This is really beautiful, interesting and important at the same time. SPUN: *A hidden infrastructure* ➡️ Underground networks "Beneath our feet lie networks of invisible ecosystem engineers: arbuscular mycorrhizal (AM) fungi. These fungi form trading relationships with more than 70% of plant species, building networks of tubular cells called hyphae that extend the surface area of root systems up to a hundred-fold. Collectively, these networks comprise one of Earth's circulatory systems." ➡️ 📖 https://a-hidden-infrastructure.spun.earth/story/a-hidden-infrastructure 🌐 https://a-hidden-infrastructure.spun.earth/story/mycorrhizal-infrastructure-map #biology #mycorrhizal #mycorrhizalFungi #fungi #SPUN #VrijeUniversiteitAmsterdam #VUamsterdam #science #cartography
