Differences in the umbrella effects of African amphibians and mammals based on two estimators of the area of occupancy

摘要: Conservation organizations are collecting large-scale data regarding distribution and threats to vertebrate taxa. These sets will enable planners systematically identify conservation priorities; however, they cover only a tiny proportion of living organisms. Therefore, it is essential investigate what extent the areas selected for actions can provide protection other species. We analyzed umbrella effect between amphibians mammals across mainland Africa. built habitat suitability models within geographic ranges 1654 species, based on collected in framework World Union (IUCN) Global Amphibian Assessment IUCN Mammal Assessment. applied systematic reserve selection algorithms two estimators area occupancy (geographic estimated suitable areas) thus four systems. then quantified that each systems provided mammals. Reserves were comparable area, with former concentrated Afrotropical region latter more evenly dispersed. reserves left fewer gaps species coverage among than reverse, but amphibian included larger mammal's reverse. For both taxa, setting include instead resulted clustering tropics. Furthermore, efficiently protected hidden (species unsuitable portions their range inside taxon higher taxon. Overall, Africa acted as an high Focusing improved
