Data

This dataset encompasses a series of files related to a comprehensive ecotoxicology research project conducted in high elevation lakes of the Tokopah Basin in Sequoia National Park. The dataset includes detailed sampling data that reflects the copper concentrations at multiple levels of the food web. This dataset also includes morphometric data for collected fish, biomarkers of fish...

This dataset represents passively detected locations of acoustic telemetry tagged Black Carp in the Mississippi and Missouri rivers near their confluence. These river segments consisted of both open river and impounded habitat present during observed hydrologic conditions from 2021-2023. Receiver arrays were set in known use areas (determined by active relocations of tagged fish) and set...

These data include information from 74 sampled stream reaches in the Osage Ecological Drainage Unit (EDU) within the Osage River Basin, Missouri. Streams with a Strahler order from three to six were systematically sampled to assess Niangua darter resource selection across three spatial scales macrohabitat, reach, and watershed scale. Variables used to explain Niangua darter presence at...

This study provides data on the reproductive biology and age of Black Carp (Mylopharyngodon piceus) from various rivers in the Mississippi River Basin. A total of 549 fish samples, collected opportunistically between 2015 and 2023, underwent macroscopic and histological staging to assess reproductive development. Specimens were captured by commercial fishermen and biologists and sent to...

This data set includes survival data for five fish species [Coho Salmon (Oncorhynchus kisutch); Brook Trout (Salvelinus fontinalis); Rainbow Trout (Oncorhynchus mykiss); Smallmouth Bass (Micropterus dolomieu); Largemouth Bass (Micropterus nigricans)] exposed to various concentrations of 6PPD-quinone (6PPDQ) for up to 96 hours and then held in clean water for one week post exposure...

Data include counts and locations of fish captured in the mainstem of the Cuyahoga River from 1984 through 2024. Data were collected by USGS (2022-2024) and the Ohio Environmental Protection Agency (1984-2021) using standardized electrofishing techniques. Data also include site variables such as physical and chemical properties as well as dam removals that occurred within the river basin...

Data were collected in association with the application of visible light in laboratory and field settings to elicit behavioral responses from the invasive virile crayfish (Faxonius virilis). Data for laboratory light trials include water temperature, dissolved oxygen, and conductivity, crayfish sex, weight and size, light lux, proportion of time spent in each zone (lit versus unlit)...

Data include locations where shorthead redhorse (Moxostoma macrolepidotum) and silver redhorse (Moxostoma anisurum) were detected following tagging events in the Sandusky and Cuyahoga Rivers, Ohio, USA. Location data were obtained primarily through stationary acoustic receivers, with additional locations from radio towers and mobile acoustic and radio surveys in the Cuyahoga River. The...

Using juvenile individuals of four species of carp (Family: Cyprinidae), we tested the potential for two amino acids and one commercial bait stimulus to elicit an extracellular electro-olfactory response within the naris using gelatin-based electrodes. The amino acids alanine and lysine were tested on grass carp (Ctenopharyngodon idella), bighead carp (Hypophthalmichthys nobilis), silver...

We measured juveniles from four species, black carp (Mylopharyngodon piceus), bighead carp (Hypophthalmichthys nobilis), silver carp (H. molitrix), and grass carp (Ctenopharyngodon idella), for thiaminase activity. These data provide previously unknown information about thiaminase activity of three emerging threats (bighead carp, black carp, and grass carp) to the Great Lakes. We tested...

These data are outputs from a mallard (Anas platyrhynchos) reproduction model that accounts for breeding ground arrival time and the body mass of individuals. Specifically, adult female mallards that arrive late or with lower body mass have the potential for lower clutch sizes and are less likely to renest if a nest fails. The model is based on an existing mallard reproduction model that...

This dataset describes the sensitivity (limit of detection and limit of quantification) and specificity (list of species tested against the assays) of two qPCR assays designed to detect the male mitotype of two freshwater mussel species Ortmanniana ligamentina and Cumberlandia monodonta from water samples (eDNA).
