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...

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

A few studies have focused on avian gut virome variation in response to environmental stressors, but none have assessed virome in relation to chemically intensive crops, the production of which effects various aspects of avian health and fitness, and deleteriously alters available food resources. In this study we used shotgun metatranscriptomics (2 x 150bp; Illumina HiSeq 4000 with...

The North American Bird Banding Program is administered by the U.S. Geological Survey (USGS) Bird Banding Laboratory (BBL), Eastern Ecological Science Center at the Patuxent Research Refuge (EESC) and in Canada by the Bird Banding Office (BBO), Environment and Climate Change Canada (ECCC). This long-term dataset (1960-2025) consists of over 85 million bird banding, encounter and...

The frequency of cyanobacterial blooms appears to have increased globally in recent decades due to human induced eutrophication and climate change. Cyanobacterial blooms can produce several groups of toxins, among which microcystin-LR (MC-LR) is one of the most abundant. Effects of MC-LR on avian microbiome have not been studied and studies in laboratory murines are limited to...
