Postdoctoral Fellow: Molly C. Womack Proposal number: 1611752 This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2016, Research Using Biological Collections. The fellowship supports a research and training plan for the Fellow to take transformative approaches to grand challenges in biology that employ biological collections in highly innovative ways. The title of the research plan for this fellowship to Molly C. Womack is 'Selection and Constraints on Evolution of the Anuran Skeleton' The host institutions for this fellowship are the University of California-Berkeley and the Smithsonian Institution's National Museum of Natural History, and the sponsoring scientists are Dr. Erica Bree Rosenblum (UC-Berkeley) and Dr. Rayna Bell (Smithsonian). The goal of this research is to identify selection pressures and evolutionary limitations acting on the skeleton diversity of frogs (anurans) over 160 million years of evolution. The Fellow is using X-ray microtomography (micro-CT) to examine the skeletons of 200 genera, spanning all 55 families of frogs. Using this dataset, the Fellow is analyzing the co-evolution of traits and providing a comprehensive study of anuran skeleton diversity. Despite the vast diversity of forms seen in nature, particular phenotypes evolve repeatedly across both closely related and deeply divergent species (convergent evolution). Frogs show rampant convergence and provide an exceptional system for researching the constraints and selection pressures that dictate evolutionary convergence as well as the limits of morphological evolution. The Fellow is using collections at the UC-Berkeley Museum of Vertebrate Zoology and the Smithsonian National Museum of Natural History to generate a dataset to understand convergent evolution and evolutionary development. The 3D models of 200 anuran skeletons are being made freely available to other researchers and the public, allowing future studies to easily collect morphological data from museum specimens without destruction of any curated specimens. In addition to the proposed research, the Fellow is utilizing this extensive dataset to highlight species and clades of frogs that would provide ideal comparisons for future research investigating the evolution of skeletal traits. The Fellow is receiving training in micro-CT methods and comparative phylogenetic analyses. The Fellow is collaborating with both the Berkeley Natural History Museums Project and the Smithsonian's Q?rius program to create and implement lessons to communicate concepts such as adaptation and convergent evolution to broad audiences. These lessons use interactive 3D models of museum specimen skeletons that the Fellow is generating, and that are being made freely available for teachers and the general public through the Berkeley Natural History Museums Project and Q?rius websites. The Fellow is also mentoring multiple undergraduate researchers on the manipulation and quantification of 3D data as well as data for comparative phylogenetic analyses. These undergraduate researchers also have access to the broad dataset generated by the Fellow's research, for use in independent research projects.

博士后研究员：Molly C. Womack提案编号：1611752此行动为NSF博士后研究奖学金提供了2016财年生物学生物学研究奖学金，使用生物收集。奖学金支持该研究员的研究和培训计划，以采用变革性的方法来解决以高度创新的方式采用生物收集的生物学挑战。 该奖学金的研究计划的标题是“选择和限制Anuran骨架的选择”，这是该奖学金的主机机构是加利福尼亚 - 伯克利大学和史密森尼大学国家自然历史博物馆，并且赞助科学家是Erica Bree Bree Bree Rosenblum（Uc-Berkeley Belly and shithery and shithne sidgene sidgene and shithne sidgene sille national）。 这项研究的目的是确定对青蛙（Anurans）骨骼多样性的选择压力和进化限制，超过1.6亿年。 该研究员正在使用X射线显微学（Micro-CT）检查200属的骨骼，涵盖了所有55个青蛙家族。使用此数据集，该研究员正在分析性状的共同发展，并提供了对Anuran骨架多样性的全面研究。尽管自然界中看到的形式大量多样性，但特定表型在密切相关和深度不同的物种（收敛进化）中反复演变。青蛙表现出猖ramp的融合，并提供了一个杰出的系统，用于研究决定进化融合的约束和选择压力以及形态进化的局限性。该研究员正在加州大学伯克利分校的脊椎动物动物学博物馆和史密森尼国家自然历史博物馆生成一个数据集，以了解收敛进化和进化发展。其他研究人员和公众可以免费提供200个Anuran骨骼的3D模型，从而使未来的研究可以轻松地从博物馆标本中收集形态数据，而不会破坏任何策划的标本。除了拟议的研究外，该研究员还利用这个广泛的数据集强调了青蛙的物种和进化枝，这些物种将为未来的研究提供理想的比较，以研究骨骼特征的演变。该研究员正在接受Micro-CT方法和比较系统发育分析的培训。该研究员正在与伯克利自然历史博物馆项目和史密森尼的Q？rius计划合作，以创建和实施课程，以传达诸如适应和融合进化的概念。这些课程使用该研究员正在生成的互动3D模型的骨骼，并通过伯克利自然历史博物馆项目和Q？rius网站免费为教师和公众免费提供。该研究员还指导多个本科研究人员的3D数据操纵和定量，以及用于比较系统发育分析的数据。这些本科研究人员还可以访问该研究同胞生成的广泛数据集，用于独立研究项目。
