This course focuses on a survey of physiological approaches to understanding plant-environment interactions from the functional perspective. Lectures cover physiological adaptation; limiting factors; resources acquisition/allocation; photosynthesis, carbon, energy balance; water use and relations; nutrient relations; linking physiology; stable isotope applications in ecophysiology; stress physiology; life history and physiology; evolution of physiological performance; physiology population, community, and ecosystem levels.

Course focuses on principles and applications of stable isotope chemistry as applied to the broad science of ecology. Lecture topics include principles of isotope behavior and chemistry, and isotope measurements in the context of terrestrial, aquatic, and marine ecological processes and problems. Students participate in a set of laboratory exercises involving preparation of samples of choice for isotopic analyses, the use of the mass spectrometer and optical analysis systems, and the anlaysis of data.

Prof. Gerlein-Safdi is an ecohydrologist interested in understanding water-carbon relations within the soil-plant-atmosphere continuum. She uses an array of methods, from satellite data to process-based modeling, from stable isotopes lab experiments to field measurements.

1) Satellite-based mapping of wetlands to improve methane emissions modeling
2) Understanding the effects of soil warming on vegetation water and carbon fluxes
3) Dew and fog as a water resource for vegetation

The Center for Stable Isotope Biogeochemistry (CSIB) on the University of California, Berkeley campus, is an analytical facility established as a University education, research, training and service unit beginning in January 2000. Facility operations are overseen by an operations manager and spectroscopist (Wenbo Yang), the faculty director (Todd Dawson), an associate researcher (Stefania Mambelli), and a steering committee. Student assistants help in daily operations and administrative support is provided by the Department of Integrative Biology.
