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.

Ronald Cohen focuses on developing and applying new experimental and modeling strategies for understanding the chemical composition of the Earth’s atmosphere now and in the past and for predicting future changes. He explores the chemical formation of aerosol within the atmosphere and the kinetics of cloud formation.

His projects include:
1) The relationship between evaporation kinetics and the formation of cloud droplets
2) Chemical effects on the speed of cloud droplet growth
3) Role nitrogen oxides (NOx) play in the formation of secondary organic aerosol (SOA)

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

Dr. Jones’s research uses quantitative Earth system science tools –computer models, uncertainty quantification techniques, etc. – to gain decision-relevant insight into how humans affect the climate and vice versa. Major themes include the “usability” of regional climate projections for adaptation planning, the resilience of energy, water, and food systems to multiple stressors, the role of land use change in efforts to both reduce and adapt to climate change, and the tightly coupled interactions among people, built infrastructure, and environmental processes in urban contexts.

Projects include:
1) Project Hyperion, within which he leads a stakeholder engagement process with water management professionals in four case study basins across the US aimed at evaluating and improving the decision-relevance of high-resolution climate projections for long-range water system planning
2) Efforts to understand urban environmental processes (heat waves, vegetation dynamics, hydrologic flows and their implications for energy and water resources) in the context of changing climate, land use, and demographics.

Mary Firestone’s research involves the fundamental understanding of soil microbial ecology, and applications to problems such as global change, sustainability and biodegradation. Current research interests include: bacteria/soil interactions and interactions between plant roots and soil microorganisms.

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.

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.
