How Do You Protect a Species You Can’t See?

“Conservation relies on knowing what species are located where. That means identifying where vulnerable plants and animals are to protect them, and knowing where harmful, invasive plants and animals are to get rid of them. It’s hard to know where things are underwater, so conservation is always more complicated there. Untitled

To help study these species that are hard to see or otherwise observe, some scientists have turned to something called environmental DNA (or eDNA) — genetic material that’s been shed into the environment, often from fur, skin flakes, body fluids and feces.

Studying eDNA lets scientists peer into the depths of oceans, lakes and rivers. It also works on land, but that takes more effort. The scientists developing lab techniques for eDNA say it’s time to let it do the important work of finding out where things are — not just manatees in Africa, but a broad range of species with roles in a range of conservation issues.”
