AN EVALUATION OF WETLAND COMPENSATORY MITIGATION IN THE NEW YORK GREAT LAKES BASIN
(2006-12)An ongoing priority for EPA’s Wetlands Program is to determine the effectiveness of compensatory mitigation at offsetting impacts to wetlands and meeting the goal of ‘no net loss’ of wetland functions. The Army Corps of ... -
An Inventory of the Wetlands Impacted by the U.S. Navy's Proposed OLF Site in Gates County, North Carolina
(2009-04-24)The US Navy has proposed construction of an Outlying Landing Field (OLF) for carrier-landing practice, at one of five potential sites in North Carolina and Virginia. The proposed Sandbanks site in Gates County, NC is opposed ... -
Coastal Plain Pond Vegetation Patterns: Tracking Changes Across Space and Time
(2010)Coastal plain ponds are an understudied and threatened wetland ecosystem with many unique environmental attributes. Research in these ponds can investigate species-environment relationships, while simultaneously providing ... -
Connecting differential responses of native and invasive riparian plants to climate change and environmental alteration.
(Ecol Appl, 2015-04)Climate change is predicted to impact river systems in the southeastern United States through alterations of temperature, patterns of precipitation and hydrology. Future climate scenarios for the southeastern United States ... -
Discharge competence and pattern formation in peatlands: a meta-ecosystem model of the Everglades ridge-slough landscape.
(PLoS One, 2013)Regular landscape patterning arises from spatially-dependent feedbacks, and can undergo catastrophic loss in response to changing landscape drivers. The central Everglades (Florida, USA) historically exhibited regular, linear, ... -
Ecological Assessment of the Flamingo Mangroves, Guanacaste, Costa Rica
(2011-04-29)Mangroves are tropical and subtropical ecosystems found in intertidal zones that provide vital ecosystem services including sustenance of commercially important fishery species, improvement of coastal water quality through ... -
Ecological restoration of rich fens in Europe and North America: from trial and error to an evidence-based approach.
(Biol Rev Camb Philos Soc, 2015-02)Fens represent a large array of ecosystem services, including the highest biodiversity found among wetlands, hydrological services, water purification and carbon sequestration. Land-use change and drainage has severely damaged ... -
Emerging contaminant or an old toxin in disguise? Silver nanoparticle impacts on ecosystems.
(Environ Sci Technol, 2014-05-06)The use of antimicrobial silver nanoparticles (AgNPs) in consumer-products is rising. Much of these AgNPs are expected to enter the wastewater stream, with up to 10% of that eventually released as effluent into aquatic ecosystems ... -
Emerging Issues in Wetland Loss Mitigation: A Policy Analysis in the Tar-Pamlico Basin
(2006)Ecological functions of wetlands and streams provide valuable services to human societies, but conflicting societal objectives at times place greater value on conversion or destruction than on preservation of wetlands. ... -
Environmental conditions influence the plant functional diversity effect on potential denitrification.
(PLoS One, 2011-02-02)Global biodiversity loss has prompted research on the relationship between species diversity and ecosystem functioning. Few studies have examined how plant diversity impacts belowground processes; even fewer have examined ... -
Hidden Loss of Wetlands in China.
(Current biology : CB, 2019-09)To counter their widespread loss, global aspirations are for no net loss of remaining wetlands [1]. We examine whether this goal alone is sufficient for managing China's wetlands, for they constitute 10% of the world's total. ... -
Investigating the Spatial and Quantitative Impacts of Stream Restoration on Riparian Soil Properties in the North Carolina Piedmont
(2009-04-23)One of the prime objectives of restoration is to alter the biotic and abiotic components of a system in a way so as to promote the revitalization of ecosystem functions and characteristics similar to those of undisturbed ... -
Legacy source of mercury in an urban stream-wetland ecosystem in central North Carolina, USA.
(Chemosphere, 2015-11)In the United States, aquatic mercury contamination originates from point and non-point sources to watersheds. Here, we studied the contribution of mercury in urban runoff derived from historically contaminated soils and ... -
Local Wetland Protection in the Hudson Valley
(2010-04-29)A 2001 US Supreme Court decision limiting the scope of Section 404 of the Clean Water Act by eliminating federal authority over isolated wetlands has shifted the burden for regulating wetlands to states and local governments. ... -
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 ... -
Physical and Program Options for the Inland Migration of Louisiana's Coastal Wetlands in Response to Relative Sea Level Rise
(2012-04-26)Louisiana contains over a third of the coastal wetlands in the contiguous US, but has seen a drastic reduction in total wetland area in the last century. This loss is especially troubling for coastal Louisiana where wetlands ... -
Remote Sensing of Fire, Flooding, and White Sand Ecosystems in the Amazon
(2009)Human and natural disturbance affect the Amazon basin at several spatial and temporal scales. In this thesis, I used satellite-detected hot pixels to examine patterns of human-caused disturbance and protected areas in the ... -
Restoring a River of Grass: Everglades policy recommendations for a climate change alternative
(2008-04-24)One of the largest and most extensive wetland systems in the United States is contained within the Florida Everglades National Park. Like most of the world’s wetlands it has been reduced to half of its size and heavily ... -
Restoring diversity after cattail expansion: disturbance, resilience, and seasonality in a tropical dry wetland.
(Ecol Appl, 2011-04)As the human footprint expands, ecologists and resource managers are increasingly challenged to explain and manage abrupt ecosystem transformations (i.e., regime shifts). In this study, we investigated the role of a mechanical ... -
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 ...
