Data

This study generated genetic 'metabarcode' data using high-throughput sequencing to characterize pollen foraging behavior of the endangered rusty-patched bumblebee, Bombus affinis. Pollen samples were collected primarily from forest meadow habitats in the Appalachian piedmont of the eastern United States, specifically within the states of Virginia and West Virginia. Three additional...

This study generated genetic 'metabarcode' data using high-throughput sequencing to characterize pollen foraging behavior of pollinating bee species on managed field habitat within units of the National Park Service. Specimens were collected within parks of the National Capital Region from 2021-2023 and subsequently identified to species or genus. DNA was then extracted from specimens...

Moderate-resolution (30 m) national map products have limited capacity to represent fine-scale, heterogeneous urban forms and processes, yet systematic improvements from incorporating higher resolution predictor data remain rare. In this study, we applied random forest models to high-resolution land cover data for 71 U.S. urban areas, moderate-resolution National Land Cover Database...

Cone Penetration Test (CPT) data collected by the U.S. Geological Survey since 1978 are compiled and provided as a uniformly formatted set of comma separated value (.csv) files. This dataset includes 1822 CPT soundings from 14 U.S. States. Provided CPT data are a set of three column comma separated value (.csv) files containing depth (meters), tip resistance (̨MPa), and sleeve resistance...

SUMMARY This Data Release contains an updated version of the San Andreas catalog of low-frequency earthquakes (LFEs) originally published here: Shelly, D. R. (2017), A 15 year catalog of more than 1 million low-frequency earthquakes: Tracking tremor and slip along the deep San Andreas Fault, J. Geophys. Res. Solid Earth, 122, 3739–3753, doi:10.1002/2017JB014047. This updated catalog...

This dataset contains the information used to perform ecological niche modeling for reed canarygrass (Phalaris arundinacea) in floodplain forests of the Upper Mississippi River, USA. We used presence and absence of reed canarygrass from US Army Corps of Engineers forest inventory plots sampled between 2008-2018 as our response variable along with several predictor variables derived from...

Passive integrated transponder (PIT) detections across the Upper Klamath River Basin were combined from all fish that were detected making a passage attempt at the Link River Dam fish ladder from 2008 - 2024. In July 2007, four PIT tag antennas (FS1001 Muliplexer transceiver [MUX] units) arrays which were originally installed by Biomark. In October 2023, antennas were upgraded to Biomark...

The U.S. Geological Survey gathered historic aerial photography and remote sensing imagery from a variety of sources for mapping channel change along a 22.5-kilometer reach of the Green River at Gray Canyon near Green River, Utah. Imagery was downloaded in .TIF format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over et al. 2021) using Agisoft Metashape...

These data were compiled to examine analyte concentrations, including mercury and selenium, and stable isotopes in native and non-native fish across rivers in the Upper Colorado River Basin. Data were collected in 2016 and 2017. Tissue samples were collected as whole-body or muscle plugs (biopsies). Tissue samples were analyzed for stable isotopes in 772 samples, for selenium and 54...

This study evaluated the anesthetic properties of dissolved carbon dioxide on six fish species to determine its efficacy for use in sedating wild caught fish for surgeries. Phase I of this study aimed to inform induction time, recovery time, and short-term survival of fish using five different concentrations of carbon dioxide at one water temperature. Phase II determined the induction...

Classified map of crop types in California's Central Valley generated using artificial neural network multilayer perceptron models and Harmonized Landsat-8 Sentinel-2 Landsat 30m (HLSL30) data. The model was trained on data from the year 2021 and validated on the independent year 2022.

This dataset contains more than 37,000 high-resolution images of natural lake bottom habitats containing round goby (Neogobius melanostomus) captured by autonomous underwater vehicles (AUVs). Round goby are invasive to the Laurentian Great Lakes, but are an important prey item for economically valuable predators, and thus of interest to managers. Individual round goby within each image...
