Webinar: Teen Earth Optimism – Using Environmental DNA to Study Biodiversity

Archived Webinar

The Zoom webinar with Invertebrate Zoologist Chris Meyer aired May 26, 2020, as part of the Teen Tuesday: Earth Optimism series. Watch a recording in the player above.


In this video, Invertebrate Zoologist Chris Meyer discusses how cutting edge environmental DNA (eDNA) techniques allow scientists to learn more than ever before about our planet’s biodiversity. eDNA analysis can reveal what species are present in a habitat using traces of DNA found in water or soil! Chris shares how he is using this technology in his research and why he is optimistic eDNA analysis and citizen science are helping us better understand and protect species.
