This information is key for better quantification of mycorrhizal impacts on ecosystem processes and for incorporating mycorrhizal pathways into global biogeochemical models. Here we present the first high-resolution maps of fine root stocks colonized by arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) fungi (MgC ha−1). The maps were assembled by combining multiple open-source databases holding information on root biomass carbon, the proportion of AM and EcM tree biomass, plot-level relative abundance of plant species and intensity of AM and EcM root colonization. We calculated root-associated AM and EcM abundance in 881 spatial units, defined as the combination of ecoregions and land cover types across six continents. These maps serve as a basis for future research where continuous spatial estimates of root mycorrhizal stocks are needed. | Research Discipline: | Natural sciences > Biological sciences > Microbiology > Mycology (01060804) | Keywords: | mycorrhiza;fine root biomass;mycorrhizal colonization;arbuscular mycorrhiza;ectomychorriza;global assessment;FOS: Biological sciences;FOS: Biological sciences | DOI: | 10.5061/dryad.866t1g1tt | Link to publication/dataset: | https://datadryad.org/stash/dataset/doi:10.5061/dryad.866t1g1tt | Source: | Dryad. 10.5061/dryad.866t1g1tt https://datadryad.org/stash/dataset/doi:10.5061/dryad.866t1g1tt | Publications related to the dataset: | 10.1038/s41597-022-01913-2 | License: | Creative Commons Zero v1.0 Universal (CC0-1.0) | Access Rights: | Open Access | Category: | DS | Type: | Dataset |
