The threats to small urban streams lead to a decrease in their water quality and dysregulate their ecological balance, thereby affecting the biodiversity and causing degradation of indicators that determine the ecological potential. The aim of our study was to determine the impact of abiotic conditions induced by intensive human activity on the community structures of invertebrates (zooplankton and macroinvertebrates) in the small urban stream Bukowka in the Szczecin agglomeration (NW Poland). This stream exhibits the same characteristics as a large river, in which the mass of live organic matter increases with their length. The composition of invertebrates (zooplankton and macroinvertebrates) was strongly influenced by the changes caused by humans in the stream bed. The construction of small reservoirs and bed regulation in this small urban streams had a similar effect on the quality of the water and ecological potential as in large rivers, but at a lower scale.

无脊椎动物结构的空间变化作为城市小河流河床和集水区强烈人类活动的一个因素

对城市小溪流的威胁导致其水质下降和生态平衡失调，从而影响生物多样性并导致决定生态潜力的指标退化。我们研究的目的是确定由密集的人类活动引起的非生物条件对什切青聚集区（波兰西北部）的小城市河流 Bukowka 中无脊椎动物（浮游动物和大型无脊椎动物）群落结构的影响。这条溪流表现出与大河相同的特征，其中活有机物的质量随着其长度的增加而增加。无脊椎动物（浮游动物和大型无脊椎动物）的组成受到人类在河床中引起的变化的强烈影响。
