This QR project resulted in a report and a publication. The Kentucky arrow darter (Etheostoma spilotum, KAD) is a species of conservation concern due to its fragmented distribution and threats from anthropogenic stressors. In this report, I evaluate the relationship between KAD abundance and stream conductivity in the upper Kentucky River basin. Stream conductivity represents an indicator of exposure to headwater mining operations and/or shale gas development and may have direct or indirect effects on stream fish distributions. I used nonlinear regression techniques to evaluate change points and associated confidence intervals for KAD abundance related to conductivity levels. I also evaluated blackside dace (Chrosomus...

Brook trout are the only native fish from the salmon family in the southeastern United States. Despite their recreational and cultural significance, human activities, such as habitat degradation and introduction of non-native species, have led to serious declines of brook trout populations in the region. Stream temperature and flow alterations from climate change are projected to impact this cold-water species even further. Recent studies show that there is much site-to-site variation in how climate affects stream temperature and flow. Therefore, vulnerability of local trout populations to climate change also varies. Understanding local variation in climate responses across the region is critical to maintaining...

This Data Release provides records of fish species abundance collected during summer 2015 using single pass backpack electrofishing within sections of Owens Creek, Big Hunting Creek, and Blue Blazes Creek (a tributary to Big Hunting Creek) in Maryland (USA). We also provide water and air temperature data collected during at 30 minute increments summers of 2015 and 2016. Stream physical habitat data are also reported for fish sampling sites.

This study set out to answer the question: “What data and modeling frameworks are needed to provide scientists reliable, climate-informed, water temperature estimates for freshwater ecosystems that can assist watershed management decision making?” To accomplish this, the study gathered existing stream temperature data, identified data gaps, deployed stream temperature monitoring devices, and developed and tested a stream temperature model that could be regionalized across the Northeast domain. We partnered with another funded project team, led by Jana Stewart at WI USGS to collect data from over 10,000 locations across the climate science center domain. This collection effort aided in identifying data gaps where...
