In times of exacerbating biodiversity loss, reliable data on species occurrence are essential. Environmental DNA (eDNA) – DNA released from organisms into the water – is increasingly used to detect fishes in biodiversity monitoring campaigns. However, eDNA turns out to be capable of providing much more than fish occurrence data, including information on other vertebrates. A study, published in the open-access journal Metabarcoding and Metagenomics, demonstrates how comprehensively vertebrate diversity can be assessed at no additional costs.
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 […]
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 […]
