Lesson plan for eDNA outreach

Would you like to teach school students about eDNA metabarcoding in a way that goes beyond the usual explanation of just "what is eDNA"? Check out my lesson plan and activity below for a 2-hour session that works great with high school learners. I was interested in teaching 16-year-old students about eDNA sampling, eDNA extractions, …

Exciting new tool for marine conservation: environmental DNA

Fish and other aquatic animals shed DNA into the surrounding water. This means that seawater is filled with the DNA of the animals living there, and this is known as environmental DNA (eDNA). Scientists have used environmental DNA to study a range of animals, from earlier eDNA studies in 2008 (e.g. on the invasive American Bullfrog), …
