Phytoplankton communities typically comprise a few dominant species and numerous rare ones, but their responses to seasonal precipitation changes remain poorly understood. To address this knowledge gap, investigations were conducted on the environmental conditions phytoplankton in Lalin River Basin during dry rainy seasons. Structural equation modeling co-occurrence network analysis then utilized explore assembly processes of following heavy rainfall event. Our results showed events significantly altered community composition diversity (p < 0.05). Furthermore, stochastic process was particularly pronounced for (i.e., 4.44%, p 0.01). Co-occurrence revealed that increasing enhances complexity stability ecological networks. Additionally, relative importance decreases, while increases. This phenomenon can be described as weakening so-called “Matthew effect” ecosystem. In summary, our shed light ecology agricultural rivers reveal how influence formation sub-communities structure

Liangzi Lake, a typical shallow lake in the middle reaches of Yangtze River, is important for water resource and biodiversity conservation. With development urbanization, anthropogenic activities have posed serious threats to quality Lake. To assess aquatic ecosystem health structure, environmental response, interactions plankton were investigated 2022 2023. The results indicated that temperature was pivotal factor regulating dynamics, with assemblage patterns predominantly shaped by phytoplankton species, which Bacillariophyta spring Chlorophyta summer. In terms phytoplankton, dissolved oxygen N:P ratio significantly affect cyanobacteria distribution. high biomass abundance summer highlight potential risk harmful algal blooms. contrast zooplankton exhibited enhanced resilience changes surrounding environment. Rotifera dominant group both biomass. Most core genera jointly identified eDNA metabarcoding microscopical analysis, had advantages revealing higher diversity. However, some taxa among rotifers such as Liliferotrocha only using analysis. Therefore, combination methods recommended better understand structuring mechanisms assemblages ecosystems.

Mastering the characteristics of planktonic microbial communities under influence basin-scale environmental factors can provide scientific basis to develop more targeted protection and restoration measures. Here, an DNA metabarcoding technology was applied investigate phytoplankton microzooplankton simultaneously along whole basin Jialing River, one most important rivers in Southwest China with large scale altitude gradient water temperature discrepancy. Along river-way from upper lower reach, upward trend richness both observed significant positive negative correlations (Spearman correlation, p &lt; 0.05), respectively. Significant variations their compositions river were also uncovered Chrysophyta Foraminifera potential keystones recognized by co-occurrence network analysis. Additionally, exponential distance-decay similarities detected for microzooplankton, which stronger phytoplankton. Based on results variation partitioning analysis null model, governed selection than those microzooplankton. Furthermore, showed a declining complexity stability reaches. These findings could serve establish investigation multiple artificial modifications.
