TED-Ed: How we can detect pretty much anything | Hélène Morlon and Anna Papadopoulou

The video explores the use of environmental DNA (eDNA) and DNA metabarcoding to detect elusive species, monitor biodiversity, and understand ecosystem interactions. It highlights the process of DNA metabarcoding, which involves extracting DNA from environmental samples and using PCR to identify species. Applications include discovering new species, tracking invasive species, and studying pollination networks. eDNA also provides insights into historical biodiversity and helps understand climate change impacts. This technology offers a powerful tool for real-time biodiversity monitoring and conservation efforts.
