As an important component of aquatic ecosystems, benthic animals are sensitive bioindicators for evaluating water pollution. In this study, we investigated the diversity macrobenthic communities and analyzed pivotal environmental factors affecting alterations in East Taihu Lake. This analysis was augmented by controlled laboratory simulation experiments designed to elucidate validate responses critical indicator species within various functional zones shifts. study shows:(1) Bellamya purificata, Limnodrilus Tubifex were dominant on a year-round scale. Water depth most factor communities;(2) Simulation revealed that growth condition Bellamya significantly worse simulated entrance area than original enclosure aquaculture wetland areas.

Abstract Submerged macrophytes can overgrow and negatively affect freshwater ecosystems. This study aimed to investigate the use of chlormequat (CQ) regulate submerged Vallisneria natans growth as well its impact on microbial community epiphytic biofilms. V. height under CQ dosages 20, 100, 200 mg/L decreased within 21 days by 12.57%, 30.07%, 44.62%, respectively, while chlorophyll content increased 1.94%, 20.39%, 38.83%. At 100 mg/L, reduced diversity bacteria in biofilm attached leaves but eukaryotic community. strongly inhibited Cyanobacteria; compared with control group, treatment group experienced a significant reduction from 36.54% 2.61%. Treatment significantly Gastrotricha Rotifera, two dominant phyla eukaryotes leaf biofilm, reducing their relative abundances 17.41% 6.48%, respectively. changed correlation network. The exhibited lower modularity (2.012) (2.249); however, central network treated contained higher number genera (13) than (4), highlighting significance results obtained this provide invaluable scientific context technical understanding pertinent restoration aquatic Practitioner Points Chlormequat plant content. bacterial diversity. affected bacterial‐fungal association networks
