Data to support surface elevation change and vertical accretion data to support assessment of hummock formation/loss in tidal freshwater forested wetlands along the U.S. Atlantic coast (2009-2021) Data to support surface elevation change and vertical accretion data to support assessment of hummock formation/loss in tidal freshwater forested wetlands along the U.S. Atlantic coast (2009-2021)
This study evaluated surface elevation change and vertical accretion of sediments in hollows and on top of hummocks associated with the base of tree stems in tidal freshwater forested wetlands. Sites were along a gradient of habitat change from freshwater forest to marsh and tracked hollow subsidence and in-filling with transgression over 6 (Virginia) to 12 (South Carolina/Georgia) years...
Sap flow, leaf water use efficiency, and partial weather station data to support stand water use modeling by nutrient treatment (N, P) for mangroves of Ding Darling NWR, Sanibel Island, Florida (2019-2020) Sap flow, leaf water use efficiency, and partial weather station data to support stand water use modeling by nutrient treatment (N, P) for mangroves of Ding Darling NWR, Sanibel Island, Florida (2019-2020)
This study evaluated sap flow of neotropical mangrove species subjected to background nutrient loading, and well as fertilization with either nitrogen or phosphorus, at Ding Darling National Wildlife Refuge (NWR). Data collections were made seasonally to model stand water use by mangrove forests as a metric of ecosystem stress through alteration of water use potential at the stand level...
Sapflow data from two separate but adjoining ecotones on Bannockburn Plantation near Georgetown, South Carolina, USA (2008 and 2009) Sapflow data from two separate but adjoining ecotones on Bannockburn Plantation near Georgetown, South Carolina, USA (2008 and 2009)
These data support a sap flow study, as represented by dual temperature differentials between heated and unheated probes inserted into trees. Data are from two separate field sites, with five tree species recorded every 30 minutes during the time periods of June 29 to August 24, 2008, and March 5 to June 1, 2009. Data were collected from a longleaf pine plantation (Pinus palustris) and a
Data for leaf photosynthesis and net ecosystem exchange of CO2 and CH4 from wetland forest, marsh, and mudflats under simulated ambient and elevated atmospheric carbon dioxide (2013-2014) Data for leaf photosynthesis and net ecosystem exchange of CO2 and CH4 from wetland forest, marsh, and mudflats under simulated ambient and elevated atmospheric carbon dioxide (2013-2014)
This study evaluated the net ecosystem exchange of CO2 and CH4 from experimental wetland mesocosms established in elevated CO2 and ambient CO2 glasshouses at the U.S. Geological Survey’s Wetland and Aquatic Research Center (Lafayette, Louisiana). The study duration was approximately two years, and these data represent measured and calculated data from four time points, which the...
Fine root production in tidally influenced freshwater forested wetlands in South Carolina and Georgia, USA (2016-2017) Fine root production in tidally influenced freshwater forested wetlands in South Carolina and Georgia, USA (2016-2017)
This dataset includes fine root productivity data that were estimated via two techniques (serial coring and root in-growth bags) in tidal freshwater wetlands and adjacent oligohaline marshes in coastal South Carolina and Georgia from March 2016 through October 2017.
Geographic distribution of black mangrove (Avicennia germinans) in coastal Louisiana in 2009 Geographic distribution of black mangrove (Avicennia germinans) in coastal Louisiana in 2009
Black mangrove (Avicennia germinans (L.) L.) has historically occurred along the Louisiana coast in saline wetland habitats, but its distribution has been sparse. Mangroves are tropical to semi-tropical species and their distribution is limited by freezing temperatures. Black mangrove distribution and abundance has increased and decreased in the coastal zone of Louisiana according to...

Framework for facilitating mangrove recovery after hurricanes on Caribbean islands Framework for facilitating mangrove recovery after hurricanes on Caribbean islands
Mangrove ecosystems in the Caribbean are frequently exposed to hurricanes, leading to structural and regenerative change that elicit calls for recovery action. For those mangroves unaffected by human modifications, recovery can occur naturally. Indeed, observable natural recovery after hurricanes is the genesis of the “disturbance adaptation” classification for mangroves; while...

Potential for carbon and nitrogen sequestration by restoring tidal connectivity and enhancing soil surface elevations in denuded and degraded south Florida mangrove ecosystems Potential for carbon and nitrogen sequestration by restoring tidal connectivity and enhancing soil surface elevations in denuded and degraded south Florida mangrove ecosystems
Mangroves are tidally dependent wetlands that are influenced often by alterations in hydrology associated with coastal developments that impact their distribution, health, and function. Alteration in frequency, depth, duration, and seasonality of tidal inundation can lead to changes in forest condition, although these stress-adapted ecosystems may persist for many years before succumbing...

Belowground productivity varies by assessment technique, vegetation type, and nutrient availability in tidal freshwater forested wetlands transitioning to marsh Belowground productivity varies by assessment technique, vegetation type, and nutrient availability in tidal freshwater forested wetlands transitioning to marsh
Wetlands along upper estuaries are characterized by dynamic transitions between forested and herbaceous communities (marsh) as salinity, hydroperiod, and nutrients change. The importance of belowground net primary productivity (BNPP) associated with fine and coarse root growth also changes but remains the dominant component of overall productivity in these important blue carbon wetlands

Salinity, water level, and forest structure contribute to baldcypress (Taxodium distichum) rhizosphere and endosphere community structure Salinity, water level, and forest structure contribute to baldcypress (Taxodium distichum) rhizosphere and endosphere community structure
As rising sea levels alter coastal ecosystems, there is a pressing need to examine the effects of saltwater intrusion on coastal communities. Using 16S Illumina profiling, we characterized the communities of baldcypress tree (Taxodium distichum) root endosphere and rhizosphere soil bacteria. Our study utilized established sites along salinity and flooding gradients in the United States...

Structural impacts, carbon losses, and regeneration in mangrove wetlands after two hurricanes on St. John, U.S. Virgin Islands Structural impacts, carbon losses, and regeneration in mangrove wetlands after two hurricanes on St. John, U.S. Virgin Islands
Hurricanes Irma and Maria ravaged the mangroves of St. John, U.S. Virgin Islands, in 2017. Basal area losses were large (63–100%) and storm losses of carbon associated with aboveground biomass amounted to 11.9–43.5 Mg C/ha. Carbon biomass of dead standing trees increased 8.1–18.3 Mg C/ha among sites, and carbon in coarse woody debris on the forest floor increased 1.9–18.2 Mg C/ha, with...

Rapid peat development beneath created, maturing mangrove forests: Ecosystem changes across a 25-year chronosequence Rapid peat development beneath created, maturing mangrove forests: Ecosystem changes across a 25-year chronosequence
Mangrove forests are among the world’s most productive and carbon‐rich ecosystems. Despite growing understanding of factors controlling mangrove forest soil carbon stocks, there is a need to advance understanding of the speed of peat development beneath maturing mangrove forests— especially in created and restored mangrove forests that are intended to compensate for ecosystem functions...
