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

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

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

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

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

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.

Fish collection data for surveys made at 5 localities in Flat Creek, Dawson County GA, on 6 dates that spanned a 4 to 18.5-month period following a catastrophic fish kill caused by a chemical spill near the headwater origin on Flat Creek. The data are: locality descriptions, water depth and velocity measurements made during fish sampling, and tabulated numbers and range in body length of individua

This dataset includes all North American Breeding Bird Survey data collected in Mexico between 2008-2018. These data were used as the basis for all analyses discussed in an associated publication: The North American Breeding Bird Survey in Mexico, 2008-2018 - A Status Report; https:doi.org/10.3133/cir1479. The records include avian point count data for all reported taxa (species, races, and unid

The North American Bird Banding Program is directed in the United States 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). The respective banding offices have similar functions and policies and use the same bands, r

Archived plasma from fish health monitoring sites within the Chesapeake Bay watershed was analyzed for 13 perfluoroalkyl compounds. Smallmouth bass were collected from two sites in the Potomac River drainage (Antietam Creek, Maryland and South Branch Potomac, West Virginia) and two in the Susquehanna River drainage (West Branch Mahantango Creek, Pennsylvania and Pine Creek, Pennsylvania). Site and

Water levels in meters from four wells in Moneystump marsh at Blackwater National Wildlife Refuge, MD. Two wells are located in the upland forest; one well is located in the marsh-forest transition zone (ecotone); and one well is located in the marsh. Water depth of the adjacent creek is reported in meters. Data covers the time span from November 11 2016 - November 11 2017. Pressure transducer dat
