项目摘要

Species morphology typically evolves to meet the demands of the environment. In the fossil record, and among existing species, large morphological changes are frequently associated with changes in habitat or ecology. However, there remains little understanding of the general rules that govern morphological change associated with ecological change. This project will use skeletal and soft-tissue anatomy as well as detailed 3D shape data to study closely-related, transitional species to investigate the evolution of morphology and ecology in the long-lived and fossil-rich group Crocodylomorpha (crocodiles, alligators, and their extinct relatives). The project will exploit the group's multiple natural experimentation with extreme environments to develop detailed conceptual models for major ecological and morphological transitions that will inform on the rules underlying morphological change. These models will then serve as predictors for how and why transformations occur, which can be tested in other groups with similar narratives. Important examples include the initial emergence of four-limbed vertebrates onto land, how birds took the sky, and the first steps in the reign of mammals. The innovative technologies, techniques, and widely applicable conclusions from this research will promote interdisciplinary work among paleontologists, biomechanists, ecologists, and evolutionary biologists. The researchers will make their data, digital models, analytical tools, and essential supplementary files available for wide access. Furthermore, this project will support associated PhD and Postdoctoral research as well as foster access to higher education for substantially underrepresented groups.This project will use integrative approaches to reveal the complexities of ecomorphological changes across major evolutionary transitions. The study will examine how novel environments put new, often extreme demands on historical phenotypes by addressing how large-scale habitat and ecological transitions drive evolution across multiple integrated anatomical systems. The research will test hypotheses about phenotypic integration on an evolutionary scale to determine whether developmental rates, sequence heterochrony, and/or patterns of modularity determine if consistently applied rules of ecomorphological diversification underlie adaptive radiations. The outcome will be an unprecedented database of crocodylomorph cranial and post-cranial diversity that includes contrast-enhanced neural and skeletal tissues, raw and partitioned CT stacks, and 3D digital models as well as comparative, intra-clade conceptual models for how predatory vertebrates shift to lives on the shoreline, within the sea, and toward herbivory. The microCT and cutting-edge, diffusible iodine-based contrast-enhanced computed tomography imaging, in addition to a robust morphological phylogeny for analysis of evolutionary trends using the latest phylogenetic methods, represent potentially transformative methodologies developed by this research group.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.
物种形态通常会进化以满足环境的需求。在化石记录和现有物种中,大的形态变化常常与栖息地或生态的变化有关。然而,人们对与生态变化相关的形态变化的一般规则仍然知之甚少。该项目将利用骨骼和软组织解剖学以及详细的 3D 形状数据来研究密切相关的过渡物种,以研究长寿且化石丰富的鳄鱼类(鳄鱼、短吻鳄及其已灭绝的近亲)的形态和生态演化。该项目将利用该小组在极端环境下进行的多项自然实验,为主要生态和形态转变开发详细的概念模型,从而揭示形态变化的基本规则。然后,这些模型将作为转型如何以及为何发生的预测器,可以在具有类似叙述的其他群体中进行测试。重要的例子包括四肢脊椎动物最初出现在陆地上、鸟类如何飞上天空,以及哺乳动物统治的第一步。这项研究的创新技术、技巧和广泛适用的结论将促进古生物学家、生物力学学家、生态学家和进化生物学家之间的跨学科工作。 研究人员将提供他们的数据、数字模型、分析工具和重要的补充文件以供广泛访问。此外,该项目将支持相关的博士和博士后研究,并促进代表性不足的群体获得高等教育的机会。该项目将采用综合方法来揭示重大进化转变中生态形态变化的复杂性。该研究将通过解决大规模栖息地和生态转变如何驱动多个集成解剖系统的进化来研究新环境如何对历史表型提出新的、往往是极端的要求。该研究将在进化规模上测试有关表型整合的假设,以确定发育速率、序列异时性和/或模块化模式是否决定了生态形态多样化的一致应用规则是否是适应性辐射的基础。其成果将是一个史无前例的鳄鱼型颅骨和颅后多样性数据库,其中包括对比增强的神经和骨骼组织、原始和分区的 CT 堆栈、3D 数字模型以及比较性的进化枝内概念模型,用于了解掠食性脊椎动物如何转向海岸线、海洋内和食草性生活。 microCT 和尖端的基于扩散碘的对比增强计算机断层扫描成像,以及使用最新系统发育方法分析进化趋势的强大形态系统发育学,代表了该研究小组开发的潜在变革方法。该奖项反映了 NSF 的法定使命,并通过使用基金会的智力价值和更广泛的影响审查进行评估,被认为值得支持 标准。
