Another example of the power of environmental DNA (eDNA): a positive eDNA detection led to the rediscovery of a freshwater mussel not found live in Illinois for over a century. New student-led, open access paper in Ecology with @markdavis79.bsky.social at doi.org/10.1002/ecy....
A four panel figure showing (a) a biologist wading in a turbid river with a water sample, (b) a real-time or quantitative PCR amplification plot with a positive environmental DNA detection, (c) a biologist searching concrete riprap on a river bank, and (d) two freshwater mussels that have been marked for future monitoring and recapture.
