Isotope ratio mass spectrometer analyses of biological materials allow us to source, trace, record, and integrate activities in plants and animals through stable isotope measurements of tissues or specific compounds. Stable isotope analyses have applications in ecology, climate, forensics, and physiology.

Current research in the Ehleringer Lab at the University of Utah is maintained at a different website.
