Water chemistry data observed in experimental laboratory mesocosms exposed to different nitrapyrin and nitrogen amendments in the presence or absence of a nitrifier enriched microbial (NEM) community

These data describe the results of a controlled laboratory mesocosm experiment evaluating the effect of nitrapyrin, a nitrification inhibitor, on nitrification in a nitrifier enriched microbial (NEM) community. Parameters described include the water chemistry and nitrapyrin measurement results of experimental mesocosms. Microbial community data is described in a separate data release.

Growth and survival of a Unionid Mussel (Fatmucket, Lampsilis siliquoidea) and a Common Test Benthic Organism (Amphipod, Hyalella azteca) during Chronic Exposures to Mixtures in Sediment Contaminated by Unregulated Industrial Discharges.

This data set contains toxicity data from 28- and 84-day sediment bioassays to assess the effects of contaminated Kanawha River, West Virginia sediment on juvenile mussels (fatmucket, Lampsilis siliquoidea) and one commonly tested benthic invertebrate (amphipod, Hyalella azteca) following ASTM standard methods for conducting 4-week sediment toxicity tests with the mussel and amphipod. In addition,

Dike Fields and Macrohabitats of the Lower Missouri River

This project summarizes broad, two-dimensional spatial availability of fish habitat across the Lower Missouri River (from its confluence with the Big Sioux River near Sioux City, Iowa downstream to its confluence with the Mississippi River near St. Louis, Missouri). One of the main objectives of the project was to delineate and categorize dike fields, which we define as areas directly downstream f

Salinity tolerance of grass carp and silver carp during egg and early larval stages

We tested salinity tolerance of grass carp and silver carp eggs and larvae during two phases of development – pre-gas bladder inflation and post gas bladder inflation to the development of the second gas bladder chamber, using 6 different salinity concentrations ranging from 0 to 36 ppt. Growth and developmental rates were also observed after exposure. After the initiation of horizontal swimming,

Light trap and larval trawl collection of bigheaded carp in the Missouri River Basin, 2016

In the Lamine, Moreau, and Little Chariton rivers, light traps were used to capture larval bigheaded carps moving into tributaries. Traps were set on a weekly basis in each river, at roughly 1-kilometer intervals up to 7 km upstream. Ichthyoplankton tows were done in locations near the confluence of each tributary with the Missouri River, and within the Missouri River itself. Data includes identif

Invasive carp harvest data and surveys of commercial fishers in support of stock assessment and abundance models, Kentucky Lake and Lake Barkley, 2009-2021

The Kentucky Department of Fish and Wildlife Resources and Tennessee Wildlife Resource Agency conducted observations onboard commercial fishing vessels. During these observations total lengths were collected from a subset of that capture which we have used to develop a length-based stock assessment of invasive carp. The first dataset represent harvest from the invasive carp harvest program in Kent

Results of elemental analyses of desert tortoise (Gopherus agassizii) burrow spoil and undisturbed surficial soils in California, 2023

Bighorn sheep (Ovis canadensis) were frequently photographed by wildlife cameras when they visited desert tortoise (Gopherus agassizii) burrows in the eastern San Bernardino Mountains near Palm Springs, California, USA (Mesa Windfarm). A previous study suggested that sheep may have been utilizing the excavated spoil material from burrows as a mineral lick. We aimed to test this possibility by coll

Chemical and Biological Data from a Study on Evaluation of Survival and Growth of Fatmucket (Lampsilis siliquoidea) in Short-Term Chronic Toxicity Tests with Nickel and Ammonia

Short-term 7-day ammonia and nickel toxicity tests were conducted with juvenile Fatmucket. This data release reports individual biological, chemical, and water quality measurements in each toxicity test.

Supporting files for a Langrangian particle tracking model evaluation of sediment exposure and burial for freshwater mussels

This project contains field data and supporting files for a Lagrangian particle tracking (LPT) model at a representative reach on the Osage River, Missouri. Field datasets include a topobathymetric digital elevation model (DEM) for a 5-km reach of the Osage River, water surface elevation profiles, and velocity data collected with acoustic Doppler current profiler (ADCP). Channel topography was gen

Supporting files for particle tracking simulations of the Upper Missouri River near Wolf Point, MT

This dataset contains supporting files for particle tracking simulations of the Upper Missouri River near Wolf Point, MT.

Development of High Surface Area Organosilicate Nanoparticulate Thin Films for Use in Sampling Hydrophobic Compounds in Sediment-Data

The data set describes the characterization of organosilica nanoparticle thin films used to adsorb PCBs from laboratory water and a sediment collected near Anniston Alabama. Data not shown here for the porewater and sediment PCB concentrations can be found in Appendix 1 of Ingersoll et al. 2014 ( Bulk sediment chemistry was obtained from Table A1-3a.Porewater

Grass Carp Movement and Capture Data from the Sandusky River, Lake Erie, Ohio, USA from 2020 to 2022

Data includes grass carp position and sampling data from 2020 to 2022. We used grass carp that were implanted with acoustic transmitters. The position data was generated in Fathom Position from receivers that composed several VEMCO Positioning Systems (VPS). We also queried the Great Lakes Acoustic Telemetry Observation Network (GLATOS) to obtain non-VPS position detections from receivers made fro
