Fall 2012 American Geophysical Union Meeting

December 3 - December 7 @ - San Francisco, CA

Abstract: Dryland ecosystems comprise > 40% of the terrestrial surface and are home to more than one third of the global population. These ecosystems are under great pressure to support exponentially increasing human populations in the face of changing climate. Ecosystem perturbations resulting from land uses (e.g., grazing, altered fire regimes) and global changes (e.g., elevated CO2, temperature, rainfall amount and seasonal distribution) can impact both above- and belowground processes resulting in changes to soil organic matter stocks, biogeochemical processes, soil fertility, erosion and desertification, changing microbial and plant community structure and biodiversity, and shifting ecosystem boundaries due to phenomena such as woody plant encroachment. This session will bring together scientists to discuss the biogeochemical response of dryland systems to punctuated and progressive ecosystem stress.
