Target Completion Date: February 22, 2021 Environment, Planning, and Economics
The James Spinymussel (JSM) is an endangered freshwater mussel endemic to aquatic habitats in non-tidal streams of Virginia’s James River basin. Federal law requires VDOT to conduct biological surveys of the JSM before initiating projects. These conventional surveys are relatively costly and require a high degree of technical expertise.. Environmental DNA (eDNA) is a genetic technique that may be used to locate, monitor, and survey the status of JSMs. Previous work developed protocols that were at least as accurate as physical sampling for the detection of JSMs within inpidual stream reaches. This project will focus on extending the findings of the previous study by (1) developing the lower boundaries of detection for template DNA concentration, (2) developing protocols to overcome latent inhibition of molecular genetic reactions, and (3) increasing the precision of using down-stream sampling analyses to determine population information.
