Data

This dataset includes a collection of files related to a project investigating the ecology of six lakes in the Tokopah Basin. The primary purpose of the research project was to understand the dynamics of periphyton growth and the potential relationships with nitrogen and copper concentrations in high elevation lakes of the Sierra Nevada mountains in Sequoia National Park, California...

This data set includes concentrations of selected transformation products (TPs) of the tire antioxidant, 6PPD, including 6PPD-quinone (6PPDQ) and 4-hydroxydiphenylamine (4-HDPA) in water samples collected during a rain event from two urban rivers in the Greater Toronto Area, Ontario, Canada. In addition, mortality data from acute toxicity tests with aquatic larvae of the mayfly...

The dataset includes capture and individual data for silver carp and buffalo from 2022 and 2023. Fish were captured in the Missouri River and tributaries and transported to the Columbia Environmental Research Center, Columbia, MO, USA. Fish were assigned to one of four treatments to examine different sedation techniques for surgical implantation of artificial transmitters: tricaine

The products presented here document conditions at the Little Saint Francis River chat pile restoration site near Fredericktown, Missouri in July 2019. Imagery was collected shortly after the initiation of restoration actions. Images were collected using low-altitude flights of unoccupied aerial systems (UAS, or “drones”) and processed using structure-from-motion techniques to generate...

These data are comprised of measurements of elements (e.g., uranium, cobalt, nickel, copper, zinc, cadmium, lead, etc.), major anions (chloride, nitrite+nitrate as nitrogen, sulfate, etc.), organic carbon, and general water quality parameters measured in Pinyon Plain Mine containment pond water, sediment, vegetation, and aquatic invertebrate samples collected in calendar years 2023 and...

This data set includes acoustic telemetry positions for silver carp ranging in total length from 251 to 359 mm (mean = 294 mm) and weight 131 – 427 g (mean = 231 g) tagged with 795-LD transmitters in four earthen ponds at the Columbia Environmental Research Center, Columbia, MO, USA. Positions were monitored using a 16-hydrophone array in each pond before and during a series of trials...

This data set contains auditory evoked potentials for four species of invasive carp; silver carp, black carp, grass carp, bighead carp, as well as goldfish (100-150 millimeters in total length) and behavioral thresholds on goldfish in a tank (dimensions 240 centimeters X 100 centimeters; depth of 25 centimeters) at the Columbia Environmental Research Center, Columbia, MO USA. Ambient...

This dataset represents active relocations of acoustic and radio telemetry tagged Black Carp among the Mississippi and Missouri rivers near their confluence. These river segments consist of both open river and impounded habitat present during observed hydrologic conditions from 2019-2023. Relocations were primarily on a monthly interval with initial weekly relocations during the first...

Sensory input and systems are critical for organisms to respond to their environment, allowing movement to suitable habitat and potential escape from predators. While many stages of grass carp ontogeny have been described, neurosensory development remains unclear. Using behavioral tests, we looked at phonotaxis and chemotaxis from initial gas bladder inflation to the development of the...

This data release includes sampling location data, laboratory processed surface water chemistry data (anions, cations, total nitrogen, dissolved organic carbon, deuterium, trace metals), laboratory processed pore water chemistry data (anions, cations, total nitrogen, dissolved organic carbon, trace metals), laboratory process sediment data (trace metals), and whole-body trace metal...

Concentrations of a wide variety of environmental organic contaminants were measured in surface waters of the Lake Mead National Recreation Area (Nevada and Arizona) in 2010 to provide a measure of exposure to resident fish species. These contaminants were sampled using the semipermeable membrane device (SPMD) and the polar organic chemical integrative sampler (POCIS) which allow for the

From 2017-2023, a total of 934 Grass Carp were removed from the Lake Erie basin and tributaries, and 159 were captured in the Mississippi, Missouri, and Lamine Rivers within the state of Missouri in 2022. For each captured fish we documented capture location, water temperature; we measured total length and total weight. Length data was used to assess the removal efforts in Lake Erie. A...
