Abstract

The sampling sites included montane and lowland riparian plant communities of early or advanced successional stages as well as forests of hilly region, which often extend.to riverbanks. The plant communities differ from each other by the composition of their snail assemblages, as it is proved by the results of cluster and principal component analyses. It was concluded, that ubiquitous and continental species {Bradybaena, Deroceras rodnae, Succinea putris, Helix lutescens) dominate among snails transported by the Somej/Szanios over long distances. Species of narrow ecological tolerance range can be found in the riparian vegetation of the Somej/Szamos Valley and also of minor watercourses arriving from neighbouring hills and mountains. The fauna dispersal from the spring region is hampered by water reservoirs, shrinkage of forest habitats to single row of trees along the river and the lack of riparian gallery forests in the flood area. The biotopes are subjected to the strongest human impact resulted from the forest management, or logging the flood plain into agricultural fields. The garbage disposal in/or near the riparian vegetation also cause major disturbances for the snail assemblages.
