Abstract Epiphytic bacteria constitute a vital component of aquatic ecosystems, pivotal in regulating elemental cycling. Despite their significance, the diversity and functions epiphytic bacterial communities adhering to various submerged macrophytes remain largely unexplored. In this study, we employed metagenomic approach investigate function associated with six macrophytes: Ceratophyllum demersum , Hydrilla verticillata Myriophyllum verticillatum Potamogeton lucens Stuckenia pectinata Najas marina . The results revealed that predominant species for each plant type included Pseudomonas spp., Microbacterium Stenotrophomonas rhizophila Multiple comparisons linear discriminant analysis effect size indicated significant divergence community composition among macrophytes, 0.3–1% uniquely identified. richness S. significantly differed from both C. H. although no differences were observed evenness. Functionally, notable variations relative abundances genes carbon, nitrogen, phosphorus cycling within on macrophyte hosts. Among these communities, exhibited enrichment related 3-hydroxypropionate bicycle nitrogen assimilation, translocation, denitrification. Conversely, M. showcased linked reductive citric acid cycle (Arnon-Buchanan cycle), pentose phosphate (Calvin polyphosphate degradation, organic metabolism. summary, our findings offer valuable insights into leaves, shedding light roles lake ecosystems.

Coal mining subsidence lakes are classic hydrologic characteristics created by underground coal and represent severe anthropogenic disturbances environmental challenges. However, the assembly mechanisms diversity of microbial communities shaped such environments poorly understood yet. In this study, we explored aquatic bacterial community ecological processes in during winter summer using 16S rRNA gene sequencing. We observed that clear structure was driven seasonality more than habitat, α-diversity functional were significantly higher (p < 0.001). Canonical correspondence analysis indicated temperature chlorophyll-a most crucial contributing factors influencing season variations lakes. Specifically, explained 18.26 14.69% variation, respectively. The variation deterministic but dominated stochastic summer. Compared to winter, network exhibited a average degree, modularity, keystone taxa (hubs connectors network), thereby forming highly complex stable structure. These results illustrate heterogeneity provide new insights into revealing effects seasonal succession on lake ecosystems.

Introduction Bacterial communities play crucial roles in the functioning and resilience of aquatic ecosystems, their responses to water pollution may be assessed from ecological niches. However, our understanding such response patterns underlying mechanisms remains limited. Methods In this study, we comprehensively investigated effects on bacterial structure assembly within different niches, including water, sediment, submerged plant leaf surfaces, using a 16S high-throughput sequencing approach. Results Ecological niches had greater impact community diversity than pollution, with distinct enrichment unique dominant phyla This disparity extends general reduction α-diversity observed excluding surfaces. Additionally, changes composition should correlated predicted functions, given functions related biogeochemical cycling surface Moreover, study revealed diverse interaction among characterized by relatively simply associations sediments intricate or interconnected networks Furthermore, stochastic processes dominated column, whereas selective screening roots events increased deterministic processes. Discussion Overall, emphasizes importance shaping pollution. These findings improve complicated microbial have implications for ecosystem health.

Abstract Background Deciphering the assembly rules of microbial communities is vital for a mechanistic understanding general principles driving microbiome structures and functions. In this study, null modeling-based framework was implemented to infer bacterial community in oat silages harvested southern China starting from grain-filling stage through full ripening. Results Most displayed “inferior” or “very inferior” fermentation quality. The qualities tended further decrease with delay harvest. Lactobacillus , Pediococcus unclassified_f_Enterobacteriaceae Hafnia–Obesumbacterium constituted predominated genera silages. Delaying harvest increased proportions . Null model analysis revealed that stochastic processes were primary contributor rare subcommunity during silage fermentation. succession abundant controlled both by deterministic processes. Deterministic processes, more specifically, heterogeneous selection, prominent bacteria Linear regression indicated important roles DM, WSC pH subcommunity. Conclusion This ecological perspectives, controlling silage, providing new insights into mechanisms underlying construction community. Graphical
