Data

This dataset includes stream and species data collected in headwater streams on public lands throughout the eastern United States. Data were collected to inform updated species range maps and provide data for large-scale modeling of species ranges using multiple data types. All salamander species encountered are included in the dataset.

The dataset contains observational records of encounters of meadow voles (Microtus pennsylvanicus) trapped at Eastern Ecological Science Center (formerly Patuxent Wildlife Research Center) in Laurel, Maryland, USA. Animals were trapped using Sherman traps from 23 September 1991 to 24 August 1993. Data collected included id, date, age, sex, weight, location and reproductive status.

In this dataset, there are six csv files that provide the raw fish behavior telemetry data and a single csv file that provides the processed velocity data.

The 1966-2024 North American Breeding Bird Survey (BBS) dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings). These data are collected annually during the breeding season, primarily in June, along thousands of randomly established roadside survey routes in the United States and Canada. Routes are roughly...

This study assessed site-specific differences in PFAS in fish from Ashumet Pond (2020 & 2022), Sudbury River (2023), and Great Herring Pond (reference site; 2022) in Massachusetts. Largemouth bass were collected from all sites and banded killifish were collected from Ashumet Pond only. Health assessments were performed and included histology of the liver, spleen, kidneys, gonad, and any

Serum samples were collected from an American Kestrel colony at the U.S. Geological Survey (USGS) Eastern Ecological Science Center and analyzed for per- and polyfluoroalkyl substances (PFAS). The sampling effort was undertaken as part of a Strategic Environmental Research and Development Program (SERDP) funded project (ER22-3388) to study the exposure effect of PFAS on immunomodulation...

This study investigates the feeding and trophic ecology of invasive Blue Catfish (Ictalurus furcatus) in the Nanticoke River watershed on the Chesapeake Bay’s Eastern Shore (Maryland, U.S.A). From a total of 1,032 stomach samples collected, a subset of 88 was analyzed using 18S and COI metabarcoding primers to enhance taxonomic resolution of prey items. USGS-generated genetic reference...

Clade 2.3.4.4b Eurasian-origin H5N1 entered North America in late 2021 and spread across the continent. While studies have characterized the antibody response mounted by dabbling ducks following exposure, little data is available for diving ducks. This study sought to identify influenza A virus (IAV) infection and antibodies in Lesser and Greater Scaup captured in Maryland, Illinois, and...

The data set consists of eastern box turtle encounters made at Patuxent Refuge from 2019-2025 as part of organized field surveys on Central Tract.

Nest number, description of nest structure and location, longitude, latitude, dates of observations, presence of adults, eggs, nestlings, outcome of reproductive effort, number of young fledged, body weight and culmen length of some nestlings, and osprey nest platforms occupied by Canada geese.

The data are a curated set of 200k records of bees, both native and introduced, that were collected from 2002 – Present throughout the state of Maryland and the District of Columbia. Collection methods, habitats, and duration of studies ranged depending on project.

Stream-like habitats in abandoned mine areas of New River Gorge National Park and Preserve were surveyed for stream salamanders in fall 2024. Methods included visual encounter surveys of transects up to 25m within stream-like mine water discharges in the Nuttallburg, Fayette Station, Hawks Nest Connector, and New River Gorge Bridge areas of the park. All stream salamander species...
