Dave Breshears joined the University of Arizona as a Professor in 2004 in what is now the Watershed Management and Ecohydrology Program of the School of Natural Resources and the Environment. In 2018 he became a Regents Professor and in 2023 he transitioned to Emeritus status. Prior to joining University of Arizona he was with University of California for more than a decade at Los Alamos National Laboratory.  He received a B.S. from New Mexico State University (1985), and his M.S. and PhD. From Colorado State University (1987 and 1993). Breshears studies ecohydrology related to the causes and consequences of vegetation change with a focus on tree mortality and associated forest “die-off” events, emphasizing drylands but extending globally and including “ecoclimate teleconnections”—or how tree die-off in one place can affect plants in others.  He also quantifies trends in ecosystem properties as a function of woody plant cover, and transport and erosion of sediment driven by both wind and water.  Breshears applies these results to help address issues tied to climate change impacts, land use management, pollution, and ecosystem services.  In Web of Science he has been cited >32,000 times, has an h-index of 70, and has been listed as a Highly Cited Researcher in five different years. While at University of Arizona, he helped with establishing the Santa Rita Experimental Range as a core site of the National Ecological Observatory Network (or NEON); with the launching of the US National Phenology Network and locating its national coordinating office at UA;  and with the scientific vision leading to UA’s acquisition of Biosphere 2. He is a Fellow of the American Association for the Advancement of Science, the American Geophysical Union, the Ecological Society of America, the Kavli U.S. Frontiers in Science, and the Aldo Leopold Leadership Program.

This event will be held in-person in ENR2 Room S107.
