Current Research

My research focuses on natural and human factors affecting biological diversity in a variety of terrestrial, riparian, and aquatic ecosystems in California, with particular emphasis on conservation challenges in the Lake Tahoe basin. I am currently the lead scientist on three studies that evaluate the effects of human factors on population and community processes shaping biological diversity. First, I am the lead scientist investigating patch and landscape-scale disturbance and fragmentation effects on species occurrence and abundance, population structure, and species composition of birds, mammals, and vascular plants. One product of the study will be a landscape-scale predictive model to inform the acquisition and management of undeveloped lands (urban lots) in the Lake Tahoe basin study area. Second, I am studying the effects of off-highway vehicles on vertebrate assemblages and their habitats, the results of which will inform the management of OHV use areas throughout California. Finally, I am investigating spatial and temporal effects of habitat degradation in lentic ecosystems (lakes, ponds, and wet meadows) on associated amphibian and reptile species. Completed research projects include my dissertation research, which investigated patterns of biological diversity (vertebrates, invertebrates, vascular plants, and fungi) in stream-side riparian ecosystems in the Lake Tahoe basn. I have also studied bird assemblages in oak woodlands, including inquiries into the foraging ecology of insectivorous birds, and the effects of tree density on species composition, abundance, and nest success. The results of this research were used to inform harvest regulations for oak woodlands in California. In addition to my core research program, I have a strong interest in the design and analysis of landscape-scale ecosystem monitoring. I led the design of the Sierra Nevada monitoring strategy, which encompassed a wide variety of biological and physical features: 1) populations and habitats of species of concern; 2) terrestrial and aquatic ecosystem conditions; and 3) sociocultural phenomena as integrated components of ecosystems. I am currently co-leading the development and testing of a national protocol for monitoring multiple species and their habitats (Multiple-Species Inventory and Monitoring protocol) as a tool to meet National Forest obligations to monitor Management Indicator Species.
