9521691 Trueb This research involves resolution of relationships of fossil and Recent frogs in several basal lineages. In addition, there are several ancient frog fossils that have been discovered recently and that are undescribed. It is probable that these fossils will provide insights on the broader problem of basal frog relationships and biogeographic history. Recent attempts to resolve frog systematics using living taxa have been unsatisfactory and inclusion of data from the fossil record has been thwarted by poor descriptions and lack of coordinated collaborative efforts between neontologists and paleontologists. This project will address this problem and involve the collaborative research efforts of the PI, a South American collaborator and three students. %%% The significance of the research on basal frog lineages is that it will provide the framework necessary for unraveling relationships among later diverging frogs and allow a more comprehensive understanding of frog taxonomy, relationships and biogeography. ***

9521691 Trueb这项研究涉及解决化石和最近的青蛙在几个基础谱系的关系。此外，还有几个最近发现的古代青蛙化石，没有描述。这些化石很可能会为更广泛的基蛙关系和地理学历史问题提供见解。最近试图解决青蛙系统学使用活类群一直不令人满意，列入化石记录的数据已被挫败穷人的描述和缺乏协调的合作努力之间的新生物学家和古生物学家。这个项目将解决这个问题，并涉及PI，南美合作者和三名学生的合作研究工作。对基底蛙谱系的研究的意义在于，它将为解开后来分化的蛙之间的关系提供必要的框架，并使人们能够更全面地了解蛙的分类、关系和地理学。***
