Amphibian monitoring data collected from Indiana hardwood forests, 2015-2016

This data set contains information on detections of amphibians at four bottomland hardwood restoration sites in northeastern Indiana in 2015 and 2016. Amphibian communities were surveyed using four different methods - automated recording units, diurnal visual encounter surveys along transects, nocturnal transect surveys, and amphibian rapid assessments. The data set contains three tables: 1) site

NE Indiana bottomland restoration vegetation, soils and carbon data, 2015 and 2016

This data set includes tables providing location, environmental, vegetation, soils, and carbon sampling data collected in 2015 and 2016 at vegetation sampling units on restored areas and other habitats at sites in northeast Indiana, USA. "Sample_units.txt" provides location, environmental, soil physical and chemical properties for each sample location. "Subplot_ground_flora.txt" provides subplot e

Diet items consumed by wild-caught black carp (Mylopharyngodon piceus) in the U.S.

An inventory (enumeration and taxonomic identification) of diet items consumed by wild-caught black carp, based on the examination of gut contents from fish that were collected in the lower Mississippi River drainage of the U.S.

Woody species crown and vegetation community data, Palmyra Atoll, 2016

Photo-interpretation of high-resolution aerial imagery was used to delineate individual stems of select woody species and to map vegetation communities at Palmyra Atoll, USA. Imagery collected using Unoccupied Aerial Systems in October, 2016, as well as derived elevation and mosaicked orthoimagery, were used to delineate individual crowns of coconut, Pisonia and other selected woody species that c

Black carp and grass carp morphometric measurements

Black carp Mylopharyngodon piceus and grass carp Ctenopharyngodon idella are morphologically similar species imported from eastern Asia to North America as biological control organisms. Preferred identification methods are coloration and pharyngeal tooth form. Grass carp possess serrated teeth and black carp molariform teeth. Examination of pharyngeal teeth causes extensive damage to a specimen,

Toxicity of aluminum to Ceriodaphnia dubia in natural waters as affected by hardness and dissolved organic matter

Attributes regarding the influence of dissolved organic matter on chronic Al exposure and the effects on Ceriodaphnia dubia survival and reproduction.

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 assessment of the containment pond at Canyon Mine, 2017-2018

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.

Pre-restoration vegetation data, Little Saint Francis River chat pile site, Missouri, USA, 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

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, freshwater fish w

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

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.
