Organochlorine residues and elemental contaminants in U.S. freshwater fish, 1976-1986: National Contaminant Biomonitoring Program Organochlorine residues and elemental contaminants in U.S. freshwater fish, 1976-1986: 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 freshwater fish 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...
Fecundity of Sicklefin (Macrhybopsis meeki) and Shoal Chub (M. hyostoma) Fecundity of Sicklefin (Macrhybopsis meeki) and Shoal Chub (M. hyostoma)
Estimates of total fecundity of two Macrhybopsis species typically found in the lower Missouri river.
Chemistry data for assessment of the containment pond at Canyon Mine, Arizona 2017 Chemistry data for assessment of the containment pond at Canyon Mine, Arizona 2017
These data are comprised of measurements of elements (e.g., uranium, cobalt, nickel, copper, zinc, cadmium, lead, etc.), major anions (chloride, nitrite+nitrate as nitrogen, sulfate, etc.), dissolved organic carbon, and general water quality characteristics in Canyon Mine containment pond water, sediment, vegetation and invertebrate samples collected in calendar year 2017.
Tag retention and survival of juvenile bighead carp implanted with an acoustic tag at three temperatures Tag retention and survival of juvenile bighead carp implanted with an acoustic tag at three temperatures
Bighead carp Hypophthalmichthys nobilis and silver carp H. molitrix (together, the bigheaded carps) are considered among the most problematic of invasive fishes in North. Movement and behavior of bigheaded carps has been studied through telemetry methods although the majority of work has occurred on large, adult fish; smaller, juvenile bigheaded carps have not yet been evaluated...
Organochlorine residues in starlings (Sturnus vulgaris) from the continental United States 1974-1985: National Contaminant Biomonitoring Program 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...
Acute toxicity of sodium chloride and potassium chloride to a unionid mussel (Lampsilis siliquoidea) in water exposures-Data 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 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...
Behavioral Effects of Copper on Larval White Sturgeon 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 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...
Interior Least Tern Sandbar Nesting Habitat Measurements from Landsat TM Imagery-Data 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...
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 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...
Chemical analyses and histopathology of small rodents, vegetation, and soil collected from the Kanab North breccia pipe uranium mine in the Grand Canyon watershed 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...
