我們如何檢測到幾乎任何東西 – 海倫·莫倫和安娜·帕帕多普盧

探索科學家如何使用環境 DNA (脫氧核糖核酸) 在一種稱為 DNA 元條形碼的技術中發現和追踪物種.

—

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.
