Data

This metadata record describes a series of data sets of climate and land-use/land-cover features (provided in parquet file format) linked to NHDPlus Version 2.1’s (NHDPlusV2) stream segments, their associated catchments and their upstream watersheds within selected regions in the conterminous United States. All data can be linked to NHDPlusV2 using the COMID field in these tables and the...

This study examined effects of the brominated flame retardant hexabromocyclododecane (HBCD) on the avian endocrine system. Japanese quail (Coturnix japonica) were exposed to multiple doses of HBCD over multiple generations through feed and by maternal deposition into the egg. Liver transcriptomes were examined to identify genes and pathways directly affected by HBCD to better understand...

Natural resource managers worldwide grapple with protecting aquatic environments and species in the face of intensifying land use and climatic changes. The hierarchical landscape theory suggests that a species distribution is impacted by multiple series of environmental factors affecting the species at multiple spatial resolutions. For a species to inhabit an area, it must pass through...

The Ecology Section at the USGS Conte Laboratory has studied fish in the West Brook since 1997. The goal is to understand the strength and direction of drivers on fish growth, movement, reproduction and survival in the wild. We hope to provide a comprehensive understanding of fish population dynamics for this stream network and ultimately individual fitness (natural selection and...

Mark-recapture records of salamanders in the genus Desmognathus within stream habitat at Shenandoah National Park, Virginia from 2007-2013

The Grand Calumet River flows through northwestern Indiana and was designated an EPA Area of Concern (AOC) in 1987. There are multiple legacy pollutants in the river including but not limited to heavy metals and PCBs. To investigate potential causes and patterns of eutrophication in the river, water samples were collected for 16S rRNA microbial and eukaryotic 18S rRNA amplicon sequencing...

These data were collected using distance sampling methods (point counts) and visual assessment of land cover and habitat at randomly selected locations in the Western Gulf Coastal Plain ecoregion of Texas and Louisiana in April-May 2017-2019.

The purpose of this study was to collect and analyze non-invasive DNA specimens from the endangered island marble butterfly (Euchloe ausonides insulanus) to assess population structure, identify adaptive potential, facilitate captive propagation, and support translocation planning. We used DNA extracted from meconium, exuviae, and natural mortalities to generate and test thirteen new

Plasma from adult smallmouth bass was analyzed for 13 per- and polyfluoroalkyl compounds at 11 sites for a spatial comparison. At four sites a temporal comparison was made over a three year period (2017-2019). At two sites tissue comparisons were made using plasma, whole blood, liver, gonad and muscle. Compounds detected at least once are included in the dataset. For all fish collection...

This data release includes the raw data and code used in Castro-Santos et al. (2024): Sprinting performance and behavior of adult shortnose sturgeon (Acipenser brevirostrum). Notably, the code includes several processes used to differentiate among attempts, quantify attempt rate, distance traversed, and endurance of shortnose sturgeon ascending a telemetered flume. The code can be...

In this dataset, there are eight text files that provide the raw fish behavior telemetry data and an excel sheet that provides the processed velocity data.

Raster data shows landscape scale trajectories of change as four potential scenarios based on Normalized Difference Vegetation Index (NDVI) trends and standard deviation trends using full time series (Scenarios_All_FULL_TS.tif) as well as time series up to LandTrendr breakpoint if detected (Scenarios_All_LT_TS.tif). Time series analysis for trend use Landsat surface reflectance imagery...
