“…In the urban river areas, proportion of the archaea exhibited 1.58 times higher than those in natural river, and archaeal Chao1 richness and Shannon diversity exhibited 1.47 and 2.36 times higher than that in the natural river, respectively. This finding is similar to previous study revealed that in a high-contamination zone, archaeal Chao1 richness and Shannon diversity exhibited substantial increases, approximately 1.81 and 1.56 times higher than those in a low-contamination zone, respectively (Yang et al 2022). Krzmarzick et al (2018) proposed that archaea have demonstrated a notable capacity for enduring harsh environments, leading to the possibility that numerous archaeal species possessing exceptional adaptability to severe anthropogenic pollution could flourish in urban river environments (Krzmarzick et al 2018).…”

“…Previously, the investigation on the impacts of geographic distances and environmental conditions on microbial community assembly has been a research hotspot in river ecology [86, 87]. In large scale watersheds such as Yangtze River and Tingjiang River, geographic distance was proven key factor governing community succession [10, 90, 91]. However, we observed microbial communities in the natural river sites had a steeper DDR slope between sampled sites than those in urban sites (Fig.…”

“…However, in recent decades, human activities such as rapid urbanization, industrialization and agriculture has discharged multiple anthropogenic contaminants and non-native (exotic) microorganisms into the river through industrial discharge, agricultural runoff, and municipal sewage (Wang et al 2012, Beattie et al 2020). These contaminants can be either organic (e.g., antibiotics, polycyclic aromatic hydrocarbons, fertilizers, pesticides, manure) (Singh et al 2019, Patel et al 2020, Liu et al 2023, Xu et al 2023) or inorganic contaminants (e.g., nitrate, phosphorus, heavy metal) (Pruden et al 2012, Manyi-Loh et al 2016, Yang et al 2022). At the same time, river sediments often act as the recipients of reservoirs for contaminants influenced by human activity inputs.…”

Rivers have been a preferred location for human settlements throughout history. Comparing the bacterial and archaeal communities in highly human-impacted areas and undisturbed pristine nature reserves could expand our understanding of the mechanisms of river ecosystem responses to environmental changes resulting from anthropogenic contaminants. In this study, 24 urban and 28 nature reserve river sediment samples were collected in a highly connected river network spanning ∼400 km, and their geobiochemistry profiles and microbial populations were investigated. The data showed that human activities had discharged significant amounts of nutrients and even exotic microorganisms into the river, resulting in significant changes in the microbial community and potential function, including an increase in pathogens, antibiotic-resistant bacteria and PAHs-degrading bacteria. Environmental selection was more important than dispersal limitation in the river network, and environmental factors were the best predictors of the variation observed between microbial communities. Specifically, homogeneous selection imposed by anthropogenic pollution stress lead to higher microbial diversity but a lower habitat niche breadth in urban river areas. Collectively, the study suggests that community composition and diversity dynamics of the river network are not random but driven by environmental factors. The natural buffering capacity of highly connected river network ecosystems is unable to fully resist the impacts from human activity pressures.HighlightIncreased bacterial and archaeal diversity was provoked by multiple anthropogenic pollutants in the river network.Sewage discharge and high nitrogen loadings reshaped the microbial composition in urban areas. Homogeneous selection imposed by anthropogenic pollution stress primarily shaped assembly of bacterial and archaeal.Environmental factors contribute more to the microbial variation than dispersal in the study area.
