Recent study conducted at a UK fishery farm provides new evidence that DNA from water samples can accurately determine fish abundance and biomass Organisms excrete DNA in their surroundings through metabolic waste, sloughed skin cells or gametes, and this genetic material is referred to as environmental DNA (eDNA). As eDNA can be collected directly from […]
Metabarcoding allows scientists to extract DNA from the environment, in order to rapidly detect species inhabiting a particular habitat. While the method is a great tool that facilitates conservation activities, few studies have looked into its applicability in monitoring species’ populations and their genetic diversity, which could actually be critical to assess negative trends early on. The potential of the method is confirmed in a new study, published in the peer-reviewed scholarly journal Metabarcoding & Metagenomics.
In a major pan-European study, a research team from Germany have successfully extracted environmental DNA (eDNA) from as many as 218 lakes to refute a long-year belief that vital microorganisms do not differ significantly between freshwater bodies and geographic regions the way plants and animals do. Their new-age approach to biodiversity studies resulted in the […]
