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...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
