A cost-effective method for reducing soil disturbance-induced errors in static chamber measurement of wetland methane emissions
(Wetlands Ecology and Management, 2016-08-01)© 2015, Springer Science+Business Media Dordrecht. Static chambers used for sampling methane (CH 4 ) in wetlands are highly sensitive to soil disturbance. Temporary compression around chambers during sampling can inflate ... -
A five year study of floristic succession in a restored urban wetland
(Ecological Engineering, 2013-12-01)The Stream and Wetland Assessment Management Park (SWAMP) project created a wetland-stream complex that encompasses a wide array of micro-environments and hydrology. These diverse habitats were designed to facilitate ecosystem ... -
A multi-scale approach to prioritize wetland restoration for watershed-level water quality improvement
(Wetlands Ecology and Management, 2010-12-01)Wetland restoration is commonly presented as an important strategy for maintaining and enhancing the water quality and ecological capital of watershed-scale ecosystems. Prioritizing restoration sites on the landscape is ... -
Coastal freshwater wetland plant community response to seasonal drought and flooding in Northwestern Costa Rica
(Wetlands, 2011-08-01)Wetlands in tropical wet-dry climates are governed by distinct and extreme seasonal hydrologic fluctuations. In this study, we investigated the plant community response to seasonal flooding and drought in Palo Verde Marsh, ... -
Different plant traits affect two pathways of riparian nitrogen removal in a restored freshwater wetland
(Plant and Soil, 2013)Background & aims: Plants may have dissimilar effects on ecosystem processes because they possess different attributes. Given increasing biodiversity losses, it is important to understand which plant traits are key drivers ... -
Does an ‘iron gate’ carbon preservation mechanism exist in organic–rich wetlands?
(Soil Biology and Biochemistry, 2019-08-01)© 2019 Recent research suggested that iron oxidation may protect carbon from drought-accelerated decomposition in wetlands by promoting the sorption of lignin derivatives and decreasing phenolic oxidase activities. Here ... -
Dual controls on carbon loss during drought in peatlands
(Nature Climate Change, 2015-01-01)© 2015 Macmillan Publishers Limited. Peatlands store one-third of global soil carbon. Drought/drainage coupled with climate warming present the main threat to these stores. Hence, understanding drought effects and inherent ... -
Effects of exotic Spartina alterniflora on vertical soil organic carbon distribution and storage amount in coastal salt marshes in Jiangsu, China
(Ecological Engineering, 2017-09-01)© 2017 Elsevier B.V. Coastal wetlands soil organic carbon (SOC) plays an important role in global carbon sequestration, and exotic S. alterniflora affects the coastal ecosystem's functions including SOC storage (SOCS). We ... -
Errors in greenhouse forcing and soil carbon sequestration estimates in freshwater wetlands: a comment on Mitsch et al. (2013)
(Landscape Ecology, 2014-01-01)© 2014, Springer Science+Business Media Dordrecht. Radiative forcing feedbacks from wetlands have been an important component of past climate change and will likely be so in the future, so accurately assessing the carbon ... -
Human-soil relations are changing rapidly: Proposals from SSSA's cross-divisional soil change working group
(Soil Science Society of America Journal, 2011-11-01)A number of scientists have named our age the Anthropocene because humanity is globally affecting Earth systems, including the soil. Global soil change raises important questions about the future of soil, the environment, ... -
Influences of Coal Ash Leachates and Emergent Macrophytes on Water Quality in Wetland Microcosms
(Water, Air, and Soil Pollution, 2017-09-01)© 2017, Springer International Publishing AG. The storage of coal combustion residue (CCR) in surface water impoundments may have an impact on nearby water quality and aquatic ecosystems. CCR contains leachable trace elements ... -
Integrated stream and wetland restoration: A watershed approach to improved water quality on the landscape
(Ecological Engineering, 2011-01-01)Water quality in Upper Sandy Creek, a headwater stream for the Cape Fear River in the North Carolina Piedmont, is impaired due to high N and P concentrations, sediment load, and coliform bacteria. The creek and floodplain ... -
Long-term transformation and fate of manufactured ag nanoparticles in a simulated large scale freshwater emergent wetland.
(Environ Sci Technol, 2012-07-03)Transformations and long-term fate of engineered nanomaterials must be measured in realistic complex natural systems to accurately assess the risks that they may pose. Here, we determine the long-term behavior of ... -
Quantification of Peat Thickness and Stored Carbon at the Landscape Scale in Tropical Peatlands: A Comparison of Airborne Geophysics and an Empirical Topographic Method
(Journal of Geophysical Research: Earth Surface, 2019-12-01)©2019. The Authors. Peatlands play a key role in the global carbon cycle, sequestering and releasing large amounts of carbon. Despite their importance, a reliable method for the quantification of peatland thickness and volume ... -
Response of fungal communities to fire in a subtropical peatland
(Plant and Soil, 2021-09-01)Purpose: Wildfire, an increasing disturbance in peatlands, could dramatically change carbon stocks and reshape plant/microbial communities, with long-lasting effects on peatland functions. Soil fungi are important in controlling ... -
Riparian Habitat Dissimilarities in Restored and Reference Streams are Associated with Differences in Turtle Communities in the Southeastern Piedmont
(Wetlands, 2014-01-01)© 2014, Society of Wetland Scientists. Few studies have assessed whether restored streams and riparian floodplains support reference communities of certain groups of freshwater organisms, such as turtles. This exploratory ... -
Spatial Impacts of Stream and Wetland Restoration on Riparian Soil Properties in the North Carolina Piedmont
(Restoration Ecology, 2011-11-01)Hydric soil development of riparian wetlands is primarily influenced by the hydrologic connection between the floodplains and the stream channel. Often, the goal of riparian restoration is to revitalize this connectivity ... -
Suspended Sediment Mineralogy and the Nature of Suspended Sediment Particles in Stormflow of the Southern Piedmont of the USA
(Water Resources Research, 2019-01-01)The majority of annual sediment flux is transported during storm events in many watersheds across the world. Using X-ray diffraction, we analyzed the mineralogy of grab samples of suspended sediment during different stages ... -
The Effects of Organic Matter Amendments on Greenhouse Gas Emissions from a Mitigation Wetland in Virginia’s Coastal Plain
(Wetlands, 2015-10-14)© 2015, Society of Wetland Scientists. There is concern that widespread restoration and/or creation of freshwater wetlands may present a radiative forcing hazard because of the potential for methane (CH 4 ) emissions. Yet ...
