Spatial patterns in the diversity of mammal species: a test of the geographic-area hypothesis in South America
Lugar: Quebec; Año: 1999 vol. 6 p. 338 - 354
The geographic distribution of 577 South American mammalian species are analysed (1) to depict the latitudinal patterns of variation in mammal species richness, and (ii) to test the geographic area hypothesis in the southern hemisphere at two scales of analysis. This hypothesis predicts that variation in the geographic area of biomes (rather than their particular environmental conditions) is the best predictor of mammal species richness.
