Uptake and toxicity of clothianidin to monarch butterflies from milkweed consumption (ver. 2.0, January 2020) Recent concern for the adverse effects from neonicotinoid insecticides has centered on risk for insect pollinators in general and bees specifically. However, natural resource managers are also concerned about the risk of neonicotinoids to conservation efforts for the monarch butterfly (Danaus plexippus) and need a tool to estimate risk for wild monarch butterflies exposed to clothianidin. In the present study, monarch butterfly larvae were exposed to contaminated milkweed plants from hatch until pupation, and the effects upon larval survival, larval growth, pupation success, and adult mass were measured. Soils dosed with a granular insecticide product lead to average clothianidin concentrations of 10.8 - 843 ng/g...

The Connecticut Department of Transportation collaborated with U.S. Geological Survey (USGS) in a study to improve the flood-frequency estimates in Connecticut and develop regional regression equations for estimating annual exceedance probability discharges at ungaged sites in Connecticut. The results of the study are found in Scientific Investigations Report (http://doi.org/10.3133/sir20205054).

These additions allow us, for the first time, to calculate probabilistic seismic hazard curves for an expanded set of spectral periods (0.01 s to 10 s) and site classes (VS30 = 150 m/s to 1,500 m/s) for the conterminous U.S. (CONUS), as well as account for amplification of long-period ground motions in deep sedimentary basins in the Los Angeles, San Francisco Bay, Salt Lake City, and Seattle regions.

The American burying beetle (ABB) is listed as endangered under the Endangered Species Act, but in 2019 the U.S. Fish and Wildlife Service proposed to reclassify this species as threatened. We applied a deductive model for the ABB that identified potentially suitable habitat using LANDFIRE Existing Vegetation Types (EVT). The habitat model ranked each EVT using one of four categories: (1) favorable; suitable vegetation to support all or critical portions of the ABB life cycle, (2) conditional; favorable only under certain conditions including seasonality of flooding and land management...

Relative-gravity surveys were carried out using a Zero Length Spring, Inc. Burris relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations. Absolute-gravity surveys were carried out using a Micro-g LaCoste, Inc.

Similarly, sensors measuring biological (algal) fluorescence (hereafter referred to as chlorophyll (fChl) and phycocyanin (fPC), have gained popularity to measure phytoplankton concentration, biomass, and even primary productivity.

The U.S. Geological Survey (USGS), in cooperation with the Tennessee Department of Environment and Conservation, Division of Water Resources (TDEC-DWR), compiled available 5-year, county-level data on irrigated acres in Tennessee from 1934 to 2017 from published reports by the U.S. Census Bureau and the U.S. Department of Agriculture.

To advance the understanding of the physical controls on riverbank groundwater discharge processes, discharge zones can be mapped efficiently using handheld and drone-based thermal infrared cameras. Groundwater discharge locations can be identified based on ‘anomalous’ thermal signatures, such as relatively cold riverbank zones in summer and warm riverbank zones in winter. Thermal infrared imaging can be combined with concurrent direct...

As of 2018 there were 15 known strains of aerobic and anaerobic acetylenotrophs, however we hypothesized that there may be yet unrecognized diversity of acetylenotrophs in nature. In this study, we expanded this diversity by isolating an aerobic acetylenotroph, Bradyrhizobium sp. strain I71, from trichloroethene (TCE)-contaminated soils undergoing bioremediation. TCE-contaminated soils from the NASA Ames Research Center in California were used to establish soil microcosms with acetylene as the primary carbon substrate and acetylene...

The equations were developed using annual peak flow data through water year 2015 and basin characteristics for 285 streamflow gaging stations across Pennsylvania and surrounding states. The streamgages included active and discontinued continuous-record stations, as well as crest-stage partial-record stations, and required a minimum of 10 years of annual peak streamflow data for inclusion in the study. Explanatory variables significant at the 95-percent confidence level for one or more regression equations included the following basin characteristics: drainage...

As more data became available, years 2016 through 2019 were added to the dataset. The final dataset consists of 28 rasters in Geostationary Earth Orbit Tagged Image File Format (GeoTIFF), one for each year from 1992 through 2019. The final estimates (in pounds) were derived from several data sources, which include road density and proportion of developed land use, depth and spatial extent of long-term snowfall, and the production and distribution of salt sources by state. The extent is the conterminous United States, and the spatial resolution is one-square kilometer.
