Habitat identity influences species-area relationships in heterogeneous habitats

Loss of habitat is commonly identified as a reduction in area (or patch size) and its effects are often investigated using species-area relationships to evaluate loss of biodiversity. In many habitats, however, area alone is not sufficient to explain the decline of populations because natural habita...
