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.
The role of dust on snow and other aeolian inputs in biogeochemical cycling in barren, alpine catchments
Poster Number: 185 Presenter/Primary Author: Natalie Mladenov Many alpine areas are experiencing deglaciation and biogeochemical changes driven by temperature rise and changes in atmospheric deposition.
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
Soil aggregates and organic matter dynamics in short, medium and long term cover crops based land use system
Poster Number: 172 Presenter/Primary Author: Wakene Chewaka Introducing cover crops to corn and soybean cropping systems have both ecological and agricultural benefits.
Variation in carbon cycling impacts of an invasive grass (Microstegium vimineum) across an urban-rural gradient in Southern Appalachian forests
Poster Number: 157 Presenter/Primary Author: Matt Craig Although there is broad recognition that invasive species can alter ecosystem processes, little is known about how other factors influence such impacts.
