Reproductive Parameters of Nesting <em>Caretta caretta</em> on Georgia's Barrier Islands
… understanding of the nesting populations on the barrier islands in Georgia is mainly limited to number of nests laid and number of females observed on select beaches. This method has proven problematic in estimating adult populations due to underestimating female nesting fecundity. Plasma steroid …

Piping plover habitat suitability on central Long Island, New York barrier islands
… (Charadrius me/odus) was examined on the central barrier islands of Long Island, N.Y. during the 1992 and 1993 breeding seasons. The estimated breeding populations were 79 pairs in 1992 and 82 pairs in 1993. Productivity was 1.08 chicks fledged per pair. The population appeared stable, but below …

Factors affecting Western Atlantic red knots (Calidris canutus rufa) and their prey during spring migration on Virginia's barrier islands
… canutus rufa, 'red knot') use Virginia's barrier islands as stopover habitat to regain the fat required to continue flights to breeding grounds. Because the red knot completes one of the longest avian migrations in the world and relies on variable prey resources at its stopover grounds, …

Invasion of Hurricane-Disturbed Scrub Communities on Barrier Islands in Mississippi: a Battle Between Native and Non-Native Ecosystem Engineers
… several hypotheses related to this idea within barrier island scrub communities dominated by Florida rosemary (Ceratiola ericoides Michx.). Hurricanes represent a major source of disturbance to coastal Florida rosemary communities, and individual rosemary shrubs in three populations recently …

Piping Plover (Charadrius melodus) habitat selection, survival, and migration on New York barrier islands following natural and engineered habitat changes
… migratory shorebird that nests on mainland and barrier island beaches on the Atlantic coast of North America. Its population decline was attributed to habitat loss, predation, coastal development, and disturbance. Hurricane Sandy reached the Northeast United States in October, 2012. The storm …

Density, Shell Use and Species Composition of Juvenile Fiddler Crabs (Uca Spp.) at Low and High Impact Salt Marshes on Georgia Barrier Islands
Coastal wetlands offer refuge for juveniles of many species, with protection often coming in the form of dense vegetation. Human impacts have led to a 67% loss of coastal wetlands worldwide in the past 300 years, thus decreasing available refuges. There are no studies that show what affect this has …

A System-Level Analysis of Migratory Shorebird Habitat Use, Diet, and the Influence of Climate-Driven Ecosystem Change in the Virginia Barrier Islands
… are threatened by climate change. The Virginia barrier island system supports over 100,000 shorebirds annually, including federally threatened red knots (Calidris canutus rufa) and other state and regional species of conservation concern such as dunlin (Calidris alpina) and semipalmated …

Shorebirds in a changing landscape: Assessing the top-down and bottom-up drivers of American oystercatcher (<i>Haematopus palliatus</i>) reproductive success in the Virginia barrier islands
… to global climate change. In the Virginia barrier islands, where American oystercatcher reproductive success has been historically high due to the widespread availability of undeveloped coastal habitat, declines in the average annual productivity rate of American oystercatchers since 2016 …

An environmental research laboratory for Back Bay National Wildlife Refuge
… understanding of the origin and order of coastal barrier islands continues to grow, designers are being forced to reevaluate their design strategies for the shore and near-shore areas. This project involves the design of an Environmental Research Laboratory on Back Bay, in the Back Bay National …

Morphological and Physiological Leaf Adaptations to Seasonal and Diurnal Abiotic Stress for Two Barrier Island Sand Dune Species
The coastal barrier island ecosystem provides protection to the coastline from storm and wave energy associated with extreme episodic storm events, such as hurricanes, tropical storms, and nor'easters. In addition, barrier islands produce, protect, and maintain inlets, bays, estuaries, wetlands, …

Complex retreat behavior in experimental barrier island response to base level rise
Barrier islands act as natural barriers between the ocean and the mainland. These islands create protected, low energy environments behind them that are important ecological and economic hubs. Barrier islands are naturally low-laying features and are susceptible to drowning from sea level rise. …

Model Development and Monte-Carlo Methods for the Simulation and Analysis of Coastal Impacts of Barrier Island Breach During Hurricanes
Barrier islands can protect the mainland from flooding during storms through reduction of storm surge and dissipation of storm generated wave energy. However, the protective capability is reduced when barrier islands breach and a direct hydrodynamic connection between the water bodies on both sides …

Coastal evolution on Earth and Titan
… the morphology of a coast in sandy environments (barrier islands) and detachment-limited environments (rocky coasts of Earth and possibly Titan). Barrier islands are dynamic and ephemeral, facing an uncertain future from climate change and anthropogenic redistribution of sediment. To evaluate …

Analysis of Virginia Barrier Island Shoreline Movement and Correlations to Sea Level, Wave Height Changes, and Teleconnection Patterns
<p>The Virginia barrier islands stretch from Assateague Island in the north to Fisherman’s Island in the south. This string of islands is subject to frequent North Atlantic extra-tropical storm and hurricane influence. In addition, sea level rise has the potential to cause continued shoreline loss …

Enhancing Coastal Community Resilience in North Carolina: Monitoring Erosion and Nature-based Solution Efficacy on a Fetch-limited Barrier Island
Fetch-limited barrier islands protect low-lying coastal communities like those in eastern North Carolina. They are natural barriers against powerful waves and storm impacts. However, coastal storms can subject barrier islands to elevated water levels and forceful waves, overwhelming their …

From Representative Period Selection to Process‐Based Sediment Dynamics
… tidal flats, channels, ebb-tidal deltas and barrier islands, in which tides, waves and wind jointly govern sediment transport. Despite its ecological and morphological significance, the region remains comparatively understudied, and its typical residual and storm-driven sediment pathways are …

Seagrass Carbon Standing Stock in the Northern Gulf of Mexico: The Role of Seagrass Beds in Mississippi as Potential Blue Carbon Sinks
… how persistent seagrass meadows surrounding barrier islands in the northcentral Gulf of Mexico contribute to long-term blue carbon standing stocks. Subaqueous sediment cores were collected to 1-m depth in seagrass meadows and bare sediment habitats surrounding Cat Island, Mississippi to …

Estuarine Dynamics as a Function of Barrier Island Transgression and Wetland Loss: Understanding the Transport and Exchange Processes
… (SLR) on estuarine dynamics in a transgressive barrier island setting. The field methods and numerical modeling in this study show that as barrier islands are converted to inner shoals, tidal exchange increases between the estuary and coastal ocean. If marshes are unable to accrete at a pace …

Subsurface controls on mainland marsh shoreline response during barrier island transgressive submergence
… have sought to understand the response of barrier islands and their attendant marshes to sea level rise. The Mississippi River delta plain, specifically the Chandeleur Islands and associated interior wetlands in eastern Louisiana, serves as an excellent natural laboratory for studying these …

Impacts of Human Disturbance on the Behavior of Sanderlings on the Georgia Coast
… humans. The study was conducted on two Georgia barrier islands with varying levels of human disturbances, Tybee Island and Sapelo Island. I found that Sanderlings on a high-disturbance beach had lower foraging success than those on a low-disturbance beach. Across sites, Sanderling foraging …
