摘要

We analysed the variation ofsmall mammal species composition in the TawnyOwl Strix aluco L. diet in forest habitats of Cen-tral European Lowland. We used published andunpublished materials from forest-dominatedlandscapes in Lithuania (n = 7 locations), Po-land (n = 8) and East Germany (n=1); marginallocalities were ca. 870 km from each other. Werecorded that in Central European Lowland theproportion of Arvicolidae in the Tawny Owl dietsignificantly increased, while that of Muridae de-creased toward north-east. The proportion of lesscommon rodent species (including Gliridae andSicita betulina Pallas) in the diet also increasedsignificantly toward NE. We did not record anytrend of small mammals diversity along the ana-lysed transect. We suggest that the change of Ar-vicolidae to Muridae ratio toward north-east canbe caused by the replacement of mice with borealvole species in small mammal community. Smallmammal diversity in Central Europe is subject ofdiscussion.
