Potential benefits: restore water quality save dwindling species from extinction early detection of invasive species as well as the detection of rare and cryptic species Advantages of eDNA o Collecting eDNA is easy. One 4-ounce water sample can capture remnant DNA from thousands of aquatic speciesTraditional bio monitoring methods scientists count individual species and their abundance at just a few sites. o This method doesnt require killing wildlife for identification. o It is labour and cost effective. This process requires just a cheap filter a syringe and vials and anyone can do it general knowledge refresher magazine subscription.
