项目摘要

An unresolved question in evolutionary biology is the extent to which past adaptations influence adaptations of species to a new environment. For example, does past adaptation to an ancestral microhabitat (e.g., trees) constrain adaptation to a novel microhabitat type (e.g., water)? Or does adaptation to a new microhabitat completely erase any traces of previous evolutionary history? This question will be addressed in frogs of the world through measuring performance (e.g., jumping, swimming), body form (e.g., size, shape), and habitat use, and then estimating change during the evolutionary history of frogs via an understanding of evolutionary relationships among species. Data have been collected within China and Colombia, and this grant will extend the sampling to Australia, as well as allowing further work at museums in the U.S. This research will lead to an understanding of the influence of historical influences (e.g., previous habitat use and adaptations to it) on subsequent evolutionary change, something that has not previously been well understood. Furthermore, this project will result in the training of undergraduate students in research in evolutionary biology, as well as develop international collaboration with scientists from Australia and develop cross-cultural understanding through outreach presentations, both in the U.S. and Australia.

进化生物学中未解决的问题是过去适应影响物种对新环境的适应程度的程度。例如，过去适应祖先微栖息地（例如，树）是否会限制对新型微栖息地类型（例如水）的适应？还是适应新的微栖息地完全消除了以前进化史的任何痕迹？这个问题将通过衡量表现（例如跳跃，游泳），身体形态（例如，大小，形状）和栖息地的使用，在世界青蛙中解决，然后通过理解青蛙的进化历史上的变化，通过了解物种之间的进化关系。数据已在中国和哥伦比亚境内收集，该赠款将把抽样扩展到澳大利亚，并允许在美国的博物馆进行进一步的工作，这项研究将导致人们了解历史影响的影响（例如，以前的栖息地使用和对其的适应）对随后的进化变化的影响，这是以前尚未得到充分理解的。此外，该项目将导致对进化生物学研究的本科生进行培训，并与来自澳大利亚的科学家发展国际合作，并通过美国和澳大利亚的外展演讲发展跨文化的理解。
