Grasslands in Asia and North America differ in their responses to drought, according to a paper in the journal Nature led by faculty at Colorado State University. The findings show that differences in the dominant grasses and lower species diversity in the Eurasian Steppe grasslands may make it more vulnerable to drought than the North American Great Plains.
