Environmental DNA: Searching for a signal

The Wet Lab is hosting an ecology lecture at the San Diego Central Library on Thursday, April 20 from 6:30pm – 7:30pm.  Kristen Harper, PhD from the University of Stirling will discuss how environmental DNA can be used to detect invasive species and ecological patterns.


Environmental DNA (eDNA) is a powerful tool for detecting species using DNA deposited in the environment. 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.
