Evaluating Multispecies Landscape Connectivity in a Threatened

Because so many species are threatened by fragmentation, habitat corridors may more effectively protect regional biodiversity if they are developed to support the movement of multiple species simultaneously, rather than movement of one single species (Beier et al. 2008). However, it remains unclear ...
