Data from: Fine-tuning biodiversity assessments: A framework to pair eDNA metabarcoding and morphological approaches

Cátia Lúcio Pereira, M. Thomas P. Gilbert, Miguel Bastos Araújo & Miguel Graça Matias
Accurate quantification of biodiversity can be demanding and expensive. Although environmental DNA (eDNA) metabarcoding can facilitate biodiversity assessments through non-invasive, cost-efficient, and rapid surveys, the approach struggles to outperform traditional morphological approaches in providing reliable quantitative estimates for surveyed species (e.g., abundance and biomass). We present an integrated methodology for improving biodiversity surveys that pairs eDNA metabarcoding with morphological data, following a series of taxonomic and geographic filters. We demonstrate its power by applying it...
