Kisemlősök populációs és közösségi vizsgálata két ártéri erdőtípusban

Abstract

Two 1-hectare forest stands were chosen as sampling sites in the monitoring area of river Drava: one was a softwood willow-poplar (Salici-Populetum) gallery forest directly along the river in the neighbourhood of Vízvár, whereas the other was a lowland alder gallery forest (Paridi quadrifoliae-Alnetum) within the Lankóci forest. Quadrate sampling method and line transect (the latter in Vízvár in 2001) were applied. The number of the box-type live traps was 121 in the grid, and a maximum of 120 in the transect. Trapping was done using the capture-mark-recapture (CMR) method. So far 3 shrew and 3 rodent species have been indicated in the Vízvár sample area, and 8 species comprising 5 rodents and 3 shrews in the Lankóci forest stand. The dominant species in the willow-poplar gallery forest has been Apodemus agrárius (Pallas, 1771), whereas the abundant characteristic species of the alder forest has been Clethrionomys glareolus (Schreber, 1780).
