Making environmental DNA (eDNA) biodiversity records globally accessible

Abstract

Abstract Environmental DNA (eDNA) metabarcoding, where specific DNA markers (barcodes) are purified from the environment, sequenced, and used to identify organisms, is revolutionizing biodiversity science. Researchers, industry, and governments are increasingly incorporating eDNA surveys into their toolkits for biomonitoring because of their high accuracy, taxonomically holistic lens, and ease of deployment. Yet, the full value of this rich and revolutionary technique is not being realized because eDNA data are rarely maintained in consistent formats or on open platforms that facilitate easy re‐use or integration with other data layers. Here, we discuss opportunities to improve the accessibility and “FAIRness” of eDNA records with the aim to maximize the value of this remarkable source of information on environmental state and change.
