Per- and polyfluoroalkyl substance concentrations in water, sediment, particulates, and biota in stream and riparian food webs in the Farmington River watershed (Connecticut, USA), 2020-2023 Per- and polyfluoroalkyl substance concentrations in water, sediment, particulates, and biota in stream and riparian food webs in the Farmington River watershed (Connecticut, USA), 2020-2023
This dataset includes a collection of files related to a project investigating concentrations of per- and polyfluoroalkyl substances (PFAS) in biotic and abiotic compartments of five stream food webs in the Farmington River watershed, Connecticut, USA. The dataset contains aqueous, sediment, and tissue concentrations of 28 PFAS compounds, 19 of which were detected at least once. Aqueous
Condition of invasive and native aquatic plants exposed to varied water temperature, chlorine concentration and exposure time Condition of invasive and native aquatic plants exposed to varied water temperature, chlorine concentration and exposure time
Data include treatment water chemistry data (Chlorine concentration, Dissolved oxygen, water conductivity, pH, alkalinity, and hardness) and condition of test plants evaluated 24 hours after testing and then every 4 days for 30 days. Treatment water chemistry data was collected at the beginning and end of the plant treatment period and a subset of times during the treatment period. Plant...
Response of grass carp eggs to turbulence Response of grass carp eggs to turbulence
We examined enhanced turbulence levels as an alternative grass carp (Ctenopharyngodon idella) control strategy through turbulence-induced mortality at embryonic stages. We exposed pre-water-hardened and water-hardened grass carp eggs to increased levels of turbulence in a grid-stirred turbulence tank to find threshold values of turbulence parameters and shear stresses that have lethal...
Acute and chronic toxicity of uranium mine water on the mayfly (Neocloeon triangulifer) before and after zero-valent iron treatment Acute and chronic toxicity of uranium mine water on the mayfly (Neocloeon triangulifer) before and after zero-valent iron treatment
Acute (96-h) and chronic (14-d) toxicity of uranium pond water, before and after zero-valent iron treatment, was evaluated using the mayfly Neocloeon triangulifer. Water chemistry data characterizing the laboratory-synthesized waters used in the experiment include specific conductance, pH, alkalinity, major-ion, and metal concentrations. Water quality data collected from the test waters...
Data from Ammonia Toxicity exposures with Threatened, Endangered, and At-Risk Freshwater Mussels with a Co-stressor of an Elevated Temperature or Metal Mixture Data from Ammonia Toxicity exposures with Threatened, Endangered, and At-Risk Freshwater Mussels with a Co-stressor of an Elevated Temperature or Metal Mixture
This dataset provides water-quality measurements and biological response data from 96-hour acute and 7-day chronic laboratory toxicity tests evaluating the effects of ammonia on juvenile freshwater mussels under multiple environmental stressors. Tests were conducted with Green Floater (Lasmigona subviridis), Neosho Mucket (Lampsilis rafinesqueana), and Fatmucket (Lampsilis siliquoidea)...
Respiration and Clearance Rate Data from Subadult Fatmucket (Lampsilis siliquoidea) at Two Different Temperatures Respiration and Clearance Rate Data from Subadult Fatmucket (Lampsilis siliquoidea) at Two Different Temperatures
This data release contains respiration and clearance rate data collected from laboratory experiments. Fatmucket mussels (Lampsilis siliquoidea) were placed in sealed containers to determine their oxygen consumption and excretion rates at two different environmentally relevant temperatures. Mussels were then placed into containers with food to determine how quickly they consume 2-60...
Pre-restoration orthomosaic and elevation products for Erie Ponds at Duluth, Minnesota, August 2020 Pre-restoration orthomosaic and elevation products for Erie Ponds at Duluth, Minnesota, August 2020
The orthoimagery, digital surface model and point cloud presented here document conditions at Erie Ponds of the St. Louis River Area of Concern in Duluth, Minnesota in August 2020, prior to planned ecological restoration. Aerial images were collected using a DJI Phantom with FC6310 sensor at a nominal elevation of approximately 100 meters above the surface of the lake water. Data were...
Fish capture data from the Colorado River, TX, December 15, 2014 through September 23, 2017 Fish capture data from the Colorado River, TX, December 15, 2014 through September 23, 2017
This dataset describes fishes associated with the lower Colorado River basin in central Texas. The dataset is comprised of 1,835 records of individual fishes collected by boat electrofishing at 36 sites in Bastrop, Travis, Fayette, and Colorado counties from December 2014 through September 2017. Each record reports the collection date, county, river basin, gear type, scientific name...
Known age, pond-spawned Gray Redhorse (Moxostoma congestum) length data Known age, pond-spawned Gray Redhorse (Moxostoma congestum) length data
This dataset comprises 20 records of length and weight measurements from juvenile Gray Redhorse (Moxostoma congestum) derived from Colorado River, Texas parentage. These individuals were spawned in April 2021 and measured at the time of sacrifice in July 2022. Each record reports common name, scientific name, total length in millimeters, weight in kilograms, sex and maturity stage...
Pre-restoration orthomosaic and elevation products for Lincoln Park, Milwaukee, Wisconsin, August 2021 Pre-restoration orthomosaic and elevation products for Lincoln Park, Milwaukee, Wisconsin, August 2021
The orthoimagery, digital surface model and point cloud presented here document conditions at Lincoln Park in Milwaukee, Wisconsin. Photos were collected in August 2021, prior to planned ecological restoration within the Milwaukee Estuary Area of Concern. Aerial images were collected using a DJI Phantom with FC6310 sensor at an elevation of approximately 100 meters above the study site...
Otter Creek pre-restoration orthomosaic and elevation products for the Maumee Area of Concern, Toledo, Ohio, September 2020 Otter Creek pre-restoration orthomosaic and elevation products for the Maumee Area of Concern, Toledo, Ohio, September 2020
The orthomosaic, digital surface model and point cloud presented here document conditions at Otter Creek in Toledo, Ohio in September 2020, prior to planned ecological restoration. The study site is part of the Maumee Area of Concern being restored as part of the Great Lakes Restoration Initiative. Aerial images were collected using a DJI Phantom with FC6310 sensor at an elevation of...
Environmental DNA (eDNA) monitoring of invasive bigheaded carp (Hypophthalmichthys spp.) before and after the 2018 mass removal effort at Creve Coeur Lake, St. Louis County, Missouri Environmental DNA (eDNA) monitoring of invasive bigheaded carp (Hypophthalmichthys spp.) before and after the 2018 mass removal effort at Creve Coeur Lake, St. Louis County, Missouri
Data describe environmental DNA (eDNA) concentrations from invasive silver (Hypophthalmichthys molitrix) and bighead carp (H. nobilis), collectively called bigheaded carps (Hypophthalmichthys spp.), from Missouri’s Creve Coeur Lake and Mallard Lake before and after a mass carp removal effort in 2018 at Creve Coeur Lake (2018-01-29). Six sampling trips occurred from 2017-2018, with 3...
