Bacteria play a crucial role in pollutant degradation, biogeochemical cycling, and energy flow within river ecosystems. However, the underlying mechanisms governing bacterial community assembly their response to environmental factors at seasonal scales subtropical rivers remain poorly understood. In this study, we conducted 16S rRNA gene amplicon sequencing on water samples from Liuxi River investigate composition, processes, co-occurrence relationships of communities during wet season dry season. The results demonstrated that differences hydrochemistry significantly influenced composition communities. A more heterogeneous structure increased alpha diversity were observed Water temperature emerged as primary driver for changes Dispersal limitation predominantly governed assembly, however, season, its contribution due decreased immigration rates. Co-occurrence network analysis reveals mutualism played prevailing shaping structure. Compared exhibited higher modularity, competition, keystone species resulting stable Although displayed distinct variations, Proteobacteria Actinobacteria consistently abundant maintaining both seasons. Our findings provide insights into how respond changes, uncovering rivers, which are effective management conservation riverine

Ultrasonic treatment and optimal cultivation techniques are both conducive to the high yield of super rice in South China. Many previous studies have shown that increase intercepted photosynthetically active radiation (IPAR) use efficiency (RUE) is an important reason for yield. Field experiments were conducted over two years evaluate effects IPAR RUE on under different treatments (CK: conventional technique without ultrasonic treatment; T1: with T2: rice-specific T3: treatment), representative varieties, Wufengyou-615 (WFY) Jingnongsimiao (JNSM) during late seasons The could significantly yield, which was (p < 0.01) positively correlated panicle number, grain-filling rate, aboveground total dry weight. higher grain depended more highly mid-tillering stage maturity stage. results multiple-regression models also showed contributions significant 0.01). Conclusively, contributed a lot progress fewer times topdressing It worth further studying how reasonably improve high-RUE varieties through other means.
