Evaluating rhizodegradation of petroleum hydrocarbons and polycyclic aromatic hydrocarbons in wetland sediments containing spartina patens
… a former salt marsh at an active oil refinery. Spartina patens were grown in basin sediments during a field study and a greenhouse study over three consecutive growing seasons. Ninety percent (90%) survival was observed in field study plots containing sediments with <12% PHC. In the greenhouse …

RESPONSE OF A SPARTINA PATENS-DOMINATED OLIGOHALINE MARSH TO NITROGEN ENRICHMENT IN COASTAL NORTH CAROLINA, USA.
… goal of this study was to fertilize plots in a Spartina patens-dominated oligohaline marsh with varying concentrations of urea applied throughout one growing season and assess the response in aboveground and belowground plant biomass and decomposition. Aboveground plant clippings and soil cores …

The Role of Nitrogen Availability, Hydroperiod and Litter Quality in Root Decomposition Along a Barrier Island Chronosequence
… during decomposition of a common root type (Spartina patens) and native roots are discussed.</p> <p>Spartina patens roots decayed slower and lost more phosphorus in seasonally saturated swale soils than in well drained dune soils. Variation in hydroperiod between swales did not result in …

THE IMPACT OF SEA-LEVEL RISE ON COASTAL WETLANDS USING IN-SITU MESOCOSM EXPERIMENTS, LANDSCAPE MODELING, AND TRADITIONAL ECOLOGICAL KNOWLEDGE MAPPING
… on two commonly found saltmarsh species,<em> Spartina alterniflora </em>and <em>Spartina patens</em>. I examined productivity and metrics to these stressors using a controlled mesocosm experiment in the western channel of the Pascagoula River, Mississippi. I found varying strategies of growth …

Responses of a Louisiana oligohaline marsh plant community to nutrient loading and disturbance
… seasonally from April 2004 to September 2006. Spartina patens and Schoenoplectus americanus are co-dominant plant species in this marsh. Low N-loading additions resulted in increased S. patens cover. However, increased N loading did not result in a shift in plant community composition despite …

Evaluation of Nitrogenase Genes as Markers in Soil Microbial Community Studies
… in the rhizosphere of salt-meadow grass (Spartina patens), a key plant species in high salt marshes. Members of the ɛ-subdivision of Proteobacteria were shown to be prominent nitrogen-fixers in this system, with specific populations changing seasonally and in response to the presence of …

Spatial modeling and visualization of habitat response to hydrologic restoration in New England salt marshes
… salt marshes were examined: halophyte species Spartina alterniflora, Spartina patens, and Juncus gerardii, and brackish invasive species Phragmites austrahs, Typha angustifolia, and Lythrum salicaria .</p><p>The model was applied to spatial grids representing marsh area at four salt marsh sites …

Landscape analysis of vegetation change in coastal Louisiana following hurricanes Katrina and Rita
… to low vegetative cover, slow recovery of Spartina patens, and shifts towards more saline marsh classifications by fall 2007. Hydrologic barriers, including impoundments in the west, contributed to salinity and sulfide stress; however, these same structures facilitated trapping of mineral …

Developing tools to identify factors that limit production in coastal marshes
… the world. In Louisiana’s coastal marshes, where Spartina patens is the most common plant, restoration and management seek to slow wetland loss rates that average approximately 77.4 km2/year. To combat the problem, scientists and managers require tools to determine local causes and evaluate the …
