Data

Data describe designed environmental DNA (eDNA) laboratory experiments for the estimation of eDNA shedding and degradation rates for adult Mucket (Ortmanniana ligamentina) at different biomass densities in a closed system. Parameters described include descriptions of laboratory collected water samples that were tested to estimate concentration of Mucket DNA, qPCR results and associated...

This project contains design parameters and an overview of the hydraulic characterization of the U.S. Geological Survey (USGS), Columbia Environmental Research Center (CERC) eco-flume. The eco-flume was designed in collaboration with the St. Anthony Falls Laboratory at the University of Minnesota to explore complex ecological phenomena that occur in natural rivers. The overall design was...

This data describes the relative luminescence units (RLUs) and relative fluorescence units (RFUs) of lysates of estrogen responsive chemically-activated luciferase expression human breast carcinoma VM7LucERbeta9 cells which were exposed for 24 h to 17beta-estradiol dilutions, or dilutions of sediment extracts collected from various locations within the Conasauga River Basin in the...

This data release supports a pilot laboratory study evaluating the bioaccumulation and reproductive effects of dietary selenium on the endangered Topeka shiner (Notropis topeka). Adult fish were exposed under controlled flow-through conditions to three diets containing graded concentrations of seleno-L-methionine (control, 5.50, and 14.0 micrograms Se/g dry weight) to simulate...

Accurate age data is essential for modeling fish population dynamics and informing management decisions. Estimating age in cyprinid fishes like the invasive silver carp is challenging. During this study we evaluated precision and bias in age estimates of silver carp collected from the Illinois River, Illinois using seven structures: the first and second section of the ossified pectoral...

These datasets document locations of and water temperature recorded by Hobo Water Temp Pro series loggers (Onset Computer Corp., Bourne, MA) deployed by the USGS Comprehensive Sturgeon Research Project at up to 31 locations in the Lower Missouri River (from the Gavins Point Dam near Yankton, South Dakota to its confluence with the Mississippi River near St. Louis, Missouri) and 7...

These datasets document locations of and water temperature recorded by Hobo Water Temp Pro series loggers (Onset Computer Corp., Bourne, MA) deployed by the USGS Comprehensive Sturgeon Research Project at up to 29 locations in the Lower Missouri River (from the Gavins Point Dam near Yankton, South Dakota to its confluence with the Mississippi River near St. Louis, Missouri) and 7...

The Powder River from Broadus, Montana to Terry, Montana was surveyed from June 13-19, 2025 to map the range of habitats, including spawning habitats available to be used by the endangered pallid sturgeon (Scaphirhynchus albus). Pallid sturgeon typically occupy the Powder River in the spring to early summer in years when flows are high. We surveyed potential spawning habitats and...

The orthoimagery, digital surface model and point cloud presented here document conditions at the Ashtabula River Area of Concern in Ashtabula, Ohio in September 2021. Imagery documents the result of in-stream and terrestrial habitat restorations that had occurred in 2012. Aerial images were collected using a DJI Phantom with FC6310 sensor flying at a nominal elevation of approximately...

The orthomosaic, digital surface model and point cloud presented here document conditions at Cuyahoga Gorge Reservoir in Cuyahoga Falls, Ohio in September 2022, prior to planned ecological restoration. Images were collected using a 3D Robotics Solo aircraft with GNSS GPS upgrade, Mission Planner software, and a Pentax Ricoh GRII 3-band digital camera sensor. Imagery acquisition flights...

In March and September of 2015, the USGS demonstrated the utility of side-scan sonar to image large densities of invasive carp and estimate water volume on the Lamine and Blackwater Rivers, Cooper County, Missouri, USA. A 30-kilometer reach of the Lamine River and 20-kilometer reach of the Blackwater River were surveyed using a Humminbird 1198c sonar system. Fish sampling was conducted...

This data set provides lists of plant species observed in 2017 at Fernald Preserve in southwest Ohio, USA using two different survey methods. “Tier1_species.txt” provides a list of plant species observed in a cursory walk-through survey at 8 restored grassland sites. “Tier3_3pecies.txt” provides a list of plant species observed in 44 circular plots (18.5 ft radius or 0.025 acres each)...
