The effects of various aquatic habitats on the abundance, species richness, diversity and taxonomic distinctness of Odonata were studied. The impact of environmental factors and living conditions in lentic habitats were expressed by the composition of coenoses, on the evaluation we used the Dragonfly Biotic Index. The positive effects of habitat heterogeneity on biodiversity are well known, but it is not clear how the diversity of studied and ecologically important taxa, such as odonates, may vary in different water reservoirs. We investigated how Odonata community metrics (composition, abundance, diversity and environmental compatibility) differ in lentic water: ponds, fishponds, excavation of mineral material and in marshlands, where biodiversity plays an important role. Using an entomological mesh, we took samples in the south-western part of Slovakia in six geo-morphological units at 54 study sites during four years. This study detected distinct odonates assemblage variations among habitats and heterogeneity among gradients. Wide ranges of microhabitats with different environmental properties create appropriate conditions for living span of them. Surprisingly, the highest species richness was recorded in the excavation of mineral materials habitats. Stagnicolous Odonata species correlated (CCA) with the habitats of excavation of mineral material and marshlands; showed links to the littoral vegetation and dense vegetation cover. While the euryecious species have been linked to the ponds and fishponds; and correlated with the water body size. It seems to be degraded habitats are not so much suitable for rare and endangered species, but to preserve the biological value of the environment and for the existence of the high abundance and species richness of odonates.

斯洛伐克(中欧)慢水库中不同的蜻蜓组合变化

研究了各种水生生境对蜻蜓目丰富度、物种丰富度、多样性和分类独特性的影响。环境因素和生活条件的影响通过 coenoses 的组成来表示,我们使用蜻蜓生物指数进行评估。栖息地异质性对生物多样性的积极影响是众所周知的,但尚不清楚研究的和具有重要生态意义的分类群的多样性,如齿科动物,在不同的水库中如何变化。我们调查了 Odonata 群落指标(组成、丰度、多样性和环境兼容性)在静水水域中有何不同:池塘、鱼塘、矿物材料的挖掘以及在生物多样性发挥重要作用的沼泽地。使用昆虫学网格,四年间,我们在斯洛伐克西南部 54 个研究地点的 6 个地貌单位采集了样本。这项研究检测到栖息地之间不同的齿类组合变化和梯度之间的异质性。具有不同环境特性的各种微生境为它们的生存期创造了适当的条件。令人惊讶的是,矿物材料栖息地的挖掘记录了最高的物种丰富度。Stagnicolous Odonata 物种与矿物材料和沼泽地挖掘的栖息地相关联(CCA);显示了与沿海植被和茂密植被覆盖的联系。虽然广袤的物种已与池塘和鱼塘联系在一起;并与水体大小相关。似乎退化的栖息地不太适合稀有和濒危物种,
