A study co-authored by KAUST researchers and published in Science analyzes the intertwined climate and biodiversity crises, noting that human activities have altered roughly 75% of land and 66% of marine waters. Greenhouse-gas emissions amount to over 55 gigatonnes of carbon dioxide equivalent per year, with global mean temperature increased by over 1.1 degrees Celsius since the preindustrial era. The study proposes an ambitious approach including emissions reduction, restoration, and cross-institutional alliances. Why it matters: This highlights KAUST's contribution to global research on pressing environmental challenges and informs strategies for regional sustainable development initiatives.
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.
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.
A photography exhibition titled "KAUST, an Oasis for Birds" showcased the 240 bird species residing on the KAUST campus during the 2017 Winter Enrichment Program. The exhibition featured the work of Marios Mantzourogiannis and Brian James, highlighting common and rare bird species in KAUST's habitats. Mantzouroglannis noted that KAUST's cultural and avian diversity surprised him. Why it matters: The exhibition increased awareness of the rich biodiversity within KAUST and promoted engagement with nature and birding.
Dr. Gustav Paulay from the Florida Museum of Natural History spoke at KAUST in 2018 about the surprisingly low level of knowledge about marine biodiversity. He noted that only a fraction of the millions of marine species are currently known and described. Paulay highlighted the effectiveness of large-scale biodiversity surveys and the use of technology like mass sampling and DNA analysis to speed up species identification. Why it matters: Understanding and documenting marine biodiversity is crucial for conservation efforts and for leveraging the potential of marine resources in the Red Sea region and beyond.
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 and the National Center for Wildlife (NCW) are collaborating on research to protect Saudi Arabia's coastal ecosystems and marine economy from invasive species. They are conducting biodiversity surveys along the Red Sea and Arabian Gulf coasts, having surveyed 34 sites and collected over 10,000 samples. So far, 200 species with potential marine invasive traits have been identified, expanding the national knowledge base of marine life. Why it matters: The partnership aims to develop early detection and monitoring systems, fortifying Saudi Arabia's marine biosecurity efforts and supporting its Vision 2030 blue economy goals.
