Abstract

Environmental DNA (eDNA) combined with quantitative PCR analysis is a fast and accurate alternative to more costly and laborious physical methods to detect the highly invasive zebra mussel (Dreissena polymorpha). We have developed, in collaboration with the managing authorities of an artificial rese...
