The appropriate volume of filtered water samples is crucial for accurately reflecting microbial community characteristics. Previous research has shown that changes in sample volumes significantly affect bacterial diversity and the relative abundance dominant taxa marine environments. However, specific impact on freshwater structure, particularly eukaryotic microorganisms, remains unclear. To address this gap, we collected from eutrophic Lake Taihu mesotrophic Bosten. We through 0.2 μm filters using ranging 0.1 to 2 L 3.2 Analysis 18S rRNA gene amplicons revealed variations affected diversity, composition microorganisms. In light these findings, recommend a approximately aquatic ecosystems 0.8 analyses. These recommendations underscore importance selecting ensure representative reliable results study microorganisms ecosystems.

Aggregation and co-occurrence patterns of microbial communities are the key scientific issues in lake ecology. To explore mechanisms ecological assembly community succession this unique habitat, 16 samples were collected from eight sites Wuliangsuhai Lake. Second-generation DNA sequencing was applied to reveal spatial dynamics bacterial structure distribution across two environmental media nutrient-rich shallow grassland elucidate characteristics network. This study also examined effects filtering biological interactions on formation maintenance composition diversity. The results highlight habitat heterogeneity composition, with no discernible latitudinal diversity patterns. causal analysis identified electrical conductivity, pH, total nitrogen, phosphorus as primary factors driving changes water sediment grass-type lakes, TN being driver. CL500-3 a pollution-tolerant species aquatic environments. g__norank_f_Verrucomicrobiaceae exhibited significant distance decay pattern, higher turnover rate than sediment. Co-occurrence network revealed greater complexity stability communities, three potential keystone species, water. neutral null model indicated that more susceptible dispersal limitation, whereas complex increased role deterministic processes construction. proposed division plant regions freshwater lakes demonstrated different types, contributing comprehensive understanding shallow-water structure.

Water replenishment is an important measure for maintaining and improving the aquatic environmental quality of lakes. The problems water deterioration shortage can be alleviated by introducing higher quality. However, mechanism in improvement trophic status lakes remains unclear. This study investigated Wuliangsuhai Lake (WLSHL) from 2011 to 2021 collecting seasonal samples conducting laboratory analyses. was found capable significantly lake alleviating eutrophication. It worth noting that single long-term measures have limitations status. whole process divided into three stages according status, namely buffer period, decline stable period. During showed only slight because small amount low proportion higher-quality Yellow River. In with increasing replenishment, River gradually increased, leading most significant degree improvement. increases had little effect on which attributable balance between internal pollutants (lake water-sediment), internal-external water-irrigation return flow + water). On premise quality, eutrophication control as management goal, optimal would approximately 10.58 ×10

Brooks are significant ecological sources and migration channels of material flow as well energy in urban–rural fringes. Despite their significance, the absence monitoring data poses challenges assessing brook pollution risk. Taking Muli Brook an example, a spatiotemporal variability water quality was revealed through sample collection chemistry analysis. We reveal then developed Exposure Index (EPI), verifying its substitution effect Our findings demonstrate downward trend from 2020 to 2022, with exceptions dissolved oxygen (DO) pH. Notably, more severe is observed during spring summer, influenced by seasonal production activities extreme weather events. diminishing disparity near urban areas, cumulative influence upstream pollutants outweighs that surrounding human activities. Stronger associations between risks area EPI were observed, compared those construction land farm land. In conclusion, emerges valuable tool for fringes, offering precise insights into habitat characteristics, especially consistent data.
