Optimizing eDNA Replication for Standardized Application in Lotic Systems in Aotearoa, New Zealand

Environmental DNA, Volume 6, Issue 5, September–October 2024.
The objective of this study was to optimize eDNA sample replication for the consistent characterization of freshwater fish and aquatic macroinvertebrate communities in flowing New Zealand waters, and ultimately, to inform the development of robust national monitoring standards. Results indicated that six replicates were needed to consistently detect 89.
