摘要: 为了解徽水河流域大型底栖动物群落结构的季节动态及构建机制,于2021年10月(秋季)、12月(冬季)、2022年4月(春季)和8月(夏季)对徽水河流域开展系统性调查。4个季节共采集底栖动物5门8纲73科168种,其中春季、夏季、秋季和冬季的物种数分别为85、77、82和82种。单因素相似性分析(ANOSIM)和非度量多维尺度分析(NMDS)结果显示:徽水河底栖动物群落结构在季节动态上存在显著差异。典范对应分析(CCA)表明不同季节影响底栖群落结构变化的关键环境因子不尽相同。变差分解分析显示环境过滤作用在徽水河春季、秋季和冬季底栖动物群落构建过程中占主导,空间因子在高水文连通性的夏季中影响更加明显,表明由高扩散率引起的质量效应在夏季底栖动物群落聚合中起决定性作用。该研究可为皖南山区河流水生生物多样性评估和环境监测提供重要的基础参考。

Abstract: To systematically understand the seasonal dynamics and assembly mechanism of macroinvertebrate community in Huishui River, an investigation was carried out in October (autumn) and December (winter) 2021, April (spring) and August (summer) 2022. The Huishui River supports a high array of macroinvertebrate diversity. A total of 168 taxa were identified, belonging to 8 classes and 73 families. The numbers of macroinvertebrate species in spring, summer, autumn and winter were 85, 77, 82 and 82, respectively. Analysis of similarities (ANOSIM) and nonmetric multidimensional scaling analysis (NMDS) showed that the macroinvertebrate community structure in Huishui River differed significantly among seasons. Canonical correspondence analysis (CCA) showed that the environmental factors affecting the macroinvertebrate community structure were different in the four seasons. Environmental filtering appeared to be key process in structuring macroinvertebrate assemblages in spring, autumn and winter, while the spatial processes played a leading role in summer. This study provides an important scientific reference for the seasonal dynamics of the macroinvertebrate community structure, biodiversity assessment and environmental monitoring in the mountainous streams of southern Anhui Province.
