Comparison of the spatial distribution and assembly processes between bulk rhizosphere bacterial communities at multiple scales is vital for understanding generation maintenance microbial diversity under influence plants. However, biogeographical patterns underlying mechanisms in sediments aquatic ecosystems remain unclear. Here, we collected 140 sediment samples Phragmites australis from 14 lakeshore zones across a 510-km transect Middle-Lower Yangtze plain. We performed high-throughput sequencing to investigate diversity, composition, these samples. Bacterial exhibited higher alpha but lower beta than those sediment. Both had significant distance-decay relationships, turnover community was strikingly that Despite variable selection dominating sediment, P. enhanced role dispersal limitation governing communities. The relative importance different ecological determining presented distinct increasing or decreasing linearly with an increase scale. This investigation highlights convergent plant surrounding emphasizes on environments over scales. Furthermore, provide preliminary framework exploring scale dependence ecosystems.

The microbiome of the Sinai Desert farming system plays an important role in adaptive strategy growing crops a harsh, poly-extreme, desert environment. However, diversity and function microbial communities under this unfavorable moisture nutritional conditions have not yet been investigated. Based on culturomic metagenomic methods, we analyzed total fourteen rhizosphere soil samples (collected from twelve plants four farms desert), which may provide valuable meaningful guidance for design inoculants.The results revealed wide range taxa, including high proportion novel undescribed lineages. composition differed according to sampling sites, despite similarities or differences floristics. Whereas, functional features microbiomes were significantly similar different although plant hosts themselves different. Importantly, microorganisms involved ecosystem functions are between example nitrogen fixation was prevalent all sample sites while responsible process different.Here, first characterization systems highlight its unexpectedly diversity. This study provides evidence that key with environment conditions, emphasizing importance communities. Furthermore, suggest inoculants be used future agricultural production should select can plant-microorganism interactions already adapted environmental setting.

ABSTRACT Soil water repellency (SWR) significantly impacts infiltration and soil health, influencing ecological processes across various habitats. Although the mechanisms behind SWR remain partially unclear, it is influenced by both biological properties. While several studies have examined in agricultural soils, fewer focused on natural This study examines relationships between properties (electrical conductivity (EC), pH, total carbon (TC)), prokaryotic communities, potential (measured molarity of ethanol droplet test, 60°C pretreatment) 1153 samples spanning 33 habitat types Denmark. Using path model analysis, we show that biotic abiotic factors contribute to SWR. A including EC, TC, community composition (β‐diversity) could explain ~50% variation SWR, with β‐diversity TC being most important Furthermore, reveal distinct variations types, which cover a wide range from not repellent strongly repellent. Prokaryotic α‐diversity was negatively correlated degree found clear gradient highest lowest The divided into five classes, identified 69 genera indicating one or combination potentially be used as indicators research underscores importance microbial communities examining In perspective, observed relations diversity also imply become key biophysical indicator health.

Abstract Soil microbial diversity mediates a wide range of key processes and ecosystem services influencing planetary health. Our knowledge biogeography patterns, spatial drivers human impacts at the continental scale remains limited. Here, we reveal bacterial fungal community distribution in Australian topsoils using 1384 soil samples from diverse bioregions. findings highlight that climate factors, particularly precipitation temperature, along with properties, are primary topsoil biogeography. Using random forest machine‐learning models, generated high‐resolution maps bacteria fungi across Australia. The revealed hotspots, for example, eastern coast, southeastern west coast were dominated by Proteobacteria Acidobacteria. Fungal is strongly influenced precipitation, Ascomycota dominating central region. This study also demonstrated impact modification on underground scale, which significantly increased relative abundance Ascomycota, but decreased Chloroflexi Basidiomycota. variations phyla could be attributed to distinct responses altered environmental factors after modifications. provides insights into microbiota, valuable regional biodiversity assessments monitoring global changes.
