Data

These data are comprised of measurements of elements (e.g., uranium, cobalt, nickel, copper, zinc, cadmium, lead, etc.) in Canyon Mine containment pond samples collected in calendar years 2017 and 2018.

This data set includes geospatial data and tables providing location, environmental, and vegetation data collected in 2017 and 2018 at the Little Saint Francis River chat pile restoration site, Fredericktown, Madison County, Missouri. Restoration actions are being implemeneted as part of the settlement for the Madison County Mines Superfund site to compensate the public for losses of natural resou

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, freshwater fish w

Estimates of total fecundity of two Macrhybopsis species typically found in the lower Missouri river.

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.

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. Reductions in t

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.

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

Attributes regarding the effects of copper exposure on larval white sturgeon swimming and feeding behaviors and time to response.

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

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
