Biological invasions constitute a global environmental threat that rapidly alters natural communities and ecosystem functioning. A way to understand the success of alien trees in novel ecosystems is by comparing their ecological strategies with those of natives. Plants often associate with mycorrhizal fungi in their roots to enhance nutrient acquisition. According to fungal identity, morphological structures and functioning, different types of mycorrhizas can be distinguished. Despite the phylogenetic imprints that often characterize mycorrhizal distribution among plants, it is well known that mycorrhizal types vary across environmental gradients, vegetation types and plant life forms. Then, at the global scale, the different types of mycorrhizas are not randomly distributed across biomes but rather related to environmental variables. In this chapter we examine the patterns of mycorrhizal distribution in native and alien …
