Environmental DNA basics: how we detect hidden life with Dr. Mark Davis

In this amazing episode, conservation biologist Dr. Mark Davis joins hosts Amy and Karla to explain environmental DNA (eDNA)—genetic material shed by organisms into their surroundings. This tool allows researchers to detect species in water, soil, and air without disturbing them. A fascinating look at how invisible clues in nature help protect biodiversity.

Highlights:

- Rediscovering the endangered salamander mussel in Illinois after 100 years using eDNA.

- Detecting rare Hawaiian birds through flower samples.

- eDNA enables faster, less invasive biodiversity surveys.

- Limitations include short DNA lifespan and data interpretation challenges.
