The caddisflies (Trichoptera) of calcareous fen habitats, in contrast to those of other peatland types, have been poorly researched. We thus conducted a two-year study in south-eastern Poland encompassing four types of such habitats-drained and undrained fens and water bodies (pools and ditches) located within the fens-in order to define trichopteran reference assemblages (PCoA), indicator species (IndVal analysis), and the drivers (both natural and those associated with landscape management, including area protection) responsible for caddisfly species distribution (CCA). The most important environmental driver was habitat persistence. Distance-based RDA analysis revealed a distinct pattern in the distribution of species with or without diapause along the persistence gradient. Environmental drivers associated with plants were also crucial for both fens and water bodies. The key factor influencing the caddisfly assemblages of pools and ditches was the use and management of the surrounding land, whereas in the fens, it was the level of area protection. Physical and chemical water parameters had no statistically significant impact on the assemblages. Some factors can be modified by humans (e.g., water level regulation, vegetation, and landscape management) to maintain healthy ecosystems for aquatic insects.
与其他泥炭地类型的石蛾相比，钙质沼泽栖息地的石蛾（毛翅目）研究较少。因此，我们在波兰东南部进行了一项为期两年的研究，涵盖了四种此类栖息地——排水和未排水的沼泽以及沼泽内的水体（池塘和沟渠），以确定毛翅目参考群落（主坐标分析）、指示物种（指示值分析）以及负责石蛾物种分布的驱动因素（包括自然因素和与景观管理相关的因素，包括区域保护）（典范对应分析）。最重要的环境驱动因素是栖息地的持久性。基于距离的冗余分析揭示了具有或不具有滞育的物种沿持久性梯度分布的明显模式。与植物相关的环境驱动因素对沼泽和水体也至关重要。影响池塘和沟渠石蛾群落的关键因素是周边土地的利用和管理，而在沼泽中，则是区域保护水平。物理和化学水质参数对群落没有统计学上的显著影响。一些因素可以由人类进行调整（例如水位调节、植被和景观管理），以维护水生昆虫的健康生态系统。
