This study investigated the spatial and temporal variations of macrobenthos community structure in Yuqu River Basin during dry wet seasons due to environmental factors. quantified independent interactive contributions hydrophysical, hydrochemical, climatic factors through a variance decomposition analysis (VPA). The findings indicate that May (the season), such as water depth, flow velocity, dissolved oxygen, air temperature exhibit relatively minor fluctuations, rendering aquatic environment more stable than rainy season. stability is particularly conducive maintenance macrobenthic species diversity, which especially evident insects with nesting habits, those belonging Trichoptera order (including genera like Glossosoma, Glossosomatidae, Georodes). In contrast, August substantial precipitation alters thermal conditions river, increases raises levels, introduces significant influx organic matter sedimentation. distinctive ecological fosters unique adaptive strategies among organisms. Notwithstanding notable decline diversity this particular phase, there concurrent increase abundance individual organisms, indicative populations’ remarkable capacity swiftly adapt heterogeneity. Research has demonstrated communities within adopt pronounced tactics vary significantly between seasons. During season, these fauna rely heavily on their physical habitat. stark they are compelled navigate cope intricate dynamic changes hydrological chemical characterize presented results uncover sensitive responsiveness seasonal fluctuations high-altitude river systems under diverse stressors. Arthropods, particular, marked sensitivity changes. delves into biodiversity ecosystems, analyzing distribution patterns variation characteristics communities. aims examine how hydroclimatic modulate composition assemblages tributaries principal channels systems, thereby establishing foundational reference for future ecosystem assessments regions.
