Résumé :

Fragmentation processes can produce isolated patches from an originally continuous habitat. The shapes of the resulting patches are usually highly irregular. Due to this irregularity, their ability to endure external disturbances is different, which is an expression of their ecological quality. Traditionally, patch area and interior-to-edge ratios are used to characterize the quality of habitats but the latter one is not applicable under varying external disturbances. In this paper, we show that the internal Minkowski-Bouligand dimension (and the corresponding form-factor) can be used as a simple interior-to-edge function applicable on a variable edge width. © World Scientific Publishing Company.
