The health of soils along roadways is critical for maximizing habitat quality and minimizing negative ecological effects of roads. Adjacent to unpaved roads, soil chemistry may be altered by the deposition of dust, as well as by road treatment with dust suppressants or soil stabilizer products. If present in roadside soils, these product residues may be available to plants, terrestrial invertebrates, or small mammals. Unfortunately, very few studies have attempted to track the transport of dust suppressants after application. As part of a larger ongoing study on the environmental effects of dust suppressant products on roadside plants and animals, we sampled roadside soils at Loess Bluff National Wildlife Refuge...
This data release includes sampling location data, field-collected wetland attribute data, field-collected water chemistry data, laboratory-processed water chemistry data (anions, cations, alkalinity, nutrients, chlorophyll a concentrations, dissolved organic carbon, and specific ultraviolet absorbance, pesticide concentrations), dry mass of adult aquatic insects emerging from the surface of the wetlands, taxonomic classifications of the insects collected, and whole-body pesticide concentrations for adult aquatic insects emerging from wadeable wetlands in cropland and grassland landscapes across a salinity/hydrology gradient (N = 14 wetlands in 2015, N = 15 wetlands in 2016). Sampling was completed in late spring,...

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 rates at 44 and 43%, consisting of a constant daily temperature with no hormone added, or daily temperature fluctuations with hormone added to the water. Spawns consisted of multiple successful demersal circular swimming spawning embraces interspersed with circular swims without embraces. The most spawns observed for one...

Attributes measured to estimate total fecundity for two Macrhybopsis species typically found in the lower Missouri river
Dust suppressants and soil stabilizer products are applied to unpaved roads worldwide to reduce dust production and stabilize road surfaces. Although these products may enter roadside surface water through runoff or leaching, little information is available on environmental fate or aquatic toxicity. The data reported here include the acute toxicity of 27 dust suppressant/soil stabilizer products to juvenile rainbow trout (Oncorhynchus mykiss) and the acute toxicity of selected products to fatmucket mussels (Lampsilis siliquoidea), virile crayfish (Faxonius virilis), pond snails (Lymnaea stagnalis), and larval gray treefrogs (Dryophytes versicolor). Selected products were also tested after exposure to simulated weathering...
Survival and size of mayflies at each life stage, as well as MeHg concentrations in diatoms and mayflies exposed to low and high MeHg concentrations and a range of selenomethione (SeMet) concentrations.

Containment ponds at uranium mines in the Grand Canyon region have been suspected to pose an attractive nuisance to local wildlife in this arid landscape. To determine the presence of bird species at uranium mine openings, we surveyed the bird community in the area surrounding the mines repeatedly within one year and summarized species occurrence. We observed 35 species of birds directly using the uranium mine containment ponds including species of conservation concern, Pinyon Jay Gymnorhinus cyanocephalus and Brewer’s Sparrow Spizella breweri.

Following an explosion at the Deepwater Horizon drilling rig on April 20, 2010, MC252 an estimated 3.19 million barrels of oil leaked into the Northern Gulf of Mexico over 87 days. The endangered Kemp's ridley sea turtle (Lepidochelys kempii [Lk]) has a long established record of using the area near the well as primary foraging grounds. Resulting short- and long-term negative impacts of the oil spill on sea turtles could induce changes in the health and fitness of the Lk population. MC252 oil is known to have entered the foraging areas. Consequently, stable carbon and nitrogen isotope signatures from MC252 oil should be reflected in the food web and in the tissues of organisms such as sea turtles. We measured carbon...

This data release includes sampling location data, field-collected water chemistry data, cation and anion concentration data for water and tissues of submerged aquatic vegetation, aquatic insect larvae, adult aquatic insects and riparian spiders from 35 first- and second-order sub-alpine streams that ranged over several orders of magnitude in metal concentrations but were similar in elevation, geology, and stream morphology. Sampling was completed in late summer, after snowmelt runoff was complete and as the streams approached baseflow conditions.
Lead (Pb) and calcium (Ca) concentrations were measured in fillet samples of longear sunfish (Lepomis megalotis) and suckers (Catostomidae) collected in 2005‒12 from the Big River, which drains a historical mining area in southeastern Missouri, where a consumption advisory is in effect due to elevated Pb concentrations in fish. Regression analysis indicated that fillet Ca explained 75‒>99% of fillet Pb variation in mining-affected stream reaches. We used analysis-of-covariance to standardize Pb concentration to a common Ca concentration (415 ug/g wet weight), which reduced differences between taxa. Variation among sites and years also was reduced after Ca-normalization, as was the number of samples that exceeded...

Consumption rates and total mercury concentration of food items and consumers collected at six sites on the Colorado River in the Grand Canyon. Sites ranged from 0-367 river kilometers downstream of Lees Ferry (AZ, USA). Samples were analyzed for total Hg using cold vapor atomic fluorescence (CVAF, Tekran Model 2600 CVAF spectrometer) following EPA Method 7474. Consumption rate samples were collected quarterly from July 1, 2007 to June 30, 2009. Food items and consumers were collected June 12-28 2008.
