Abstract Fungi are widely distributed in all terrestrial ecosystems, and they are essential to the recycling of nutrients in all terrestrial habitats on earth. We wanted to determine the relationship between soil fungal communities and geochemical factors (geographical location and soil physicochemical properties) in three widely separated geographical regions (the Antarctic, Arctic, and Tibet Plateau). Using high-throughput Illumina amplicon sequencing, we characterized the fungal communities in 53 soil samples collected from the three regions. The fungal richness and diversity indices were not significantly different among the three regions. However, fungal community composition and many fungal taxa (Thelebolales, Verrucariales, Sordariales, Chaetothyriales, Hypocreales, Pleosporales, Capnodiales, and Dothideales) significantly differed among three regions. Furthermore, geographical location (latitude and altitude) and six soil physicochemical properties (­ SiO42−-Si, pH, ­NO3−-N, organic nitrogen, ­NO2−-N, and organic carbon) were significant geochemical factors those were correlated with the soil fungal community composition. These results suggest that many geochemical factors influence the distribution of the fungal species within the Antarctic, Arctic, and Tibet Plateau.

Introduction Fungi represent a large proportion of the biodiversity on Earth that comprise approximately 100,000 described species (Kirk et al. 2008), but up to 5.1 million species of global fungal diversity are estimated to exist in nature (Blackwell Communicated by A.

2011). They are widely distributed in all terrestrial ecosystems from the tropics to bipolar regions and typically live in highly diverse communities composed of multiple ecological guilds, such as saprotroph (live on dead material: dung, leaf, plant, soil, wood), symbiotroph (ectomycorrhizal, ericoid mycorrhizal, endophyte, lichenized), and pathogens of plants and animals (Nguyen et al. 2016). Despite their enormous diversity and importance in ecosystem functions, diversity and distribution of soil
