Rotifers as indicators of lake types in Estonia

摘要: Data on the pelagic rotifer fauna in 10 Estonian lakes accumulated for 20 years, as well published data are analysed. It is possible to distinguish three main indicator groups among rotifers: (1) oligo- and mesotrophic (Ploesoma hudsoni, Keratella serrulata, Synchaeta grandis, Asplanchna herricki, Ascomorpha ovalis, Gastropus stylifer, Conochilus hippocrepsis); (2) meso-and eutrophic (Trichocerca capucina, Filinia longiseta, F. limnetica, quadrata, K. cochlearis tecta, K.c. hispida, Polyarthra euryptera, hiemalis, Trichocerca porcellus, T. pusilla); (3) (Brachionus spp., Anuraeopsis fissa, Pompholyx sulcata, P. complanata, cylindrica, Hexarthra mira).
