How we can detect pretty much anything - Hélène Morlon and Anna Papadopoulou

Let’s Begin…

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.

Lichens are very sensitive to sulfur dioxide, a gas that is emitted from fossil fuel combustion at power plants. Imagine that you are a scientist who studies an endangered beetle species and suspects that it feeds primarily on lichens. The construction of a power plant next to a forest inhabited by this species will negatively affect lichens and the beetles that feed on them. How could you use DNA-metabarcoding to provide evidence that the endangered beetle species feeds indeed on lichens?
