Environmental DNA: Searching for a Signal

The Wet Lab is hosting a lecture on environmental DNA at the La Jolla Riford Library on Tuesday, June 6th, from 6:30pm – 7:30pm.  Kirsten Harper, PhD from the University of Stirling, Scotland will discuss how scientists can use DNA from the environment to detect (and work to stop!) invasive species from taking over a habitat.



Environmental DNA (eDNA) is DNA collected from the environment (in soil, water, air, etc.) and can be used as a powerful tool for detecting the presence of certain animals. It has been used in oceans, lakes and rivers to detect rare and invasive species. Most studies have focused on fish and amphibians, but what about crustaceans? The American signal crayfish is highly invasive in Scotland. Faster detection can mean better control, or even prevention. eDNA may be the key to saving Scotland’s lochs and rivers from this unwanted invader.

This event is part of the San Diego Wetlab’s citizen science lecture series held every first Tuesday at 6:30pm at the La Jolla Library and every third Thursday at 6:30pm at the Downtown Library. Please check the San Diego library system events page for location details and changes in the upcoming schedule.
