- Mycorrhizal fungi form underground networks that connect plant roots, circulate nutrients, and support ecosystems above ground, with their complex interactions being actively studied.
- A 2025 model using machine learning on 25,000 soil samples predicted mycorrhizal 'hot spots,' including in the Alaskan tundra, leading to expeditions to sample and identify rare, endemic species.
- Fungal networks store over one-third of global carbon emissions annually, with permafrost in the Alaskan tundra holding about 1 trillion metric tons of carbon, highlighting their critical role in climate regulation.
- Climate change threatens these fungal communities through warming temperatures, thawing permafrost, and wildfires, with less than 10% of predicted hot spots in protected areas, urging conservation efforts.
- Research by SPUN involves robotic imaging and genetic analysis to understand nutrient flows and biodiversity, revealing that fungi act as active 'farmers' and influencers in ecosystems, not just passive partners.
