LANDSCAPE ECOLOGY A Top-Down Approach - Chapter 7 pps

... Figure 7. 1 shows a hypothetical landscape overlaid with 100 hexagonal cells. Each grid cell is assigned a habitat value for a particular organism. At first appearance, the landscape appears to have ... LLC Average habitat quality over the region for S j can be calculated by assign- ing values to each habitat. Let optimal habitat have a value of 8, suboptimal habitat a value...
