“…Bulk soil microbial community diversity is affected by season, and the relative abundance of microbial communities differs between seasons [40]. According to the alpha diversity analysis, we found that the diversity of bulk soil microbial communities in SBL changed significantly with season, with the highest diversity in spring, followed by summer, and the lowest diversity in autumn.…”

Urban forests play a crucial role in the overall health and stability of urban ecosystems. Soil microorganisms are vital to the functioning of urban forest ecosystems as they facilitate material cycling and contribute to environmental stability. This study utilized high-throughput sequencing technology to examine the structural characteristics of bacterial and fungal communities in the bulk soil of six different forest stands: Phyllostachys pubescens (ZL), Metasequoia glyptostroboides (SSL), Cornus officinalis (SZY), mixed broad-leaved shrub forest (ZKG), mixed pine and cypress forest (SBL), and mixed broad-leaved tree forest (ZKQ). Soil samples were collected from each forest stand, including the corners, center, and edges of each plot, and a combined sample was created from the first five samples. The results revealed that among the bacterial communities, ZKG exhibited the highest alpha diversity in spring, while ZL demonstrated the highest alpha diversity in both summer and autumn. Proteobacteria was the most abundant bacterial phylum in all six forest stand soils. The dominant fungal phylum across the six forest stands was identified as Ascomycota. Notably, the microbial community diversity of SBL bulk soil exhibited significant seasonal changes. Although ZL exhibited lower bacterial community diversity in spring, its fungal community diversity was the highest. The bulk soil microbial diversity of ZL and SSL surpassed that of the other forest stands, suggesting their importance in maintaining the stability of the urban forest ecosystem in the Zhuyu Bay Scenic Area. Furthermore, the diversity of the bulk soil microbial communities was higher in all six stands during spring compared to summer and autumn. Overall, this study provides valuable insights into the seasonal variations of bulk soil microbial communities in urban forests and identifies dominant tree species, offering guidance for tree species’ selection and preservation in urban forest management.

“…, which grow slower, may decline(Fierer et al 2012). Microorganisms were particularly vulnerable to environmental changes(Li et al 2024b). The Monte Carlo permutation test demonstrated that CAT was strongly associated with a modi cation of the bacterial community composition, as also reported by Tang(Tang et al 2024).…”

Background and aims Fertilization is a critical management practice for improving soil fertility and increasing agricultural production. We still don't fully understand how biotic and abiotic variables interact with soil multifunctionality in the rhizosphere soil of legume-Gramineae mixtures following fertilization. Studies on the effects of fertilization on the bacterial composition of legume-Gramineae mixtures in particular geographical areas are scarce. Methods To tackle this matter, we set up five treatments: no fertilizer zone (CK, N0P0K0), nitrogen-phosphorus-potassium zone (NPK, N2P2K2), nitrogen-less zone (PK, N0P2K2), phosphorus-less zone (NK, N2P0K2), and potassium-less zone (NP, N2P2K0). The soil data were measured to assess the response mechanism of legume-Gramineae mixtures to fertilization management. Results The fertilization treatment resulted in a beneficial impact on the rhizosphere soil nutrients, enzyme activity, and biological characteristics, reaching the maximum under N2P2K2 treatment. The analysis of the bacterial community revealed that the oligotrophic taxa decreased primarily due to fertilizer addition, including Acidobacteria, and enhancing the copiotrophic taxa, such as Bacteroidetes and Proteobacteria, in the soil. Furthermore, according to FAPROTAX analysis, the results indicated variations in the function of the bacterial community in the rhizosphere soil of legumes and gramineae. Fertilization indirectly affected soil versatility by changing the diversity and composition of bacterial communities. Conclusions The bacterial community can be reshaped and the properties of the rhizosphere soil can be modified by different fertilization treatments, thus impacting the potential function of the bacterial community. This study has the potential to offer scientific guidance for the rational management of fertilization in legume-Gramineae mixtures.
