Population genetic data for flathead catfish from the Susquehanna and Delaware River basins in Pennsylvania and Maryland, USA

This dataset includes microsatellite genotypes for 137 flathead catfish from the Susquehanna River and Delaware River basins in Pennslyvania and Maryland, USA. Each individual was genotyped at 13 loci. Additional information about sex, capture date, and size are also provided for most individuals.

Population genetic data for wild Brook Trout (Salvelinus fontinalis) from the Midwestern United States and selected domestic strains

This dataset includes microsatellite genotypes for 8,454 brook trout from 188 wild Midwestern populations and 26 hatchery strains of both Midwest and eastern (Atlantic seaboard) origin. Each individual was genotyped at either 5 or 7 loci.

Summary and synthesis of 15 years of the Amphibian Vital Sign monitoring in the National Capital Region Inventory and Monitoring Network

This data set is comprised of four files related to the counts of amphibian species in the National Capital Region of the United States. Data was obtained from surveys of both lentic (wetland) and lotic (stream) sites within national parks.

Changes in Organic Carbon Source and Storage with Sea Level Rise-Induced Transgression in a Chesapeake Bay Marsh

This data set includes a variety of bulk organic carbon, lignin-phenol biomarker, and sedimentation rate data from a set of sites in the Blackwater Marsh in Chesapeake Bay. At each site, a short core was taken, and all data is organized according to depth below the marsh surface. Data includes: Bulk %OC, bulk %N, atomic carbon:nitrogen ratios, stable carbon isotopes (d13C) Lignin-phenol biomarker

Genotypes of Atlantic Sturgeon collected from Canada to Georgia used in the development of a genetic baseline

This dataset includes microsatellite genotypes for 2510 Atlantic sturgeon from 18 different populations distributed from Canada to Georgia. Each individual was genotyped at 12 loci. Additional information about sex, capture date, and size are also provided.

Poplar Island Digitizing

In order to allow for a comparison across years we visually digitized landcover of Poplar Island from a single image per year at a 1:1000 spatial extent with a minimum mapping unit of 300 square meters (no minimum dimensions aside from area). Images used to assign landcover were provided by the U.S. Army Corps of Engineers and were captured between July and October of their respective years. All i

Fish survey data for Asaph, Straight, Canada and Baldwin Runs, Tioga County, PA, 2012-2017

Fish survey data for four stream in Tioga County Pennsylvania from 2012-2017. Community data based on 2-3 backpack electrofishing passes with individual lengths and weights.

The North American Breeding Bird Survey, Analysis Results 1966 - 2019

This data product consists of a database of population change and abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented for 548 species of birds in 4 spreadsheets containing trend estimates and annual indices for 2 time periods. Estimates are derived for each species using the 1 of 4 alternative models, and a cross-validatio

Testing transmitter types, harness types, and harness materials for attachment of radio transmitters onto avian chicks

In an effort to facilitate research into the period between fledging and first breeding of juvenile terns we examined the impact of various combinations of harness types (backpack, leg-loop, and 3D printed harnesses), harness materials (Conrad-Jarvis automotive ribbon, Stretch Magic elastic thread, and Teflon ribbon), and transmitter types (CTT LifeTag and Lotek Nanotag) on a surrogate for juvenil

Annotated fish imagery data for individual and species recognition with deep learning

We provide annotated fish imagery data for use in deep learning models (e.g., convolutional neural networks) for individual and species recognition. For individual recognition models, the dataset consists of annotated .json files of individual brook trout imagery collected at the Eastern Ecological Science Center's Experimental Stream Laboratory. For species recognition models, the dataset consist

Hepatic Transcriptome of Japanese quail (Coturnix japonica) Exposed to 17B.-Trenbolone

The files in this data release are RNA seq datafiles from a study that examined the effects of the synthetic anabolic steroid 17B. hydroxyestra 4,9,11 trien-3-one, trenbolone (17B.T - CAS 10161-33-8), a common contaminant of wastes from confined animal feeding operations (CAFOs). Japanese quail (Coturnix japonica) were exposed in the egg and through feed to multiple doses of 17βT and liver transcr

Morphometric, Age, Visible Abnormalities, Skin and Liver Neoplasms, and Stable Isotopes in White Sucker Collected in the St. Louis River and Estuary, Minnesota/Wisconsin, 2011-2015

The dataset provides length, weight, age, observations of visible external abnormalities, liver and skin histopathology and stable isotopes of white sucker captured within the St. Louis river and associated bays.
