Research Interests
My interests are in the processes that control the exchange of gases between the terrestrial land surface and the atmosphere. I have studied whole-plant transpiration and responses to water stress in forest, desert, and riparian ecosystems, as well as the effects of species differences in water relations on whole ecosystem fluxes. I have also used stable isotope tracers as integrators of the processes that influence plant gas exchange and biogeochemistry. My goal is to apply an understanding of these aspects of plant physiological ecology and ecosystems ecology toward quantifying the effects of global environmental change on terrestrial ecosystems and the services they provide to society. As a result, I have studied changes in ecosystem water and carbon balances in response to drought, elevated atmospheric CO2, and other disturbances. Recently, I have become interested in urbanization and the ecology of human-dominated systems.
Current projects include:
Past projects have included:
- Species differences in water uptake in response to drought stress
- Quantifying canopy conductance from sap flux measurements
- Effects of elevated CO2 on plant water relations
- Changes in soil respiration under elevated CO2
- Controls on biosphere-atmosphere exchange of stable isotopes
