Environmental DNA (eDNA)
Environmental DNA (eDNA) refers to genetic material collected from the environment, such as soil, water, or air, rather than directly from organisms. When plants, animals, or microorganisms shed cells, tissues, or waste, they release DNA into their surroundings. Researchers can analyze this eDNA to identify species present in an area, monitor biodiversity, or assess ecosystem health. This method is non-invasive and allows for studying elusive or endangered species, making it a valuable tool in conservation and ecological studies.

Environmental DNA (eDNA) refers to genetic material collected from environmental samples, such as soil, water, or air, rather than directly from an organism. As creatures shed skin, scales, or waste, their DNA enters the environment. Scientists analyze eDNA to detect the presence of species in a given area, helping to monitor biodiversity and assess ecosystem health. This non-invasive method allows researchers to study hard-to-find or endangered species without extensive fieldwork, making it a valuable tool for conservation and ecological research.
