Měkky i v nivě Mile ovského potoka Molluscs of the Mile ovsky Potok floodplain (Northwest Bohemia, Czech Republic)

This paper presents a research of mollusc assemblages in the Mile ovsky Potok floodplain (Northwest Bohemia, Czech Republic). Altogether, 72 mollusc species (70 species of Gastropoda, 2 species of Bivalvia) have been recorded at the selected sites during previous and recent researches in 1947–2010 representing 29% of the total Czech malacofauna. Widespread forest species dominate there (40% of all recorded species) with some less common woodland species such as Platyla polita, Oxychilus glaber, Macrogastra ventricosa, Sphyradium doliolum, and Perforatella bidentata. The rest of malacocoenoses is formed by mesophile species (22%), hydrophilous species (6%), species of wetlands (8%), freshwater habitats (8%) and species of open habitats (10%). Vertigo angustior, a rare wetland species protected by the NATURA system, and Helicella itala, endangered species of open habitats, were also found. The malacofauna of the Mile ovsky Potok stream can be used as a model of mollusc assemblages of natural floodplain environment in warm areas of Central Europe.
