Welcome! Our research focuses on the impact of natural disturbances and global environmental change on mesic and arid grassland ecosystems. We are particularly interested in the interactive effects of fire, grazing and drought in mesic grasslands in North America and South Africa, and how rainfall variability, temperature change, and shrub encroachment affect aridland ecosystems in the southwestern US.

Press-pulse interactions, spatial variability and ecological state change

Check out these two recent publications on drivers and indicators of state change and recovery. This is pretty interesting. Although the models and empirical data are mostly from mesic systems, these ideas definitely apply to aridland systems as well.
