Diana Tomback is Professor of Integrative Biology at the University of Colorado Denver. Her expertise includes evolutionary ecology, with application to forest ecology and conservation biology. She is known for her studies of Clark’s nutcracker, a bird of high mountain forests, and its interaction with several white pine species, particularly whitebark pine, leading to her election in 1994 as Fellow of the American Ornithologists' Union. Her research over time has revealed major ecological and evolutionary consequences to pines from avian seed dispersal, including growth form, population structure, regeneration biology, and the effects of exotic disease and mountain pine beetles on the bird-pine mutualism. Tomback was lead organizer and editor of the book, Whitebark Pine Communities: Ecology and Restoration, published by Island Press in 2001. This latter work has grown in significance, with the recent status review of whitebark pine under the Endangered Species Act by the U.S. Fish and Wildlife Service. Dr. Tomback’s current research involves studies of the functional role of whitebark pine at treeline, and the effects of whitebark pine mortality on seed dispersal by Clark’s nutcracker in the central and northern Rocky Mountains. In 2001, Tomback together with several colleagues started the Whitebark Pine Ecosystem Foundation, a 501 (c)(3) non-profit based in Missoula, MT. The WPEF is dedicated to the restoration of whitebark pine ecosystems and educating the public and resource management agencies about the importance of this pine. She has served as volunteer Director of this organization since its inception.
