Type: article
Abstract: Aims: The Yarlung Zangbo River is an important water system in China, and as a high-altitude river in the Tibetan Plateau, its special environmental conditions make its aquatic ecosystem valuable to study.In recent years, studies on the aquatic ecology of the Yarlung Zangbo River have gradually increased, but studies focusing on protozoa are rare.The aim of this study was to explore the community dynamics of protozoa in the middle Yarlung Zangbo River and its driving factors, and to provide basic data and decision-making references for further studies on the Yarlung Zangbo River as well as for the monitoring and conservation of the Tibetan Plateau water environment.Methods: 18S rDNA high-throughput sequencing technology was used to study the protozoa diversity, and the physicochemical factors were measured on site of water bodies at 28 sample sites in the middle reaches of the Yarlung Zangbo River (Qushui County to Pai Town) in July 2021 (wet season).The α diversity of community was analyzed by Shannon diversity index, Simpson diversity index, Pielou evenness index and richness index; the β diversity of community was analyzed by Jaccard difference index; analysis of the interspecific relationships was analyzed by co-occurrence networks; the influence of physicochemical factors on the diversity of the protozoan community was studied by correlation and bioenvironmental (BIOENV) analysis.•研究报告• 杨清等: 雅鲁藏布江中游丰水期原生动物群落多样性及其影响因子 2023年
