
