Modern Foraminiferal Bio-facies within a Transgressive Saline Influenced Deltaic Headland, South-Central Louisiana
… of environmental variables known to influence marsh foraminifers in other coastal regions refined marsh foraminiferal biofacies of the Mississippi delta region. Elevation, pore water salinity, total carbon, and mean grain size were compared with foraminiferal distributions in a transgressive …

Addressing the land loss-fish production paradox
Saltmarsh loss is occurring at high rates in Louisiana (LA), but understanding the impacts that marsh degradation has had on historical abundance of estuarine nekton in Barataria Bay, LA is lacking. I first examined the differences between fishery independent and fishery dependent data as indices …

Salt marsh substrate composition and responses to applied stress
Salt marshes provide a variety of ecosystem services, including habitat provision, pollutant storage and attenuation of waves and currents. As such, understanding the resistance of the marsh sedimentary platform to erosion is important, particularly as marsh edge erosion is common on many shores. …

The ecology of two estuarine-dependent tonguefishes, the blackcheek tonguefish (Symphurus plagiusa) and the offshore tonguefish (S. civitatium), in coastal Louisiana
… Current management plans designed to stabilize marsh elevations, such as freshwater diversions, may also influence the distribution and abundance of estuarine-dependent nekton. Given the importance of nursery function of inshore estuaries in coastal Louisiana, it is of interest to explore the …

Birds on Modified Wetlands in Eastern South Dakota
… the red-winged blackbird (Agelaius phoeniceus), marsh wren (Cistothorus palustris), and song sparrow (Melospiza melodia). Analysis of variance was used to test between treatment (modified and natural plots on the wetlands) differences for the dependent variables: density, bird species diversity, …

Archaeological Survey and Limited Testing at the Lincoln Trail Site (9bn17), Bryan County, Georgia
… scatter and complex of shell middens in a marsh-edge environment, yet little was known of the site’s nature and no subsurface survey was conducted. 9BN17 was selected as a case study for a broad research query to identify the structure of mainland Irene phase polities and the role that this …

Linkages between Marsh Fragmentation, Prey Availability, and Blue Crab (<i>Callinectes sapidus</i>) Abundance and Mortality
<p>Coastal marshes are important nursery habitats for many commercially important invertebrate species, yet these marshes are being lost worldwide at an unprecedented rate due to subsidence, erosion, climate change, and human activity. As marsh is lost, it creates the opportunity for submerged …

Identifying Erosional Trends of Upper Galveston Bay Salt Marshes from 2004-2018 High Resolution Imagery: A GIS and Remote Sensing Analysis
… it is possible to record these changes in the marsh as vector features for future use in presentations or modelling. In a place like Galveston Bay, Texas, coastal salt marshes and residential or urban centers coexisting near one another are commonplace, so tracking the health of the marsh based …
