Wood Wide Web EXPOSED: Mycorrhizal Fungi Lock Carbon & Help Forests Survive Drought.

Can two underground fungal alliances make forests tougher — and lock away more carbon? In this episode, we bust the romantic “Wood Wide Web” myth (tree-to-tree charity) and show what the evidence supports instead: AM + ECM mycorrhizal TYPES that run different nutrient economies… and together can create a climate-resilient, carbon-storing forest. You’ll learn: • AM fungi (Arbuscular Mycorrhizae): phosphorus scavengers + glomalin “soil glue” → deeper, more stable mineral carbon (MAOM) • ECM fungi (Ectomycorrhizae): organic “nitrogen miners” + decomposition slowdown (the “Gadgil effect”) → thicker surface carbon (POM/duff) • Why MIXED stands can “overyield” (more growth), buffer drought, and store carbon across the full soil profile CHAPTERS: 0:00 The fungal forest secret 0:32 Mixed-mycorrhizae thesis 1:20 Two fungal guilds (AM vs ECM) 5:20 Myth bust & data (what the “Wood Wide Web” gets wrong) 11:20 Why myths stick (and why mechanisms matter) 15:04 Real-world evidence (overyielding + drought “insurance”) 20:24 Pack spotlight 23:28 Future fungal tools (warming shifts guilds) 25:28 Take action (what to do in restoration) Sources: • Mixed mycorrhizal strategies → higher forest productivity (Nature Communications, 2023): https://www.nature.com/articles/s4146... • Mycorrhizal type + drought resistance/resilience (Journal of Ecology, 2024): https://besjournals.onlinelibrary.wil... • “Mother trees / wood-wide web” skepticism (Nature Plants, 2024): https://www.nature.com/articles/s4147... • “Where the Wood-Wide Web narrative went wrong” (Undark, 2023): https://undark.org/2023/05/25/where-t... • Glomalin overview (USDA ARS PDF): https://www.ars.usda.gov/ARSUserFiles... • Global map: mycorrhizal distributions + carbon implications (2019): https://pubmed.ncbi.nlm.nih.gov/31700... • Global soil-carbon loss estimate from ECM decline (bioRxiv preprint, 2018): https://www.biorxiv.org/content/10.11... • 2025 overview on plant–mycorrhiza diversity for restoration (Trends in Ecology & Evolution, 2025): https://pubmed.ncbi.nlm.nih.gov/40813...
