Dawn Woodard Fall 2014 With increasing concern over changing climate arises the need for better understanding of ecosystem responses and impacts on society. Fire is a key variable in this context, emitting an estimated 2-4 Pg of carbon into the atmosphere annually, and resulting in billions of dollars lost each year in property damage, suppression costs, health effects, and modified ecological services. Through my current work I hope to improve fire modeling and determine the most relevant predictors of temporal and spatial fire patterns, contributing to a better understanding of these often detrimental events and how they interface with societal and environmental systems. I am particularly interested in the interplay between anthropogenic predictor variables and fire parameters. This work will increase the accuracy of models and help us to understand what can be expected under future climate and development levels. It will also demonstrate what factors may be key in fire mitigation or prevention strategies.
Kristal Verhulst Winter 2014

As the Winter 2014 Cicerone Fellow, Kristal will examine the sensitivity of CO levels over the South Pole to changes in various sources and will seek to understand how the CO abundance at the South Pole relates to mean level in the Southern Hemisphere. This project will contribute directly to Kristal’s dissertation by providing her with better insight for interpreting the South Pole CO record. This project will also offer Kristal hands-on experience working with a 3D atmospheric chemistry model and conducting sensitivity experiments. The knowledge and skills she gains will provide her with a broader view of atmospheric chemistry and can be applied to the study of, and interpret variations in, other reactive trace gas species in future projects.

Elizaveta Litvak Spring 2012 Measured the water fluxes in situ for commonly planted tree species and turfgrass in the Los Angeles metropolitan area and gathered a critical mass of data and empirically obtained parameters. Compare measured plot-scale ET with model-based estimates and work on scaling up plot measurements to landscape ET.
Francesca Hopkins Fall 2011 Add microbial measurements to the soil incubations to better understand the microbial processes that control the response of soil carbon decomposition to warming and altered substrate availability. Determine how these global change treatments altered the composition and size of the microbial community, how the community processed new carbon inputs to soil and which microbial groups were responsible for this change.
