ABSTRACT We determined seasonal and spatial variation of zooplankton and their correlation with environment variables in a subtropical lake of the Himalayas. Thirty-eight species of zooplankton were identified, of which, 38.0% belonged to rotifera, 26.3% to cladocera, and 15.7% to copepoda. Nitrogen nutrients, total organic matter (TOM), and clay particles significantly influenced on the distribution pattern of zooplankton. Non-metric multidimensional scaling analysis showed homogeneous assemblages of dominant zooplankton species except Chydorus gibbus which has wider range of niche partitioning. Turbidity formed by suspended materials facilitated better avoidance of larger zooplankton like Daphnia similis from predators. Sedimentary silt particles influenced on the assemblages of sensitive species such as Tropocyclops prasinus, Asplanchna priodonta and Colurella obtuse. Changes within the land-use pattern in the catchment of the central Himalayan lakes either directly or indirectly impact on the distribution of zooplankton community.

印度喜马拉雅中部高海拔湖泊跨环境变量的浮游动物群落结构

摘要 我们确定了喜马拉雅亚热带湖泊中浮游动物的季节和空间变化及其与环境变量的相关性。共鉴定出浮游动物38种，其中轮虫类占38.0%，枝角类占26.3%，桡足类占15.7%。氮养分、总有机质（TOM）和粘土颗粒对浮游动物的分布格局有显着影响。非度量多维标度分析表明，除了具有更广泛生态位划分的长臂海藻外，优势浮游动物物种的组合均一。悬浮物质形成的浑浊有助于更好地避免捕食者像水蚤这样的大型浮游动物。沉积淤泥颗粒影响敏感物种的组合，如 Tropocyclops prasinus、Asplanchna priodonta 和 Colurella obtuse。喜马拉雅中部湖泊流域土地利用格局的变化直接或间接影响浮游动物群落的分布。
