Root Production and Morphological Traits During and After Single and Repeated Extreme Droughts in a Mesic Grassland

Ingrid Slette, David Hoover, Melinda Smith & Alan Knapp
Global climate change is expected to cause more frequent extreme droughts in many parts of the world. Despite the crucial role of roots in water acquisition and plant survival, our understanding of ecosystem vulnerability to drought is primarily based on aboveground impacts. As return intervals between droughts decrease, root responses to one drought might alter responses to subsequent droughts, but this remains unresolved. We conducted a 7-year experiment that imposed extreme drought (growing season precipitation...
