Priority areas for amphibian conservation in a neotropical megadiverse country: the need for alternative, non place based, conservation
Amphibians constitute one of the most threatened species group worldwide. Because they are affected by various threats such as habitat destruction, chytrid fungus, climate change, invasive species and human use, different approaches are needed for their conservation.

Zusammenfassung: | Amphibians constitute one of the most threatened species group worldwide. Because they are affected by various threats such as habitat destruction, chytrid fungus, climate change, invasive species and human use, different approaches are needed for their conservation. In this paper we examine patterns of alpha diversity, endemism and threatened species distributions of amphibians in Bolivia. We modeled distribution data using ecological niche modeling implemented with MaxEnt (Maximum Entropy Modeling). In contrast with previous studies, we validated each individual map with specialists. Important areas for amphibian conservation were defined by overlapping species richness, endemism richness and concentration of threatened species, and then excluding all unsuitable habitats. Our goal was to identify high-priority sites for the conservation of amphibians in Bolivia. We discuss a place-based strategy (identification of priority areas) and the need for further non place-based strategies. We highlight the importance of strengthening two existing protected areas that together host up to 40% of Bolivia’s threatened amphibian species, and we propose alternative strategies such as ex situ conservation for those species not covered by the priority areas. Bolivia’s General Directorate for Biodiversity and Protected Areas (in Spanish, Dirección General de Biodiversidad y Áreas Protegidas (DGBAP)) and Bolivian experts are jointly using the here presented results to define a national strategy of amphibian conservation for safeguarding this important element of Bolivia’s biodiversity. |
