A long-term, multiseason, fish egg sampling program is conducted annually on the Detroit, Saint Clair, and Saint Marys rivers to identify where productive fish spawning habitat currently exists. Egg mats were placed on the river bottom during the spring and fall at historic spawning areas, candidate fish spawning habitat restoration sites, and completed spawning habitat restoration sites throughout the rivers. Widespread evidence was found of lithophilic spawning by numerous native fish species, including walleye (Sander vitreus), lake whitefish (Coregonus clupeaformis), lake sturgeon (Acipenser fulvescens), suckers (Catostomidae spp.), and trout-perch (Percopsis omiscomaycus). The data describe the number, density,...

The satellite data consist of 9,253 estimated locations of 21 golden eagles (Aquila chrysaetos) that were satellite-tagged in either east-central Idaho (Salmon, Idaho) or southwestern Idaho (Snake River National Conservation Area) and tracked between 1993 and 1997 via the Argos satellite system. The raw eagle tracking data provided by Argos were filtered one time using a version of the Douglas Argos-Filter Algorithm and converted into XLS spreadsheet form. This preservation project preserved the geospatial and satellite information from the XLS spreadsheet and released it in shapefile format (Satellite_Data.shp) and CSV format (Satellite_Data.csv). Each tagged bird in this dataset has a unique PTT number that is...

Nineteen sediment cores were collected from five salt marshes on the northern shore of Cape Cod where previously restricted tidal exchange was restored to part of the marshes. Cores were collected in duplicate from two locations within each marsh complex: one upstream and one downstream from the former tidal restriction (typically caused by an undersized culvert or a berm). The unaltered, natural downstream sites provide a comparison against the historically restricted upstream sites. The sampled cores represent a chronosequence of restoration occurring between 2001–10. Collected cores were up to 168 cm in length with dry bulk density ranging from 0.04 to 2.62 grams per cubic centimeter and carbon content 0.12 %...

Stream water chemistry and benthic macroinvertebrate data collected in the North Fork of Clear Creek and Clear Creek, CO, USA before and after the diversion and treatment of acid mine drainage by a high-density sludge lime process water treatment plant. Stream water chemistry and benthic macroinvertebrate samples were collected from November 2011 through October 2019 at 6 sites located above and below the North Clear Creek Water Treatment Plant (NCCWTP). The NCCWTP became fully operational in September 2017. Measured water chemistry included pH, conductivity, alkalinity, ferrous iron, total and dissolved concentrations of metals and major geochemical cations, and dissolved organic carbon. Replicate (n=5) benthic...
Data set contains water quality measurements and survival of fathead minnow from in situ and laboratory bioassay exposures to wastewater from a spill on Blacktail Creek, North Dakota, USA
Dataset consists of 4-day, 14-day, and full life responses of laboratory cultured mayflies (Neocloeon triangulifer) to nickel and zinc exposure. Responses were measured as mortality, body weight, development time, and reproduction. Water quality and analytical chemistry results associated with toxicity data are included. Additional data included are results of experiments assessing proportion of dissolved metal to nominal metal as influenced by the ratio of diatom diet dry mass present per volume of water.
Dataset consists of 4, 7, 10, and 14-day responses of laboratory cultured mayflies (Neocloeon triangulifer) to sodium chloride exposure under different test condition scenarios. Responses were measured as mortality and growth (length). Water quality and analytical chemistry results associated with toxicity data are included. Experiments included 1) testing the influence of organism age on mortality and growth in 7-day tests, 2) testing the influence of test duration on mortality and growth, 3) testing the influence of temperature on mortality and growth, 4) testing the influence of nutrient amendments to mayfly test dilution water on mortality and growth
Biological endpoints for three focal test species [Daphnia magna (mortality), Psuedacris maculata (mortality, growth, and development), and Lemna gibba (growth)] in response to exposure to reconstituted or field-collected water under laboratory conditions. Field-collected waters were collected from wetlands within the Prairie Pothole Region (PPR) of the United States. Reconstituted water was mixed to mimic some chemistry of surface water from brine contaminated PPR wetlands. Also included are water quality and chemical concentration data from all assays.
Data contain zero-crossing, frequency acoustic detector locations, date to hour, species of bats recorded and identified and various wind and precipitation values associated with either day or hour for ridges,sideslopes and valleys at 5 locations in western Virginia's Appalachian Mountains.

