Do trees talk to each other? In this episode we are exploring the underground world of Fungal Networks with Vincent Merckx, assistant professor at the Institute for Biodiversity and Ecosystem Dynamics and research fellow at Naturalis. His research focuses on a specific type of fungi that exchanges nutrients with plants, and its mechanisms have a remarkable resemblance to the economic model of a fair trade market. We also ask Vincent what he thinks of the idea that plants can really "communicate" with each other by using the underground network of fungi that they are connected to.
