United KingdomScientists are using environmental DNA (eDNA), found in water, soil, and air, to study biodiversity, pollution, and disease. By analyzing genetic material shed by organisms, researchers can identify species, track invasive species, and detect pathogens without directly interacting with them. Traditional methods like trapping or observation are often inefficient and stressful for animals. New sequencing techniques, such as long-read shotgun metagenomic sequencing, allow for more comprehensive analysis by reading entire DNA fragments rather than just short genetic markers. This advancement enables more accurate identification of species and their genetic characteristics, offering a non-invasive alternative to traditional ecological research.
