“…Assembly mechanisms are closely linked to changes in community structure, diversity, and the ecological functions they support ( Fukami, 2015 ). This phenomenon has been extensively studied in various ecosystems, such as soil microbes ( Wang et al., 2022 ; Cao et al., 2023 ), bacterioplankton ( Dai et al., 2017 ), intertidal communities ( Loke and Chisholm, 2023 ), and plants ( Peter and Harrington, 2018 ; Tanunchai et al., 2023 ). Assembly processes are influenced by various environmental factors, with community turnover cycles limiting exploration.…”

Microorganisms are important members of seagrass bed ecosystems and play a crucial role in maintaining the health of seagrasses and the ecological functions of the ecosystem. In this study, we systematically quantified the assembly processes of microbial communities in fragmented seagrass beds and examined their correlation with environmental factors. Concurrently, we explored the relative contributions of species replacement and richness differences to the taxonomic and functional β-diversity of microbial communities, investigated the potential interrelation between these components, and assessed the explanatory power of environmental factors. The results suggest that stochastic processes dominate community assembly. Taxonomic β-diversity differences are governed by species replacement, while for functional β-diversity, the contribution of richness differences slightly outweighs that of replacement processes. A weak but significant correlation (p < 0.05) exists between the two components of β-diversity in taxonomy and functionality, with almost no observed significant correlation with environmental factors. This implies significant differences in taxonomy, but functional convergence and redundancy within microbial communities. Environmental factors are insufficient to explain the β-diversity differences. In conclusion, the assembly of microbial communities in fragmented seagrass beds is governed by stochastic processes. The patterns of taxonomic and functional β-diversity provide new insights and evidence for a better understanding of these stochastic assembly rules. This has important implications for the conservation and management of fragmented seagrass beds.

“…In this study, the fungal communities within the mycorrhizal and soil ecological niches were directly or indirectly affected by abiotic factors. Both mycorrhizal and soil fungal communities can be directly or indirectly influenced by abiotic factors [58][59][60][61][62]. Soil serves as the immediate habitat for soil microbes and, as such, its physical and chemical properties directly impact the resident microorganisms.…”

It is generally believed that mycorrhiza is a microecosystem composed of mycorrhizal fungi, host plants and other microscopic organisms. The mycorrhiza of Rhododendron dauricum is more complex and the diverse morphology of our investigated results displays both typical ericoid mycorrhizal characteristics and ectomycorrhizal traits. The characteristics of ectendoomycorrhiza, where mycelial invade from the outside into the root cells, have also been observed. In order to further clarify the mycorrhizal fungi members and other fungal communities of R. dauricum mycorrhiza, and explore the effects of vegetation and soil biological factors on their community structure, we selected two woodlands in the northeast of China as samples—one is a mixed forest of R. dauricum and Quercus mongolica, and the other a mixed forest of R. dauricum, Q. mongolica, and Pinus densiflor. The sampling time was during the local growing season, from June to September. High-throughput sequencing yielded a total of 3020 fungal amplicon sequence variants (ASVs), which were based on sequencing of the internal transcribed spacer ribosomal RNA (ITS rRNA) via the Illumina NovaSeq platform. In the different habitats of R. dauricum, there are differences in the diversity of fungi obtained from mycorrhizal niches, and specifically the mycorrhizal fungal community structure in the complex vegetation of mixed forests, where R. dauricum is found, exhibits greater stability, with relatively minor changes over time. Soil fungi are identified as the primary source of fungi within the mycorrhizal niche, and the abundance of mycorrhizal fungi from mycorrhizal niches in R. dauricum is significantly influenced by soil pH, organic matter, and available nitrogen. The relationship between soil fungi and mycorrhizal fungi from mycorrhizal niches is simultaneously found to be intricate, while the genus Hydnellum emerges as a central genus among mycorrhizal fungi from mycorrhizal niches. However, there is currently a substantial gap in the foundational research of this genus, including the fact that mycorrhizal fungi from mycorrhizal niches have, compared to fungi present in the soil, proven to be more sensitive to changes in soil moisture.

Understanding soil fungal diversity under global warming is significant for the assessment of climate change impacts on soil health and soil nutrient transformation. The interaction effect of warmer temperatures and fertilization regimes on fungal communities in the soils of winter wheat fields is unclear. Two-year potting experiments were conducted under nighttime warming and different fertilization regimes. The two-year continuous temperature increase significantly decreased the soil’s pH. Warming and fertilization did not significantly change the dominant fungal phyla in the soil. However, it significantly increased the soil fungal richness and diversity compared with no warming and no fertilization. Warming increased richness and diversity by 4.15% and 4.24%, respectively, and fertilization increased richness and diversity by 14.15% and 4.27%, respectively. Furthermore, warming significantly increased the relative abundance of Fusarium, which is the causal agent of winter wheat weat root rot, from 1.75–3.62%. However, fertilization reduced the relative abundance of Fusarium, especially under the combined application of organic and inorganic fertilizers, suggesting that organic manure addition could impair soil fungal pathogens under future warming. The structural equation model demonstrated that the influence of soil temperature on fungal diversity was direct and mediated through soil carbon nitrogen ratios. Soil temperature and soil organic matter directly affected soil fungal diversity and were the most significant parameters influencing fungal diversity.
