| FIG. F1. Map of the 21 experimental patches in the three study forests around the city of Bern. Yellow patches: low-quality patches (patches 1, 5, 8, 11, 17, and 20); red patches: high-quality patches (patches 3, 6, 9, 13, 15, and 19); orange patches: medium-quality patches (patches 2, 4, 7, 10, 12, 14, 16, 18, and 21). See text for the description of the experimental manipulation of local breeding habitat quality. Mean patch area did not differ between patch treatments (mean area ± 1 SE in ha: high quality patches: 19.3 ± 1.1, medium quality patches: 19.8 ± 1.1, low quality patches: 20.0 ± 1.1, F2,15 = 0.24, P = 0.791. Spatial scale is identical for the three forests and is indicated). |
