Patterns of Speciation and Biogeography of Anuran Amphibians in the Central Andes

通过分支学方法分析秘鲁安第斯高原蛙类种群的形态和遗传差异，将有可能确定五个蛙类谱系的进化关系。一旦完成，物种形成和生物地理的重复模式将与气候和地质变化历史模式的现有数据进行比较。这些结果将解释这种变化是如何影响青蛙的物种形成和分布的，并将为与其他生物群进行比较提供基础。

By analyzing the morphological and genetic differences among populations of species of frogs in the high Andes in Peru by cladistic methods, it will be possible to determine the evolutionary relationships of five lineages of frogs. Once this has been accomplished, repetitive patterns of species formation and biogeography will be compared with existing data on historic patterns of climatic and geologic changes. The results will provide an interpretation of how such changes affected the speciation and distributions of the frogs and will provide a basis for comparison with other groups of organisms.
