Sažetak
Rotifer and zooplankton assemblages in three reservoirs differing in their size and trophic state, i.e. eu- trophic Konče 1 and Konče 3 and oligotrophic Špilje, were examined. Considerable differences were recorded among reservoirs in their environmental parameters, zooplankton composition, species diver - sity and abundance. High abundance and dominance of rotifers as well as higher species diversity in the zooplankton were observed in more productive, eutrophic reservoirs Konče 1 and Konče 3 compared to the oligotrophic Špilje Reservoir characterised by prevalence of planktonic crustaceans. Dominant rotifer species in eutrophic reservoirs were Brachionus falcatus, Brachionus angularis and Hexarthra mira ; Špilje Reservoir was dominanted by Kellicottia longispina , a species characteristic for less productive waters. The significant correlation between trophic state index and rotifer abundance indicates that rotifers are useful biological indicators of water ecological status.
