Data

This project contains data and supporting files from hydrodynamic and particle tracking models of the Missouri River at Searcys Bend developed in conjunction with an experimental dye release at the study site on March 5, 2021. The main objectives of this effort were to develop a hydrodynamic model using topographic and flow data collected in the field for subsequent use in a particle tracking mode

This dataset consists of seven geomorphic variables attributed to standard river mile address points at 0.1 mile (160 m) intervals between Fort Peck Dam and the headwaters of Lake Sakakawea. The data illustrate the geomorphic variation in this 300-km segment of the Upper Missouri River and are indicative of channel complexity, thought to be an important influence on dispersal and retention of larv

Data describe a designed environmental DNA (eDNA) survey for the detection of oyster mussel (Epioblasma capsaeformis) from field collected water samples. Parameters described include the limit of detection and limit of quantification of the assay; a list of freshwater mussel species tissue samples that were used to test specificity of the assay; and field collected water samples that were tested t

We determined the acute toxicity of four wildland fire retardants (Phos-Chek 259-Fx, Phos-Chek MVP-Fx, and Phos-Chek LC-95A-Fx, and Phos-Chek LC-95A-R) to two life stages (swim-up fry and young juveniles) of rainbow trout in standardized hard and soft water. The measure of acute toxicity was expressed as both the 96-hour median lethal concentration (96-h LC50, based on mortality) and 96-h median e

Data describe a designed environmental DNA (eDNA) survey for the detection of Spectaclecase (Cumberlandia monodonta, also referred to as Margaritifera monodonta) from field collected water samples. Parameters described include the limit of detection and limit of quantification of the assay; a list of freshwater mussel species tissue samples that were used to test specificity of the assay; and fiel

Data describe a designed environmental DNA (eDNA) experiment for the estimation of eDNA degradation rates for the spectaclecase (Cumberlandia monodonta) from water samples collected in the laboratory. Parameters described include laboratory collected water samples that were tested to estimate concentration of spectaclecase DNA and associated quality assurance data. Samples were collected from expe

This dataset contains the results of a laboratory chronic bioassay with 6-week-old juvenile mussels (Fatmucket, Lampsilis siliquoidea) in a 28-day zinc exposure (120 and 240 micrograms zinc per liter) with endpoints of survival and growth (biomass and length) following standard ASTM methods. Surviving mussels were transferred from the control and treatment groups into a culture pond and their surv

Survival, behavior, reproduction, morphometric measurements, and tissue analyses of crayfish, mussels, and fish from acute toxicity tests with pyrethroid pesticides. Exposure and recovery water quality data are also included for quality assurance purposes.

This dataset provides results for the following: (1) metals concentrations in soils surrounding breeding song bird nest sites; (2) metals concentrations in invertebrates (earthworm and grub composites) collected near nest sites; (3) metals concentrations and delta-aminolevulinic acid dehydratase (ALAD) activity in avian blood samples; and (4) metals concentrations, indicators of oxidative stress a

This data set documents results of analysis of samples collected from the Arctic National Wildlife Refuge during Summer 2019. Data tables include: 1. The numeric and alphanumeric identifiers for samples collected for this study and the dates these samples were collected; 2. Results data containing concentration values of individual polycyclic aromatic hydrocarbon compounds in sediment, soil, and v

Using juvenile individuals of 3 species of carp (Family: Cyprinidae), we tested the potential for six amino acids to elicit an extracellular electro-olfactory response within the naris using gelatin-based electrodes. The amino acids L-alanine, L-arginine, L-aspartic acid, L-asparagine, L-glutamine, and L‑glutamic acid were tested on Grass Carp (Ctenopharyngodon idella), Bighead Carp (Hypophthalmic

Data consists of dose, dose method, solvent, weight, length and survival of test species from bioassays following an Up-and-Down method conducted with Ziram.
