“…Furthermore, in the nMDS and heat map analyses (Figures 2 and 3), the samples were grouped by three of the four tree species (S. macrophylla was excluded). These findings agree with previous studies that concluded that the bacterial community structure in soil is related to urban tree species [16]. Interestingly, applying biochar-based compost increased the relative abundance of potential nitrogen-fixing bacterial groups (Figure 5), and the tree species affected the species of the nitrogen-fixing bacteria in the soil as well.…”

“…Numerous studies have shown that soil microbes are sensitive to plant species composition, biomass, diversity, and soil structure [12][13][14]. Recent studies also found that tree species diversity in an urban forest affect the soil bacterial and fungal communities, indicating that the design of urban greenspaces influences microbial communities of urban soil [15,16].…”

Urban forests are key to mitigating the Urban Heat Island Effect, which contributes to temperature increases in urban areas. However, the trees in these forests are usually under stress because urban soil is typically degraded. Biochar/compost amendments help with soil management by improving the physiochemical properties and bacterial communities of soil. Here, we compared the physiochemical properties and bacterial communities before and after (1) biochar-only and (2) biochar-based compost amendments. Our results suggested that biochar-only application did not improve soil properties after 1 year of treatment, whereas in the biochar-based compost treatment, the soil properties and bacterial communities changed after just four months. The increase in potassium and decrease in organic material, calcium, and available phosphorus in the soil of the former treatment indicated that the nutrient uptake of its trees had improved. Although there was no significant variation in the soil’s total nitrogen, the higher abundance of potential nitrogen-fixing bacteria in the biochar-based treatment suggested that the soil contained a supplement to nitrogen. Our results show that biochar-based compost amendment improves soil quality and associated bacterial communities in urban forest management.

“…The results of this study showed that vegetation type has an impact on urban forest bulk soil microbial communities [32]. There have also been studies using MiSeq sequence analysis to assess the structure of microbial communities, revealing specific genetic structures of bacterial and fungal communities in similar soils under different tree species, and observing that tree species have a significant effect on soil microbial diversity [41]. Among the six forest stands, the bacterial Shannon index of ZL was highest in both summer and autumn, and the Shannon index in spring was relatively high, indicating that ZL had higher bacterial diversity.…”

“…In the fungal community, ZL and SBL in spring, ZKQ and SSL in summer, and SZY and SSL in autumn showed a higher bacterial diversity. The diversity was high, among which ZL and SSL appeared with the highest frequency, indicating that the bulk soil microbial community structures in the ZL and SSL were relatively complex [41]. It can be used as a dominant tree species for maintaining the stability of urban forest ecosystems.…”

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.

“…With the rapid development of urbanization, urban environmental conditions, such as impervious surfaces and the urban heat island effect, can locally exacerbate destructive extreme climate events [18][19][20][21][22]. Woody species growing in urban areas are the main way to maintain urban ecological services [23,24], which form green spaces in cities, increase the elasticity of the urban ecosystem, mitigate flooding and improve the quality of the urban environment [25][26][27][28]. In the context of climate change, urban woody plants are facing increasingly severe pressure and harm [11,29,30].…”

The frequency and intensity of droughts combined with heatwave events have increased under climate change, increasing destruction in urban areas and leading to severe impacts on urban plants. These impacts remain poorly understood at the species level. Here, we investigate the effects of a drought–heatwave event on 12 urban woody species using in situ records of the dynamic changes in physiological traits in the field before, during and after the drought–heatwave event to assess resistance and resilience to hot drought. We found the following: (1) Hydraulic and photosynthesis traits showed an instantaneous decline during the hot drought event in the 12 species, with severe drought-induced xylem embolism in hydraulic systems and a high percentage loss of hydraulic conductivity (PLC). (2) The two conifer species were less resistant to hot droughts than broadleaves but capable of post-stress recovery, suggesting that conifers showed better resilience and that broadleaves showed better resistance under hot drought stress. (3) The evergreen species showed strong resistance, while three deciduous species showed strong resilience to hot drought stress. (4) The three shrubs may be more vulnerable to hot droughts than trees, as they showed lower resistance and were not able to recover the current year’s growth.
