Sažetak
Peat bogs are unique wetland ecosystems of high conservation value all over the world. Despite that, the data on the macroinvertebrates, including mayfly communities in these habitats are still scarce. The study was conducted in the period between March and November 2015. Mayflies were sampled together with other macroinvertebrates by rectangular net of 25 × 25 cm with a mesh size of 500 µm in various lentic habitats and a stream at the peat bog edge. In total, ten mayfly species were recorded, two of which in the peat bog lentic habitats and nine in the stream. Additionally, mayflies were completely absent from shallow lentic water bodies in the peat bog. Low species richness and abundance in the peat bog were most likely related to the harsh environmental conditions and mayfly habitat preferences. Contrary to that, higher species richness and abundance were observed in the nearby stream. Three of the recorded species, Caenis luctuosa, Ephemerella karelica and Leptophlebia marginata are new records for Croatian mayfly fauna. Typical life cycle patterns were confirmed for several species (e.g. Baetis vernus, Nigrobaetis niger), while for several other (e.g. B. rhodani, Cloeon dipterum) some discrepancies were observed. Therefore, these results provide new and valuable information on ecology of mayflies in peat bog habitats.
