| Description | In this study we explored the taxonomic composition of Diptera larvae (excl. Simuliidae and Chironomidae) and the major abiotic parameters determining dipteran larva assemblages in the Western Carpathian spring fens. Altogether 14 sites differing in their mineral richness and substrate characteristics were chosen for the study. We used cluster-analysis and detrended correspondence analysis (DCA) to analyse patterns in sample structure. Ordination analysis revealed four groups of spring fens that supported different dipteran assemblages. Springbrooks draining the tufa-forming fens, which are characterised by coarse substrate, were dominated by madicolous and hygropetric taxa (e.g. Pericoma calcilega). Brown-moss fens with a high amount of organic matter in springbrooks were dominated by Ptychoptera lacustris, and Sphagnum-fen streamlets with a high proportion of fine sediments and with the lowest pH values were characterised by Chrysops caecutiens, Hybomitra sp. and Dasyhelea sp. |
