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
Full Annual Cycle Bioenergetics model of migration applied to Galapagos tortoisesData
Ambient-shade temperature was measured every 4 h with iButton thermochrons (Maxim Integrated Products, Inc., Sunnyville, CA, USA) placed at 1m above-ground level for a previous paper (Blake et al., 2012 DOI 10.1111/1365-2656.12020). The Normalized Difference Vegetation Index (NDVI) of the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument (Huete et al. 2002 - http://dx.doi.org/10.10
Assessment of Contemporary Genetic Diversity and Inter-Taxa/Inter-Region Exchange of Avian Paramyxovirus Serotype 1 in Wild Birds Sampled in North America, 1986-2014
Data set pertaining to avian paramyxovirus (APMV-1) sequences used in phylogenetic analyses. Data contains GenBank Accession numbers, host species common name and taxonomic order, collection year, and collection location.
Oceanographic and Water-Quality Measurements collected south of Marthas Vineyard, MA, November-December 2015
Two platforms were deployed at adjacent sites near the Marthas Vineyard Coastal Observatory (MVCO) to compare their ability to measure bottom shear stress. One platform was a low-profile (20 cm-high) sled, and the other platform was a large (2.5-m high) quadpod. Both platforms supported a pair of single-point acoustic-Doppler current meters and an acoustic-Doppler current profiler. On the sled, th
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
Nitrogen cycling rates from sagebrush and cheatgrass-invaded soils in the Northern Great Basin (2008)
This dataset contains data supporting the paper: DeCrappeo, N.M., DeLorenze, E.J., Giguere, A.T., Pyke, D.A., and Bottomley, P.J. Fungal and bacterial contributions to nitrogen cycling in cheatgrass-invaded and uninvaded native sagebrush soils of the western USA (accepted at the journal Plant and Soil). The purpose of the study was to evaluate the relative contributions of soil bacteria and fungi
Geochemical Database for the National Brackish Groundwater Assessment of the United States
Brackish groundwater (BGW), defined for this assessment as having a dissolved-solids concentration between 1,000 and 10,000 milligrams per liter, is an unconventional source of water that may offer a partial solution to current (2016) and future water challenges. In support of the National Water Census, the U.S. Geological Survey has completed a BGW assessment to gain a better understanding of the

Selected chemicals, solids, and microorganisms that are used in agriculture or produced as by-products of agriculture in the United States as of 2009
This data set brings together and categorizes many of the chemicals, solids, and microorganisms that are used in agriculture or produced as by-products of agriculture in the United States (as of 2009). Each entry in the data set includes the name, Chemical Abstracts Service Registry Number, purpose(s) in agriculture, and a reference. For pesticides and their degradates, the pesticidal use, parent
Summary of Total Mercury Concentrations in Dragonfly Larvae, Western Mosquitofish, and Tree Swallow Eggs Collected from Cosumnes River Preserve 2011 2013
The Cosumnes River Preserve in the Californias Central Valley contains a mosaic of managed wetlands where conditions may promote high levels of methylmercury bioaccumulation. In order to document potential environmental health risk in these wetlands due to mercury, we analyzed dragonfly larvae, western mosquitofish, and tree swallow eggs collected from wetlands and rice fields of the Preserve from
Coefficient-based consistent mapping of imperviousness in the conterminous U.S. at 60-m resolution for 1974, 1982, 1992, 2002, and 2012
Anthropogenic impervious surfaces affect hydrology, water quality, and ecological health and are widely studied. Previous studies have been limited, however, by a lack of consistent representation of imperviousness nationally as a time series prior to 2001. This product presents estimated imperviousness at 60-meter spatial resolution, for the time periods 1974, 1982, 1992, 2002, and 2012. The mapp
Conterminous U.S. mapping of household income at the block group scale adjusted for cost-of-living for the period 2013-2014
Household income is a potential predictor for a number of environmental influences, for example, application of urban pesticides. This product is a U.S. conterminous mapping of block group income derived from the 2010-2014 Census American Community Survey (ACS), adjusted by a 2013 county-level Cost-of-Living index obtained from the Council for Community and Economic Research. The resultant raster
