摘要

两栖动物是目前世界范围内最受威胁的脊椎动物类群。在这种情况下，为两栖动物保护提供工具的研究对于减少对这一群体的威胁具有战略意义。由于缺乏对无尾虫幼虫阶段的详细描述和形态变化，以及鉴定工具的缺乏，增加了非专业人员鉴定无尾虫幼虫阶段的难度。在这里，我们提出了49种无尾猿蝌蚪的形态特征发生在塞拉多生物群系和过渡地区。此外，我们将我们的描述与现有的蝌蚪描述进行了比较，并对我们样本中发现的形态变化提供了评论。最后，我们利用无尾蝇幼虫阶段制作了一个分类钥匙，作为物种鉴定的工具。

Morphological characterization and taxonomic key for tadpoles of Brazilian Cerrado

Abstract Currently, amphibians are recognized as the most threatened vertebrate group worldwide. In this context, studies that offer tools for amphibian conservation are strategic to reduce the threats to this group. The absence of detailed descriptions and morphological variation of the anuran larval stage and the lack of identification tools increase the difficulty of anuran larval stage identification by non-specialists. Here we present the morphological characterization of tadpoles of 49 anuran species that occur in the Cerrado biome and transitional areas. Also, we compared our characterization with available descriptions of the tadpole and provided comments about the morphological variation found in our samples. Finally, we produced a taxonomic key as a tool for species identification using the anuran larval stage.
