Abstract(s)

The understanding of the relationship between communities and the landscape mosaic, shaped by the different land uses, is important for an integrated management of the habitats. The landscape indexes might be a useful tool for landscape analysis as well as a landscape describer. The scope of this work is to check the reliability of some landscape indexes by using a multi scale approach, verifying how the nesting passeriformes birds communities are related with the landscape structure of the montado . Data was obtained from bird and vegetation census and form a spatial analysis applied on a land use map. Multivariate statistics analysis were performed and interpreted accordingly with the species ecological requirements in order to detect the more reliable scale for landscape indexes.
