Professional Changes
Aug. 26, Lisa Moore successfully defended her Thesis titled "The effects of global change on a California annual grassland: imperical and modeling approaches." She has been monitoring the experimental plots in the Jasper Ridge Biological Preserve for several years. First, she collected biochemical data to analyse the possible effects of elevated CO2 on warming, nitrogen deposition, precipitation and carbon balance. Then she worked with a model system to determine what future effects may be. Lisa has now accepted a Lokey Fellowship to work at Environmental Defense for one year in their Climate and Air Program, located in NYC. Her work will involve researching and writing reports on regional impacts of climate change, and putting together broadly readable materials about climate change for a variety of audiences. Congratulations!

In a move that elevates the already acclaimed Jasper Ridge Biological Preserve, Stanford University appointed Christopher Field, professor of biological sciences and director of the Carnegie Institution’s Department of Global Ecology, as the program’s new faculty director. 
Todd Tobeck has accepted a position as DGE Laboartory Coordinator. His new responsibilities include: 1)  Coordination of laboratory space utilization in the DGE building.  2)Coordination of access to departmental lab equipment. 3) Oversight of maintenance of departmental laboratory equipment.  4) Oversight (with Glenn Ford) of hazardous waste management in the DGE labs.  5) Oversight (with Kathi Bump) of safety training for the labs and the shop. 6) Oversight of ongoing safety procedures in the labs and shop.   7) Provide guidance in locating and taking advantage of laboratory resources at Carnegie and in the broader community.  8) Assist with design and construction of new laboratory instruments.

Ken Caldeira taught geochemical modeling of the long-term carbon cycle at the Urbino Summer School in Paleoclimatology in Urbino, Italy. Each summer, the University of Urbino organizes a paleoclimate related short course, designed for an international set of  graduate students and post-doctoral researchers. This summer's theme was "The Cenozoic Record of Paleoclimate Change: Reconstruction and Modeling Techniques." The modeling section of the course focused on how the  land surface determines river fluxes to the ocean, which affects ocean composition and thereby atmospheric composition, which in turn affects climate and thus the land surface, affecting river fluxes to the ocean. Understanding the dynamics of this feedback loop is critical to understanding the dynamics of long-term climate change. In constructing models, the consequences of mass and energy balance assumptions are predicted; comparison of these predictions with observations limits the set of viable hypotheses explaining past climate change. Urbino, the birthplace of the painter Raphael, is a medieval city, now largely a university town, on the UNESCO list of World Heritage Sites.
Halton Peters is in Beijing, China after recently being awarded a research fellowship by the Northeast Asia Office of the United Nations Industrial Development Organization (UNIDO). The activities of this Office encompass China, Mongolia, North Korea, and South Korea. Dr. Peters activities included investigation of the potential for China to meet its 2020 goals on sustainable development through increased participation in the Clean Development Mechanism (CDM) of the Kyoto Protocol, and participation in the development of a program aimed at building capacity for implementation of the CDM in China. In this capacity, he led a team in presenting recommendations for CDM priority areas to China's highest ministry, the National Development and Reform Commission (NDRC). In addition, he was a contributing author to a forthcoming book on industrial competitiveness in Western China, where his emphasis was on elucidating connections between industrial development and environmental quality.
Eben Broadbent just returned from four week's field work in Costa Rica. He was working on a joint project with Angelica Almeyda and William Durham from StanfordAnthropological Sciences to study the socio-economic impacts of tourism on the Osa Peninsula of Costa Rica. In addition to 70 interviews with local households, they are conducting an intensive analysis of land use and cover-changes in the area using satellite imagery from the last 20 years.
David Kroodsma is planning to bike through South America to raise awareness of climate change. You may follow his his trip on <www.thegreatridesouth.com>.
Jason Funk writes from New Zealand to call attention to an article he has written for Ecosystem Marketplace. He has been studying how NZ may function under the Kyoto Protocol, especially the Maori people who have traditionally been stewards of their lands. See <http://ecosystemmarketplace.net> for more info.
Kim Cahill writes that she is working with five winegrowers in Sonoma and Napa counties in a pilot field study of the effects of climate  on vine phenology (life-history timing) and grape chemical composition. She has also been conducting interviews with winegrowers and winemakers regarding their management practices and how they impact wine quality. These projects will feed into her dissertation, an analysis of the impacts of climate change on the premium Northern California wine industry from ecological and social perspectives. In addition Kim is
training to cycle 111 miles in El Tour de Tucson to raise awareness and funds for leukemia and other blood cancer patients, and to help find treatments for these diseases.

August 19: During our usual Tea Time, Chris led a Weeding Party with tea & bagels afterward. Numerous invasive species (weeds) had found their way among our native grasses and other plants. Dave Lobell, visiting from Livermore, joined in, and Ismael not only pulled weeds, but cleaned up the mess afterwards. Thanks to all we're looking good!
Aug. 3, Sharon Robinson, from the University of Wollogong, Australia spoke on Surviving under the Ozone Hole, Antarctic Mosses & UV-B radiation. Sharon received her doctorate from Duke Univ. and is a specialist in stress physiology. The Antarctic soil is very low in organic nutrients, and what there is comes mostly from birds and animals. The ozone hole has caused relatively high UV-B radiation, especially in the spring and early summer (September to February). Also global warming has extended the season by causing the snow covering to melt earlier. Her studies are concerned with several moss species and their photoprotective pigments. Sharon also treated us to a slide show of Antarctic scenery, especially icebergs.
Also on Aug. 3, we heard two more speakers, Guy Marion, currently a graduate student from the Centre for Marine Studies at the Univ. of Queensland, Australia, and Stacy Jupiter, a graduate student at UC Santa Cruz. Guy was an undergraduate at Stanford Univ. They are working together on Mackay Whitsunday water quality and coral-mangrove ecosystem linkages since European colonization.
