If we look at the number of marked individuals in each species, it appears that M. arvalis was the dominant species of this abandoned area, besides A. agrárius (24.4% relative frequency), A. sylvaticus (15.2% rel. fr.) and A. flavicollis (16.1% rel. fr.). In 1998 the difference between the genera Apodemus and Microtus was even higher (23 %); in this trapping period representatives of the genus Apodemus were captured at an even higher rate (Fig. 3). Fig. 2. Occurrence percentage in habitat A in 1997 Fig. 3. Occurrence percentage in habitat A in 1998 Among them A. agrárius had the highest relative frequency (42.09%), whereas A. flavicollis gave 9.76% and A. sylvaticus gave 6.57% of the total number of individuals. Thus, in 1998 A. agrárius was the dominant species, as opposed to M. arvalis. From a faunistical perspective it is important to note that species belonging to the genus Crocidura (Crocidura suaveolens [Pallas 1811], Crocidura leucodon [Hermann 1780]) were present in much higher numbers in the second study year. In site B we trapped 4 representative species of the order Insectivora and 5 species belonging to Rodentia. This totals to 428 marked individuals. As the areas become more and more marshy, both Neomys species (Neomys fodiens [Pennant 1771], Neomys anomalus Cabrera 1907) appear in higher densities (Tables 3-4).
