Escolha de áreas prioritárias de conservação de anfíbios anuros do cerrado através de um modelo de populações centrais-periféricas

Abstract

Habitat loss causes great threats to biological diversity, and one of the alternatives to protect biodiversity is reserve planning using optimization tools to establish conservation priority areas. In this study, a simulated annealing algorithm was used to analyze the influence of species distribution margins on selection of areas in Cerrado, for 131 anurans species. For this purpose, we used two databases: one containing the original species distribution, and another with the periphery of distributions excluded. Networks selected using the original distributions contained 17 cells, whereas networks found with the reduced distributions were larger, with 22 cells. The irreplaceable cells were the same in all networks, and new regions of replaceable cells in the margins of the biome arise when distributions without peripheral areas were considered.
