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.
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.
