A long-term study of mayfly emergence patterns in the Dinaric Karst freshwater habitats
Mayfly emergence patterns were studied over a ten-year period in two types of karst freshwater habitats: a spring and two tufa barriers, using pyramid-type emergence traps. A total of nine mayfly species were recorded. The highest proportion of collected individuals belonged to the genus Baetis Leach, 1815 which was recorded at all three study sites, but we were unable to distinguish between two included species (B. rhodani (Pictet, 1843) and B. cf. nubecularis (Eaton, 1989)). Other numerous recorded species were Paraleptophlebia submarginata (Stephens, 1835), Ephemera danica Müller, 1764 and Rhithrogena braaschi Jacob, 1974. Tufa barriers had higher species richness but lower population densities compared to the spring. NMDS analysis separated spring from tufa barriers. In the studied spring, emergence mainly occurred between March and November, and the main trigger for emergence was photoperiod. In tufa barriers, emergence mainly occurred between April and July and was related to the elevated water temperature. Generally, a higher abundance of emerging individuals was recorded during the years with higher water discharge. Emergence patterns of some species were in accordance with their typical Central European emergence patterns (e.g. E. danica) while some other showed certain discrepancies (e.g. Rh. braaschi).
