摘要: The aim of this study was to assess the impact isolation on forest bird communities in agricultural landscapes Netherlands. We studied avifauna 235 small (0.1–39 ha) woodlots composed mature deciduous trees 1984–1985. These were selected eastern and central/southern part country within 22 regions showing great differences landscape structure,i.e., degree isolation. Multiple regression analysis indicated that woodlot size best single predictor species number probability occurrence most species. It turned out variables, area wood, woods, interpatch distance, proximity density connecting elements, explained but significant parts residual variances number. No significantly affected by elements. Biogeographical between two groups emphasized. Evidence four woodland suggested regional abundance isolates.
