William Burger, Robert Van Pelt, David E. Grandstaff, Guan Wang, Temuulen T. Sankey, Junran Li, Joel B. Sankey, Sujith Ravi
2023, JGR Earth Surface (128)
Aeolian sediment transport occurs as a function of, and with feedback to ecosystem changes and disturbances. Many desert grasslands are undergoing rapid changes in vegetation, including the encroachment of woody plants, which alters fire regimes and in turn can change the spatial and temporal patterns of aeolian sediment transport. We...
