Pleistocene Terraces of The Atlantic Coastal Plain
<p>Pleistocene terraces on the Atlantic Coastal Plain have been recognized since the late 1800's, and from four to seven terraces have been described throughout Maryland, Virginia, North Carolina, South Carolina, and Florida. These terraces are now named Brandywine, Coharie, Sunderland, Wicomico, …

Nutrient Foraging in Ten Southeast Coastal Plain Plant Species
… plants tested are native to the South Carolina coastal plain. Morphological responses of the root system (scale, precision and discrimination) and overall plant response (sensitivity) to increasing nutrient heterogeneity were tested. Ten individuals of each species were placed into four …

Ecology of Two Rare Amphibians of the Gulf Coastal Plain
… purported to be driving the decline. The Gulf Coastal Plain of Florida has a high degree of endemism and rarity and the biodiversity in the region includes a diverse suite of amphibian species. Degradation of habitat has been considered by many to be a major part of amphibian declines, however …

Soil mineralogy of an upper coastal plain landscape in Virginia
… for its proposed operation in the Upper Coastal Plain of Virginia due to the high clay content of the deposit. The original intent of this study was to identify the mineralogy present in the proposed mining area and to determine similarities and differences among sampled pedons. …

Applicability of Stormwater Best Management Practices in the Virginia Coastal Plain
… practices (BMPs) to meet regulatory standards. Coastal Virginia is characterized by flat terrain, shallow water tables, and low permeable soils that may limit the application of BMPs as recommended by state regulations. Soil morphological features are often used to estimate the seasonal high …

An Analysis of Palustrine Mitigation Wetlands in the Virginia Coastal Plain
… wetland pairs located in the Virginia Coastal Plain. Hydrologic regimes of mitigation areas, when compared to reference areas, generally showed larger differentials between seasonal high and low watertables. Mitigation areas, dominated by herbaceous vegetation, tended to be lower in C …

Response of corn to manganese application on Atlantic coastal plain soils
… conducted in five field experiments on Atlantic Coastal Plain soils. The mean increase in corn grain yield in the band studies on three soils was 960 kg ha⁻¹. Corn grain yields were not increased in the broadcast Mn studies on Slagle and Dragston fine sandy loams. Manganese uptake from the Slagle …

Taxonomic and Phylogenetic Diversity of Pitcher Plant Bogs in Georgia's Coastal Plain
… and phylogenetic diversity vary among Georgia’s Coastal Plain pitcher plant bogs? Three bogs residing in three different level IV ecoregions (Sea Island Flatwoods, Tifton Uplands, and Atlantic Southern Loam Plains) were chosen for floristic study and tissue samples taken for DNA barcode …

Tillage effects on leaching and persistence of pesticides in coastal plain soil
… was evaluated in a field study in the Coastal Plain region of Virginia. Field data were also used to validate pesticide transport models, GLEAMS and PRZM. The study was conducted on two 18x27 m plots located in a field that was in the second year of a two-year no-till wheat-beaDs-com …

Dynamic systems analysis of fossil dinoflagellates from the Atlantic Coastal Plain, USA
Dynamic Systems modeling suggests that complex coastal dinoflagellate biosystems can be modeled using environmental parameters such as temperature, salinity, and bulk nutrient levels. The former Salisbury Embayment of northern Virginia and Maryland is modeled here, using STELLA I and FORTRAN models …

Ecosystem metabolism in coastal plain streams of southeast Louisiana : environmental and watershed effects
… such as flooding on ecosystem metabolism in coastal plain streams of southeast Louisiana are described. These systems behave similarly to previous studies and provide more evidence that the use of ecosystem metabolism as a metric for stream health is beneficial. Recommendations for future …

Soil Microbial Community Distributions And Disease Suppressiveness In The Coastal Plain Of Georgia
… communities of three vegetation types in the coastal plain of Georgia: 1. crop land actively in use for agricultural production, 2. transitional grassland in early stages of secondary succession, and 3. pristine unmanaged forest land. Microbial species diversity and quantities of microbial DNA …

Impact of nutrient heterogeneity on plant response and competition in Coastal plain species
Relationships between nutrient heterogeneity, root foraging behavior and short-term competitive interactions were investigated for six species native to southeastern USA. Monoculture, two- and six-species garden plots were established and fertilized to create spatially homogeneous or heterogeneous …

Life History Divergence & Tidal Salt Marsh Adaptations of the Coastal Plain Swamp Sparrow
… season length, salinity and tidal flow of the coastal marshes relative to inland wetlands has resulted in a number of adaptations among coastal sparrows due to natural selection, sexual selection, and phenotypic plasticity. Specifically I examine the habitat preferences of the coastal plain …
