Research Emphasis

I am very broadly interested in ecosystems in dry areas. My past work has focused largely on grasslands and I expect most of my future research to shift towards questions associated with mixtures of grasses and shrubs or in ecosystems dominated by shrubs. A portion of my research has focused on plant population and community ecology. Within these general topics, my students and I have worked on demography, controls on recruitment, resource partitioning between grasses and woody plants, responses to and recovery from disturbance ranging from small to large spatial scale including grazing by domestic livestock. Another branch of the research my students and I have conducted falls within the realm of ecosystem ecology and has included above and belowground net primary production, carbon budgets, and water balance. I use simulation modeling as a key exploratory and analysis tool across all of the organizational and spatial scales of my research.

Current Research Projects

Shortgrass Steppe Long Term Ecological Research Project
Testing controls on shrub-grass interactions in a cool temperate ecosystem
Response of the sagebrush-conifer ecotone to a mountain pine beetle epidemic and climate change
