Vegetation impacts on ecosystem functioning are mediated by mycorrhizas, plant–fungal associations formed by most plant species. Ecosystems dominated by distinct mycorrhizal types differ strongly in their biogeochemistry. (...) Here we present global, high-resolution maps of vegetation biomass distribution by dominant mycorrhizal associations.(...) Soil carbon stocks in both topsoil and subsoil are positively related to the community-level biomass fraction of ectomycorrhizal plants, though the strength of this relationship varies across biomes. We show that human-induced transformations of Earth’s ecosystems have reduced ectomycorrhizal vegetation, with potential ramifications to terrestrial carbon stocks.
DocBiodiv's insight:
"A study in @NatureComms shows that human impacts have greatly reduced plant-fungus symbioses, which play a key role in sequestering carbon in soils. Restoring these ecosystems could be one strategy to slow climate change."
