Effects of Long-term Nitrogen Fertilization and Annual Burning on Soil Carbon and Nitrogen Dynamics in a Tallgrass Prairie

Poster Number:  191 Presenter/Primary Author:  Michael Carson Anthropogenic activities have altered virtually all ecosystems in numerous ways, often affecting carbon (C) and nitrogen (N) dynamics on local, regional and global scales.

Net Ecosystem Exchange, Soil Respiration, and the Age of Respired Carbon from High-Elevation Alpine Tundra

Poster Number:  178 Presenter/Primary Author:  John Knowles Carbon dioxide (CO2) is increasing in the contemporary atmosphere as a result of an imbalance between anthropogenic and natural CO2 emissions and biospheric and oceanic CO
