Mycorrhizal fungi associate with the majority of plant species with large consequences on ecosystem nutrient, carbon and water cycling. Two main types of mycorrhizal fungi, arbuscular mycorrhizal (AM) fungi and ectomycorrhizal (EM) fungi, dominate terrestrial ecosystems. Most global distribution modelling of AM and EM associations describe the distribution of AM and EM plants, and not fungi directly. However, significant functional trait variation occurs within AM and EM fungal guilds. Therefore, modelling range sizes and determinants of these ranges of fungi directly is likely to create spatial maps that are a better proxy of ecosystem function than guild‐level lumping of AM and EM plant distributions.

全局菌根真菌范围的大小在菌根行会内和之间有所不同，但与传播特征无关

菌根真菌与大多数植物物种相关，对生态系统养分，碳和水的循环产生重大影响。两种主要类型的菌根真菌是丛枝菌根（AM）真菌和外生菌根（EM）真菌，它们主导着陆地生态系统。大多数AM和EM关联的全局分布模型都描述了AM和EM植物的分布，而不是直接描述真菌。但是，AM和EM真菌行会内部会发生明显的功能性状变异。因此，直接对真菌的范围大小和这些范围的决定因素进行建模很可能会创建比AM和EM植物分布的行会集总更好的生态系统功能的空间图。
