“…Seasonal changes can affect the diversity of microorganisms [45][46][47][48], and in general, the richness of bacteria in the same habitat is higher than that of fungi. The diversity of bacteria in this study was significantly higher than that of fungi (Figure 2), congruent with previous studies [20,49]. There were significant differences in fungal diversity among seasons, but there was no significant difference in bacterial diversity among seasons (Table S2).…”

“…Therefore, fungi are more susceptible to precipitation and temperature changes caused by seasonal changes than bacterial communities; hence fungi and bacteria have different adaptability to environmental changes [20,38]. The change trend of fungal Shannon diversity in the current study was similar to that of He et al [20], and the change trend of bacterial diversity was also similar to previous studies [49,51]. The increase in soil moisture caused by summer precipitation may be one reason for the increase in microbial richness [37,40].…”

Hazelnut is one of the four major nuts in the world and has high nutritional and economic value. This study employed Illumina sequencing of ITS rDNA and 16S rRNA genes to identify the seasonal changes in soil microbial community, the predominant environmental factors driving microbial community composition, and the differences in soil microbial composition among different species of the genus Corylus. We found that the soil microbial community composition of species of Corylus changed significantly with the change in seasons. Corylus heterophylla and Corylus kweichowensis had more ectomycorrhiza in their soil compared to Corylus avellane. The main factor influencing fungal community composition in soil was the available potassium, while that of bacteria was the total phosphorus content. Co-occurrence network analysis revealed that the ratio of positive interaction to negative interaction in soil of C. heterophylla and Ping’ou (C. heterophylla × C. avellane) was higher, while the negative interaction of soil community structure in C. avellane was greater. The bacterial community was more stable than the fungal community according to microbial diversity and co-occurrence network analyses. The findings of this research may facilitate improvements to the production and soil system management in hazel planting processes.

“…Forest is a crucial component of the global terrestrial ecosystem (Drake & Franks, 2003). Afforestation however, can alter the physical and chemical properties of soil (Han et al., 2021; Zhu et al., 2021). Soil in different regions has different physical and chemical properties, and soil chemical properties greatly influence soil microbial community composition and diversity (Deng et al., 2017; Gunina et al., 2017; J. Liu et al., 2018).…”

“…As it is generally accepted that the structure of soil microbial community in forest ecosystem is mainly influenced by tree species, several studies have elucidated the effects of single tree species and soil nutrients on soil microbial community (Ding et al., 2017; Nacke et al., 2016; Scheibe et al., 2015). Afforestation changes the abundance of oligotrophic phylum in soil, such as Actinobacteria and Bacteroidetes, and its effect is greater on the abundance of the bacterial community than on its diversity (Han et al., 2021). The change in the pattern of soil bacterial community composition, facilitated by tree species, is determined by studying the response of a few core bacterial phyla that have high abundance, especially Acidobacteria and Proteobacteria (Lu et al., 2019).…”

“…(2017) indicated that vegetation type affects several environmental variables, such as pH, moisture content (MC), and available N, and modifies them directly or indirectly affecting soil microbial diversity in a meadow grassland. Numerous studies have indicated that the transformation from natural forest to other vegetation types can affect the structure of edaphic microbial community and physical and chemical properties of the soil (Han et al., 2021; Qiu et al., 2020; Upchurch et al., 2008; Wu et al., 2020; Yu et al., 2013; Zhu et al., 2021). However, few studies have explored the soil microbial characteristics associated with different vegetation types in the middle subtropical region.…”

Single and mixed vegetation types have significant effects on soil parameters and the composition and diversity of soil bacterial community. To understand the influence of different vegetation types on the structure of soil bacterial community across soil depth in a subtropical forest, we assessed the relative abundance of edaphic bacterial community and soil parameters, including pH, cation exchange capacity (CEC), and dissolved organic C in Daiyun Mountain Nature Reserve in Fujian Province, southeastern China. The study area constitutes pine coniferous forest (CF) of Pinus taiwanensis Hayata, broad‐leaved forest (BF) of Castanopsis fabri Hance, and a mixed forest comprising CF and BF (MF). Quantitative polymerase chain reaction (PCR) and Illumina sequencing of 16S ribosomal DNA were used to analyze the abundance, diversity, and composition of soil bacteria. The results showed that the pH, CEC, and diversity of tree species are all associated with the composition of bacterial community in the soil. It was found that CEC, soluble organic N, and pH largely affected the structure of soil bacterial community in A horizon, whereas CEC, moisture content, and organic P affected the structure of soil bacterial community in B horizon. We found that the dominant taxa in the CF and BF were Proteobacteria and Acidobacteria, respectively. The results of both mental and random forest analyses displayed groups according to vegetation types, indicating that the bacterial communities in the research site were significantly influenced by vegetation types in subtropical forests. The study highlights the ecological effects of forest management and elucidates the differences in the functional structure of soil bacterial communities under different vegetation types and soil depths.

Soil bacterial taxa have important functional roles in ecosystems (e.g. nutrient cycling, soil formation, plant health). Many factors influence their assembly and regulation, with land cover types (e.g. open woodlands, grasslands), land use types (e.g. nature reserves, urban green space) and plant–soil feedbacks being well‐studied factors. However, changes in soil bacterial communities in situ over light–dark cycles have received little attention, despite many plants and some bacteria having endogenous circadian rhythms that could influence soil bacterial communities. We sampled surface soils in situ across 24‐h light–dark cycles (at 00:00, 06:00, 12:00, 18:00) at two land cover types (remnant vegetation vs. cleared, grassy areas) and applied 16S rRNA amplicon sequencing to investigate changes in bacterial communities. We show that land cover type strongly affected soil bacterial diversity, with soils under native vegetation expressing 15.4%–16.4% lower alpha diversity but 4.9%–10.6% greater heterogeneity than soils under cleared vegetation. In addition, we report time‐dependent and site‐specific changes in bacterial network complexity and between 598–922 ASVs showing significant changes in relative abundance across times. Native site node degree (bacterial interactions) at the phylum level was 16.0% higher in the early morning than in the afternoon/evening. Our results demonstrate for the first time that light–dark cycles have subtle yet important effects on soil bacterial communities in situ and that land cover influences these dynamics. We provide a new view of soil microbial ecology and suggest that future studies should consider the time of day when sampling soil bacteria.
