Data describe a designed environmental DNA (eDNA) survey for the detection of longnose darter (Percina nasuta) in field collected water samples. Parameters described include the limit of detection and limit of quantification of the assay; a list of freshwater fish 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 longnose darter DNA. Samples were collected from sites on the St. Francis river, Missouri in 2018.

These data were compiled as part of a larger study to evaluate post-stocking survival of hatchery-reared Roundtail Chub. We conducted a two year study (Dec. 2015 – Mar. 2017) in the upper Verde River at the Burnt Ranch stocking location near Paulden, Arizona. Young of year Roundtail Chub were acquired from the Arizona Research and Conservation Center in Cornville, Arizona. Passive integrated transponder (PIT) tags (BioMark, 12.5 mm 134.2 kHz FDX) were implanted into Roundtail Chub each year (n = 333, Year 1; n = 2177, Year 2) prior to stocking. Each year, fish were measured (total length, TL, mm) before release (reflected in Pre-Stocking data table). We used two methods to recapture stocked fish, one passive and...

While small unmanned aerial systems (UAS) present a unique opportunity to survey avian populations while limiting disturbance, relatively little is known about how this method compares with more traditional approaches. In this study we compared population estimates of a mixed-species egret colony in the Chesapeake Bay (Maryland, USA) derived from UAS photo counts, flush counts, flight-line surveys, and in-colony nest counts along with the time required to derive an estimate via each approach. These data support a larger USGS manuscript.

Community composition data from multi-pass electrofishing surveys for assessing fish populations in headwater streams of the Adirondack Mountains, New York, USA. Each row represents one individual fish. This spreadsheet contains 11 columns. The first 7 columns describe the data (year collected, local site ID, stream name, latitude, longitude, USGS site number, and electrofishing pass number) and the remaining 4 columns describe each individual fish (common name, scientific name, total length (mm) and weight (g)). These data support the following publication: Baldigo, B.P., Sporn, L.A., George, S.D., and Ball, Jacob, 2017. Efficacy of environmental DNA to detect and quantify Brook Trout Salvelinus fontinalis, populations...
