Outcomes of the malaco-transsect collected in the Déda and Zám Pass, and in Maroslekence in the Transylvanian Basin (Romania) - Klára Váncsa - Tamás Domokos Resume In the summer of 1999 a research programme embracing the total length of the River Maros was launched, in which surveying the terranean malaco-fauna of the river valley started. During the collecting tour we took samples in total of 14 places in the Maros Valley. Out of them in three places we performed transsect sample collection. Collection places of the three transsect are located in the well-distinguishable lands crossed by the River Maros: the first is in the Maroshéviz-Déda Pass, at the Galónya Rock; the second is in the Transylvanian Basin where the river is flowing already in a flat area, while the third is in the Zám Pass separating the South Carpaths from the West Szigethegység. In the survey of the three transsect we concluded that the park forests extending in the flood-basin are the land elements richest in species. It is because two fluctuational zones meet here: the first is coming from the earth, the other is from the river. The bank's park forests are important starting points of the spread of species, while providing settlement opportunities for coming species. On account of the anthropogene intervention diversity of the malaco-fauna is diminishing. The malaco-fauna plastically indicates the micro-climate of a region: in spite of the fact that migration of species seeks to mix the diversity between certain biotopes. Species with great ecological tolerance can be found in most of the lands and their homogenising impact is considerable.
