Váncsa Klára: Malacofanistic investigation of the flood plain and the inundation area of the Maros River in the surroundings of the Bezdin Monastery

Váncsa Klára another. In 2004, Tamás Domokos collected malacological material in the area again, and in this way, I obtained further data after four years. Therefore, I have thought that I collect the data of several years and with respect to that and examine the malacofauna of the area. I completed my data with the data of Bába and Kondorossy (1995) relating to the area. In 2000, I carried out the collection with quadrate method (ten quadrates per biotope). However, the sampling in 2004 was done by 'thinning out' and 'mass collection' methods, on account of which I could not make the coenological comparison between the collection of 2000 and the one of 2004. In 2000 only land species, while in 2004 also aquatic species were collected. Altogether (during the collections of 1995, 2000 and 2004) 41 species were found, from which there are 30 land species and 11 aquatic ones. Amongst them many rare and worth for protection species can be found. These data series shall be deemed as complementing each other, and with this way of looking a roughly total picture forms about the malacofauna of the Nagyporond as well Bezdin area.
