shows unequivocally that considerable amounts of carbon—the energy currency of all ecosystems—can flow through the hyphae of shared fungal symbionts from tree to tree, indeed, from species to species, in a temperate forest. Because forests cover much of the land surface in the Northern Hemisphere, where they provide the main sink for atmospheric CO2, an understanding of these aspects of their carbon economy is essential.” Nature called my discovery the wood-wide web, and the floodgates opened.
