Comment Different communities seem to use this term in various contextes (i) e.g. an insect trap with one ore more taxa, (ii) a pooled sample from different organisms, but same taxon; There seem to be different methods used for eDNA and bulk DNA analysis

Field Value

What about a pooled sample from one single organism (different tissues), would this fall under genomic DNA or is something like "pooled genomic DNA" needed?
