Research Statement


Humans are having an ever-increasing influence on Earth, resulting in global changes that impact ecological systems and ecological cycles. These global changes include altering the trace gas composition of the atmosphere, changing the abundances and distributions of water and nutrients, and facilitating the spread of invasive species. In the Ehleringer Lab, we studied the interactions among the global change drivers, ecosystem form and function, and the responses of plant species. Our experimental approaches included physiological flux measurements, stable isotope analyses, and geographic information system (GIS) modeling. Student and postdoc research included animal physiology, anthropology, diet reconstruction, and fundamental forensic science interests.
