Aim: This study provides data about the freshwater gastropods of the Danube wetland area Dubova
ki
Rit (1082 1085 river km), aiming to contribute to the knowledge of this taxa group, its assemblage
composition and species abundances.
Materials and Methods: The study of freshwater gastropods was performed in the Dubova
ki Rit at the
left bank of the Danube River. Sampling was performed in 2010, 201l and 2014, four times per year
using benthological hand net and a Van Veen type of grab. The yotal number of taxa, species
composition and abundance were calculated using the ASTERICS software package.
Results: During the research a total of 12 species were recorded, all belonging to the Planorbidae family.
The most abundant species were Segmentina nitida (M., 1774)- 16 specimens, Physella acuta (D., 1805)
- 12 specimens, Hippeutis complanatus (, 1758) 11 specimens, Ferrissia fragilis (T., 1863) - 10
specimens and Anisus vortex (L., 1758) - 9 specimens. Other species were represented with less than 5
specimens (Gyraulus albus, G. erista, Bathyomphalus contortus, Planorbarius cormeus, Planorbis
planorbis, Acroloxus lacustris and Lymnaea stagnalis). Two species (P. acuta and F. fragilis) are nonnative
to the Danube River. At the site inavasive macrophyte Paspalum paspaloides (Michx.) forms
underwater meadows.
Conclusion: The majority of the observed species are phytophilowus taxa. Seasonal differences in
macrophyte density and community composition additionally contribute to the habitat complexity. On this
specific the habitat dominated by invasive P. paspaloides two alien species of snails were recorded.
