Dear ECOLOG community, I want to bring your attention to the ninth installment of "B74. The Bio- atmospheric N cycle: N Emissions, Transformations, Deposition, and Ecosystem Impacts". This session, co-convened by Stuart Weiss, Meredith Hastings, and myself is a great venue for examining ecosystem impacts and feedbacks associated with atmospheric nitrogen deposition (see abstract below). Abstracts are due AUGUST 4th, meeting is December 5-9. Confirmed speakers include: Ronald Cohen (UC Berkeley), Jim Sickman (UC Riverside); Edith Bai (UC Davis); and Beth Holland (NCAR).
B74. The Bio-atmospheric N cycle: N Emissions, Transformations, Deposition, and Ecosystem Impacts Biogenic and anthropogenic emissions of reactive nitrogen (Nr) are transported and chemically transformed and deposited on land and water, altering ecosystem structure and function and degrading environmental quality. Estimating atmospheric N exchange, emissions, deposition, and ecosystem responses require a diverse array of methods that link processes at multiple scales. We seek presentations on physical, chemical, biological, and anthropogenic processes that drive local, regional and global nitrogen exchange, impacts on ecosystem structure, function, carbon uptake, nitrogen export, biodiversity, human health, and the fate of deposited Nr, as well as policy implications and responses. http://sites.agu.org/fallmeeting/ Hope to see you there, Emily Emily M.
