In many parts of the world, staple crops such as maize and wheat are dependent on rainfall recycled from land rather than oceans, making them more vulnerable to drought. Researchers at Stanford and the University of California San Diego identified a critical threshold in atmospheric moisture sources that could help predict and prevent future crop failures.
Young umbrella acacia trees in Africa survive severe drought by putting their natural processes into overdrive when water is in short supply, prioritizing continued growth over water conservation, new research shows. The study is the first genome-scale analysis of any African acacias and focuses on the umbrella acacia, an iconic feature of the African savanna.
