我们研究了在洪水事件中的温带洪泛区的水体（欧盟，帕拉，近河和结合水体）的浮游动物组合的结构和种群动态。在这里，我们报告的差异，这些水体的物种组成的两个阶段的洪水脉冲：上升与后退。在消退期间，较大的和第二纪物种的比例增加。这些河漫滩水体的浮游动物组合的相似性增加，在上升和下降的消退期间。除真河相外，各类型水体浮游动物群落的物种丰富度、多样性和种群密度值在退水期间均呈上升趋势。轮虫群落的行会比表现出特征性的，但有些模糊的变化。我们的结论是，水文制度影响的结构和动态的浮游动物组合的河漫滩。（© 2011 WILEY-VCH Verlag GmbH & Co. KGaA，魏因海姆）
We studied the structure and population dynamics of zooplankton assemblages in the water bodies (eu-, para-, plesiopotamal and conjunctive water bodies) of a temperate floodplain during flood events. Here we report differences in the species composition of these water bodies in the two stages of flood pulses: rising vs. receding. During the receding period the proportion of larger and tychoplanktonic species increased. Similarity among zooplankton assemblages of these floodplain water bodies increased during the rising and decreased during the receding period. Species richness, diversity and population density values of zooplankton assemblages increased during the receding period in all types of water bodies except the eupotamal. The guild ratio of rotifer assemblages showed characteristic, but somewhat ambiguous changes. We conclude that the hydrological regime affects the structure and dynamics of zooplankton assemblages on the floodplain. (© 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
