“…As a result, niche breadth and occurrence frequency showed highly consistent relationships with subcommunity assembly mechanisms. Microbial taxa with wider niche breadths usually show higher metabolic plasticity, thereby being less affected by environmental selection and more controlled by stochastic processes (Li et al., 2022; Luo et al., 2019; Pandit et al., 2009). In contrast, microbial taxa with narrower niches usually have stringent growth condition requirements and low occurrence frequencies, possibly accompanied by specific metabolic requirements, and thus are more influenced by environmental selection than by stochastic processes (Luo et al., 2019; Xu, Luo, et al., 2022; Xu, Vandenkoornhuyse, et al., 2022).…”

“…First, the differences in the ecological traits (e.g. cellular sizes and basal metabolism characteristics) of the functional groups could be the main reason for the variable subcommunity assembly mechanisms (Isabwe et al., 2022; Li et al., 2022; Luo et al., 2019; Pandit et al., 2009; Wang, Zhang, et al., 2017). For example, the subcommunity assembly mechanism of many prokaryotic and fungal functional groups (e.g.…”

Revealing the mechanisms underlying soil microbial community assembly is a fundamental objective in molecular ecology. However, despite increasing body of research on overall microbial community assembly mechanisms, our understanding of subcommunity assembly mechanisms for different prokaryotic and fungal taxa remains limited. Here, soils were collected from more than 100 sites across southwestern China. Based on amplicon high‐throughput sequencing and iCAMP analysis, we determined the subcommunity assembly mechanisms for various microbial taxa. The results showed that dispersal limitation and homogenous selection were the primary drivers of soil microbial community assembly in this region. However, the subcommunity assembly mechanisms of different soil microbial taxa were highly variable. For instance, the contribution of homogenous selection to Crenarchaeota subcommunity assembly was 70%, but it was only around 10% for the subcommunity assembly of Actinomycetes, Gemmatimonadetes and Planctomycetes. The assembly of subcommunities including microbial taxa with higher occurrence frequencies, average relative abundance and network degrees, as well as wider niches tended to be more influenced by homogenizing dispersal and drift, but less affected by heterogeneous selection and dispersal limitation. The subcommunity assembly mechanisms also varied substantially among different functional guilds. Notably, the subcommunity assembly of diazotrophs, nitrifiers, saprotrophs and some pathogens were predominantly controlled by homogenous selection, while that of denitrifiers and fungal pathogens were mainly affected by stochastic processes such as drift. These findings provide novel insights into understanding soil microbial diversity maintenance mechanisms, and the analysis pipeline holds significant value for future research.

“…Long‐term monitoring is important for assessing invasion success and understanding invasion trajectories over time (Caselle, Davis & Marks, 2018). In a long‐term study of the invasive species Alternanthera philoxeroides , researchers analysed plant community composition, species diversity, and nutrient cycling processes in invaded and uninvaded wetlands (Chen et al ., 2015; Li et al ., 2022 a ). Likens & Lindenmayer, (2018) noted that long‐term monitoring is also necessary for the evaluation of management interventions and the effectiveness of control strategies.…”

Weed communities influence the dynamics of ecosystems, particularly in disturbed environments where anthropogenic activities often result in higher pollution. Understanding the dynamics existing between native weed communities and invasive species in disturbed environments is crucial for effective management and normal ecosystem functioning. Recognising the potential resistance of native weed communities to invasion in disturbed environments can help identify suitable native plants for restoration operations. This review aims to investigate the adaptations exhibited by native and non‐native weeds that may affect invasions within disturbed environments. Factors such as ecological characteristics, altered soil conditions, and adaptations of native weed communities that potentially confer a competitive advantage relative to non‐native or invasive weeds in disturbed environments are analysed. Moreover, the roles of biotic interactions such as competition, mutualistic relationships, and allelopathy in shaping the invasion resistance of native weed communities are described. Emphasis is given to the consideration of the resistance of native weeds as a key factor in invasion dynamics that provides insights for conservation and restoration efforts in disturbed environments. Additionally, this review underscores the need for further research to unravel the underlying mechanisms and to devise targeted management strategies. These strategies aim to promote the resistance of native weed communities and mitigate the negative effects of invasive weed species in disturbed environments. By delving deeper into these insights, we can gain an understanding of the ecological dynamics within disturbed ecosystems and develop valuable insights for the management of invasive species, and to restore long‐term ecosystem sustainability.

“…Insect survival is also associated with a wide range of microorganisms ( Borgström et al, 2017 ; Agrawal et al, 2018 ). These microbes could act as a disease-causing pathogen or playing a role in insect defense, detoxification, or digestion of food ( Chen et al, 2016 ; Li et al, 2022 ). Microorganisms of herbivorous insects have also been found to be present in plants.…”

IntroductionTraditional chemical control methods pose a damaging effect on farmland ecology, and their long-term use has led to the development of pest resistance.MethodsHere, we analyzed the correlations and differences in the microbiome present in the plant and soil of sugarcane cultivars exhibiting different insect resistance to investigate the role played by microbiome in crop insect resistance. We evaluated the microbiome of stems, topsoil, rhizosphere soil, and striped borers obtained from infested stems, as well as soil chemical parameters.Results and DiscussionResults showed that microbiome diversity was higher in stems of insect-resistant plants, and contrast, lower in the soil of resistant plants, with fungi being more pronounced than bacteria. The microbiome in plant stems was almost entirely derived from the soil. The microbiome of insect-susceptible plants and surrounding soil tended to change towards that of insect-resistant plants after insect damage. Insects’ microbiome was mainly derived from plant stems and partly from the soil. Available potassium showed an extremely significant correlation with soil microbiome. This study validated the role played by the microbiome ecology of plant–soil-insect system in insect resistance and provided a pre-theoretical basis for crop resistance control.
