摘要: In mosaics of forest environment the bank vole Clethrionomys glareolus (Schreber, 1780) prefers patches with dense vegetal cover like understorey or tall herbaceous plants, ferns sedges. The size and intensity space use, rate colonization free population increases mean home range soze are highest in habitats, their parts, covered uniformly by this type vegetation. Habitats uniform characteristically support high densities, numbers sexual active individuals, survival rates individuals entering at beginning repreductive season, a emigration during second half season low immigration. Vole populations habitats poor clumped characterized immigration to turnover individuals. It has been suggested that distribution mosaic depends upon abundance structural elements habitat thay may serve as defensive structures against predators.
