Greg Barron-Gafford

Programs/Projects

Much of my work related to adaptations has focused on how natural semiarid ecosystems have responded to climatic change by way of plant physiological adaptation or shifts in community composition. I have begun a new series of experiments to test using "novel ecosystems" to make use of traditional ecological knowledge in mitigating the impacts of large-scale photovoltaic renewable energy production.
