Abstract: Trappings were carried out in a forest (Querco robori-Carpinetum) habitat on the Dráva Lowlands in two periods, using the capture-mark-recapture method. The sampling grid in the 1 ha study area contained 9 by 9 trap stations for 15 months in 1995-1996, and 11 by 11 stations for 10 months in 1997. A total of 10910 trap nights were recorded in the two periods, during which 71 wood mice (Apodemus sylvaticus), 448 yellow-necked wood mice (Apodemus flavicollis), 568 striped field mice (Apodemus agrarius) and 382 bank voles (Clethrionomys glareolus) were marked. Changes in the numbers of rodent populations were characterized using MNA="minimum number alive" and abundance values obtained by the Jolly-Seber estimator. The latter yielded higher values than MNA in the four-trap-night periods and lower values than MNA in the five-trap-night sessions. For the ratio of morning mean number of captures vs recaptures by species, significantly better results were obtained in the five-night periods.
