“…Moreover, as a key decomposer, Basidiomycota produces enzymes (peroxide) that degrade plant components such as cellulose and lignin, hence increasing the soil's overall carbon pool [34]. The fungal genus of Saitozyma was most abundant in all densities; similar results were also seen in pine forest areas by [35]. The species belonging to this genus are typically soil-borne yeasts and often also found in environmental sequencing studies [36].…”

Soil microorganisms provide valuable ecosystem services, such as nutrient cycling, soil remediation, and biotic and abiotic stress resistance. There is increasing interest in exploring total belowground biodiversity across ecological scales to understand better how different ecological aspects, such as stand density, soil properties, soil depth, and plant growth parameters, influence belowground communities. In various environments, microbial components of belowground communities, such as soil fungi, respond differently to soil features; however, little is known about their response to standing density and vertical soil profiles in a Chinese fir monoculture plantation. This research examined the assemblage of soil fungal communities in different density stands (high, intermediate, and low) and soil depth profiles (0–20 cm and 20–40 cm). This research also looked into the relationship between soil fungi and tree canopy characteristics (mean tilt angle of the leaf (MTA), leaf area index (LAI), and canopy openness index (DIFN)), and general growth parameters, such as diameter, height, and biomass. The results showed that low-density stand soil had higher fungal alpha diversity than intermediate- and high-density stand soils. Ascomycota, Basidiomycota, Mucromycota, and Mortierellomycota were the most common phyla of the soil fungal communities, in that order. Saitozyma, Penicillium, Umbelopsis, and Talaromyces were the most abundant fungal genera. Stand density composition was the dominant factor in changing fungal community structure compared to soil properties and soil depth profiles. The most significant soil elements in soil fungal community alterations were macronutrients. In addition, the canopy openness index and fungal community structure have a positive association in the low-density stand. Soil biota is a nutrient cycling driver that can promote better plant growth in forest ecosystems by supporting nutrient cycling. Hence, this research will be critical in understanding soil fungal dynamics, improving stand growth and productivity, and improving soil quality in intensively managed Chinese fir plantations.

“…Soil microorganisms are essential components involved in a variety of important processes in forest ecosystems [3]. They have various relationships with plants, such as litter decomposition and nitrogen fixation, which makes nitrogen available to plants, and until now it has been assumed that their composition varies depending on the vegetation [2]. In this context, soil microbial communities are considered to reflect the state of the forest ecosystem, and the influence of climate change on soil microbial communities has been studied in various ways.…”

Unexpected vegetation shift is a serious problem caused by climate change, resulting in considerable damage to local communities. It is necessary to be continuously monitored, and the soil microbial community is expected to reflect the pressure on forest ecosystems due to climate change. We investigated soil bacterial and fungal communities in Odaesan at a four-year interval through eDNA meta-barcoding and analyzed the compositional and functional differences between forest types (Mongolian oak (Quercus mongolica) forest with and without Manchurian firs (Abies holophylla)) and sampling years. As a result, denitrifiers predominated in the presence of Manchurian firs, but there was no difference in the influence of climate change by forest type. Although tree vegetation remained stable, the microbial communities significantly changed over four years. This result demonstrates that climate change significantly shifts the microbial communities, even if not enough to trigger a vegetation shift, thus a microbial indicator can be developed to assess the press disturbance accumulated on the forest ecosystem. Through this study, we identified the influence of Manchurian firs and that of climate change on soil microbial communities in temperate forests and demonstrated the potential of the microbial community as a proactive indicator of vegetation shift due to climate change.

Aims This study explored the trends in soil fungal patterns and their responses to carbon and nitrogen during the succession in Alpine grassland in the Qilian Mountain area. Methods Illumina sequencing of ITS genes was used to characterize the soil fungal construct, and the FUNGuild database to predict functional groups in Alpine grassland succession from swamp meadow to alpine meadow, steppe meadow. Soil carbon and nitrogen, vegetation carbon and nitrogen, and soil enzyme activity were also investigated. ResultsThe soil fungal OTUs increased with succession in the rst stages but then reached a relatively stable state in the second successional stages. The sobs and Chao1 index showed the same trend as OTUS during succession. And there are signi cant differences in fungal community structure among different succession stages. During succession, most phyla showed linear decreases trends; whereas Ascomycota showed linear increases. The relative abundance of Pathotroph and Saprotroph of fungal functional increased with the successional stages, while the Symbiotroph had no change during succession. We also found that NH4 + -N is the dominating factor, which affects the structure of fungal community across all successional stages, and soil microbial carbon has the greatest in uence on the variation of functional communities.Conclusions Our ndings indicate that the community dramatically shifted with succession in the rst stages but then reached a relatively stable state in the second successional stages, while the soil fungal function group did not follow this rule. NH4 + -N and soil microbial carbon had the greatest in uence on the community and function of fungi, respectively.
