ABSTRACT Biofilms play an important role in nutrient and food web dynamics of shallow aquatic ecosystems. Multiple prokaryotic eukaryotic microorganisms within biofilms interact with each other to shape the community structure their functional attributes. However, there is no clear understanding varied patterns biofilm versus microbial abundances, diversities communities, which limit our how communities functions hypereutrophic urban river ecosystems are changing. To elucidate properties controls on a river, we conducted one‐year study investigate seasonal water‐depth variations abundance/biomass, diversity communities. The were determined by high‐throughput sequencing based 16S 18S rRNA gene. Sequencing revealed that Proteobacteria , Bacteroidota Cyanobacteria three dominant phyla Rotifera Chlorophyta Annelida Bacillariophyta four Biofilm bacterial abundance depended mainly water temperature, whereas algal biomass correlated rotifer grazing light levels. Prokaryotic had higher species richness than Species displayed significant minima for winter summer, linked temperature grazing, respectively. Variations composition related ammonia concentration co‐occurrence network analysis suggested could considerably decrease complexity groups, especially key formation stable networks. There differences heterogeneity composition. Our findings indicate level, nutrients (especially ammonia) appreciably contribute changes abundance, river. These increase characteristics rivers provide insights pollution remediation strategies.

ABSTRACT Microbial communities in riverine hyporheic zones provide essential ecosystem services. However, the mechanisms whereby they respond to water exchange under different habitat stress conditions remain poorly understood. Therefore, investigating impact of on microbial community composition and its potential ecological function is essential, particularly seasonal rivers northern China. To elucidate structure zone sediment response environmental fluctuations, we examined associations by performing situ falling‐head permeameter tests eDNA techniques. The primary findings were as follows: (1) We detected variations spatial distribution patterns streambed hydraulic conductivity (range, 0.055–3.490 m/day) vertical fluxes 1.886–342.0 mm/day) among monitoring stations. (2) displayed compositional similarities heterogeneity. Stations with limited characterised reduced species diversity. (3) Prokaryotes showed better modularity characteristics higher stability functional diversity than eukaryotic communities. (4) Differences abundance metabolism genetic functions observed habitats. This study emphasises significance local hydrological (such downwelling) maintaining elements acting hotspots for within zone. heterogeneity governing can explain abundance, biogeochemical processes microorganisms this
