Surface Materials Data from Breccia-Pipe Uranium Mine and Reference Sites, Arizona, USA

This data release includes elemental analysis of soil samples collected at breccia-pipe uranium mines, at one undeveloped breccia-pipe uranium deposit, and at a reference site in northern Arizona. Samples were collected near the Arizona 1, Canyon, Kanab North, and Pinenut uranium mines, over the EZ2 breccia-pipe uranium deposit, and at the Little Robinson Tank reference site. Samples were...

Absorption, distribution, metabolism, and elimination of seed-treatment pesticides following the dosing of Japanese quail (Coturnix japonica)

Japanese quail (Coturnix japonica) were orally dosed with pesticide-treated or control-untreated wheat seeds. Pesticide treated wheat seeds were analytically verified for active ingredients of imidacloprid, metalaxyl, tebuconazole, and fludioxonil. Pesticide and metabolite residues were measured in plasma, liver, brain, kidney, muscle, and excreta of exposed and control birds. Samples were...

Spatio-temporal distribution models for dabbling duck species across the continental United States

These data describe the spatio-temporal distribution of dabbling duck species across the continental United States during four biologically relevant seasons. This dataset contains two types of distribution models: (1) probability of presence, and (2) abundance. The model type, species, and season depicted in a raster are defined in the file name. File names begin with either abun (...

Histopathology of American kestrels (Falco sparverius) sequentially exposed to first and second generation anticoagulant rodenticides

This dataset describes histopathological changes in liver, kidney, heart, skeletal muscle and intestine of captive American kestrels sequentially exposed to first and second generation anticoagulant rodenticides (FGAR and SGAR). The goal of the study was to determine the toxicity of sequential exposure to anticoagulant rodenticides (ARs) by evaluating FGAR-FGAR exposure (7 day chlorophacinone...

Histopathological assessment of the digestive gland of a freshwater snail (Lymnaea stagnalis) exposed to uranium

This dataset consists of measurements of the digestive gland in the freshwater snail Lymnaea stagnalis orally exposed to uranium. The objective of the study was to assess the morphological effects of uranium on the snail digestive gland by light microscopy. Laboratory-cultured L stagnalis were exposed to either synthetic or natural solid phases of uranium and a subset (6 controls and 6...

Histopathology of zebra finches (Taeniopygia guttata) exposed to 15mg/kg, 30mg/kg, or 60mg/kg clothianidin in seed or water

This dataset describes histopathological changes in liver, kidney, gonad, and spleen of zebra finches exposed to 15mg/kg, 30mg/kg or 60mg/kg clothianidin (CTD) in water or on millet seed. 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...

Data for Understanding the captivity effect on invertebrate communities transplanted into an experimental stream laboratory

Little is known about how design and testing methodologies affect the macroinvertebrate communities that are held captive in mesocosms. To address this gap, we conducted a 32-day test to determine how seeded invertebrate communities changed once removed from the natural stream and introduced to the laboratory. We evaluated larvae survival and adult emergence in controls from 4 subsequent...

Minnesota Mine Shaft Tracer Data, Lion Creek Watershed near Empire, Colorado, July-November, 2017

On July 26, 2017, a solution containing approximately 200 kilograms of dissolved sodium bromide was added to the the flooded underground shaft of the Minnesota Mine, near Empire, Colorado. This addition was conducted as part of an effort to determine the degree to which the mine shaft is hydrologically connected to a series of downgradient seeps and springs.

Nitrapyrin, 6-CPA, and herbicide concentrations in agricultural soils, subsurface drains, and corresponding streams in the Midwestern US

Nitrapyrin is a nitrification inhibitor that is co-applied with N-fertilizer in agroecosystems. Over the course of one year (March 2016 to June 2017), 192 water samples from seven streams across Iowa and Illinois were analyzed for nitrapyrin, its degradate 6-chloropicolinic acid (6-CPA), and three widely used herbicides acetochlor, atrazine, and metolachlor. Additional environmental samples...
