Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Clothianidin concentrations in milkweed leaves that leads to prepupal mortality in monarch butterflies
A set of experiments was conducted to determine the dietary clothianidin exposures that cause prepupal mortality in the absence of other adverse effects. Monarch larvae were raised from hatch to pupae on clothianidin contaminated swamp milkweed plants. Larval growth, larval survival, and prepupal survival were monitored throughout the experiments in which the exposures ranged from 1.4 – 2,793.1 ng
Amplicon sequencing of pollen foraged by Bombus affinis for compositional analysis
This study generated genetic 'barcode' data using high-throughput sequencing to characterize pollen collected by the endangered rusty-patched bumblebee, Bombus affinis. Pollen samples were associated with a single Bombus affinis colony within a structure in Red Wing, Minnesota, USA, as previously described by Boone et al. (2022).

Digital data for the geologic map of Scoggins Dam, Henry Hagg Lake, and Scoggins Valley, Washington County, Oregon
Scoggins Dam in northwest Oregon lies within the Gales Creek fault zone (GCF), a northwest-striking system of active faults forming the boundary between the Coast Range and the Tualatin Valley about 25 km east of Portland, Oregon. Geologic mapping published in 2020 shows the dam to lie within a block-faulted releasing stepover between the right-lateral, NW-striking Scoggins Creek and Parsons Creek
Mercury concentrations in dragonfly larvae from the Willamette River Basin, 2023
Comma-separated values (.csv) file containing data related to mercury concentrations in dragonfly samples from the Willamette River Basin collected in 2023.
Conservation Efforts Database Spatial Reporting Units (SRUs)
This geospatial layer is a spatial index for the Conservation Efforts Database (CED, https://conservationefforts.org/), serving as a spatial framework for summary reports by area (a.k.a. polygon). In addition, this SRU (Sagebrush Reporting Unit) data is an option for data providers to provide spatial ambiguity to alleviate concerns of too much spatial detail representing private landowners’ effort
Per- and polyfluoroalkyl Substances in Select Domestic Wells in the Middle Chickahominy River Watershed, Virginia
Samples for per- and polyfluoroalkyl substances (PFAS) were collected from 10 domestic wells to assess the extent to which PFAS is coming from the groundwater aquifer or from another source within the home.
Specific objectives included:
Collect well construction information;
Collect samples for analysis of PFAS directly from the aquifer at domestic wells;
Collect samples for analysis of PFAS
Pseudogymnoascus destructans detections by US county 2007-2022
This data documents the results of sampling for the white-nose syndrome fungus, Pseudogymnoascus destructans (Pd) at the USGS National Wildlife Health Center between 2007-2022. Data are reported on the county level. Locations are accurate to county only. We used data collected at winter locations only (hibernaculum) for this data set.
Community-sourced lower Zanclean [early Pliocene] sea surface temperature (SST) data
This data set collects, from peer-reviewed research, values of sea surface temperature (SST) that occurred at select sites across the Earth during a brief period of the lower- Zanclean.
Glyphosate hormesis in the toxic alga Prymnesium parvum
The dataset associated with this metadata are included in two separate csv files, Trial 1 and Trial 2. Both .cvs files describe cell densities in different cultures measured at 3, 6, and 9 days of time at different glyphosate exposure concentrations.
Data and code release—Comparative toxicity of emulsifiable concentrate and suspension concentrate formulations of 2′,5-dichloro-4′-nitrosalicylanilide ethanolamine salt
Bayluscide, the 2-aminoethanol salt of niclosamide (2′, 5-dichloro-4′-nitrosalicylanilide), is a pesticide that is used in conjunction with TFM (4-Nitro-3-(trifluoromethyl)phenol) to treat streams tributary to the Great Lakes that are infested with invasive parasitic sea lamprey (Petromyzon marinus). The application TFM with 0.5 to 2.0 percent (%) Bayluscide can significantly reduce the amount of
Desert bighorn sheep (Ovis canadensis nelsoni) datasets from Grand Canyon National Park, 2010-2016
Tabular and raster data containing spatial capture recapture records for male and female bighorn sheep (Ovis canadensis nelsoni) in Grand Canyon National Park and surrounding landscape collected from 2010 to 2018 and associated tabular data files required for analysis of data with spatial capture connectivity models and raster data describing the ouput from SCR models. Associated tables and raster
