Improving Whole Biodiversity Monitoring and Discovery With Environmental DNA Metagenomics
Molecular Ecology Resources, Volume 25, Issue 6, August 2025.ABSTRACT Environmental DNA (eDNA) metagenomics sequences all DNA molecules present in environmental samples and has the potential of identifying virtually any organism from which they are derived. However, due to unacceptable levels of false positives and negatives, this approach is underexplored as a tool for biodiversity monitoring across the tree of
