This review by Sahu et al. (2022) https://doi.org/10.1016/j.jnc.2022.126325 provides a timely overview of the application of environmental DNA (eDNA) as a non-invasive molecular tool for biodiversity monitoring and conservation. The authors emphasize the power of eDNA metabarcoding for detecting rare and endangered species in aquatic ecosystems, highlighting its advantages over traditional sampling methods, especially in terms of being non-destructive to both organisms and habitats. The paper effectively synthesizes global developments in eDNA research, underlining its transformative role in fisheries management and conservation biology.
