As the leaves start to pop out, it’s natural to look up and admire the trees. But actually, there’s a lot of action happening underneath your feet. Beneath you is a complex network of fungal trade routes carrying essential nutrients to the roots of plants, mined from the soil by fungus. It’s a subterranean supply chain.

But how exactly do these complex networks form? How does the fungus decide where to ship which resources, or where to build roads? Basically, how does a brainless thread make decisions?

Host Flora Lichtman is joined by Dr. Toby Kiers, an author on a recent study of those networks, and professor of evolutionary biology at Vrije University in Amsterdam. She’s also the executive director of the Society for the Protection of Underground Networks (SPUN).
