Landscape modeling of Kentucky arrow darter (Etheostoma sagitta spilotum) occurrence and response to water quality parameters 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...

Timed search (qualitative) surveys were conducted in consecutive ~200 meter sections of river in 2006 and 2007; a subset of these sections were re-surveyed qualitatively in 2009. The number of mussels of each species and associated search time were recorded for each survey section to determine a catch per unit effort (CPUE; number of individuals found per person hour). Within the 2009 qualitatively surveyed areas, ten ~200 meter sections of stream were selected in which to conduct quantitative surveys to estimate mussel abundance. Quantitative survey methods...

The general objectives to this study were threefold, as follows: 1. To determine the environmental presence and abundance of Bden in headwater regions of river systems in the Southeastern United States through water samples evaluated for the presence of environmental DNA (eDNA). 2. To determine the presence of Bden infection in fauna of these headwater regions, including larval and adult amphibians as well as other potential reservoirs of infection. 3. To determine whether any association exists between water flow rate and associated stream parameters in headwater systems versus the presence/prevalence of Bden both in the environment and infecting amphibian host...

Data includes source location, species, morphometric data, and IAV matrix gene detection status for the bivalve samples collected and analyzed in the associated study.
