Trace metals in water and biota in and near headwater streams in the Colorado Mineral Belt

This data release includes sampling location data, field-collected water chemistry data, cation and anion concentration data for water and tissues of submerged aquatic vegetation, aquatic insect larvae, adult aquatic insects and riparian spiders from 35 first- and second-order sub-alpine streams that ranged over several orders of magnitude in metal concentrations but were similar in elevation, geo

Science to Inform Management of Floodplain Conservation Lands on the Middle Mississippi River

Within large-river ecosystems, floodplains serve a variety of important ecological functions. A recent survey of 80 managers of floodplain conservation lands along the Upper and Middle Mississippi and Lower Missouri Rivers in the central United States found that the most critical information needed to improve floodplain management centered on metrics for characterizing depth, extent, frequency, du

Metabarcoding data from freshwater mussel eDNA collected in Clinch River, Virginia 2017

Data from metabarcoding assays to detect a suite of mussel species using mitochondrial DNA regions of the cytochrome c oxidase subunit I (COI) and NADH dehydrogenase subunit (ND1) genes sequences.

2017 Yellowstone River Dye-Trace Experiment

Data consist of geolocation, temperature, turbidity, time, and dye concentrations collected at four downstream locations from Rhodamine WT dye injection point on Yellowstone River in June 2017

Aquatic Macroinvertebrate Data Collected from Kansas City Metro Area Streams, 2011-2013

During Fall 2011 (Oct. 3-6, 2011), Spring 2012 (March 26-28, 2012), Spring 2013 (April 28-30, 2013), and Fall 2013 (Oct. 22-25, 2013), the USGS-CERC (Barry Poulton) and the Kansas City Water Services Dept. (Jing Tao) sampled stream-dwelling aquatic macroinvertebrate communities in nine watersheds within the non-connected stormwater management region in Kansas City, Missouri, utilizing the Missouri

Mucket eDNA detection in Wallen's Bend, Clinch river, Tennessee, September 2019

The data describe the technical performance of a designed qPCR assay for the detection of mucket (Actinonaias ligamentina) eDNA from field collected water samples. Parameters described include the sequences of the primers and probes used; the limit of detection and limit of quantification for the assay; a list of freshwater mussels species that were used to test specificity of the assay; and in si

Swimming speeds of grass carp in response to turbulence

In this experimental series we studied the swimming capabilities and response of grass carp (Ctenopharyngodon idella) larvae to flow turbulence in a laboratory flume. We compared three different experimental configurations, representing in-stream obstructions commonly found in natural streams (e.g. a gravel bump, a single vertical cylinder, and patches of submerged rigid vegetation). Grass carp la

Relative tolerance of different life stages of Rio Grande silvery minnow to elevated water temperatures

Response of Rio Grande silvery minnow from three year classes and four age groups to one of seven temperatures (nominally; 28.5, 30.0, 31.5, 33.0, 34.5, 36.0, and 37.5ºC) and a control (25ºC) for 96 hours under static conditions

Chemical and biological exposure bioassay data from sediment collected within the Grand Calumet River, Indiana, USA

The Grand Calumet River (GCR), located in northern Indiana, is contaminated due to a wide range of historical industrial activities. Short-term and long-term sediment exposure bioassays with the amphipod Hyalella azteca, the midge Chironomus dilutus, and the mussel Lampsilis siliquoidea were conducted with samples collected in 2013, 2015, and 2017, from up to 26 sites, including both remediated, n

Burrowing behavior of freshwater mussels

Data include burrowing behavior of juvenile freshwater mussels (Lampsilis siliquoidea); Villosa constricta; Megalonaias nervosa; Villosa iris; Lampsilis powellii; and Anodonta oregonensis) in three types of sediment [a sand/silt/clay mixture (49 percent sand) with a total organic carbon (TOC) content of about 3 percent obtained from northeastern Minnesota, a predominantly fine sand (82 percent san

Physiological and behavioral responses of bighead and silver carp to chemicals associated with common carp sex pheromones

This dataset contains a combination of physiological and behavioral approaches for characterizing the response of bighead and silver carp to potentially attractive chemicals associated with sex pheromones identified in common carp. The dataset contains eight tables: 1) EOG responses from untreated and masculinized silver carp to prostaglandins, 2) mixture discrimination indices of the prostaglandi

Legacy and emerging contaminants in the Chesapeake Bay watershed as measured using passive samplers - 2005 to 2013

Legacy and emerging contaminants were measured in streams and rivers in the District of Columbia and the states of Maryland, Pennsylvania, Virginia, and West Virginia of the Chesapeake Bay watershed between 2005 and 2013. Passive sampling devices, SPMDs and POCIS, were used to sample these waterbodies, providing a time-integrated concentration of contaminants that are potentially bioavailable to n
