Sažetak
Rotifer structure may serve as predictor of environmental conditions, including long-scale distance between shallow water bodies. As functional traits were not a sensitive tool to assess latitudinal variation in the northern-southern temperate European regions during spring and autumn seasons, we assumed that a taxonomic approach, referring to certain dominating species, will be a better method. An analysis of abiotic features showed a high similarity concerning water bodies in Poland and Croatia in the spring, while a clear latitudinal segregation was obtained for the autumn season. This is due to the variation of trophic conditions, with a much higher trophic state, reflected in the increases in chlorophyll a concentration and phosphates, in the case of Polish ponds in the autumn period. 17 rotifer taxa dominated, with only 7 dominating in both countries (Bdelloidea, Brachionus angularis, Filinia longiseta, Keratella cochlearis, Keratella quadrata, Polyarthra ssp., Synchaeta pectinata), however, only K. cochlearis and Polyarthra ssp., dominated in each country in the spring and autumn. There was a group of species that dominated exclusively in Croatia (Colurella uncinata, Gastropus stylifer, Lepadella patella, Trichocerca porcellus) or only in Poland (B. quadridentatus, Cephalodella catellina, Eosphora ehrenbergi, K. cochlearis tecta, Notholca acuminate, N. squamula, Synchaeta lakowitziana). K. cochlearis had the highest frequency, dominating in over 60% of samples in Croatia. A distinctiveness between the two European regions, northern and southern, with temperate climates, was obtained at the level of rotifer taxa. Thus we recommend a taxonomic approach for latitudinal studies in a seasonal aspect.
