This data was collected by the US Fish and Wildlife Service to see if environmental DNA (eDNA) varied across pools and within pools in the Illinois River basin. The data was collected in 2015 from three different habitat types: shoreline, main channel, and bays. The resulting data were then analyzed using an occupancy model.

This data release documents specificity of quantitative polymerase chain reaction (qPCR) assays to detect environmental DNA (eDNA) from tilapia, western mosquito fish and guppies. These assays provide new tools for resource managers to monitor effectiveness of management efforts to remove invasive fish from anchialine pools in Hawaii and to also survey pools for presence and absence of invasive fish. The lab work was conducted during 2019-2022.
The data support a study that describes the development and validation of a primer and probe based quantitative PCR (qPCR) assay for use with environmental DNA to detect Northwest salamander (Ambystoma gracile), a species endemic to the temperate Pacific coastal region of North America. The metadata includes qPCR quantification cycle (Cq) values from testing the A. gracile assay on DNA extracted from tissue samples derived from several A. gracile and closely related species and Cq values from testing the assay on environmental DNA (eDNA ) samples collected from two lakes, one containing A. gracile and one without the species.

Data describe designed environmental DNA (eDNA) experiments for the estimation of eDNA shedding rates for the spectaclecase (Cumberlandia monodonta), mucket (Actinonaias ligamentina), and fatmucket (Lampsilis siliquoidea) from water samples collected in the laboratory under differing laboratory conditions. Shedding rates were tested under variable mussel biomass, diet, and temperature. Parameters described include descriptions of laboratory collected water samples that were tested to estimate concentration of spectaclecase, mucket or fatmucket DNA qPCR results, and associated quality assurance measurements.

Water samples from the Platte River were collected and analyzed for environmental DNA (eDNA). The U.S. Geological Survey (USGS) Nebraska Water Science Center (NEWSC) collected samples monthly from November 2019 to September 2022 at the Platte River near Ashland, Nebraska (USGS: 06801000). The USGS, in cooperation with the City of Lincoln, collected these samples. Water from the Platte River was collected as a series of weighted bottle subsamples that were taken from equal width increments across the river and composited into a sterilized 1-liter bottle. An aliquot of this composited sample was extracted using a sterile syringe and then filtered by the USGS NEWSC staff using filters provided by Jonah Ventures. These...
The data support a study that surveyed the spatial distribution of Oncorhynchus mykiss and Cottus aleuticus eDNA in coastal streams of Big Sur, California, 2021-2022 following post-fire debris flows. The metadata represent qPCR quantification cycle (Cq) values for O. mykiss and C. aleuticus assays performed on water samples collected during June and July of 2021 and 2022 from the following streams: Big Creek, Mill Creek, Prewitt Creek, and Willow Creek. The metadata also includes the distance (meters) of each eDNA sample site from the stream mouth, volume of water (Liters) collected for eDNA analysis at each site, and the Y-intercept, slope, and R-squared value for each assay run.
These data include metadata and associated data files associated with the manuscript, "Economical Environmental Sampler Designs for Detecting Airborne Spread of Fungi Responsible for Rapid ʽŌhiʽa Death." These data include a total of 8 datasets used for both controlled and field studies evaluating the use of Active (with battery operated fan) and Passive (dependent on wind) USGS Environmental Samplers on Hawaii Island between 2016-2018. Samplers were operated under controlled laboratory and field conditions with a commercial sampler (Rotorod® Model 20) to compare efficacy in capturing synthetic polyethylene spheres (12 - 160 µm in diameter) and also Xyleborus spp. boring dust (frass) known to contain the fungi responsible...

The dataset is composed of four tables containing environmental DNA (eDNA) data, fish capture data, and site location information from Round Goby (Neogobius melanostomus) surveys conducted on parts of the Champlain Canal and upper Hudson River, and adjacent areas, in New York during 2022 and 2023.

This data release documents results of quantitative polymerase chain reaction (qPCR) assays to detect environmental DNA (eDNA) from tilapia, western mosquito fish and guppies in pools with known fish populations and in pre and post-treatment samples from pools that were treated with carbon dioxide gas. These assays provide new tools for resource managers to monitor effectiveness of management efforts to remove invasive fish from anchialine pools in Hawaii and to also survey pools for presence and absence of invasive fish. The lab work was conducted during 2019-2022.
Data describe a designed environmental DNA (eDNA) survey for the detection of Spectaclecase (Cumberlandia monodonta, also referred to as Margaritifera monodonta) from field collected water samples. Parameters described include the limit of detection and limit of quantification of the assay; a list of freshwater mussel species tissue samples that were used to test specificity of the assay; and field collected water samples that were tested to detect the presence of Spectaclecase DNA. Samples were collected from sites on the Big Piney River, Missouri from 2020 to 2022.

U.S. Geological Survey decision analysts and technical experts worked with managers and stakeholders to predict the consequences of alternative actions following environmental DNA detections of invasive Najas minor eDNA in Sebago Lake, Maine, USA. This dataset provides the consequence and model inputs for each of the alternative actions under different levels of uncertainty.

Abstract: Environmental DNA (eDNA) is DNA that has been released by an organism into its environment, such that the DNA can be found in air, water, or soil. In aquatic systems, eDNA has been shown to provide a sampling approach that is more sensitive for detecting target organisms faster, and less expensively than previous approaches. However, eDNA needs to be sampled in a manner that has been tested and found effective and, because single copies of target DNA are detected reliably, rigorous procedures must be designed to avoid sample contamination. Here we provide the details of a sampling protocol designed for detecting fish. This protocol, or very similar prototypes, has been used to collect data reported in...

This dataset contains raw sequence data collected from an eDNA metabarcoding project to detect freshwater mussel species across two sites in Georgia (Spring Creek and Flint River) and one drainage in Missouri (Big Piney River). The eDNA samples were collected from each stream using dead-end ultra filtration (D-HFUF) with eDNA extracted from filters. We used two previously published primer sets designed to amplify freshwater mussels, one that amplified the mitochondrial cytochrome c oxidase I (COI) region and one that amplified the NADH dehydrogenase subunit I region, with negative control and mock community samples included. Samples were individually indexed, pooled, and sequenced on an Illumina MiSeq high-throughput...
