One of the hallmarks of biological diversity is the unparalleled variation in form among species across taxonomic groups. Insights into the origin of new species and adaptation in the wild are often based on the characterization of morphological traits that enhance feeding, use of novel habitats, evading predators, or attracting mates. A core goal of this project is to determine how morphological traits are related to ecological function and exploitation of habitats. The research is based on the key concept of the form-function complex, which describes how morphology influences performance, ecology, and fitness. Thus, demonstrating the adaptive significance of a trait requires showing how it affects survival or reproduction. A second goal of this project is to demonstrate the role of morphology in predicting species habitat occupancy and community organization. Furthermore, the work will investigate how morphological traits drive diversification patterns as well as evaluate the adaptive basis of morphology by comparing disparity between clades that differ in species number.This project synthesizes ecomorphological approaches used in micro- and macroevolutionary analyses and makes available a large database to stimulate future research. The core data are derived from the PI's work on the covariation between morphology (900+ species) and physiological performance (300+ species) in ecological and evolutionary contexts using lizards as a model system. The published and unpublished data amassed over the past 30+ years will provide the largest synthetic analysis of ecomorphology across an extensive phylogenetic sample of species and provides the opportunity to test hypotheses regarding variation in trait diversification, whether morphological disparity promotes functional disparity, convergent evolution in form-function complexes and the roles of morphology and physiological traits in promoting adaptive radiations. Based on these data the analyses will 1) result in a comprehensive analysis of morphological diversification among major lizard clades, 2) test hypotheses pertaining to the influence of ecological traits (habitat, diet) in influencing phylogenetic diversification, morphological diversification, and functional diversification 3) estimate interspecific performance gradients using a phylogenetically informed analyses, 4) describe temporal and spatial variability of the performance gradient, and 5) determine the link between morphology, performance, and fitness using a long-term database. The results of the synthetic analysis of ecomorphological data will include the submission of a monograph. Concomitantly, the data associated with the synthesis will be made available as a phenotypic database to increase the accessibility to other researchers interested in ecomorphology.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.

生物多样性的标志之一是不同分类群的物种之间存在着无与伦比的形态差异。对新物种的起源和野外适应的深入了解通常基于形态特征的表征，这些形态特征可以增强摄食、利用新的栖息地、躲避捕食者或吸引配偶。该项目的核心目标是确定形态特征与生态功能和栖息地开发的关系。该研究基于形式-功能复合体的关键概念，它描述了形态如何影响表现、生态和健身。因此，证明一个性状的适应性意义需要展示它如何影响生存或繁殖。该项目的第二个目标是展示形态学在预测物种栖息地占用和群落组织中的作用。此外，这项工作还将研究形态特征如何驱动多样化模式，并通过比较物种数量不同的进化枝之间的差异来评估形态的适应性基础。该项目综合了用于微观和宏观进化分析的生态形态学方法，并提供了一个大型数据库来刺激未来的研究。核心数据源自 PI 使用蜥蜴作为模型系统，在生态和进化背景下研究形态（900 多个物种）和生理性能（300 多个物种）之间的协变的工作。过去30多年来积累的已发表和未发表的数据将提供对广泛的物种系统发育样本的生态形态学的最大综合分析，并提供机会检验有关性状多样化变异的假设、形态差异是否会促进功能差异、形式-功能复合体的趋同进化以及形态和生理性状在促进适应性辐射中的作用。基于这些数据，分析将1）对主要蜥蜴分支之间的形态多样性进行全面分析，2）测试与生态特征（栖息地，饮食）对系统发育多样化，形态多样化和功能多样化的影响有关的假设，3）使用系统发育信息分析估计种间性能梯度，4）描述性能的时间和空间变异性 梯度，5) 使用长期数据库确定形态、性能和健身之间的联系。生态形态数据综合分析的结果将包括提交专着。与此同时，与合成相关的数据将作为表型数据库提供，以增加对生态形态学感兴趣的其他研究人员的可及性。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标准进行评估，被认为值得支持。
