Temporary periodical pools of the lower reaches of the Dyje (Thaya) River

Abstract

The qualitative composition and biology of aquatic invertebrates of the periodical pools of the lower Podyjí region is presented in the study. In the floodplains of south Moravia are many of vernal periodical pools with typical fauna e. g. Lepidurus apus, Eubranchipus grubii, Cyzicus tetracerus, Stygobromius ambulans, Hemidiaptomus amblyodon, Mixodiaptomus kupelwieseri, Diaptomus castor. Periodical vernal poools emerge after snow thawing, rains or floods. The summer periodical pools are at lower reaches of the Dyje River very rare. In this sort of pools live e. g. Triops cancriformis, Branchipus schaefferi, Leptestheria dahalacensis, larvae of mosquito Aedes vexans, Anopheles maculipennis, Culiseta annulata. The presented data may be avalaible for comparative study in the future with respect to expected global climate changes.
