A multilevel model of field-scale nitrogen export from agricultural areas

Jones, Phillip (2010-04-27)

Agricultural lands contribute significant nitrogen loads to surface waters. Excessive nitrogen input leads to eutrophication, the process by which aquatic ecosystems become nutrient rich. Eutrophication is associated with ...

Ecosystem recovery from acid precipitation: Carbon and nitrogen cycling in the soil-stream continuum

Marinos, Richard (2018)

While the problem of acid precipitation has been greatly reduced across the developed world, acid-impaired ecosystems still bear important legacies of historic acid deposition, and these ecosystems are only slowly beginning ...

Functional Traits Exert More Control on Root Carbon Exudation than Do Short-Term Light and Nitrogen Availability in Four Herbaceous Plant Species

Thorsos, Eileen Roseanne (2011)

Root carbon exudation is a critical element of the soil carbon cycle, and how both environmental conditions and plant traits influence exudation remains uncertain. I studied relationships between environmental conditions, ...

IDENTIFYING POTENTIAL TIME LAG RESPONSES THROUGH LONG-TERM WATER QUALITY TRENDS IN A RESTORED RIPARIAN WETLAND STREAM COMPLEX IN THE PIEDMONT OF NORTH CAROLINA

Dunn, Autumn (2021-04-29)

Restoration of impaired ecosystems often experience hydrological and biogeochemical time lags between the restoration implementation and ecosystem recovery and water quality improvements, but there is a lack of long-term ...

Leaf Traits, Neighbors, and Abiotic Factors: Ways That Context Can Mediate the Impact of Invasive Species on Nitrogen Cycling

Lee, Marissa Ruth (2016)

Species invasions are more prevalent than ever before. While the addition of a species can dramatically change critical ecosystem processes, factors that mediate the direction and magnitude of those impacts have received ...
