A Box Fan Pulled Wildlife Out of the Air
Two Danish field studies recovered local animal DNA from airborne particles and refined a low-cost biodiversity sampling method.
Summary
Two Danish field studies recovered local animal DNA from airborne particles and refined a low-cost biodiversity sampling method.
University of Copenhagen researchers hung fan-driven filter boxes in three Danish nature areas and sequenced the animal DNA collected from the air. Across the two studies, the method detected dozens of local bird and mammal species, including European bison, owls and white-tailed eagles, while tests of filters, airflow, storage and sampling time improved reliability. The researchers still need to determine how far and how long airborne DNA travels, so a detection indicates local presence rather than an exact animal location.
