物种的灭绝风险受到其地理范围大小的影响，因为范围较小的物种更有可能在干扰事件后灭绝。从理论上讲，异质景观可以维持小范围的物种，因为它们促进了各自受限于不同非生物条件的类群的共存。然而，我们并不完全了解这一过程是否更多地归因于不同景观的栖息地类型（栖息地异质性）或物理海拔（地形异质性）的变化。在这里，我们比较了栖息地与地形异质性对非洲哺乳动物活动范围大小的影响。
The extinction risks of species are influenced by their geographical range sizes, as species with smaller ranges are more likely to go extinct following disturbance events. Theoretically, heterogeneous landscapes can maintain small‐ranged species, because they facilitate the coexistence of taxa that are each constrained to distinct abiotic conditions. However, we do not fully understand whether this process is more attributable to variation in habitat types (habitat heterogeneity) or physical elevations (topographic heterogeneity) across landscapes. Here, we compare the influences of habitat versus topographic heterogeneity on mammalian range sizes in Africa.
