Anotácia | Chironomids collected as pupal exuviae were used to biotypological study of the river Hron, one of the biggest rivers in the West Carpathians. A total of 111 chironomid taxa were recorded at 13 sites in March, May and July 2003. Two-way indicator species analysis (TWINSPAN) was used to classify sampling sites into five groups defined by chironomid species composition. Detrended canonical correspondence analysis (DCCA) showed slope, temperature and human influence to be the variables best correlated to the chironomid data. Even the typology of the river was made in sense of the zonation concept, actual changes in chironomid assemblages along the longitudinal gradient were rather gradual than zonal. Compared with data from 1980s when zonation pattern was largely influenced by pollution stress, the present data provided the better interpretable longitudinal scheme of the river.
