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.

General biology of freshwater and marine algae, highlighting current research and integrating phylogeny, ecology, physiology, genetics, and molecular biology.

A study of physiological and biochemical processes in higher plants, including water relations, ion transport, and hormone physiology; photosynthesis (light utilization and carbon assimilation), nitrogen and sulfur metabolism, and plant-specific biosynthetic pathways.

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

Dennis Baldocchi focuses on biometeorology, biosphere-atmosphere trace gas fluxes, ecosystem ecology and climate change. One of the “big questions” he aims to address is what are the influences of weather and climate, the structure and function of plants and ecosystems, biological, physical and chemical properties of soils, and land management and land use change on the trace gas (H2O, CO2, 13CO2, CH4, C5H10) exchange of ecosystems?

His projects includes:
1) Coordinated use of experimental measurements and theoretical models to understand the physical, biological, and chemical processes that control trace gas fluxes between the biosphere and atmosphere and to quantify their temporal and spatial variations. The spatial scales of this work ranges from the dimension of a leaf through the depth of plant canopies and the planetary boundary layer and the horizontal extent of landscapes.

Current research in the Ackerly lab is focused on studies of climate change impacts on California biodiversity, including distribution modeling, long-term vegetation dynamics and focal studies of selected plant species. Our primary field site is the Pepperwood Preserve, Santa Rosa, CA. Graduate students and post-docs are working on evolution of physiological traits, demography of alpine plants, and species distributions on fine-scale spatial gradients.

Iryna Dronova focuses on diverse aspects of landscape ecology and its potential to inform sustainable, multi-functional landscape-designs, and decision-making in environmental planning. Her research looks into wetlands, wetland restoration, remote sensing, GIS & spatial analysis.

Her projects include:
1) Using remotely-sensed phenology to monitor biodiversity and ecosystem services in wetlands
2) Cost-effective tools for wetland restoration monitoring from local to regional scales

Peggy Lemaux focuses on both basic and applied research focused primarily on cereal crops, like sorghum, wheat, rice and barley. The objectives of these studies are to better understand crop plants and to use that knowledge to improve their performance and quality. More recently efforts with colleagues have focused on bioenergy – especially in the versatile feedstock, sorghum.

One of her projects includes:
1) “Epigenetic Control of Drought Response in Sorghum” (EPICON)
A $12.3 million Department of Energy Biological and Environmental Research-funded project to examine how the drought-tolerant cereal crop, sorghum, survives water loss.
Researchers expect to develop better predictions about how sorghum and other cereal crops are affected by future climate scenarios, leading to approaches to improve crop growth and production under water-limiting conditions.

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.

Established in 1951, Sagehen Creek Field Station is a research and teaching facility of the University of California at Berkeley located in the Central Sierra Nevada north of Truckee, California.

The station is embedded within the 9,000-acre Sagehen Experimental Forest, which is cooperatively and collaboratively managed in a partnership between the University of California, the US Forest Service’s Pacific Southwest Research Station and the Tahoe National Forest.

Sagehen serves as the hub of a broader regional network of research areas known as the Central Sierra Field Research Stations. CSFRS also includes the Central Sierra Snow Lab, Onion Creek Experimental Forest, North Fork Association Lands and the Chickering American River Reserve.
