Behavioral response of crayfish to light and the effects on trapping success, laboratory and pond trials, Missouri 2022-2023 Behavioral response of crayfish to light and the effects on trapping success, laboratory and pond trials, Missouri 2022-2023
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)...
Shorthead and silver redhorse movement data from Lake Erie and the Sandusky and Cuyahoga Rivers, Ohio USA from 2022 to 2025 (ver. 2.0, March 2026) Shorthead and silver redhorse movement data from Lake Erie and the Sandusky and Cuyahoga Rivers, Ohio USA from 2022 to 2025 (ver. 2.0, March 2026)
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...
Electro-olfactory and behavioral responses of grass carp, bighead carp, silver carp, and black carp to chemical stimuli in laboratory exposures Electro-olfactory and behavioral responses of grass carp, bighead carp, silver carp, and black carp to chemical stimuli in laboratory exposures
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...
Thiaminase I activity measurements in juvenile black carp, bighead carp, grass carp, and silver carp from lab cultures Thiaminase I activity measurements in juvenile black carp, bighead carp, grass carp, and silver carp from lab cultures
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...
Code and outputs for a mallard reproduction model incorporating migration delays and reduced adult body mass Code and outputs for a mallard reproduction model incorporating migration delays and reduced adult body mass
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...
Development and optimization of species-specific qPCR assays for eDNA detection of the mucket (Ortamannia ligamentina) and spectaclecase (Cumberlandia monodonta) mussels’ male mitotype Development and optimization of species-specific qPCR assays for eDNA detection of the mucket (Ortamannia ligamentina) and spectaclecase (Cumberlandia monodonta) mussels’ male mitotype
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).
Measurement of Per- and Polyfluoroalkyl Substances in Graminaceous plants using three extraction techniques Measurement of Per- and Polyfluoroalkyl Substances in Graminaceous plants using three extraction techniques
Dataset contains measured concentrations of PFAS analytes and limits of detection/quantification for 37 total samples. There are 82 total PFAS analytes (7 non-extracted internal standards, 24 extracted internal standards, and 51 target native analytes) and each individual sample has been quantified for all 82 of these compounds. Samples are extracts of plant tissues from three sources...
Juvenile Virile Crayfish (Faxonius virilis) length, weight, and consumption after a 28-day sublethal nickel exposure with associated water quality data Juvenile Virile Crayfish (Faxonius virilis) length, weight, and consumption after a 28-day sublethal nickel exposure with associated water quality data
Data was collected in association with the exposure of aqueous nickel (NiCl2-H2O) to juvenile crayfish (Faxonius virilis) for 29 days at different concentrations to observe any differences in growth (after 28 days) and food consumption (on day 29). Data for the growth component of the study included crayfish wet weight (initial and final), final carapace length, and crayfish sex. The...
Pickle Pond pre-restoration orthomosaic and elevation products, Superior, Wisconsin, September 2022 Pickle Pond pre-restoration orthomosaic and elevation products, Superior, Wisconsin, September 2022
The orthomosaic, digital surface model and point cloud presented here document conditions at Pickle Pond in Superior, Wisconsin 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 were...
Effects of dietary organic selenium on growth, survival, and reproduction in Hyalella azteca and Chironomus dilutus Effects of dietary organic selenium on growth, survival, and reproduction in Hyalella azteca and Chironomus dilutus
Chronic selenium toxicity thresholds are based primarily on dietary organoselenium exposure and subsequent reproductive effects in fish. Available chronic selenium toxicity data suggests that invertebrates are less sensitive than fish, but chronic invertebrate studies are limited. We evaluated yeast-based diets for chronic toxicity studies with Hyalella azteca and Chironomus dilutus...
Active location of fish telemetry tags of fish in the Mississippi and Missouri rivers, and tributaries, October 2019 – September 2023 Active location of fish telemetry tags of fish in the Mississippi and Missouri rivers, and tributaries, October 2019 – September 2023
This dataset represents coarse active relocations of acoustic transmitters in telemetry tagged fish of various species detected among the Mississippi and Missouri rivers near their confluence. These detections of unknown tagged individuals were incidental and occur within the range and frequency of effort for a focused active telemetry study on invasive carp. These river segments consist...
Mollusk diet of wild caught Black Carp (Mylopharyngodon piceus) from the Mississippi River drainage, 2019 - 2023 Mollusk diet of wild caught Black Carp (Mylopharyngodon piceus) from the Mississippi River drainage, 2019 - 2023
The dataset is an inventory (enumeration and taxonomic identification) of mollusk diet items consumed by wild-caught black carp (Mylopharyngodon piceus), based on the examination of gut contents from black carp collected in the lower Mississippi River drainage of the U.S. in 2019 through 2023.
