Health assessment of invasive northern snakehead in the Potomac River drainage, 2006 - 2017.

Data described herein was collected by USGS personnel and the project funded by USGS. Northern snakehead specimens were collected from the Potomac River and its tributaries by regional natural resource management agencies in the course of their field investigations working with this priority invasive aquatic species. Specimens were provided to USGS for the purpose of conducting health related asse

Field data to support speciation with gene flow in a narrow endemic West Virginia cave salamander (Gyrinophilus subterraneus)

This data set is comprised of 4 files consisting of field observations, morphological measurements, and water quality measurements relevant to a publication on the classification and population status of the WV Spring salamander, Gyrinophilius subterraneus.

Fish community and species distribution predictions for streams and rivers of the Chesapeake Bay Watershed

This data release contains predictions of selected fish community metrics and fish species occurrence using Random Forest models with landscape data for inland reaches across the Chesapeake Bay Watershed (CBW). Predictions were made at four time intervals (2001, 2006, 2011, and 2016) according to changes in landcover using the National Land Cover Database (NLCD). The fish sampling data used to com

Environmental and Vegetation Data from Marsh-Forest Transgression Experiment at Blackwater National Wildlife Refuge, MD, USA

We conducted a field experiment at the Moneystump Swamp in the Blackwater National Wildlife Refuge in Dorchester, MD, USA to simulate a natural forest disturbance event (e.g., storm-induced flooding) by inducing the death of established trees (coastal loblolly pine, Pinus taeda) at the marsh-upland forest ecotone. There were three treatment components: Cut- where the trees were cut and removed, Gi

Biological variables and liver and testes transcript abundance from smallmouth bass sampled in the Lake Erie drainage, Pennsylvania (2016)

In 2016, smallmouth bass were collected from three sites in the Lake Erie drainage in Erie County, Pennsylvania and an out-of-basin site in the Allegheny River drainage in order to assess reproductive health and identify endocrine disruption responses. Pieces of liver and gonad were taken in Z-Fix and RNALater for histology and transcript abundance analysis. A landscape analysis was conducted for

Novel genetic resources for Clubshell freshwater mussels (Pleurobema clava, P. oviforme) for enhanced conservation

Here we provide public access to two mitochondrial DNA sequence alignments, multi-locus microsatellite DNA genotypes, morphometric measurements and details on all specimens utilized in Morrison et al., 2021 (In press).

Modeled estimates of altered hydrologic metrics for all NHDPlus v21 reaches in the Chesapeake Bay watershed

Data are modeled estimates of flow status (inclined, diminished, or indeterminant) for 12 published hydrologic metrics (HMs) that characterize main components of flow regimes (duration, frequency, magnitude, timing, and rate of change). Model estimates came from random forest models independently built for each HM that predict flow status category using drainage area and previously summarized upst

Decision-Support Framework for Linking Regional-Scale Management Actions to Continental-Scale Conservation of Wide-Ranging Species

This data release presents the data, JAGS models, and R code used to manipulate data and to produce results and figures presented in the USGS Open File Report, "Decision-Support Framework for Linking Regional-Scale Management Actions to Continental-Scale Conservation of Wide-Ranging Species", (https://doi.org/10.5066/P93YTR3X).

Physiological and Endocrine Responses of Hatchling American Kestrels (Falco sparverius) following Embryonic Exposure to Technical Short-Chain Chlorinated Paraffins (C10-13)

- Observations of test subjects and hatching data - Body weight, organ/tissue weights - Biomarker data (oxidative stress indicators, oxidative DNA damage, thyroid hormones, histological findings) in various tissues - Chemical residues in tissues

Spatial Hydro-Ecological Decision System Summarized Designing Sustainable Landscapes and National Land Cover Database 2001 - 2016 Data for SHEDS Region 2

This data release is a summarization of the US Geological Survey National Land Cover Database (NLCD) 2001, 2004, 2006, 2008, 2011, 2013 and 2016 Land Cover datasets and the Landscape Ecology Lab at the University of Massachusetts Designing Sustainable Landscapes (DSL) datasets within the USGS Spatial Hydro-Ecological Decision System (SHEDS) framework. The output is a series of tables consisting of

North American Bird Banding Program Dataset 1960-2021 retrieved 2021-07-25

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
