Mapping Amazonian biodiversity accurately is a major challenge for integrated conservation strategies and to study its origins. However, species boundaries and their respective distribution are notoriously inaccurate in this region. Here, we generated a georeferenced database of short mtDNA sequences from Amazonian frogs, revised the species richness and the delimitation of bioregions of the Eastern Guiana Shield and estimated endemism within these bioregions.

对亚马逊河蛙进行的基于DNA的大规模调查表明，物种丰富度和特有度被大大低估了

准确地绘制亚马逊生物多样性图是综合保护战略和研究其起源的主要挑战。然而，众所周知，该地区的物种边界及其各自的分布不准确。在这里，我们生成了来自亚马逊蛙的短mtDNA序列的地理参考数据库，修改了物种丰富度和东圭亚那盾构生物区划界，并估计了这些生物区内的地方性。
