Dave Breshears is working within the Institute of the Environment to integrate a diverse set of activities in ecological dynamics and biogeochemistry that span the University of Arizona. His own research focuses on interactions among woody and herbaceous plants in the context of the grassland/forest continuum, ecological and hydrological interrelationships, impacts of drought and fire, water and wind erosion, and more recently, biophysical scaling relationships and new technology for measuring soil carbon. His research has been applied to a diverse set of assessments in areas including contaminant-related risks, land management, and global change.
