DGE Newsletter, September 2006
Field's Group
Sept. 19: Chris Field chaired the morning session titled Bioenergy Storage and Conversion as part of the Global Climate & Energy Project (GCEP) Research Symposium at Stanford. Papers in this session included Directed Evolution of Novel Yeast Species, Direct Solar Biohydrogen, Is Bioelectricity Possible, and Hydrogen Production in Cyanobacterial Heterocysts. Several Carnegie faculty were cited in these presentations including, most notably, Barbara McClintock who was supported in the Dept. of Genetics through most of her research life and received the Nobel Prize in 1983 for the discovery of transposons.
The Symposium ran from Sept. 18 to 20 and included a wide range of topics related to Energy, Carbon Dioxide and Global Warming.

First DGE Fall Seminar

Sept. 27: Dr. Beverly Law, College of Forestry, Oregon State University is the science chair of Ameriflux and an authority on scaling carbon balance in forests.  Her group was in the news recently concerning their paper in Science -- Post-Wildfire Logging Hinders Regeneration and Increases Fire Risk. The seminar was about how ecosystems respond to climate and the coupling of carbon and water.

Sept. 26: Eben Broadbent & Angelica Almeyda have sent a wonderful collection of photos taken during their recent field studies in Peru. For proof that they did more than party, paste the following into your browser: <http://picasaweb.google.com/ebennb> You may also refer to the the Archives for June 2006 Monthly News to see what they hoped to accomplish.

Dr. Law also spoke earlier to the Field Lab Group about the political controversy stirred up between the Logging Industry and her University over the scientific results of selvage logging.
Sept. 14 From Dave Kroodsma in Peru.
The journals and photos of Ride for Climate have recently passed 100,000 page loads for 2006. Every day, according to my statistics counter, between 50 and 100 different people look at the journals and photos, and there are over 300 page loads. Most of this traffic appears to be word of mouth (and not links from other sites) and return visitors.
It means a lot to me that people are following along. It means that my message – that global warming will affect all the people of the Americas – is getting out. But also, perhaps as important, these visits keep me going – when there are hard days, it is good to know that people are checking in. So, keep visiting, and keep telling your friends about Ride for Climate.
I am currently on the east side of the Andes, in a land of dirt roads, jungle, and slow internet (see map). The road I planned to take across the mountains turned out to not exist, and I am finding the route as I go. Hopefully I will be able to post another update (and upload pictures) in a week, from the city of Huaraz, on the other side of the Andes. Follow Dave at <www.rideforclimate.com>
Sept. 4: Elsa Cleland, together with co-authors Nona Chiariello, Schott Loarie, Chris Field, and Harold Mooney saw the results of their studies on climate change in relation to "complementarity" of plant communities published online in the PNAS. Using the facilities at Jasper Ridge, the authors found that species which have evolved to stagger their growth and reproductive cycles in order not to compete for limited resources, may flower at the same time under increased concentrations of CO2. This is just one way in which global warming may affect natural communities including the animals and insects within them.
Elsa is now a Post Doc at the National Center for Ecological Analysis and Synthesis in Santa Barbara, CA.
