This dataset includes quantifications of bigheaded carp DNA found in water samples collected from the Wabash River along transects at 3 sites over time. The samples were collected at 18 equidistant points in a transect across the river at each site. Samples were collected in 2013 on May 29, 30, 31, June 5, 6, 7, 8, 9, 10, 11, 16, 17, 19, 20, 21, and 22. Quantitative polymerase chain reaction (qPCR) was performed to determine the DNA concentrations in two replicates using the bigheaded carp assay defined in Merkes and others 2014.

This data set was collected to provide examples and aid in developing a standardized way of determining LOD and LOQ for eDNA assays and has 3 data files. GEDWG_LOD_DATA3.csv is raw qPCR data from multiple labs running multiple standards of known concentration for eDNA assays they regularly use. Comparison-Data.csv is the merged data output from running a generic LOD/LOQ calculator script multiple times with different LOD model settings. The generic LOD/LOQ calculator script is available at: https://github.com/cmerkes/qPCR_LOD_Calc, and details about the multiple settings used are commented in the analysis script available at: https://github.com/cmerkes/LOD_Analysis

Data is a spreadsheet of the number of copies of Zebra Mussel DNA detected and the number of positive detections for Zebra Mussel DNA from water samples collected over 6 different substrates, at 4 depths in 2 lakes. The ash-free dry weight of the mussels at each of the sites is also included for each sampling location.

These environmental DNA data and corresponding water quality data were collected and analyzed by the Fish and Wildlife Service in 2017. The samples were collected from 4 sites in pools 17 and 18 in the Upper Mississippi River on 3 sampling trips. The data was used to study occupancy modeling of eDNA data and determine optimal sampling effort required for reliable detection of invasive Bighead Carp and Silver Carp in streams with similar attributes at the Mississippi River.
Spectaclecase (Margaritifera monodonta) is a federally endangered freshwater mussel species that has experienced a 55% reduction in range (USFWS 2014) and is currently concentrated in three rivers in the Midwest of the United States (Gasconade, Meramec Rivers, MO, and St. Croix River, WI). Its preference for living under large rocks and boulders has limited detection of new populations by traditional survey methods. Environmental DNA technology has been used to detect invasive and rare species, but its use for detection of rare, benthic-dwelling species in large flowing systems has been limited. Here, we propose using environmental DNA to identify presumable sites for discovery of M. monodonta. We designed a M....
