Tidal wetland gross primary production across the continental United States, 2000–2019 Tidal wetland gross primary production across the continental United States, 2000–2019
We mapped tidal wetland gross primary production (GPP) with unprecedented detail for multiple wetland types across the continental United States (CONUS) at 16‐day intervals for the years 2000–2019. To accomplish this task, we developed the spatially explicit Blue Carbon (BC) model, which combined tidal wetland cover and field‐based eddy covariance tower data into a single Bayesian...

Final Alabama Barrier Island restoration assessment report, appendix A: Data management plan Final Alabama Barrier Island restoration assessment report, appendix A: Data management plan
The Alabama Barrier Island Restoration Assessment project focused exclusively on Dauphin Island, a significant barrier island along the northern Gulf of Mexico. This restoration feasibility study effort required data collection and analysis of many data types (e.g., hydro, sediment, currents, etc.) through the project’s life cycle to assess restoration measures and their effects on the

Shifts in hatching date of American crocodile (Crocodylus acutus) in southern Florida Shifts in hatching date of American crocodile (Crocodylus acutus) in southern Florida
Globally temperature of marine environments is on the rise and temperature plays an important role in the life-history of reptiles. In this study, we examined the relationship between sea surface temperature and average date of hatching for American crocodiles (Crocodylus acutus) over a 37-year period at two nesting sites, Everglades National Park and Florida Power and Light Turkey Point...

Soil surface elevation dynamics in a mangrove-to-marsh ecotone characterized by vegetation shifts Soil surface elevation dynamics in a mangrove-to-marsh ecotone characterized by vegetation shifts
Mangrove forest encroachment into coastal marsh habitats has been described in subtropical regions worldwide in recent decades. To better understand how soil processes may influence vegetation change, we studied soil surface elevation change, accretion rates, and soil subsurface change across a coastal salinity gradient in Florida, USA, an area with documented mangrove encroachment into...

Trends of litter decomposition and soil organic matter stocks across forested swamp environments of the southeastern US Trends of litter decomposition and soil organic matter stocks across forested swamp environments of the southeastern US
A common idea in the discussion of soil carbon processes is that litter decomposition rates and soil carbon stocks are inversely related. To test this overall hypothesis, simultaneous studies were conducted of the relationship of environmental gradients to leaf and wood decomposition, buried cloth decomposition and percent soil organic matter in Taxodium distichum swamps across the...

Carrying capacity of a population diffusing in a heterogeneous environment Carrying capacity of a population diffusing in a heterogeneous environment
The carrying capacity of the environment for a population is one of the key concepts in ecology and it is incorporated in the growth term of reaction-diffusion equations describing populations in space. Analysis of reaction-diffusion models of populations in heterogeneous space have shown that, when the maximum growth rate and carrying capacity in a logistic growth function vary in space

Malaclemys terrapin (Diamondback terrapin) Lepadomorph epibionts Malaclemys terrapin (Diamondback terrapin) Lepadomorph epibionts
Diamondback terrapins (Malaclemys terrapin) are distributed along the Atlantic and Gulf of Mexico (GoM) coasts of the U.S.A. (Hart et al. 2014. Conserv. Genet. DOI 10.1007/s10592-014-0563-6). Under consideration for listing in Florida and proposed for Appendix II listing by the U.S. at CoP16 (CITES), terrapin populations are declining in many parts of their range due to drowning in crab...

Benthic infaunal communities of Baltimore and Norfolk Canyons Benthic infaunal communities of Baltimore and Norfolk Canyons
The imperative for finding, cataloging, and understanding continental margin diversity derives from the many key functions, goods and services provided by margin ecosystems and by an increasingly deleterious human footprint on our continental slopes (Levin and Dayton 2009). Progress in seafloor mapping technology and direct observation has revealed unexpected heterogeneity, with a mosaic...

Decision context as an essential component of population viability analysis Decision context as an essential component of population viability analysis
Population viability analysis (PVA) is a widely used tool that applies demographic data in simulation frameworks to assess extinction risk for species or populations. It is used in diverse conservation applications, including evaluating management effectiveness, relative risk of threats, and potential changes to protective status (Beissinger & McCullough, 2002), and can be a critical...

Mapping Phragmites australis live fractional cover in the lower Mississippi River Delta, Louisiana Mapping Phragmites australis live fractional cover in the lower Mississippi River Delta, Louisiana
In response to a co-occurring non-native scale infestation and Phragmites australis dieback in southeast Louisiana, normalized difference vegetation index (NDVI) satellite mapping was implemented to track P. australis condition in the lower Mississippi River Delta. While the NDVI mapping successfully documented relative condition changes, identification of cause required a quantitative...

Council monitoring and assessment program (CMAP) compilation of existing habitat and water quality monitoring and mapping assessments for the Gulf of Mexico Region Council monitoring and assessment program (CMAP) compilation of existing habitat and water quality monitoring and mapping assessments for the Gulf of Mexico Region
This report is a deliverable to the RESTORE Council for Task 7: Document the existing baseline habitat and water quality conditions prior to implementation of the restoration projects; these baseline conditions will serve as a basis for measuring change/progress after restoration. It is the second in a series of CMAP reports. The first report describes the process and development of the...

Envisioning a national invasive species information framework Envisioning a national invasive species information framework
With a view toward creating a national Early Detection and Rapid Response Program (EDRR) program, the United States National Invasive Species Council Management Plan for 2016–2018 calls for a series of assessments of federal EDRR capacities, including the evaluation of “relevant federal information systems to provide the data and other information necessary for risk analyses/horizon...
