Atlantic ghost crab (Ocypode quadrata) burrow counts at shorebird nests and randomly available sites on Metompkin Island, Virginia, 2022
Atlantic ghost crabs (Ocypode quadrata) are predators of beach-nesting shorebirds, their nests, and their chicks on the United States' Atlantic and Gulf coasts. Ghost crabs may also disturb birds, altering their foraging, habitat use, or nest and brood attendance patterns. Shorebird conservation strategies often involve predator and disturbance management to improve reproductive success, but efforts rarely target ghost crabs. Despite the threat to shorebird reproductive success, ghost crabs are a poorly understood part of the beach ecosystem and additional knowledge about ghost crab habitat selection is needed to inform shorebird conservation. We monitored ghost crab activity, defined as burrow abundance, throughout the shorebird breeding season on Metompkin Island, Virginia, an important breeding site for piping plovers (Charadrius melodus) and American oystercatchers (Haematopus palliatus). We counted burrows at shorebird nests and random points throughout the shorebird breeding season and tested whether ghost crab activity was greater at shorebird nest sites than random sites. We observed burrows at all nest sites in our study area (n = 63 nests), but found fewer burrows at nest sites than random sites. Ghost crabs may avoid shorebird nest sites due to aggressive defensive behaviors from incubating adults or differences in microhabitat characteristics selected by shorebirds versus ghost crabs. We also tested the effects of date, air temperature, habitat type, and shell cover on the abundance of ghost crab burrows. We found that while burrows were present across the barrier island landscape, there were more burrows in sandy habitats with sparse to little shell cover and in and behind the dunes relative to the beach and beach-front berm. Ghost crab activity increased later in the shorebird breeding season and as air temperature increased. Understanding when and where ghost crabs are most likely to be active in the landscape can aid decision-making to benefit imperi
Historical shorelines for the Atlantic barrier islands of Virginia south of Chincoteague Inlet, 1949-2006
Historical shorelines for the Virginia barrier islands from Fishermans Island to Wallops Island were compiled from various remote sensing and ground-based sources. The COAST dataset (Dolan et al. 1978, Dolan et al. 1990) tabulated shoreline position based on historic aerial orthophotographs at transects spaced 50 meters apart located along the mid-Atlantic coast of the United States (South Carolina to New Jersey); only data for the Virginia barrier islands (1949-1988) are presented here. COASTS data are supplemented with more recent shoreline data digitized from aerial imagery (USGS 1994 and VGIN 2002) and collected with GPS (Fenster 2006). Baselines and transects used both to reconstruct the COASTS data and to produce shoreline positions and calculate shoreline rates of change using DSAS are also included. Note: there are some unresolved georeferencing issues that cause inconsistencies in the shorelines from different base data frames. Data from different data frames should be integrated with caution. Future versions of this dataset will resolve these issues.
Atlantic sand fiddler differences in antimony, running velocity, and behavior, Sapelo Island, Georgia: 2021
Running velocities and behavior assay data of 42 crabs (21 male and 21 female) from Sapelo Island, Georgia. Each crab had three run trials and four for the behavior assay. Crabs were run on a 1m track and behavior assays timed how long it took for crabs to reemerge from burrows. These data were used to determine major influences on crab behavior.
Shorelines and island boundaries for the Atlantic barrier islands of Virginia, 1851-2017
This dataset provides a shorelines (VBI-allshores.zip) and set of area polygons (VBI-allislands.zip) delineated from historical NOS t-sheet (1851-1962) and USGS satellite imagery (1994-2017) spanning the barrier islands of the Eastern Shore of Virginia in multiple GIS data layers. The VBI-allshores dataset provides a comprehensive set of historical NOS t-sheet (1851-1979) and satellite imagery (1980-2017) shorelines spanning the islands south of Assateague along the Virginia Eastern Shore in a single GIS data layer. This shoreline dataset compliments and overlaps other VCRLTER shoreline datasets for the Virginia barrier islands that contain historical shorelines derived from a combination of sources, including photointerpretation of aerial photos, satellite imagery, and LiDAR assessments (from USGS, NOAA, VITA-VGIN-VBMP, and others). The VBI-islands dataset provides a set of area polygons delineated from historical NOS t-sheet (1851-1962) and USGS satellite imagery (1994-2017) spanning the barrier islands of the Eastern Shore of Virginia in multiple GIS data layers.
