B.A., Biological Sciences, University of California, Santa Barbara, 1988

Research interests: (1) Biogeography and range boundaries – what are the limiting processes? (2) Ecology, distribution, and biodiversity of chaparral and desert scrub bird species in California – what are the effects of climate change, fire, and habitat fragmentation? (3) Breeding versus wintering ecology of neotropical migrants – how do factors in the wintering environment affect the ecology of the breeding season, and vice versa? (4) Status and habitat requirements of the Gray Vireo (Vireo vicinior).
My dissertation research examines how breeding distributions of bird species shift along an arid elevation gradient undergoing rapid climate change. I am comparing current distribution data to historical data collected 25 and 100 years ago along the gradient between the Colorado Desert and Peninsular Ranges in southern California. Within this large-scale distribution context, I am also testing for differences in breeding performance at distribution margins. My research is supported by several funding sources, including: the Biological Impacts of Climate Change in California Research Grant from PIEREA California Energy Commission and PRBO Conservation Science, the California Department of Parks and Recreation, the California Desert Research Fund from The Community Foundation, the Mildred E. Mathias Graduate Student Research Grant from the UC Natural Reserve System, the Mewaldt-King Student Research Award from the Cooper Ornithological Society, and the Ralph W. Schreiber Ornithology Research Award from the Los Angeles Audubon Society.
