ACE Basin National Wildlife Refuge Forest Inventory and Carbon Stock Analysis
(2021-12-08)The ACE Basin National Wildlife Refuge (NWR) is 11,815 acres of critical wildlife habitat in South Carolina’s Lowcountry region. The Refuge contains a mosaic of forest types, including upland pine and hardwood, bottomland ... -
Development of a System for Real-Time Measurements of Metabolite Transport in Plants Using Short-Lived Positron-Emitting Radiotracers
(2008-07-29)Over the past 200 years, the Earth's atmospheric carbon dioxide (CO2) concentration has increased by more than 35%, and climate experts predict that CO2 levels may double by the end of this century. Understanding the mechanisms ... -
Duke Forest Carbon
(2011-12-09)Duke University is dedicated to achieving climate neutrality by 2024. With over 7000 acres of sustainably managed forest land, the Duke Forest has great potential for generating “in house” carbon offsets to help reach this ... -
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 ... -
Emissions Trading: EU ETS, US Voluntary Market & Carbon Credit Projects As Offsets
(2008-04-25)This project examines the Kyoto Protocol-based European Union Emissions Trading Scheme (EU ETS), the current US voluntary carbon market, and the role of carbon credit projects as offsets within emissions trading programs. ... -
Examine Agricultural Land Use Practices and Their Effects on Carbon Storage and Flux in the United States
(2022-04-22)The terrestrial ecosystem has provided a net carbon sink, equal to 20% of total greenhouse gas (GHG) emission from industrial activities in the past three decades, yet many land use activities, mainly agriculture, can drastically ... -
Growth and physiological responses of isohydric and anisohydric poplars to drought.
(J Exp Bot, 2015-07)Understanding how different plants prioritize carbon gain and drought vulnerability under a variable water supply is important for predicting which trees will maximize woody biomass production under different environmental ... -
Measurement and Modeling of Radiation and Water Fluxes in Plantation Forests
(2009)An increasing number of experimental studies attempt to maximize biomass production of trees in plantations by removing nutrient and water limitations. The results from these studies begin to inform operational managers. ... -
Old growth Afrotropical forests critical for maintaining forest carbon
(Global Ecology and Biogeography, 2020-10-01)Aim: Large trees [≥ 70 cm diameter at breast height (DBH)] contribute disproportionately to aboveground carbon stock (AGC) across the tropics but may be vulnerable to changing climate and human activities. Here we determine ... -
Physical Oceanographic Controls on Biological Production and Ocean-Atmosphere Carbon Flux in the North Pacific
(2011)This dissertation identifies and quantifies the impact of processes driving two biogeochemical phenomena of interest by considering them in the context of the large-scale circulation in which they occur. Both processes ... -
Private Landowner Participation in the Carbon Market: Opportunities in North Carolina
(2008-04-21)In response to the growing awareness of climate change across the globe, innovative conservationists have begun employing market approaches to capture the true value of carbon emissions and encourage sequestration. The most ... -
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 ... -
Restoring Farmland to Wetlands: The Potential for Carbon Credits in Eastern North Carolina
(2008-04-22)Rising atmospheric CO2 levels and the resulting global warming have created interest in storing carbon in land and biomass. Wetlands that are currently drained for agriculture have lost much of their historically stored ...
