摘要: We present a global conservation analysis for an entire “flagship” taxon, land mammals. A combination of rarity, anthropogenic impacts, and political endemism has put about quarter terrestrial mammal species, larger fraction their populations, at risk extinction. new database complementarity selecting priority areas shows that ∼11% Earth's surface should be managed to preserve least 10% geographic ranges. Different approaches, from protection (or establishment) reserves countryside biogeographic enhancement human-dominated landscapes, will required approach this minimal goal.
