Descrição: Decades of research suggest that species richness depends on spatial characteristics of habitat patches, especially their size and isolation. In contrast, the habitat amount hypothesis predicts that (1) species richness in plots of fixed size (species density) is more strongly and positively related to the amount of habitat around the plot than to patch size or isolation; (2) habitat amount better predicts species density than patch size and isolation combined, (3) there is no effect of habitat fragmentation per se on species density and (4) patch size and isolation effects do not become stronger with declining habitat amount. Data on eight taxonomic groups from 35 studies around the world support these predictions. Conserving species density requires minimising habitat loss, irrespective of the configuration of the patches in which that habitat is contained. Analysis of a global set of 35 studies suggests that habitat amount, rather than patch area, isolation or fragmentation per se, determined species richness in sample plots at scales ranging from 13 to 11 000 ha. Minimising species losses requires protecting and restoring as much habitat as possible, irrespective of the configuration of that habitat.
