Explore how scientists use environmental DNA (eDNA) in a technique called DNA metabarcoding to find and track species.

--

Scientists have been staking out a forest in Montana for an animal that’s notoriously tricky to find. Camera traps haven’t offered definitive evidence, and experts can’t identify its tracks with certainty. But within the past decades, researchers have developed methods that can detect even the most elusive species. So how does it work? Hélène Morlon & Anna Papadopoulou dig into DNA metabarcoding.

Lesson by Hélène Morlon and Anna Papadopoulou, directed by Blok Magnaye.
