About the Ranking of Isolated Habitats with Different Shapes: An Interior-to-Edge Ratio Study

Abstract

Isolated habitats can be compared and ranked by comparing their interior-to-edge ratio (I/E). We would like to show here that results based on ranking by I/E ratio sometimes contradict Diamond's rule, which ranks the most rounded habitat (i.e. most compact) as the best one. The reason for this contradiction is the frequently overlooked size dependence of the I/E. Being the interior-to-edge ratio size dependent, from a given set of habitats of different sizes, compact shaped (rounded) habitats might have worse I/E ratios than elongated or irregular ones.
