Peat bogs are unique wetland ecosystems of high conservation value all over the world, yet data on the macroinvertebrates (including mayfly assemblages) in these habitats are still scarce. Over the course of one growing season, mayfly assemblages were sampled each month, along with other macroinvertebrates, in the largest and oldest Croatian peat bog and an adjacent stream. In total, ten mayfly species were recorded: two species in low abundance in the peat bog, and nine species in significantly higher abundance in the stream. Low species richness and abundance in the peat bog were most likely related to the harsh environmental conditions and mayfly habitat preferences. In comparison, due to the more favourable habitat conditions, higher species richness and abundance were observed in the nearby stream. Three of the recorded species, from the peat bog, and and from the stream are new records for the Croatian mayfly fauna. Typical Central European life cycle patterns were confirmed for several species (e.g. , , ), while for several others (e.g. , ) some discrepancies were observed. Therefore, these results provide new and valuable information on the ecology of mayflies in peat bog habitats.
泥炭沼泽是全球具有高度保护价值的独特湿地生态系统，但关于这些栖息地中大型无脊椎动物（包括蜉蝣群落）的数据仍然匮乏。在一个生长季节里，每月对克罗地亚最大、最古老的泥炭沼泽及其附近溪流中的蜉蝣群落以及其他大型无脊椎动物进行采样。总共记录了10种蜉蝣：泥炭沼泽中有2种数量稀少，溪流中有9种数量显著更多。泥炭沼泽中物种丰富度和数量较低很可能与恶劣的环境条件以及蜉蝣的栖息地偏好有关。相比之下，由于栖息地条件更有利，附近溪流中观察到了更高的物种丰富度和数量。记录的物种中有3种来自泥炭沼泽， 种来自溪流，它们都是克罗地亚蜉蝣动物区系的新记录。几种物种（如 、 、 ）证实了典型的中欧生命周期模式，而其他几种（如 、 ）则观察到了一些差异。因此，这些结果为泥炭沼泽栖息地中蜉蝣的生态学提供了新的有价值信息。
