“…Certainly, other potential factors also act on the richness of ectomycorrhizal fungi, such as the soil C/N [16] or pH of the timberlines [17]. Suillus, Tomentella and Cortinarius of Basidiomycota and Cenococcum of Ascomycota are dominant genera of ectomycorrhizal fungi at several timberlines all over the world [16,[18][19][20].…”

“…Soil saprotrophic fungi are usually more abundant under forests than shrubs at timberlines; for instance, Mucoromycota [22]. Saprotrophic fungi from Basidiomycota, Ascomycota and Zygomycota also occur frequently in soils from timberline forests, which are rich in wooden substrates [20]. These saprophytic fungi are believed to promote the turnover of soil organic matter in these harsh ecosystems together with ectomycorrhizal fungi [22].…”

“…We know that the changes in the soil fungal community occur along the elevation gradient due to the tree height [8], but tree species and obvious transitional differences in the number and spatial distribution of trees at different timberline zones with different vegetation characteristics also result in soil environmental heterogeneity [8,23]. For instance, in the Shenlongjia timberline ecotone, the shrubbery has a considerable amount of total and available phosphorus in the soil compared to the coniferous forest, but the soil pH and humidity levels are reversed [20]. Furthermore, in Changbai Mountains, the soil in the tree islands within the birch timberline ecotone has a significantly higher water content, total carbon and total nitrogen than open areas at equal elevation [23].…”

Soil fungal community characteristics of alpine timberlines are unclear. In this study, soil fungal communities in five vegetation zones across timberlines on the south and north slopes of Sejila Mountain in Tibet, China were investigated. The results show that the alpha diversity of soil fungi was not different between the north- and south-facing timberlines or among the five vegetation zones. Archaeorhizomyces (Ascomycota) was a dominant genus at the south-facing timberline, whereas the ectomycorrhizal genus Russula (Basidiomycota) decreased with decreasing Abies georgei coverage and density at the north-facing timberline. Saprotrophic soil fungi were dominant, but their relative abundance changed little among the vegetation zones at the south timberline, whereas ectomycorrhizal fungi decreased with tree hosts at the north timberline. Soil fungal community characteristics were related to coverage and density, soil pH and ammonium nitrogen at the north timberline, whereas they had no associations with the vegetation and soil factors at the south timberline. In conclusion, timberline and A. georgei presence exerted apparent influences on the soil fungal community structure and function in this study. The findings may enhance our understanding of the distribution of soil fungal communities at the timberlines of Sejila Mountain.

PAHs (Polycyclic Aromatic Hydrocarbons) increases the potential harm to ecosystem and human health.The fungi is considered as a powerful choice for degradation of PAHs. The researches on the effect of PAHs on fungal population in sediment/soil mostly stayed in the laboratory simulation that based on extreme pollution. This study investigated the fungal population of the urban wetland by high-throughput sequencing in situ micro-pollution state. Our statistical analysis revealed signi cant difference in the whole fungal population at the phylum among the three land use types. Among them, Ascomycota was the dominant fungi at the phyla in three land use types. Fungal genus of degrading PAHs were signi cantly correlated with Dibenz[a, h]anthracene (P = 0.018) in ditch wetland, Total Organic Carbon (P = 0.02) and Fluoranthene (P = 0.04) in riverine wetland, and Electrical Conductivity (P = 0.018) in agricultural land. PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States) suggested that 20 enzymes were present related to PAHs metabolism in three land use types.Speci cally, monoxygenase, dehydrogenase, and laccase were most abundant among inferred enzymes, indicating that the urban wetland had potential for the degradation of PAHs. This study contributed to indepth understanding of the structure and function of fungal population and provided a theoretical basis for PAHs microbial remediation in the in-situ environment.
