Open AccessVegetation dieback in the Mississippi River Delta triggered by acute drought and chronic relative sea-level rise
Vegetation dieback and recovery may be dependent on the interplay between infrequent acute disturbances and underlying chronic stresses. Coastal wetlands are vulnerable to the chronic stress of sea-level rise,...

Open AccessElevated temperature and nutrients lead to increased N2O emissions from salt marsh soils from cold and warm climates
Salt marshes can attenuate nutrient pollution and store large amounts of ‘blue carbon’ in their soils, however, the value of sequestered carbon may be partially offset by nitrous oxide (N2O) emissions. Global cli...

Relationships between ecosystem properties and sea-level rise vulnerability of tidal wetlands of the U.S. Mid-Atlantic
Tidal wetlands in the Mid-Atlantic, USA, are experiencing high rates of relative sea level rise, and it is unclear whether they will be resilient in the face of future flooding increases. In a previous study, ...

Sediment Accumulation, Elevation Change, and the Vulnerability of Tidal Marshes in the Delaware Estuary and Barnegat Bay to Accelerated Sea Level Rise
Tidal marshes are highly valued habitats, yet are vulnerable to loss from both anthropogenic and natural disturbances including sea-level rise (SLR). Many tidal marshes have kept pace with SLR over the last ce...

Benthic Biofilm Potential for Organic Carbon Accumulation in Salt Marsh Sediments
Coastal salt marshes are productive environments with high potential for carbon accumulation and storage. Even though organic carbon in salt marsh sediment is typically attributed to plant biomass, it can also...

High Reinvasion Potential of Phragmites australis in a Delaware River (USA) Tidal Freshwater Marsh Following Chemical Treatment: the Role of the Seedbank
Management of the invasive Phragmites australis haplotype has focused on controlling its abundance in wetlands where it reduces biodiversity. However, little information is available on establishment of native co...

Do Aquatic Macrophytes Limit the Invasion Potential of Exotic Species in Pantanal Grasslands?
Natural disturbances have the potential to limit exotic species invasions. The exotic grass, Urochloa humidicola, has high propagation potential following seasonal flooding, but, flooding tends to reduce the cove...

Open AccessRetreating marsh shoreline creates hotspots of high-marsh plant diversity
Marsh edge retreat by wave erosion, an ubiquitous process along estuaries, could affect vegetation dynamics in ways that differ from well-established elevation-driven interactions. Along the marshes of Delawar...

Spartina patens Productivity and Soil Organic Matter Response to Sedimentation and Nutrient Enrichment
Many coastal wetlands are subject to the combined effects of reduced sediment input and increased nutrient loads from watersheds. Restoration strategies focused on increasing marsh elevation and acreage can in...

Seed bank of seasonally flooded grassland: experimental simulation of flood and post-flood
Wetland seed banks comprise the propagules of plant species that have species-specific germination requirements for germination in either flooded or dry conditions. At the community level, wetland structure an...

Influence of Physical Manipulations on Short-Term Salt Marsh Morphodynamics: Examples from the North and Mid-Atlantic Coast, USA
Along the mid- and north Atlantic coasts of the USA, over 90 % of salt marshes have been ditched. Ditching was largely abandoned by the mid-twentieth century; however, techniques that create permanent shallow ...

Differential population response of allocation, phenology, and tissue chemistry in Spartina alterniflora
Phenotypic variation within species is widespread among salt marsh plants. For Spartina alterniflora, the dominant species of low intertidal wetlands across the Altantic and Gulf coasts of the US, distinct phenol...

Nitrogen Pools of Macrophyte Species in a Coastal Lagoon Salt Marsh: Implications for Seasonal Storage and Dispersal
High nitrogen (N) loading rates received by coastal bays can have deleterious effects on aquatic ecosystems. Salt marshes can intercept land-based N through seasonal plant uptake, denitrification, and burial. ...

Salt Marsh Carbon Pool Distribution in a Mid-Atlantic Lagoon, USA: Sea Level Rise Implications
The distribution of carbon (C) within a salt marsh may vary among vegetation zones depending on production and decomposition dynamics and organic and mineral depositional history. We examined spatial and tempo...
