Data

Survival, behavior, reproduction, morphometric measurements, and tissue analyses of crayfish, mussels, and fish from acute toxicity tests with pyrethroid pesticides. Exposure and recovery water quality data are also included for quality assurance purposes.

This dataset provides results for the following: (1) metals concentrations in soils surrounding breeding song bird nest sites; (2) metals concentrations in invertebrates (earthworm and grub composites) collected near nest sites; (3) metals concentrations and delta-aminolevulinic acid dehydratase (ALAD) activity in avian blood samples; and (4) metals concentrations, indicators of oxidative stress a

This data set documents results of analysis of samples collected from the Arctic National Wildlife Refuge during Summer 2019. Data tables include: 1. The numeric and alphanumeric identifiers for samples collected for this study and the dates these samples were collected; 2. Results data containing concentration values of individual polycyclic aromatic hydrocarbon compounds in sediment, soil, and v

Using juvenile individuals of 3 species of carp (Family: Cyprinidae), we tested the potential for six amino acids to elicit an extracellular electro-olfactory response within the naris using gelatin-based electrodes. The amino acids L-alanine, L-arginine, L-aspartic acid, L-asparagine, L-glutamine, and L‑glutamic acid were tested on Grass Carp (Ctenopharyngodon idella), Bighead Carp (Hypophthalmic

Data consists of dose, dose method, solvent, weight, length and survival of test species from bioassays following an Up-and-Down method conducted with Ziram.

The study was designed to assess the strength of the innate linkage of substrate and food in foraging by early juvenile Pallid and Shovelnose Sturgeon and their hybrids and adult Sicklefin and Shoal Chub. The data include information on the fish weights throughout the duration of the experiment as well as observed fish behavior data. Wet weights from fish were recorded to monitor feeding consumpti

This data set describes developmental and physiological effects observed in fathead minnow embryos that were exposed to sodium nitrate or conductivity-matched controls. Exposures were conducted in the laboratory from fertilization through 21 days post-fertilization (dpf). Nitrate doses were 0, 2, 5, 10, 25, or 100 milligrams per liter nitrate-nitrogen; conductivity controls were matched to the 10

Dataset consists of morphometric measurements from unionid Pondmussel (Ligumia subrostrata) and concentrations of four per- and polyfluoroalkyl substances (PFAS) in water and freshwater mussels collected from a 14-day accumulation and 7-day elimination study. The accumulation of four per- and polyfluoroalkyl substances (PFAS) were measured. Samples (4 replicates) were collected at 0, 4, 12, 48, 96

Dataset consists of 4-day, 14-day, and full life responses of laboratory cultured mayflies (Neocloeon triangulifer) to perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA).  Responses were measured as survival at 4 days, 14 days, pre-emergent nymph (PEN) stage, and emergence; 14-day length; number of days to PEN stage, and imago live weight.  Water quality and analytical chemistry re

The objective of this study was to evaluate the chronic toxicity of potassium  (tested as KCl) to a commonly tested unionid mussel (fatmucket, Lampsilis siliquoidea) at five water hardness levels (25, 50, 100, 200, 300 mg/L as CaCO3) representing most surface waters in the United States. Chronic 28-d potassium chloride toxicity tests were conducted with 3-week-old juvenile fatmucket using six conc

To determine the progress of restoration, insect populations were sampled at four mitigation sites using walking butterfly transects and Malaise/pitfall insect traps. The data consists of date, time, type and placement of traps, as well as number and order of species found.

Mercury is an atmospherically transported contaminant found even in relatively pristine habitats. Once accumulated at the base of the food web, mercury can move between animals that are linked trophically. Pond-breeding amphibians may be particularly important vectors of mercury flux from remote freshwater to terrestrial systems because they feed on algae and detritus as tadpoles and metamorphose
