This study, concerning the epigeic fauna of carabid beetles (Coleoptera; Carabidae), was conducted in the north-east of Poland, in an area which is part of the Dąbrówka Forest Subdistrict and has been included in the “Small water retention program for the Province of Warmia and Mazury in 2006–2015”. The purpose of the study was to assess the impact of the water retention implemented within the framework of the above program on assemblages of ground beetles. These insects are highly sensitive to any anthropogenically induced transformations. This analysis was based on the interactions among the analyzed insects caused by changes occurring in their habitat. During the 3-year study, 5,807 specimens representing 84 species were captured. The water storage had a significant influence on the structure of the Carabidae assemblages. Before the earthworks were constructed for the project, the beetle assemblages had comprised a large group of xerophilous species, whereas after the small retention reservoirs had been created, an increase in the contribution of hygrophilous species was noticed. The results indicate that the retention works cause alterations in the water and environmental conditions of the habitats, and thereby effect changes in the composition of Carabidae assemblages. Moreover, modification in water relations within a habitat causes long-term changes in the structural and functional diversity of the beetles.

地面甲虫（鞘翅目；Carabidae）作为森林栖息地因保水量增加而持续变化的指标

这项关于甲虫（鞘翅目；Carabidae）的表观动物群的研究是在波兰东北部的一个地区进行的，该地区是 Dąbrówka 森林分区的一部分，并已被列入“小水保留计划” 2006-2015 年的瓦尔米亚省和马祖里省”。该研究的目的是评估在上述计划框架内实施的保水对地面甲虫组合的影响。这些昆虫对任何人为诱导的转化高度敏感。该分析基于所分析的昆虫之间由于栖息地发生变化而引起的相互作用。在为期 3 年的研究中，共捕获了 84 个物种的 5,807 个标本。储水量对 Carabidae 组合的结构有显着影响。在为该项目建造土方工程之前，甲虫组合由一大群干旱物种组成，而在创建小型蓄水库后，人们注意到喜湿物种的贡献有所增加。结果表明，保留工程会改变栖息地的水和环境条件，从而影响 Carabidae 组合的组成。此外，栖息地内水关系的改变会导致甲虫结构和功能多样性的长期变化。结果表明，保留工程会改变栖息地的水和环境条件，从而影响 Carabidae 组合的组成。此外，栖息地内水关系的改变会导致甲虫结构和功能多样性的长期变化。结果表明，保留工程会改变栖息地的水和环境条件，从而影响 Carabidae 组合的组成。此外，栖息地内水关系的改变会导致甲虫结构和功能多样性的长期变化。
