Figure 3

Example of customized analytical base map and calculation methods of three types of predictor variables. Panel A shows an example of the calculation of the values of nine variables for spatial modeling. Black open circles indicate ten sizes of concentric circle (100–1000 m in radius, at 100 m intervals) centered on a den site or a control point. In this figure, only circles of 200, 400, 600, 800, and 1000 m are shown. The pink circle indicates a 600 m concentric circle. Percentages of the dimensions of nine landscape feature categories included in the circle centered on a den site were calculated as shown in the pink call-out. Panel B shows an example of habitat determination by single point analysis. Black open circles indicate a 10 m radius circle centered on a den point or a control point. Just one habitat of a den site included in the radius is determined as shown in the pink call-out. Panel C shows an example of measurements of the values of nine variables for linear distance analysis. Black arrows indicate the shortest distances to the nine landscape feature categories from a den site or a control point. The distances to the nearest nine landscape features from a den site were measured as shown in the pink call-out.
