May 3: Prof. Allen Goldstein, Dept of Environmental Science, Policy, and Management & Department of Civil and Environmental Engineering, Univ. California, Berkeley. spoke about Known and Unexplored Organic Constituents in the Earth’s Atmosphere. He talked mainly about biogenic aerosols that are produced by trees (e.g. terpenes) which are 10X greater than those produced anthropogenically. They also react together but most of the carbon in aerosols is biogenic.
May 10: Dr. Anna Sala, Professor, Division Biological Sciences, Univ. Montana, spoke to the title: The carbon-balance approach to tree growth and survival: helpful or misleading? She discussed the limitations which trees & shrubs have for carbon storage, one of which is height. Go to her Website for more info. <http://www.cfc.umt.edu/PersonnelDetail.aspx?id=904>
May 26: Jason Keller, Earth & Environmental Sciences, Chapman Univ. spoke to the title — Humic substances as key regulators of decomposition in wetland ecosystems. He has been measuring the amounts of stored carbon and methane as well as the ratio of CO2/CH4 in different peats and bogs. The results show a peatland gradient with this ratio being the greatest in bogs.
DGE In House Seminars
April 25: The DGE internal 45-minute dual seminar series started with Ken Caldeira giving us an overview of his Lab's activities. Mike Mastrandrea was the second speaker talking about what he and Kate Mach are doing with the IPCC. Jen Johnson has kindly volunteered to help coordinate speakers for this series which are planned to occur every two weeks and include all students & post-docs.
May 9: Bill Anderegg summarized his current research on Widespread forest die-off. Mainly he is working on Sudden Aspen Decline (SAD) to try to determine how climate change may affect it and similar forest species. Julia Pongratz followed with a discussion of Land use and climate - from Genghis Khan to geoengineering. She has been analyzing how humans influencing land-use as well as the Industrial Revolution have all contributed to global climate change. Other topics such as geoengineering and extreme events were also mentioned.
May 23: Rumi Asano described her work as both Lab and IT Manager for DPB & DGE. For computer related problems at DGE, she is aided by Rob & Patrick. Chris Field then filled us in on the latest results from Global Change Experiments at Jasper Ridge. These grasslands serve as an excellent model system in part because they sit on earthquake fault lines with various micro climates and soil types. The harvest this past month yielded some unusual results in that two species of thistle dominated the plots and their growth was greatly stimulated by both CO2 & nitrogen.
May 27: Becca Hernandez & Kelly McManus organized The 1st Annual DGE Women's Luncheon 2011, TO FOSTER SOLIDARITY AND SUPPORT, WELCOMES STAFF, FACULTY, AND STUDENTS OF THE DGE 12:00 to 1:30 p.m. WITH A SPECIAL ADDRESS (short talks) BY Nona Chiariello and Jan Brown, AND SPONSORED BY Starbucks & California Pizza Kitchen WITH DOOR PRIZES INCLUDING GIFT CERTIFICATES TO FRAICHE FROZEN YOGURT, BE YOGA, and THE CHEESECAKE FACTORY, Location: Plant Bio Seminar Room, Food and Beverages Provided. All are welcome!
This info had been distributed as an email flyer, and about a dozen women came to enjoy the food (on decorated tables) and conversation. Jan described some of her experiences working as a woman scientist (part time) when she joined the much smaller DPB about 50 years ago. Nona followed by noting the many improvements in the working conditions of women in science both at Stanford & Carnegie since then. Nona also gave us a most welcome introductory bio of Anna Michalak who arrives next month to be our first DGE woman faculty member. Let’s hope this type of get-together becomes a tradition. Any volunteers?
