GEANS paper on detection of macrobenthos species with metabarcoding: bulk DNA vs. eDNA from samples in ethanol preservative
DNA extraction of the mixed sample still yields better results than just using the ethanol in which the sample was stored. The accurate identification of a species is dependent on its size and the presence of chitine or CaCO3. The choice of primer set also had a huge impact on the result.
