This award supports an NSF Postdoctoral Research Fellowship in Biology for FY 2018, Research Using Biological Collections. The fellowship supports research and training of the fellow that will utilize biological collections in innovative ways. Explanations for the spectacular success of fish are complex and must account for many factors. To advance this field, this project investigates extinct and living species of pufferfishes, boxfishes, triggerfishes, ocean sunfishes, and allies called tetraodontiforms that include some of the most extreme body shapes in the Fish Tree of Life. These body types range from nearly square to globose, and spheroid to laterally compressed. Tetraodontiforms harbor the smallest vertebrate genomes known to date and one the best-known and well-studied fossil records among fishes. Recent evidence suggests that diversification dynamics (speciation and extinction) in this group are linked to a period known as the Paleocene Eocene Thermal Maximum (ca. 50 Ma). It is still unknown, however, how this event or other paleoclimate changes affected their body shape evolution over time.This project will synthesize a comprehensive, all species, tetraodontiforms phylogeny, by quantifying morphological evolution using 3D morphometrics and body size diversity by leveraging biological collections. It will characterize the evolution of candidate genes associated with body size change in tetraodontiforms, and use comparative methods to test how morphological evolution contributes to tetraodontiform fish diversification. Aside from scientific endeavors, these funds are also being used to contribute to community-driven scientific efforts, student training, and public outreach. Training and mentoring of undergraduate and graduate student from underrepresented minorities constitute a core goal of the activities of the project. Outreach activities include the participation in a long-term program for Chicago disadvantaged youths through the Project Exploration Sisters4Science Program, and lectures at existing programs at the University of Chicago, such as Saturday Scientist and their active Women In Science programs. This project will also broadcast knowledge on fish diversity through a variety of social platforms and at scientific meetings.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项支持2018财年NSF生物学博士后研究奖学金，使用生物收集的研究。该研究金支持研究员的研究和培训，以创新的方式利用生物收藏。鱼类惊人成功的解释是复杂的，必须考虑到许多因素。为了推进这一领域，该项目调查了河豚，箱鲀，刺鲀，海洋太阳鱼和称为tetraodontiforms的盟友的灭绝和生活物种，其中包括鱼类生命树中一些最极端的身体形状。这些体型从近方形到球状，从球状到侧扁。Tetraodontiforms拥有迄今为止已知的最小的脊椎动物基因组，也是鱼类中最知名和最好研究的化石记录之一。最近的证据表明，这一群体的多样化动态（物种形成和灭绝）与古新世始新世热最大期（约2000年）有关。50 Ma）。然而，这一事件或其他古气候变化如何影响它们的体型演变仍然是未知的。本项目将通过利用生物收集的3D形态测量学和体型多样性来量化形态演变，综合综合全面的所有物种，tetraodontiforms。它将描述与tetraodontiforms体型变化相关的候选基因的进化，并使用比较方法来测试形态进化如何有助于tetraodontiforms鱼类多样化。 除了科学努力，这些资金也被用来促进社区驱动的科学工作，学生培训和公众宣传。培训和指导来自代表性不足的少数群体的本科生和研究生是该项目活动的核心目标。外联活动包括通过项目探索姐妹4Science方案参与芝加哥弱势青年的长期方案，以及在芝加哥大学现有方案中举办讲座，如星期六科学家及其活跃的妇女参与科学方案。该项目还将通过各种社交平台和科学会议传播有关鱼类多样性的知识。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
