2025 Wetland Accretion Measurements from Smithsonian Environmental Research Center SMARTX Warming Plots
Sediment accretion measurements were made at the SMARTX warming experiment at the Smithsonian Environmental Research Center's Global Change Research Wetland. Feldspar marker horizons were established at the beginning of the experiment in 2016 in the warming plots, and were subsequently buried over time by wetland accretion of both organic and inorganic matter. These data include the...
Understanding mechanisms for Brook Trout persistence in warming streams: what stream temperatures do fish actually experience?
As stream temperatures increase, cold water adapted brook trout populations are projected to decline. However, there are mechanisms brook trout can use to persist in warming streams. Those mechanisms include acclimation, adaptation, and utilizing cold water refugia in streams where thermal heterogeneity is high. Using implanted temperature recording tags, this study examines individual...
Impact of Thiamine Deficiency on American eel swimming performance
The data were collected to examine the impact of thiamine deficiency and replacement with thiamine on the swimming ability of American eels.
Sediment core radioisotope measurements in coastal wetlands along the Chesapeake Bay
Data shows radioisotope measurements (Pb-210 and Cs-137) of sediment cores from four coastal wetlands along the Chesapeake Bay (one core from each site). Cores were sectioned every 1-2 cm depth.
Data supporting work to understand the impacts of 2.3.4.4b highly pathogenic H5N1 avian influenza virus infection on Snow Goose movement ecology
These data describe the prevalence of infection with and antibodies to clade 2.3.4.4b HP H5N1 in Snow Geese in the Central Valley of California, along with corresponding movement data. These data show differential outcomes of HPAI infection in this species.
Breeding shorebird surveys on the Arctic National Wildlife Refuge, Alaska (2019-2022)
This dataset contains results from long-term monitoring of breeding shorebirds on the Coastal Plain (1002 Area) of the Arctic National Wildlife Refuge, Alaska. Surveys were conducted during 2019–2022 using the Arctic PRISM (Program for Regional and International Shorebird Monitoring) protocol. The sampling design employed stratified random selection of 16-ha plots across four habitat...
Earthworm, Plant and Soil Pesticide Residue Concentrations resulting from a Treated Wheat Seed Mesocosm Exposure
The most common application of neonicotinoid insecticides in agriculture is through the treatment of seeds before planting. Commercially formulated seed treatments are often sold as mixtures of various pesticides, fungicides and other treatments (e.g., plant growth regulators), the effects of which in non-target organisms are not well understood. To address this data gap, we assessed the...
Physiological Effects of Pesticide-coated Wheat Seed Exposure to the Earthworm Lumbricus terrestris
The most common application of neonicotinoid insecticides in agriculture is through the treatment of seeds before planting. Commercially formulated seed treatments are often sold as mixtures of various pesticides, fungicides and other treatments (e.g., plant growth regulators), the effects of which on non-target organisms are not well understood. To address this data gap, we assessed the...
Data supporting a meta-analysis of avian influenza host dynamics
These data support analyses for a paired USGS manuscript that summarizes a meta-analysis of avian species and the role they play in the ecology of highly pathogenic avian influenza.
Stream temperature and fish community data upstream and downstream of an impoundment in Big Hunting Creek, Maryland
This Data Release provides stream temperature data (13 sites) and fish community data (3 sites) in Big Hunting Creek, Maryland. Data were collected during summer baseflow conditions in 2023. This product supports brook trout conservation and restoration research needs identified by Maryland Department of Natural Resources. We collected temperature data with Onset ProV2 water temperature...
Video observations of Common Terns usurping and brooding Least Tern chicks
These videos show a pair of common terns usurping a least tern nest with chicks. These data support a paired USGS authored manuscript.
Per- and Polyfluoroalkyl Substances in tree swallow gut contents
This data set is from a study examining the flow of per- and polyfluoroalkyl substances (PFAS) through food webs. The data are PFAS concentrations in gastrointestinal contents of tree swallows.
