The Andes-Amazon basin of Peru and Bolivia is one of the most data-poor, biologically rich, and rapidly changing areas of the world. Conservation scientists agree that this area hosts extremely high endemism, perhaps the highest in the world, yet we know little about the geographic distributions of these species and ecosystems within country boundaries. To(More)
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(More)
Understanding large-scale patterns of beta- and alpha diversity is essential for ecoregional conservation planning. Using the 110,000 km2 shallow basin of the Beni savannas of northeastern Bolivia, we examined the spatial patterns of biological diversity of four taxonomic groups (bats, palms, reptiles, and amphibians). Since the Beni savannas are shaped by(More)
Accurate extent of occurrence (EOO) estimates are essential for reliable conservation assessments. Recent studies suggest that current EOO maps often significantly overestimate range sizes of birds, particularly for narrow-ranging, threatened and ecological specialist species. Such species may therefore be at danger of being falsely overlooked by(More)
