This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2019, Research Using Biological Collections. The fellowship supports research and training of the fellow that will utilize biological collections in innovative ways. The fellow's research explores how animal anatomy (form), movement (function), and environment (ecology) change together over the course of evolution. Although each of these pieces is important individually, learning how they change in connection with one another sheds light on what sparks the rapid appearance of new species, periods called adaptive radiations. The fellow's research uses bats as a model system to explore how these changes are connected. Bats comprise 20% of all living mammals and live on every continent except Antarctica. Part of what allows bats to colonize such varied places is that they evolved diverse roosting habits. The fellow hypothesizes that bats' ability to develop new roosting habits (ecology) is linked to changes in the wing skeleton (form) and landing maneuvers (function), and that these factors worked together to drive the evolution of the many bat species observed today. This work integrates form, function, and ecology, and sets the stage for future work that reveals how the many facets of animal biology work together to drive diversification across the 'tree of life'. Alongside this scientific research, the fellow will adapt museum exhibits and research into science learning supplements for incarcerated students who are working toward their high school equivalency degree, and will serve as a mentor for undergraduate research experiences at the American Museum of Natural History (AMNH).The fellow's research addresses three aims to assess links among roosting ecology, wing morphology, and landing mechanics. First, the fellow will use micro computed tomography (micro-CT) scans to compare patterns of wing inertia, which generates the forces that reorient bats' bodies during landing, across species. The second aim assesses interspecific differences in hindlimb skeletal geometry associated with the loading regimes imposed by landing impact forces. Finally, these data will be examined alongside landing maneuvers using phylogenetic comparative methods to determine whether there are clade-based links among ecological opportunity (roosting habits), landing biomechanics, morphology, and diversification rates. Through this research, the fellow will receive training in comparative morphology and phylogenetic methods through the use of museum collections at the AMNH. The fellow will work to broaden participation in science by developing STEM learning supplements for incarcerated students, mentoring undergraduate researchers, and by making research products publicly availableThis 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.

这项行动资助了2019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。研究员的研究探索了动物解剖学（形式），运动（功能）和环境（生态）如何在进化过程中共同变化。尽管这些片段中的每一个都很重要，但了解它们如何相互联系变化，有助于了解是什么激发了新物种的快速出现，这一时期被称为适应性辐射。这位研究员的研究使用蝙蝠作为模型系统来探索这些变化是如何联系在一起的。蝙蝠占所有现存哺乳动物的20%，生活在除南极洲以外的各大洲。让蝙蝠能够在如此不同的地方定居的部分原因是它们进化出了不同的栖息习惯。这位研究员假设，蝙蝠发展新的栖息习惯（生态学）的能力与翅膀骨架（形式）和着陆机动（功能）的变化有关，这些因素共同推动了今天观察到的许多蝙蝠物种的进化。这项工作整合了形式，功能和生态学，并为未来的工作奠定了基础，揭示了动物生物学的许多方面如何共同努力，推动“生命之树”的多样化。除了这项科学研究，该研究员将适应博物馆的展品和研究到科学学习的补充，为被监禁的学生谁是他们的高中同等学历的工作，并将担任导师的本科研究经验，在美国自然历史博物馆（AMNH）。该研究员的研究地址三个目标，以评估栖息生态学，翅膀形态学和着陆力学之间的联系。首先，这位研究员将使用微型计算机断层扫描（micro-CT）扫描来比较不同物种的翅膀惯性模式，这种模式产生了在降落过程中重新定位蝙蝠身体的力量。第二个目标评估种间差异，后肢骨骼几何形状与加载制度所施加的着陆冲击力。最后，这些数据将一起使用系统发育比较方法，以确定是否有基于分支的生态机会（栖息习惯），登陆生物力学，形态学和多样化率之间的联系登陆演习进行检查。通过这项研究，该研究员将通过使用AMNH的博物馆收藏品接受比较形态学和系统发育方法的培训。该研究员将致力于通过为被监禁的学生开发STEM学习补充材料，指导本科研究人员，以及通过公开提供研究产品来扩大科学参与。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估来支持。
