摘要
Knowledge about the spatial and temporal scales of both habitat use and the functional significance of different adaptations is essential for an understanding of the population dynamics of invertebrate assemblages. This fundamental knowledge is not only interesting from an academic point of view, but is sorely lacking and needed in the field of restoration ecology. Many species are threatened due to degradation. Knowing what environmental conditions are needed dtLring the life cycle of these species is important in the design of restoration measures which aim to lift existing bottlenecks for threatened species. To assess the relative importance of water type and microhabitat in structuring the invertebrate assemblage during different seasons, invertebrates were sampled in three water bodies differing in trophic level and acidity. Different parts within a water body （microhabitats） were sampled separately and each water body was sampled in all four seasons. Results show that water body is an important factor structuring the invertebrate assemblage early in the season, whereas microhabitat became more important later in the season. Structural complexity of microhabitats was related to the type of locomotion employed by invertebrates. Seasonal differences could be related to population dynamics （reproduction, mortality）. Moreover, fluctuations in resource availability were expected to differ between the water bodies, with highest fluctuations in the eutrophic water body and with fluctuations becoming less predictable later in the season. This was confirmed by the data： species synchronization to pulses in food availability was strongest in the eutrophic water body. Moreover, synchronization was strongest in summer, while in autumn waters were invaded by dispersive species. Based on these results a synthesis is presented on the functioning of the different waters during the different seasons.
产地使用的空间、时间的规模和不同改编的功能的意义的知识为无脊椎的集合的人口动力学的理解是必要的。这基本知识从一个学术观点有趣不仅，但是疼痛地在恢复生态学的地里正在缺乏并且需要。Manyspecies 由于降级被威胁。知道什么环境条件在种类是的这些的生活周期期间被需要在试图为威胁的种类提起存在瓶颈的恢复措施的设计重要。在在不同季节期间组织无脊椎的集合估计水类型 andmicrohabitat 的相对重要性，无脊椎动物在在营养水平和酸味不同的三水身体被取样。在水身体(微产地) 以内的不同部分独立被取样，每水身体在所有四个季节被取样。结果证明那水身体是在季节早组织无脊椎的集合的一个重要因素，而微产地以后在季节变得更重要。微产地的 Structuralcomplexity 与无脊椎动物采用的运动的类型有关。季节的差别能与人口动力学有关(复制，死亡) 。而且，在资源可获得性的变化被期望在水身体之间不同，以后在季节与在发育营养正常促进剂水身体的最高的变化并且与变化变得不太可预言。这被数据证实：到在食物可获得性的脉搏的种类同步在发育营养正常促进剂水身体是最强壮的。而且，同步在夏天是最强壮的，当在秋天水被散种类入侵时。把结果基于这些合成在在不同季节期间不同的水工作上被介绍。
