The aim of this study is to present the distribution of aquatic molluscs
along a 2600 km long stretch of the Danube River based on information
obtained during the Second Joint Danube Survey (JDS2) in 2007. The
collected data are used to validate the abiotic typology of the Danube
River and to determine the extent of variations in mollusc richness and
composition that can be explained by the basic habitat characteristics
of the sites. The examination of the distribution of mollusc fauna
reveals differences between the three main sectors of the river, the
Upper, Middle and Lower Danube. The Iron Gate Section was identified as
the boundary between the Middle and Lower, Danube. A total of 42 aquatic
mollusc species-group taxa of 14 families are detected within the study
area. The Middle and Upper sectors are characterised by higher species
richness and diversity as compared to the Lower Danube.
