The age of eDNA: what eDNA-based monitoring can tell us

Efficient monitoring and management of species biodiversity requires sensitive and reliable detection tools. In recent years, the analyses of DNA extracted from environmental samples (eDNA) has been proposed as a highly sensitivity monitoring tool. While a large body of literature supports the higher detection sensitivity of eDNA-based monitoring, compared to conventional methods, only few examples are available in which eDNA surveys have been used to inform and support conservation efforts. During this seminar I will present the results of my PhD research, which focussed on the freshwater fish biodiversity in the Murray-Darling Basin. I will show, through some case studies, how eDNA monitoring can improve the management of both native and invasive fish species.
