Erika Zavaleta
In most of her work, Erika strives to bridge ecological theory, training and research to sound conservation and management practice. To that end, her research incorporates collaboration with conservation practitioners and elements of economics, public policy, and anthropology. From 2001-2003, Erika was a David H. Smith Conservation Research Fellow of the Nature Conservancy. In 2004-05 she spent a one-year leave working in the philanthropic sector as program ecologist for The Christensen Fund.
Erika completed a BA and MA in Anthropology (1995) and a PhD in Biological Sciences (2001) at Stanford University. She was a recipient of the Ecological Society of America’s Sustainability Science Award in 2008 and has authored or co-authored ~75 papers and book chapters in ecology and social science. She lives in Santa Cruz and enjoys life outdoors with her husband and wee ones (ages 21, 11, 7, and 4). Erika Zavaleta is a professor in the Ecology and Evolutionary Biology Department at the University of California at Santa Cruz. She and her research group study the drivers and consequences of changing biological diversity and the role of ecology in guiding effective conservation practice. Recent and current projects address the effects of climate variability and change on endemic California ...
