landscape mosaic (pooled across patch types) can have the same ecological applicability, but more often serves as a general index of spatial heterogeneity of the entire landscape mosaic. A landscape with a greater number or density of patches has a...

to as the compositional and structural components of diversity, respectively. Some indices (e.g., Shannon's diversity index) are more sensitive to richness than evenness. Thus, rare patch types have a disproportionately large influence on the magnitude...

and landscape levels. Most of these shape metrics are based on perimeter-area relationships. Perhaps the simplest shape index is a straightforward Perimeter-area ratio (PARA). A problem with this metric as a shape index is that it varies with the size...

several indices based on edge contrast at the patch, class, and landscape levels. At the patch level, the Edge contrast index (ECON) measures the degree of contrast between a patch and its immediate neighborhood. Each segment of the patch perimeter is...

Background.—The Kernel Contrast-weighted Edge Density Index is a measure of local neighborhood contrast-weighted edge density, in which each surface of the neighboring cells of the focal cell that represents an edge is doubly weighted by the...
