Stable carbon and nitrogen isotope values in muscle tissue of bigheaded carps and native filter-feeding fish from the lower Missouri River, USA, 2005-2006 Stable carbon and nitrogen isotope values in muscle tissue of bigheaded carps and native filter-feeding fish from the lower Missouri River, USA, 2005-2006
Fish muscle tissue was analyzed for stable carbon and nitrogen isotope values (delta 13C and delta 15N) for two filter-feeding fishes native to China, silver carp (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis), and three native filter-feeding fish including bigmouth buffalo (Ictiobus cyprinellus), gizzard shad (Dorosoma cepedianum) and paddlefish (Polyodon...
Organochlorine chemicals in northern cardinal eggs from suburban Washington, DC USA Organochlorine chemicals in northern cardinal eggs from suburban Washington, DC USA
Analysis of organochlorine pesticides and polychlorinated biphenyls (PCBs) in northern cardinal eggs from six neighborhoods near Washington, DC
Chemistry data for assessment of crayfish from Madison County, Missouri lead mines 2015 Chemistry data for assessment of crayfish from Madison County, Missouri lead mines 2015
These data are comprised of measurements of metals (cobalt, nickel, copper, zinc, cadmium, and lead), anions (fluoride, chloride, nitrite, bromide, nitrate, sulfate, and phosphate), dissolved organic carbon, and major cations (sodium, magnesium, potassium, calcium, manganese, iron, and strontium) in surface and pore water samples collected during an assessment of the impacts of mining...

Female Faxonius (formerly Orconectes) quadruncus broodstock collected for toxicity testing Female Faxonius (formerly Orconectes) quadruncus broodstock collected for toxicity testing
Broodstock individual Faxonius quadruncus were collected for culturing eggs until hatch. Hatchling crayfish were used to be used in toxicity testing to assess hazards of metals mixtures to young Faxonius quadruncus
Development of a dual luciferase-fluorescamine assay adapted to a 384 micro-well plate format-Data Development of a dual luciferase-fluorescamine assay adapted to a 384 micro-well plate format-Data
We have adapted two commonly used human breast luciferase transactivation cell bioassays, the recently re-named estrogen agonist/antagonist screening VM7Luc4E2 cell bioassay (previously designated BG1Luc4E2) and the androgen/glucocorticoid screening MDA-kb2 cell bioassay, to 384-well formats for HTS of endocrine-active substances. This cost-saving adaptation includes a fast, accurate...
Missouri River Bend Classification Missouri River Bend Classification
Management actions intended to increase growth and survival of pallid sturgeon (Scaphirhynchus albus) age-0 larvae on the Lower Missouri River require a comprehensive understanding of the geomorphic habitat template of the river. The datasets described here are intended to support decisions relating to where channel-reconfiguration projects should be located to optimize effectiveness of
Asian Carp Acoustic Stimuli Data Asian Carp Acoustic Stimuli Data
Invasive silver carp (Hypophthalmichthys molitrix) occur in large regions of the Mississippi River drainage, outcompete native species, and are notorious for their prolific jumping behavior. Juvenile and adult (up to 25 kg) carp are known to jump up to 3 m above the water surface in response to moving watercraft. Broadband sound recorded from an outboard motor (100 hp at 32 km/hr) can...
Widespread Legacy Brine Contamination from Oil Shales Reduces Survival of Chorus Frog Larvae-Data Widespread Legacy Brine Contamination from Oil Shales Reduces Survival of Chorus Frog Larvae-Data
Advances in drilling technique have facilitated a rapid increase in hydrocarbon extraction from energy shales, including the Williston Basin in central North America. This area overlaps with the Prairie Pothole Region and greater than 35% of wetlands are less than or equal to 1 km from a petroleum-related well. Legacy practices often released saline co-produced waters (brines) that were...
Chemical Cues Which Include Amino Acids Mediate Species-Specific Feeding Behavior in Invasive Filter-Feeding Bigheaded Carps-Data 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...
Data for Comparison of Size, Terminal Fall Velocity, and Density of Bighead, Silver, and Grass Carp Eggs for use in Drift Modeling 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...
Reproductive strategy, spawning induction, spawning temperatures and early life history of captive sicklefin chub Macrhybopsis meeki-Data 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...
