During the research in floodplain of river Morava several groups of invertebrate fauna (Mollusca, Acari, Areneae, Collembola and Coleoptera) were studied. These animal groups were studied in various habitats with different soil moisture during the years 2000-2002. Standard methods of field research were used there. During the research the basic soil characters were observed (ammount of water, porosity, air content, specific weigth of soil samples) and the ammount of rainfall was measured. Two the most wet habitats involved the lower number of invertebrate species with both the lowest density and the frequency. Mildly wet flooded meadow showed the richest communities of the majority of invertebrates. This habitat included mainly semihygrophilous species with the highest abundance, frequency and the highest number of species. Vertically the highest situated habitat was inhabited mainly by species requiring mildly wet or drier soils. The abundance and number of hygrophilous species decreased with the decreasing ammount of water in the soil. Community structure of invertebrates changed within the gradient of soil moisture and each habitat showed characteristic species living there.
