Horváth Gy. – Lanszki J. 2000: Két erdei habitat kisemlős együttesének összehasonlító szünbiológiai vizsgálata

374 Comparative ecological study of the small mammal assemblage of two forest habitats GYŐZŐ HORVÁTH - JÓZSEF LANSZKI Within the framework of two separate research programmes, live-trapping small mammal investigations were performed simultaneously in 1998 in Baranya county and Somogy county, respectively. Both samplings were done in forest habitats of similar vegetation being buffer sections of forest reserves, using the quadrate method. A total of 9 species constituted the studied small mammal assemblage in the Baranya forest, while 5 species were found in the Somogy area. The community in the forest in Baranya was more diverse in the spring and summer than the Somogy one. However, there was no such difference statistically in the autumn. This was caused by the growing densities of the dominant populations, and the disappearance of the uncommon species from the Baranya community. Both areas had 4 charactereistic rodent species, but their capture success differed between the two habitats. The dominant species in the Baranya forest was A. agrárius as opposed to A sylvaticus, whereas a reversed situation was true for the Somogy forest. Capture data were similar in the two areas in the case of A. flavicollis and C.glareolus, but the temporal changes of population size in the two plots were significantly similar only in С glareolus.
