Chemical Cues Which Include Amino Acids Mediate Species-Specific Feeding Behavior in Invasive Filter-Feeding Bigheaded Carps-Data
This data was generated from a study in which five experiments were conducted that tested whether and how dissolved chemicals might assist food recognition in two filter-feeding fishes, the silver (Hypophthalmichthys molitrix) and the bighead carp (H. nobilis). The buccal-pharngeal pumping (BPP), a behavior in which fish pump water into their buccal cavities, was observed in both silver and bighea
Data for Comparison of Size, Terminal Fall Velocity, and Density of Bighead, Silver, and Grass Carp Eggs for use in Drift Modeling
Invasive Asian carps established in the United States spawn in turbulent water of rivers and their eggs and early larvae develop while drifting in the current. The eggs are slightly denser than water and are held in suspension by water turbulence. The eggs are believed to perish if they settle before hatching. It is thus possible to use egg drift modeling to assess the capability of a river to s
Reproductive strategy, spawning induction, spawning temperatures and early life history of captive sicklefin chub Macrhybopsis meeki-Data
Macrhybopsis reproduction and propagule traits were studied in the laboratory using two temperature regimes and three hormone treatments and which methods produced the most spawns. Only sicklefin chub (M. meeki) spawned successfully although sturgeon chub (M. gelida) released unfertilized eggs. All temperature and hormone treatments produced M. meeki spawns, but two treatments had similar success
A comparison of four pore water sampling methods for mixed metals and dissolved organic carbon, and implications for toxicity evaluations-Data
These replicate data support the findings described in the publication, "A comparison of four pore water sampling methods for mixed metals and dissolved organic carbon, and implications for sediment toxicity evaluations" by Danielle Cleveland, William G. Brumbaugh, and Donald D. MacDonald (Environmental Toxicology and Chemistry 2017). The data represent comparison of four commonly-applied techniqu
Toxicity and chemistry data from an evaluation of metal-contaminated sediments from the Upper Columbia River, Washington, 2013-2014
This resource contains chemistry and toxicity data from sediment toxicity tests conducted by the USGS Columbia Environmental Research Center with 66 sediment samples collected from in and around the Upper Columbia River in the fall of 2013. Toxicity testing was conducted from fall 2013 through summer 2014 with the amphipod, Hyalella azteca, the midge Chironomus dilutus, and the mussel Lampsilis si
Data tables in support of manuscript "δ13C and δ15N in the Endangered Kemp's Ridley Sea Turtle Lepidochelys kempii After the Deepwater Horizon Oil Spill"
The Deepwater Horizon explosion and oil spill in April 2010 released 3.19 million barrels of MC252 crude oil into important foraging areas of the endangered Kemps ridley sea turtle (Lepidochelys kempii; Lk) in the northern Gulf of Mexico (GoM). We measured delta-13 C and delta-15 N in scute biopsy samples from Lk that nested in Texas during 2010-12. Satellite-tracked Lk returned to traditional nor
Acute sensitivity of the vernal pool fairy shrimp, Branchinecta lynchi (Anostraca; Branchinectidae), and surrogate species to ten chemicals-Data
The vernal pool fairy shrimp, Branchinecta lynchi, (Branchiopoda; Anostraca) and other fairy shrimp species have been listed as threatened or endangered under the United States Endangered Species Act (ESA). There is little information about the sensitivity of Branchinecta spp. to toxic effects of contaminants, making it difficult to determine whether they are adequately protected by water quality
Quantifying habitat benefits of channel reconfigurations on a highly regulated river system, Lower Missouri River, USA-Data
Data set contains depth and velocity grids generated from hydrodynamic model (SRH-2D) simulations run for a range of discharges. Date range corresponds to month(s) that bathymetric survey was performed. Three study reaches were considered in this analysis: the Fairview reach of the Yellowstone River, MT, the Miami and Lisbon-Jameson reaches of the Lower Missouir River. Data and application are des
Amphibian acoustic data from the Arizona 1, Pinenut, and Canyon breccia pipe uranium mines in Arizona.
USGS is currently conducting biological surveys associated with uranium mines on federal lands in Arizona. These surveys include determining the composition of the local amphibian community at Canyon, Arizona 1, and Pinenut mines near the Grand Canyon. To aid in determining the amphibian species present at each mine site, we used acoustic monitoring recorded with a SM3Song Meter (Wildlife Acoustic
Microsomal EROD data of fish liver sample assay from species collected in the Salt and Gila Rivers, Arizona
This dataset includes microsomal EROD data from a liver sample assay. The samples are from several fish species that live in the Salt and Gila rivers, Arizona at sites that are being assessed for PBDE contamination. The data was created in September and October 2016.
Chemistry, radiation and histopathology data in support of manuscript "Pre-mining trace element and radiation exposture to biota from a breccia pipe uranium mine in the Grand Canyon (Arizona, USA) watershed"
The risks to wildlife and humans from uranium (U) mining to the Grand Canyon watershed are largely unknown. In addition to U, other co-occurring ore constituents contribute to risks to biological receptors depending on their toxicological profiles. This data was collected to characterize the pre-mining concentrations of total arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), mercury (Hg), nicke
Acoustic Doppler current profiler raw measurements on the Missouri and Yellowstone rivers, 2000-2016, Columbia Environmental Research Center
Between the years 2000 and 2016, scientists and technicians from the U.S. Geological Survey (USGS) Columbia Environmental Research Center (CERC) have collected over 400 field-days worth of acoustic Doppler current profiler (ADCP) measurements on the Missouri and Yellowstone Rivers, primarily for the purposes of assessing physical aquatic habitat for the pallid sturgeon.
