The data comes from analysing water and soil samples for hair, shed skin, mucus and - perhaps most glamorous of all - faeces.  | Fauna & Flora | Facebook

Environmental DNA (eDNA) is tiny bits of genetic material that organisms leave behind in the water, soil, and even air. eDNA gives scientists a safe and non-invasive method to learn about an environment and the organisms that live there. By studying eDNA, researchers can learn what species are present in a particular location, what the biodiversity of the area is, and if any invasive or endangered species are present. eDNA can identify these organisms and characterize their role in the area’s fo
