The DNA that living things, human and otherwise, shed into the environment is called environmental DNA (eDNA). Collecting eDNA from water to learn about the species living there has become fairly common, but until now, no one had attempted to collect animal eDNA from the air. What we wanted to know was whether we could filter eDNA from the air to track the presence of terrestrial animals, study author Elizabeth Clare, an ecologist at Queen Mary University of London, said in a video abstract for the study, published Mar. 31 in the journal PeerJ. We were interested in whether we could use this airDNA as a way to assess what species were present in a burrow or a cave where we could not easily see or capture them, she added.
