Environmental DNA metabarcoding for marine monitoring across ecological scales

The effective management and conservation of environments relies heavily on accurate data on biodiversity. High-throughput sequencing of environmental DNA represents one example of a novel technique that has proven valuable for marine biodiversity assessments. The research presented in this thesis explored the utility of eDNA metabarcoding for marine monitoring across ecological scales in northwest Australia. This thesis adds to growing evidence of the value of eDNA-based techniques for generating biodiversity data and showcases the utility of eDNA in answering ecological questions at the scale of whole reef ecosystems, coral communities, megafauna populations, and commercial fisheries species.
