Vegetation and physical characteristics of Chesapeake Bay retreating Coastal Forests 2022-2024
This data set contains biomass and physical data across an upland forest to marsh transition. These measurements are taken at 5 sites around the Chesapeake and Delaware Bays. Data is collected at up to 5 ectones across the upland to marsh (High Marsh, Transition Zone, Low, Mid and High Forest). These ecotone definitions follow Smith et al. 2019, https://doi.org/10.6073/pasta/4524c22708628eb7f06d174edae89ff2).
Migratory shorebird habitat use, diet, and prey selection on mudflats in the Virginia barrier island and lagoon system, 2023-2024
Migratory shorebirds require access to heterogenous resources during migration. Understanding how shorebirds utilize different foraging substrates and food resources across the coastal landscape is important for informing conservation. We compared shorebird habitat use and invertebrate prey communities between barrier island and mudflat foraging substrates. We counted shorebirds and collected prey samples at random points on sand, peat, and mudflat substrates during spring migration (May 14 - June 2), 2023 - 2024. We opportunistically collected fecal samples on mudflats in our study area and used fecal DNA metabarcoding with 18S (invertebrates) and 23S (biofilm) primers to describe the diets of dunlin (Calidris alpina), red knots (Calidris canutus rufa) and semipalmated sandpipers (Calidris pusilla). We then used network null modeling to determine if our focal species were selectively consuming invertebrates on mudflats. Peat banks were the most heavily used intertidal substrate and mudflats supported similar shorebird abundances and species richness to sand. Dunlin and semipalmated sandpipers were more abundant on peat and mudflats, while red knots were more abundant on sand and peat. Invertebrate density was highest on peat banks and similar between mudflat and sand substrate, though mudflats supported a more diverse prey community. Amphipod crustaceans, blue mussels (Mytilus edulis), and polychaete worms were main prey consumed by all species on mudflats. Dunlin and semipalmated sandpipers fed primarily on crustaceans whereas red knots mainly fed on bivalves. All species consumed biofilm and a high proportion of diatoms were observed in fecal samples collected from semipalmated sandpipers. Red knots and dunlin selectively consumed bivalves on mudflats while semipalmated sandpipers showed no dietary preferences. Managing staging sites to preserve a diversity of intertidal habitats is critical for meeting the variable foraging requirements of migratory shorebirds.
Red knot occurrence, prey density, island morphology, and climate change in the Virginia Barrier Islands (2009-2023)
Global climate change is reshaping dynamic coastal ecosystems, with uncertain consequences for migratory shorebirds such as the federally threatened red knot (Calidris canutus rufa) that rely on coastal staging sites during migration. Understanding how sea-level rise and changing climate drivers affect red knot foraging ecology is critical for informing conservation and management at coastal staging sites. We integrated long-term biological, geomorphological, and climatological data to examine the direct and indirect pathways influencing red knots and their prey at intertidal foraging sites on the Virginia Barrier Islands during spring migration (May 21 - 28, 2009-2023). Using piecewise structural equation modeling, we tested hypothesized two causal networks linking 1) red knot occurrence and 2) densities of their main invertebrate prey to habitat characteristics, island morphology, geomorphic change, and climate drivers of ecosystem change. Red knots were indirectly affected by geomorphic change and climate drivers through bottom-up effects on invertebrate communities mediated by island morphology. Accelerated shoreline change narrowed islands, reducing invertebrate density and richness and indirectly decreasing red knot occurrence. Storms interacted with global climate oscillations to drive erosion or accretion of beaches, with variable effects on invertebrate density and red knot occurrence. Invertebrate responses were taxon-specific: shoreline change directly increased blue mussel density but indirectly reduced coquina clam and crustacean densities by narrowing island width, while storms impacts on crustacean density were mediated by beach width. Our findings suggest that accelerated ecosystem change under future climate scenarios may alter foraging conditions for red knots and other migratory shorebirds in the Virginia Barrier Islands, with broader implications for long-term population resilience.
Testing of a benthic incubation chamber design in a Virginia coastal bay, 2023, 2024, and 2025
Benthic incubation chambers enclose a known volume of water overlying a known area to measure water chemistry changes and are typically used to quantify the metabolic activity of benthic organisms or communities. Here, we report data from a series of tests validating a new benthic incubation chamber design. This data includes dissolved oxygen (DO) concentrations and temperatures recorded during three test deployments in South Bay, Virginia during August 2023 (T1_chamber_do_test_data), as well as data from light transmission tests. Light transmission tests included per wavelength transmission of PAR and ultraviolet radiation through the chamber wall (T2_wall_transmission_test) and lid (T3_lid_transmission_test), an in-situ PAR transmission comparison for two different sensor arrangements (side-mounted versus top-mounted) during July 2025 (T4_sensor_shading_test), and an in-situ comparison of natural ambient PAR versus PAR translated through a deployed chamber during March 2024 (T5_in_situ_light_test).
Hog Island VA Small-Mammal Trapping 1989-2020
This dataset contains information on long-term small mammal trapping on the Virginia Coast Reserve LTER. Four transects on Hog Island are included in the data, each of which was trapped at least twice each year, typically in the spring and autumn (note: Transect T2 was not trapped every year). Along each transect Sherman Live Traps were placed every 12.5 m along the transect, with an alternating offset of 2.5 m (to remove traps from the path running down the transect). This leaves a total inter-trap distance of 15 m. Traps were baited with peanut butter wrapped in waxed paper and were run sequentially for at least 3 nights in a row. Traps in areas that would experience tidal flooding were placed on styrofoam plastic platforms to provide flotation during high tides. Captured animals were individually tagged with numbered fingerling fish tags placed in the right ear, inspected for sex and sexual characteristics, weighed with a spring scale to the nearest gram and released at the point of capture.
Brownsville and Hog Island Surficial Well Data at the Virginia Coast Reserve 1990-2015
Data consist of conductivity, salinity, depth of measurement, depth of water table, temperature for each of 15 sites.
Tide Data for Hog Island (1991-), Redbank (1992-), Oyster (2007-)
Tide data from VCR/LTER tide stations. It is available as a single large comma-separated-value file (size >50MB) or as individual years. Zip files contain annually-segmented data in two forms. The file tideYY.dat contains the data for year YY in a column format. The file tideYY.csv contains the same data in a comma-delimited format. For several sites and time periods, water temperatures are also recorded. All dates and times are in Eastern Standard Time.
Long Term Mammal Data from Powdermill Biological Station 1979-1999
This is a 20-year record of small mammal trapping from the Powdermill Biological Station, Rector, PA 15677 collected by Joseph F. Merritt. It is included here as a comparative source of small mammal data.
Annual precipitation for the Virginia Coast Reserve 1837-2021
The long-term record of annual precipitation begins in 1837, the first year of systematic recording of precipitation amounts at Fort Monroe, Hampton Roads, VA. This remarkable record continued until 1985. Subsequent to 1985, precipitation records come from the NOAA meteorological station at the Norfolk International Airport.
