Sažetak
The assessment of biodiversity using all taxa in the given area is usually a time- consuming and expensive process since it requires taxonomic expertise for each group of aquatic biota. Therefore, the selection of surrogates to reliably represent freshwater biodiversity is an important topic in many recent studies. However, according to the available literature, a very few cross-taxon correlations can be considered as high enough to be used as a potential surrogate. In this study, we tested the utility of Diptera taxa to assess the freshwater biodiversity in lotic systems of central Balkan Peninsula. The total number of species, abundance, and diversity indices (Shannon-Wiener diversity index – H', Simpson index – 1-D) have been calculated for four taxa groups: Diptera, Ephemeroptera-Plecoptera- Trichoptera (EPT) group, macroinvertebrates without Diptera and fish. Spearman rank- correlation coefficients revealed that diversity of Diptera and other macroinvertebrates are correlated along the longitudinal gradient of the river basin, when the diversity was presented by 1-D (r=0.391, P<0.05). In addition, Diptera diversity was also correlated with EPT group (H', r=0.391, P<0.05). Such low level of correlation indicates a different diversity patterns among the investigated taxa groups. The obtained diversity information from different taxa groups is rather complementary, what diminishes the reliability of a surrogate approach in the biodiversity management.
