The small mammal community of the marshy meadows in the Ljubljansko barje area (Yugoslavia)

Spring and autumn population densities and biomasses of small mammals were estimated by the removal standard minimum method during two consecutive years (1985-1986) in the marshy mea­dows of the Ljubljansko barje (NW Yugoslavia). Ten species of insectivores and rodents were recor­ded: Neomys fodiens, Neomys anomalus, Sorex araneus, Crocidura leucodon, Clethrionomys glareo­lus, Pilymys subterraneus, Microtus arvalis, Micro/us agreslis, Apodemus sylvaticus, and Apodemus flavicollis. M. arvalis was subdominant in 1985. M. agreslis and S. araneus were euconstant species. Population densilies in spring were between 29,7 and 101,7 ind./ha, and 253/7 ind./ha in autumn. Bio­masses were between 632 and 2756 g/ha in spring and 4693 g/ha in autumn.
