Cyanobacterial toxin effects on inflammatory response of human toll-like receptors (TLRs)

Various stressors including temperature, environmental chemicals and toxins can have profound impacts on immunity to pathogens. It is believed that increased eutrophication near rivers and lakes coupled with climate change are predicted to lead to increased algal blooms. Currently, the effects of cyanobacterial toxins on disease resistance in mammals is a largely unexplored area of research. Impor

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.

Data on blood cells of the collector urchin, Tripneustes gratilla

Echinoderms such as urchins are important in marine ecosystems, particularly as grazers, and unhealthy urchins can have important ecological implications. For instance, unexplained mortalities of Diadema sp. in the Caribbean were followed by algal overgrowth and subsequent collapse of coral reef ecosystems. Unfortunately few tools exist to evaluate echinoderm health making management of mortalitie

Water Quality Data from Select Spring and Stream Sites and Water and Sediment Quality Data from the Colorado River and Major Tributaries in Grand Canyon, Northern Arizona (ver. 2.0, April 2024)

This USGS Data Release represents water and sediment quality data collected in the Grand Canyon region of northern Arizona. There are 4 separate datasets associated with this Data Release: Water quality data from major Colorado River tributary monitoring sites in and near Grand Canyon from 2015 through 2022. Sediment quality data from the Colorado River and major tributary monitoring sites in an

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

Hydrologic reconnaissance to identify areas of emergent groundwater, Mineral Creek, near Silverton, Colorado, June 2020

Hydrologic reconnaissance of Mineral Creek near Silverton, Colo., was conducted from June 25-27, 2020. Both banks of Mineral Creek and the adjacent hillsides were walked, starting near the ghost town of Chattanooga and proceeding downstream to the confluence of Mineral Creek with the Middle Fork of Mineral Creek. The purpose of this reconnaissance was to identify areas of emergent groundwater on

Skin mycobiomes of eastern North American bats

North American bats have experienced catastrophic population declines from white-nose syndrome (WNS), a fungal disease caused by Pseudogymnoascus destructans (Pd). Although Pd can infect many hibernating bat species, population-level impacts of WNS vary by host species. Microbial skin assemblages, including the fungal component (mycobiome), can influence host resistance to infectious diseases; how

Mineralogical analyses of drill core samples from the Canyon uranium-copper deposit, a solution-collapse breccia pipe, Grand Canyon area, Coconino County, Arizona, USA

This data release compiles the X-ray diffraction and electron microscopy analyses of drill core samples collected by the U.S. Geological Survey that were selected to typify the uranium-copper ore bodies of the Canyon deposit. The deposit is hosted by a solution-collapse breccia pipe, in which mineralization exists from about 650 to 2,100 ft (200 to 640 m) below the surface (Mathisen and others, 20

Bird Behavior and Mortality in Relation to Power Lines in Prairie Habitats, North Dakota, 1981to1982

A biologist and field crew from Northern Prairie Wildlife Research Center observed bird flights at 7study sites, twice weekly during two spring and two fall migration periods between April 3, 1981 and May 20, 1982. Study sites were located in south-central North Dakota in Barnes, Kidder, and Stutsman counties. The database includes flight observation's of bird species in the vicinity of power line

Whooping crane migration habitat selection data and distance to wind-energy infrastructure, 2010-2016

These data were developed to support an effort to understand how whooping cranes select stopover habitat in the presence of wind-energy infrastructure. Location and associated data came from whooping cranes from the Aransas-Wood Buffalo Population, 2010-2016. We marked a sample of 57 whooping cranes with leg-mounted transmitters that acquired locations via the global positioning system (GPS) netwo

Effects of early life stage exposure of largemouth bass to atrazine or a model estrogen (17a-ethinylestradiol)

Largemouth base histological development and transcriptomic changes in gonad tissue after early life stage exposure to Atrazine (1-Chloro-3-ethylamino-5-isopropylamino-2,4,6-triazine) or the model estrogen 17a-ethinylestradiol.

Fleas collected from black-tailed prairie dog burrows in 2016 and 2017

The data are a list of the number and species of fleas that were collected from black-tailed prairie dog burrows in Montana, North Dakota, South Dakota, Colorado, and New Mexico. Fleas were collected by swabbing ~100 burrows at 3 sites at each of 6 sites. Burrows were sampled twice each summer during 2016 and 2017.
