Data

This dataset provides the microsatellite genotypes for 466 flathead catfish collected in Pennslyvania rivers for an analysis of population genetic structuring of introduced popualtions. Also included is the spatial location of sample sites.

This dataset contains records of body sizes and critical thermal maximum test results of brook trout reared for 2 years under three different temperature regimes (+0 °C (the average daily water temperature of a nearby long-term study site), as well as +2 °C and +4 °C above that daily average), moved to a common colder temperature (~15 °C), and thermal tolerance measured using a critical...

Here we provide data used to report on changes in tidal marsh elevation in relation to our network of 20 fixed benchmarks located across a geographically broad network of coastal elevation monitoring stations with standard monitoring protocols. This dataset includes Surface Elevation Table (SET) measurements taken from 10 sites along the US Atlantic coast, ranging from Virginia to Maine...

These tabular data are the summarization of land use/land cover related variables within the Delaware River watershed at the 1:24,000 scale using the xstrm methodology. Variables being counted as land use/land cover related include all land use and land cover data. Outputs consist of tabular comma-separated values files (CSVs), and parquet formatted files for both the local catchment and...

These tabular data are the summarization of natural environment related variables within catchments of the Delaware River watershed at the 1:24,000 scale using the xstrm methodology. Variables being counted as natural environment related include soils/geology, lithology, elevation, slope, landform (geomorphon) and others. Outputs include tabular comma-separated values files (CSVs) and...

The survey was conducted to assess the distribution of terrapins in the Chesapeake Bay, based on evidence related to nesting. We conducted a survey of the beaches during the nesting season in the summer of 2002. We walked along the shoreline of over 1350 beach segments looking for evidence signifying the presence of terrapins based on nesting activity. These results represent a single...

This data product consists of raster digital data of population change and abundance estimates for 520 species of North American birds estimated from North American Breeding Bird Survey (BBS) data. Estimates of trend (yearly % change) from 1966-2022 and mean abundances for the interval 2018-2022 are spatially smoothed from data for each species collected on BBS routes. Metadata for the...

In this study, blue catfish were sampled from tidal reaches of the Chesapeake Bay in Maryland (Nanticoke River, Broad Creek, Marshyhope Creek, and Patuxent River) from March - October and at some sites, during specific times of the year. All fish were analyzed with histology to assess reproductive stage (immature, pre-spawn, and post-spawn) and plasma was collected for multiple endpoints...

The dataset contains observational records detailing collisions between boats and Florida manatees (Trichechus manatus latirostris). Data include boat speeds, collision locations, and manatee injury outcomes, and are intended for ecological analysis and conservation purposes.

This dataset provides estimates of residential septic tank densities at 12-digit Hydrologic Unit Code (HUC12), National Hydrography Dataset (NHD Plus version 2.1, 1:100k scale) catchment, and 2020 Census Block Group (version 2021) scale for the conterminous United States. Using United States Legacy Census data from the 1990s and the land use classification from the National Land Cover...

These data have been collected by the United States Geological Survey’s Northeast Amphibian Research and Monitoring Initiative (USGS NEARMI) scientists. We collected these data to examine if Bsal was introduced to a site where there was a known pet release in Western, Massachusetts.
