Watered down biodiversity: Sample type is critical in environmental DNA studies for biomonitoring

DNA-based biomonitoring relies on species-specific segments of organisms DNA for their taxonomic identification and is rapidly advancing for monitoring invertebrate communities across a variety of ecosystems. The analytical approaches taken vary from single-species detection to bulk environmental sample analysis, depending largely on the focus of data generation. However, for freshwater systems, there is often a lack of consideration as to the optimal sample type for maximising detection of macroinvertebrates.
