Eben Broadbent has an article published in the August issue of Ecological Applications based on his master's research titled Recovery of forest structure and spectral properties after selective logging in lowland Bolivia. This article is also featured in the photo gallery of this month's ESA bulletin.
Eben and Angelica Almeyda continued to work in Bolivia and Peru on rainforest ecological and land-use change processes.
In August, Greg and Robin Martin worked for two weeks in the rainforests of Northern Australia, collecting tree species for our global tropical biodiversity project.
Paulo Oliveira, Chris Carlson, and Rebecca Raybin continued to work on the Peru remote sensing studies. Matt Jones worked on Hawaiian invasive species.
Dr. Ulrike Seibt has departed (July 9) to take up the remainder of her Marie Curie Fellowship at Cambridge University.
Dr Roland Pieruschka was just awarded a Marie Curie Fellowship and will take her desk.
Adam Wolf, a Ph. D. student just attended the Climate System Modeling Workshop held by NCAR at Breckenridge, CO, and is currently attending a Summer Graduate Workshop on Data Assimilation for the Carbon Cycle being held in Berkeley.
Three Stanford undergraduates are conducting internships this summer with the Jasper Ridge Global Change Experiment headed by Chris Field. All three students are contributing to an experimental study that examines effects of elevated soil nitrogen, phosphorus, and atmospheric CO2, and their interactions, on plant communities grown in mesocosms. Rebecca (Becca) Sorenson is majoring in Human Biology with an area of concentration in evolution and behavior. She is analyzing the biomass and carbon:nitrogen content of seeds of four species to determine whether these traits vary depending on the growth environment of the maternal plant. Rebecca will be a senior in the fall. Michael Alyono is working with Ben Houlton to analyze nitrogen isotopes in plant tissue from four species to compare them in terms of nitrogen sources for growth. Michael will be a freshman in the fall. Brandon Cortez will be a junior and is working with Todd Tobeck and Noel Gurwick to determine whether global change treatments alter the amount of carbon stored in the soil. Nona Chiariello
July 10: Ken Caldeira participated in Michael Krasny's Forum program on KQED radio this morning. The topic was ocean acidification.
Caldeira also taught a class on modeling carbon geochemistry and isotopes at the 3rd Urbino Summer School on Paleoclimatology ("Dynamics and Evolution of Cenozoic Climate"), held in Urbino, Italy in late July and early August.
Aug. 5: Ken was widely quoted in an article titled Paradise Lost in the August 5 issue of New Scientist. He argues how ocean acidification caused by the absorption of CO2 can destroy coral beds with the accompanying loss of habitat for much marine life. Photos in the article are beautiful. And again in the 31 August 2006 issue of Nature, p. 979.
Aug. 28: An article in the September issue of Scientific American titled High-Altitude Wind refers to Caldeira’s calculations of how wind power varies with altitude, latitude and season. Because wind power is greatest in the jet stream (about 10,000 meters over the US), three high-flying designs are in active development.
Dave wrote this from the large city of Manaus, which sits where the Rio Negro meets the Amazon River. He planned to be there for a few days before taking a boat up the Amazon River and into Peru.
