Abstract

The borderland between the Czech Republic and Slovakia is a suitable model area for studying aquatic macroinvertebrate of spring fens. Altogether, 11 and 15 sites were sampled in 2006 and 2010, respectively. In total, 134,203 individuals of 293 taxa were found. The most diverse group of macroinvertebrates was Diptera (161 taxa). Based on species composition, we distinguished four types of sites varying in mineral richness and substratum characteristics. There were differences in both species richness and abundance among these types of sites, but the compositions of macroinvertebrate assemblages were rather similar. Non-insect fauna was dominant in all groups of sites. Using redundancy analysis (RDA) with Monte Carlo permutation test, the water conductivity, depth, content of NO3-, water temperature and proportion of sand were most significant factors controlling variation of macroinvertebrate assemblages of the Western Carpathian fen streamlets.
