USGS EcoDrought Stream Discharge, Gage Height, and Water Temperature Data in Massachusetts
The USGS Water Mission Area (WMA) - Ecosystems Mission Area (EMA) EcoDrought project is comprised of interdisciplinary teams in five pilot regions across the country. The over-arching project goal is to measure streamflow in headwater streams and to relate flow variation to stream fish population dynamics. In the northeast, the New England Water Science Center (NewEngWSC) partnered with the fish
Stream temperature observations during summer 2021 for sites in the Sleepy Creek watershed, West Virginia
This Data Release contains stream temperature observations for 10 sites in the Sleepy Creek Watershed (West Virginia) during summer 2021. Data were collected using Onset ProV2 temperature gages within perforated PVC cases attached to stream substrates with rebar. Temperature gages were deployed and retrieved by volunteers with the Sleepy Creek Watershed Association. Temperature records are provide
Water and air temperature data from Shenandoah Valley streams, Virginia (2017)
This Data Release provides hourly records of air and water temperature within 5 watersheds (Beaver Creek, Dry River, Mossy Creek, Passage Creek & Spout Run) in the Shenandoah Valley, VA in the summer of 2017. Data loggers were deployed and retrieved by Trout Unlimited personnel and volunteers.
Landscape and stocking effects on population genetics of Tennessee Brook Trout
Throughout their range, Brook Trout (Salvelinus fontinalis) occupy thousands of disjunct drainages with varying levels of disturbance, which presents substantial challenges for conservation. Within the southern Appalachian Mountains, fragmentation and genetic drift have been identified as key threats to the genetic diversity of the Brook Trout populations. In addition, extensive historic stocking
Comparative morphology of freshwater sculpin inhabiting different environmental conditions in the Chesapeake Bay headwaters
We compared body morphology of two freshwater sculpin taxa that inhabit distinct environmental conditions in the Chesapeake Bay watershed of eastern North America: Potomac sculpin (C. girardi, Robins; PS) and checkered sculpin (C. sp. cf. girardi; CS). Both taxa are endemic to the study area, but PS are more broadly distributed than CS which are limited to karst groundwater-dominated streams in th
Assessing native fish restoration potential in Catoctin Mountain Park
Biological conservation is a fundamental purpose of the National Park system, and Catoctin Mountain Park (CATO) supports high-quality habitat for native fishes in the headwaters of the Chesapeake Bay watershed in eastern North America. However, native Blue Ridge sculpin (Cottus caeruleomentum) have been extirpated in Big Hunting Creek above Cunningham Falls in CATO. Prior research indicates that i
Modeling occupancy of rare stream fish species in the upper Cumberland and Kentucky River Basins
Biological conservation often requires an understanding of how environmental conditions affect species occurrence and detection probabilities. We used a hierarchical framework to evaluate these effects for several Appalachian stream fish species of conservation concern: Chrosomus cumberlandensis (BSD; blackside dace), Etheostoma sagitta (CAD; Cumberland arrow darter), and Etheostoma spilotum (KAD;
Comparison of underwater video with electrofishing and dive‐counts for stream fish abundance estimation
Advances in video technology enable new strategies for stream fish research. We compared juvenile (age‐0) and adult (age 1+) Brook Trout Salvelinus fontinalis abundance estimates from underwater video with backpack electrofishing and dive‐count methods across a series of stream pools in Shenandoah National Park, Virginia (n = 41). Video methods estimated greater mean abundance of adult trout than
