New Study Reveals Underground Fungal Connections
Fungal networks stretch 110 quadrillion kilometers through Earth's topsoil.
Networks shuttle 4 billion metric tons of carbon annually, equivalent to 11% of human emissions.
Support 70% of plant species through symbiotic relationships.
Wild grasslands like Florida Everglades hold 40% of global fungal biomass.
Cultivated croplands have 50% lower fungal density due to fertilizers, fungicides, and tilling.
Evolutionary ecologist Justin Stewart and colleagues argue maps are 'urgently needed' for conservation.
Researchers created 'maps of ignorance' to guide future efforts, with five-year database updates.
