What is eDNA?

Environmental DNA (eDNA) refers to genetic material obtained directly from environmental samples such as soil, sediment, water, or air, rather than from isolated organisms. eDNA analysis is commonly used for biodiversity assessment, species detection (including rare or invasive species), monitoring ecosystem health, and studying population genetics. It involves collecting environmental samples, extracting DNA, and then using techniques like PCR or DNA sequencing to identify the organisms that shed the DNA into the environment.
