| Research Focus | |
|
My research examines the physiological responses of plants and ecosystems to climate change. The primary focus is on the effects of anthropogenically altered patterns of rain and snowfall on plant and ecosystem functions. This includes the integration and scaling of experimental approaches at the cellular, tissue, organismal, population, and ecosystem levels. Our main study site is at the ecotone between Sierra Nevada conifer forest and Great Basin Desert sagebrush steppe, near Mammoth Lakes, California. We work closely with the Bureau of Land Management, the National Park Service, the National Forest Service, Caltrans, the City of Los Angeles Department of Water and Power, Inyo County Water, and the Mammoth Community Water District, to help inform managment decisions in the region where we work. I also collaborate with colleagues at a number of other desert and subalpine research sites in studies of how other global changes (including elevated carbon dioxide, increased temperature, and nitrogen deposition) will affect plants and ecosystems. |
