Abstract

Seasonal variation in community assembly influences biodiversity patterns, yet its dynamics under monsoon-driven hydrology remain underexplored in subtropical mountain streams. We applied the Elements of Metacommunity Structure (EMS) framework and variation partitioning to assess seasonal shifts in benthic macroinvertebrate communities across dry, normal, and wet phases in a subtropical monsoon-driven mountain stream. Assembly patterns transitioned from Quasi-Clementsian (dry season) to Clementsian (normal flow) and Nested structure (wet season). Deterministic environmental filtering—mediated by water temperature, dissolved oxygen, conductivity, water depth, and flow velocity—dominated during dry and intermediate phases. Conversely, stochastic dispersal (mass effects) prevailed during high-flow monsoon periods, driven by enhanced connectivity. By quantifying the hierarchical balance between deterministic and stochastic drivers, our study advances understanding of how hydrological seasonality structures metacommunities. These findings underscore the importance of integrating intra-annual hydrological variability into stream biodiversity assessments and management frameworks.

亚热带季风驱动的山溪中底栖大型无脊椎动物群落群落的季节动态。

亚热带山地河流群落群落的季节变化影响着生物多样性格局，但其在季风驱动水文条件下的动态变化尚未得到充分研究。应用元群落结构（EMS）框架元素和变异划分方法，对亚热带季风驱动的山溪中底栖大型无脊椎动物群落在干燥、正常和湿润阶段的季节变化进行了评估。装配模式由准Clementsian（旱季）过渡到Clementsian（正常流）和巢式结构（雨季）。确定性环境过滤——由水温、溶解氧、电导率、水深和流速介导——在干燥和中间阶段占主导地位。相反，在高流量季风期，由于连通性增强，随机扩散（质量效应）盛行。通过量化确定性和随机驱动之间的层次平衡，我们的研究促进了对水文季节性如何结构元群落的理解。这些发现强调了将年度水文变异纳入河流生物多样性评估和管理框架的重要性。

期刊介绍： Ecology and Evolution is the peer reviewed journal for rapid dissemination of research in all areas of ecology, evolution and conservation science. The journal gives priority to quality research reports, theoretical or empirical, that develop our understanding of organisms and their diversity, interactions between them, and the natural environment. Ecology and Evolution gives prompt and equal consideration to papers reporting theoretical, experimental, applied and descriptive work in terrestrial and aquatic environments. The journal will consider submissions across taxa in areas including but not limited to micro and macro ecological and evolutionary processes, characteristics of and interactions between individuals, populations, communities and the environment, physiological responses to environmental change, population genetics and phylogenetics, relatedness and kin selection, life histories, systematics and taxonomy, conservation genetics, extinction, speciation, adaption, behaviour, biodiversity, species abundance, macroecology, population and ecosystem dynamics, and conservation policy.
