ALERT: This system is being upgraded on Tuesday December 12. It will not be available
for use for several hours that day while the upgrade is in progress. Deposits to DukeSpace
will be disabled on Monday December 11, so no new items are to be added to the repository
while the upgrade is in progress. Everything should be back to normal by the end of
day, December 12.

A multilevel model of field-scale nitrogen export from agricultural areas
(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
(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
(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
(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
(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 ... -
Modeling land use patterns and water quality: An evaluation of the pySPARROW model
(2008-04-24)Modeling the effects of land use and land cover changes on water quality is important for watershed managers to better understand how human modifications to land surfaces may alter stream nutrient loads. One model available ... -
Modeling nitrogen fate in supercritical water oxidation
(2020)Supercritical water oxidation (SCWO) had been investigated as an advanced technology for the removal of inert and stable organics found in wide range of wastes. Ammonia and nitrous oxide are confirmed in outlet of SCWO system ... -
Response of Southern Shrub Peatland Phenolics and Carbon Dioxide Flux to Drought and Nitrogen Additions
(2013-04-26)Peat forms under wetland conditions where flooding obstructs flows of oxygen from the atmosphere and reduces the decomposition rate of plant litter. Peatlands only cover three percent of land area worldwide, yet they store ... -
The Effect of Warming on Phenology, Physiology, and Leaf Nitrogen in Six Deciduous Tree Species Over the Growing Season
(2013)There is no consensus on climatic warming's effect on phenology, photosynthesis, and leaf nitrogen content in temperate deciduous tree species. A major question is whether or how these trees will utilize a longer growing ...
