eDNA: How Scientists See Hidden Animals

Environmental DNA (eDNA) is a powerful tool for studying and monitoring species by analyzing DNA fragments left in the environment. It allows researchers to detect species presence and distribution, even in challenging conditions. Despite challenges like DNA decay and environmental factors, eDNA has been successfully used in various studies, such as tracking invasive bluegill sunfish in Japan and endangered wood turtles in Virginia. eDNA also reveals unexpected findings, like detecting rare marine species. Its applications extend to monitoring diverse species, offering a cost-effective and efficient method for conservation efforts.
