About the event
The Southern eDNA Society is presenting two talks: Lara Denis Roy will talk about:
Title: Harnessing eDNA for reef monitoring: a continental scale comparison with visual surveys in Australia Abstract: The present study aims to compare the use of eDNA against visual surveys in studying reefs and to determine the value of its application to assess ecological change in reef ecosystems at the scale of the Australian continent. It analyses reef communities through two metabarcoding assays (16S Fish and COI Leray) as well as underwater visual surveys (UVS) following the Reef Life Survey method. Water sampling and UVS were done synchronously, and across six Australian states, both during the day and at night. The sensitivity of eDNA is measured against the ‘conventional’ UVS method for biomonitoring, in terms of taxonomic composition and species detectability at a local and continental scale, including for rare and threatened species.
