Organochlorine residues in starlings (Sturnus vulgaris) from the continental United States 1974-1985: National Contaminant Biomonitoring Program
The National Contaminant Biomonitoring Program (NCBP), which was developed and maintained by the U.S. Fish and Wildlife Service (FWS), monitored concentrations of environmental contaminants in fish and wildlife over a period of about 20 years. Beginning in the 1960s as a component of the multi-agency National Pesticide Monitoring Program (NPMP) and continuing through the mid-1980s, fish and wildli
Acute toxicity of sodium chloride and potassium chloride to a unionid mussel (Lampsilis siliquoidea) in water exposures-Data
Attributes regarding the acute toxicity of sodium chloride (NaCl) and potassium chloride (KCl) to larvae (glochidia) or juveniles of a unionid mussel (fatmucket, Lampsilis siliquoidea) at various water hardness and in the presence of other major ions.
Survival and drifting patterns of grass carp eggs and larvae in response to interactions with flow and sediment in a laboratory flume
A series of laboratory experiments were conducted to better understand the behavior of grass carp eggs and larvae in moving water in order to develop and implement new strategies for control and prediction of their dispersal and drift at early life stages. Settling velocity and density of a representative sample of eggs were estimated, and three trials of flume experiments with different flow cond
Behavioral Effects of Copper on Larval White Sturgeon
Attributes regarding the effects of copper exposure on larval white sturgeon swimming and feeding behaviors and time to response.
Ontogenetic changes in swimming speed of silver carp, bighead carp, and grass carp larvae-Data
We measured ontogenetic changes in routine and maximum swimming speeds of bighead, grass, and silver carp larvae. Daily measurements of routine swimming speed were taken for two weeks post-hatch using a still camera and the LARVEL program, a custom image-analysis software. Larval swimming speed was calculated using larval locations in subsequent image frames and time between images. Using an end
Interior Least Tern Sandbar Nesting Habitat Measurements from Landsat TM Imagery-Data
Sandbars of large sand-bedded rivers of the Central U.S. serve important ecological functions to many species, including the endangered Interior Least Tern (Sternula antillarum) (ILT). ILT are colonial birds which feed on fish and nest primarily on riverine sandbars during their annual breeding season of approximately May through July, depending on region. During this time, ILT require bare sand o
Evaluating chronic toxicity of sodium chloride or potassium chloride to a unionid mussel (Lampsilis siliquoidea) in water exposures using standard and refined toxicity test methods
Individual measurements of toxicity and water quality data used to calculate means reported in the associated publication. The objectives of the present study were to (1) refine test conditions for improving mussel survival and growth in a long-term feeding study, (2) evaluate chronic toxicity of NaCl and KCl to fatmucket under traditional test conditions outlined in ASTM (ASTM 2017) and the refin
Chemical analyses and histopathology of small rodents, vegetation, and soil collected from the Kanab North breccia pipe uranium mine in the Grand Canyon watershed
These data are comprised of measurements of aluminum, iron, cobalt, nickel, copper, zinc, arsenic, selenium, molybdenum, silver, cadmium, thallium, lead, bismuth, thorium, uranium, and mercury in soil, vegetation, and small rodents. Gross alpha activity, gross beta activity, and radionuclide activities (isotopic U, isotopic Th) are also presented for vegetation and soil. Radioactivities for small
Results from radiochemical analyses of small rodent whole bodies collected from breccia pipe uranium mines and reference locations in the Grand Canyon watershed.
These data are comprised of measurements of gross alpha activity, gross beta activity, and radionuclide activities (isotopic U, isotopic Th, Ra-226) in small rodent bodies. Samples were collected at non-mining and U breccia pipe mining sites in various production stages, in the Grand Canyon watershed.
Chronic toxicity of 4-Nonylphenol to two unionid mussels in water-only exposures-metadata
Chronic (28-d) toxicity of 4-nonylphenol (4-NP) to two commonly tested species of mussels: fatmucket (Lampsilis siliquoidea) and rainbow mussel (Villosa iris).
Stable carbon and nitrogen isotope values in muscle tissue of bigheaded carps and native filter-feeding fish from the lower Missouri River, USA, 2005-2006
Fish muscle tissue was analyzed for stable carbon and nitrogen isotope values (delta 13C and delta 15N) for two filter-feeding fishes native to China, silver carp (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis), and three native filter-feeding fish including bigmouth buffalo (Ictiobus cyprinellus), gizzard shad (Dorosoma cepedianum) and paddlefish (Polyodon spathula) in
Organochlorine chemicals in northern cardinal eggs from suburban Washington, DC USA
Analysis of organochlorine pesticides and polychlorinated biphenyls (PCBs) in northern cardinal eggs from six neighborhoods near Washington, DC
