Abstract Urbanization significantly impacts the community structure of aquatic organisms and poses a major threat to river biodiversity. However, extent which urbanization is linked homogenization microbial communities underlying mechanisms remains poorly understood. In this study, we investigated bacterial archaeal from cities neighboring natural rivers across network located in Qinling Mountains, Northwest China, further alpha beta diversity patterns influenced by urbanization. We found that influx urban non-point source pollutants created eutrophic condition, enhanced populations. Meanwhile, rapid tends decrease overall habitat heterogeneity, imposed stronger homogeneous selection caused biotic homogenization. The can be attributed modulating generalist/specialist species invasion nonnative species. For instance, had greater proportion fast-growing bacteria, algae, nitrifiers, PAH-degrading pathogens, fecal bacteria antibiotic-resistant than ecosystems. Overall, leads more uniform biosphere, causing extinction unique local subsequent regional pool.

Abstract Different microbial communities are impacted disproportionately by environmental disturbances. The degree to which a community can remain unchanged under disturbance is referred as resistance 1 . However, the contributing ecological factors, infer community’s unknown. In this study, impact of historical stability on phenomena and shocks was investigated. Three separate methanogenic bioreactor consortia, were subjected varying degrees stability, displayed different levels an organic loading rate (OLR) shock sampled. Their composition assessed using high throughput sequencing 16S rRNA genes assembly based metagenomics. effect instability such assembly, niche breadth rare biosphere in context each reactor’s demonstrated OLR shock. Additionally, metagenome assembled genomes analysed for functional effects prolonged stability/instability. system more experienced temporal variation beta diversity proliferation specialists, with abundant two component regulatory systems. This susceptible deterministic lower resistance, indicating that experiencing longer term (e.g. variations pH or temperature) less able resist large disturbance.

Abstract Microorganisms dominate marine environments in the polar oceans and are known to harbor greater diversity abundance than was once thought, yet, little is about their biogeographic distribution patterns sediments at a broad spatial scale. In this study, we conducted extensive sampling of along latitudinal transect spanning 2500 km from Bering Sea Arctic Ocean investigate geographical bacteria, archaea, fungi. Our findings revealed that community similarities bacteria fungi decay similar rates with increasing distance (slope: −0.005 −0.002), which much lower rate archaeal communities −0.012). Notably, microbial richness composition showed significant differences region 75−80°N compared other regions 60−75°N. Salinity, temperature, pH, ammonium nitrogen, total organic carbon key factors significantly affect variations. Furthermore, bacterial co‐occurrence networks more complex interactions but modularity fungal counterparts. This study provides crucial insights into will be critical for better understanding global ecological functions.

The epiphytic bacteria in aquatic ecosystems, inhabiting a unique ecological niche with significant function, have long been the subject of attention. Habitat characteristics and plant species are believed to be important controlling assembly bacteria. However, underlying principle governing bacterial community on macrophytes is far from clear. In this study, we systematically compared diversity composition both different habitats where they were attached. Results suggested that neither nor habitat had effect independently, indicating was correlated geographical distance individual macrophytes. Furthermore, almost all abundant taxa shared between lake regions or macrophyte species, most belonged Proteobacteria Firmicutes. Our results demonstrated competitive lottery model may explain pattern colonization submerged surfaces. This research could provide new perspective for exploring plant-microbe interaction systems evidence as mechanism best explaining
