Fig. 3From: Understory vegetation in planted pine forests governs bird community composition and diversity in the eastern Mediterranean regionNMDS ordination of the bird species in relation to the habitat structure parameters in three types of forest habitats: No understory forest, NF (1), Dense forest, DF (2) and Open forest, OF (3). Significant separation between the No understory forest habitat and the other two habitats are marked in polygons (NF in red, DF in blue, OF in gray). Bird species are marked in light grey numbers (for full bird names see Table 5 in Appendix); plots are marked by circles and arrows represent vectors of the significant factors that contributed to the ordination (p < 0.05): See Table 6 in Appendix for more information on the statistical results of the MNDS ordinationBack to article page
