Captive wild ducks in the research colony at the USGS Eastern Ecological Science Center, Laurel, Maryland USA frequently contract Candida infections on the upper and lower bills. Various standard treatments were attempted with mixed success. Several of the Surf Scoters, especially, suffered extreme erosions of the bill leading to euthanasia prior to using this new treatment. For the past...

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 546 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

Dataset includes the number of shortnose sturgeon that were detected via acoustic telemetry and side-scan sonar in the Hudson River on a series of survey dates from 2021 to 2023.

Environmental DNA (eDNA) metabarcoding may have utility in biodiversity surveys of marine environments, particularly for small, rare, or cryptic taxa that are more difficult to study using traditional methods (e.g., trawling and visual surveys). For this study, we used an eDNA metabarcoding approach to characterize biodiversity in the above-seafloor water column across three West Coast...

We compared pollinator diversity derived from environmental DNA (eDNA) extracted from flowers and DNA extracted from pulverized bulk samples of insects collected from vane traps deployed at the same sites. We used three metabarcoding primers, two of which target arthropods generally (COI-Jusino and 16S-Marquina) and one that targets bumblebees (Bombus spp., COI-Milam). Across methods, we...

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...