In order to estimate the costs of chemical control of non-indigenous crayfish versus the cost of manual inspection of fish hatchery shipments a cost analysis was performed. The data includes ranking the likelihood of missing non-indigenous crayfish and effects on fish of handling during manual searches and the effects on fish during chemical exposure. The data also includes estimates of the time, staff, and salary requirements and cost of materials for each approach.
A piscicide delivery method was designed to selectively target black carp Mylopharyngodon piceus, an invasive species in North America which possesses specially adapted pharyngeal teeth for crushing mollusk prey. Bait was prepared by attaching a glass vial containing toxicant (antimycin A) to the exterior of Corbicula fluminea clam valve. The vial was designed to break by the force exerted from the fish’s (550 millimeter total length) pharyngeal teeth when the fish attempted to crush and consume the clam. Suitable vial size was tested for encapsulating piscicide and two attachment materials, aquarium epoxy and ultraviolet light (UV) cured attachment material. Toxic baits consisting of antimycin A piscicide were...
This data release includes physical and chemical characteristics of field collected samples from streams and rivers within the Tri-State Mining District (TSMD) as well as toxicity endpoints from chronic water-only and sediment laboratory exposures including survival and growth of the mussel Lampsilis siliquoidea; survival, growth, and reproduction of the amphipod Hyalella azteca; metal concentrations, and various water quality parameters collected during the toxicity studies. Mining in the Tri-State Mining District took place over a large geographic area, with mining taking place in the three states of Missouri, Kansas, and Oklahoma.
This dataset reports select histopathological changes in liver, kidney, gonad, spleen, brain, heart, skeletal muscle, lung, or adrenal gland of zebra finches exposed to 15mg/kg, 18mg/kg, 30mg/kg, 60mg/kg, 75mg/kg, 125mg/kg, or 250mg/kg clothianidin (CTD) (with controls) by gavage, in water, or on millet seed either as a single dose or for 7 days. The goal of the project is to develop a subacute neonicotinoid toxicity model using zebra finches as a model passerine. We have completed two acute toxicity trials using CTD insecticide. Based on these studies, we estimate the no observable effect level (NOAEL) and the lowest observable effect level (LOAEL) for CTD in zebra finches to be 15 and 30 mg/kg body weight, respectively,...

Of the 21 golden eagles satellite-tagged in Salmon, Idaho and Snake River National Conservation Area, 10 were also radio-tagged with tail-mounted very high frequency (VHF) transmitters to allow for behavioral observations between 1993 and 1994. The observed data were originally processed as a DIF file. The Data at Risk preservation project transformed the original DIF file data into CSV format and created a shapefile from the geospatial points. The observed data shapefile (Observed_Data.shp) provides the 682 estimated locations of the golden eagles and all behavioral observations taken in the field. The information provided in the Observed dataset can be related to the other two datasets via each bird’s unique PTT...

Approximately 43 million people (about 14 percent of the U.S. population) rely on domestic wells as their source of drinking water. Unlike community water systems, which are regulated by the Safe Drinking Water Act, there is no comprehensive national program to ensure that the water is tested to ensure that is it safe to drink. A study published in 2009 from the National Water-Quality Assessment Program of the U.S. Geological Survey that assessed water-quality conditions from 2,100 domestic wells within 48 states reported that more than one in five (23 percent) of the sampled wells contained one or more contaminants at a concentration greater than a human-health benchmark. In addition, there are many activities,...
