Table 2 Landscape models and corresponding resistance values assigned to each cover type or range in CIRCUITSCAPE analyses
From: Influence of landscape features on the microgeographic genetic structure of a resident songbird
Model | Resistance values assigned to cover types/ranges | Hypothesis |
|---|---|---|
Null | Uniform landscape (all cells given a value of 1) | Isolation by distance |
Land cover | Mixed forest=1 | Isolation by resistance |
| Â | Broadleaf forest=2 | Â |
| Â | Coniferous forest=5 | Â |
| Â | Shrubland=10 | Â |
| Â | Grassland/wetland/bryoids=100 | Â |
| Â | Unsuitable habitat (incl. agricultural land)=1000 | Â |
Elevation | 0–800 m=1 | Isolation by resistance |
|  | 801–1000 m=5 |  |
|  | 1001–1500 m=10 |  |
|  | 1501–2300 m=100 |  |
|  | 2301–3454 m=1000 |  |
Land elevation | Combined land cover and elevation resistance maps using ‘raster calculator’ | Isolation by resistance |
