DGE Newsletter, October 2004
Special Meeting on Oct. 25: Larry Linden from the Goldman Sachs Investment Group shared his insights into how non-profit, land conservation groups may benefit from corporate wealth and business plans. As an example, he described what his Group is doing to save a large area in the Tierra del Fuego region of South America from commercial development. GS has purchased the land and given it to the Wildlife Conservation Society, based in New York, to manage. Greg Asner suggested that Satellite Imaging may be a useful way to monitor and police the area as is being done over the Amazon Basin.
We welcome Lars Hedin who will be spending a few months with us. Lars is on the Faculty at Princeton Univ. and works on the Nitrogen Cycle.
We are pleased to announce the Fall seminar series for the Carnegie Institution of Washington's Department of Global Ecology. This year our seminars will be approximately bi-weekly, on Wednesday afternoons from 4-5 p.m., and refreshments will follow. Please join us for another great year of Global Ecology speakers.
Oct. 13 - Dan Nepstad - Woods Hole Research Center, "Feedbacks among Amazon Ecosystems, Economies, and Climate"
Dan described how unproductive deforestation may be prevented by persuading farmers to use sustainable land for agriculture.

Oct. 27 - Hal Mooney, Dept. of Biological Sciences, Stanford University, "The Millennium Ecosystem Assessment---what it is and what we learned"
The MEA was launched in 2001 to provide basic information for Organizations and Conventions responsible for specific areas of the Earth such as Biological Diversity, Desertification, Wetlands, etc. The information was to include current conditions and plausible futures for these various ecosystems. Although the final reports are not due until 2005, significant findings have already been documented. For example, the structure and functions of the world's ecosystems changed more rapidly in the second half of the 20th Century than at any other time in human history. Cloud forests, coral reefs and mangroves will probably disappear in the foreseeable future. Stay tuned.

Nov. 10 - Mark Jacobson, Dept. of Civil & Environmental Engineering, Stanford University,
"The climate and air pollution effects of aerosols"
Dec. 8 - Rodolfo Dirzo, Dept. of Biological Sciences, Stanford University, "Defaunation as a global environmental change: ecological consequences in tropical forests"

Lab. Meetings
Sustainability Days
Oct. 25: Claire Lunch led a discussion of the paper by Planboeck, Templer & Tu titled Stable Isotopes in Plant Ecology in Annu. Rev. Ecol. Syst. 2002, 33:507-59.
Several members of DGE participated in and attended the Fourth Annual International Sustainability Days Conference at Stanford from Oct. 13 through 16. On the 14th, conferees were bussed to Jasper Ridge where Chris Field and several students explained the ongoing experiments. This was followed by a barbeque and after-dinner talk by Andrew Revkin from the NY Times and a Panel addressing the problem of Academics Reaching the Public: What is Responsible Popularization and Advocacy? The difficulty of persuading News Editors and the Public to take long-term disasters such as Global Warming, seriously was brought out.
DGE hosted the Jasper Ridge Global Change Experiment Data Days on Oct. 11-12. Researchers came from Boston, Switzerland, Arizona and here at Stanford to listen to and present their data obtained from the experiments at Jasper Ridge. Short presentations were organized in groups representing studies of Carbon, Nitrogen, Plant Quality & Decomposition, Phenology & NDVI, Plant Species Interactions, Plant-Animal Interactions, Plant Genes, Microbial Genes & Community Structure, Treatments & Data Management, and Evolutionary Responses. It was an opportunity to assess where each worker's own experiments fit into the larger picture offered by this unique experimental site.
The Fall Picnic was held on Sunday, Oct. 10 from 2 to 6 PM. Kathleen Brizgys did a great job of organizing us to provide a fine variety of salads, pasta, relishes and desserts (mostly chocolate) to compliment the three, large, fresh-caught salmon that Chris and Paul grilled to perfection. Between 40 and 50 of us enjoyed the lively music of the jazz combo, Boca de Rio, from 3 to 4 PM before dinner. Weather was perfect.
