Simultaneous species detection and discovery with environmental DNA metabarcoding: A freshwater mollusk case study.

Environmental DNA (eDNA) sampling is a powerful tool for rapidly characterizing biodiversity patterns for specious, cryptic taxa with incomplete taxonomies. One such group that are also of high conservation concern are North American freshwater gastropods. In particular, springsnails of the genus (Family: Hydrobiidae) are prevalent throughout the western United States where >140 species have been described.
