Consumption rates and total mercury concentration of food items and consumers collected at six sites on the Colorado River in the Grand Canyon, USA, 2007-2009

Mercury flux and fate (whether mercury was retained in the aquatic ecosystem or exported to the riparian ecosystem via blackfly emergence) was calculated based on animal consumption rates and total mercury concentration of diet items. Consumers and their gut contents were collected at six sites on the Colorado River in the Grand Canyon. Sites ranged from 0-367 river kilometers downstream of L...

Influence of dissolved organic carbon on the acute toxicity of copper to white sturgeon (Acipenser transmontanus) and the cladoceran (Ceriodaphnia dubia)-Data

This dataset characterizes the acute toxicity of copper and zinc to white sturgeon (~30 days post hatch) and cladocerans (less thab 24 hours old) in waters with varying dissolved organic carbon (DOC) by conducting 96-hour white sturgeon and 48-hour cladoceran copper and zinc exposures in test waters with natural DOC (from pond water) at concentrations ranging from 0.5 to 5.5 mg%

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.

Acute and latent effects of zinc on two commonly tested species (Ceriodaphnia dubia and Oncorhynchus mykiss)

Data regarding the evaluation of the toxicity of zinc in 1-, 3-, 8-, 24-, and 48-hour exposures with a cladoceran (Ceriodaphnia dubia), and in 1-, 3-, 8-, 24-, and 96-hour exposures with rainbow trout (Oncorhynchus mykiss) on survival and mobility of test organisms.

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...

Amphibian Occupancy and Effects of Habitat Use on Pesticide Exposure in Iowa Wetlands

Amphibians living in agricultural areas encounter many challenges. Two factors affecting individuals in these landscapes are habitat loss and pesticides. This thesis focuses on amphibians using agricultural wetlands in Iowa, where row crops such as corn and soybeans dominate the landscape. The goal of my first study was to determine the influences of site characteristics on amphibian presence...
