Cypriniform Morphological Novelties: Origin, Performance, and Evolutionary Implications

项目名称：Cyriniform形态学新颖性：起源、表现和进化意义主要研究者：Hernandez， L. PatriciaNSF项目编号：IOS 1025845关键创新一直是进化生物学家感兴趣的，因为这些创新与适应性辐射有因果关系。鲤形鱼类约占所有淡水鱼的25%，其特征是与摄食有关的许多进化创新，这些创新可能导致了它们自己的适应性辐射。尽管鲤形鱼类在淡水生物群中占很大比例，但人们对这一多样化群体的摄食新奇性知之甚少。这个综合项目结合了分子发育技术、功能形态学方法和比较方法来研究鲤形形态新特征的起源和最终进化结果。不同的发展机制涉及到这些新奇的产生将使用分子技术进行研究。许多实验方法（高速录像、PIV和xrom）将被用来研究这些喂养新方法的功能影响。最后，比较方法将用于确定相关进化在鲤形动物中某些科的多样化中的作用。结果将阐明不同发育机制在进化新颖性起源中的作用，详细说明由不同发育机制产生的新颖性的性能影响，并确定相关进化在适应性辐射中的作用。这个进化-发展项目是独一无二的，它在几个层面上研究新颖性，从发育遗传水平开始，通过表现，最终到进化后果。该项目还具有重要的广泛影响，包括促进科学事业，对所有人员进行跨学科培训，继续招聘代表性不足的少数民族，以及在夏季研究项目中培训K-12教师使用斑马鱼进行简单实验。研究结果将在各种科学会议、大学演讲和针对小学生的一系列既定讲座中广泛传播。高速录像和发展技术将通过网络资源提供。

PROJECT TITLE: Cyriniform Morphological Novelties: Origin, Performance, and Evolutionary Implications PRINCIPAL INVESTIGATOR: Hernandez, L. PatriciaNSF Project #: IOS 1025845Key innovations have long been of interest to evolutionary biologists since such innovations are causally related to adaptive radiations. Cypriniform fishes, which comprise approximately 25% of all freshwater fishes are characterized by a number of evolutionary innovations associated with feeding that may have led to their own adaptive radiation. Although cypriniform fishes comprise an enormous proportion of the freshwater biota relatively little is known about the feeding novelties that characterize this diverse group. This integrative project combines molecular developmental techniques, functional morphological approaches, and comparative methods to investigate the origin and ultimate evolutionary consequences of cypriniform morphological novelties. The different developmental mechanisms involved in the generation of these novelties will be investigated using molecular techniques. A number of experimental approaches (high-speed video, PIV, and XROMM) will be used to investigate functional implications of these feeding novelties. Finally comparative methods will be used to determine the role of correlated evolution in the diversification of certain families within cypriniforms. Results will: clarify the role of different developmental mechanisms in the origin of evolutionary novelty, detail performance implications of novelties that have resulted from different developmental mechanisms, and determine the role of correlated evolution in adaptive radiations. This evo-devo project is unique in examining novelty at several levels starting from a developmental genetic level, through performance, and ultimately to evolutionary consequences.This project also has significant broader impacts including promoting careers in science, interdisciplinary training of all personnel, continued recruiting of underrepresented minorities, and training of K-12 teachers during summer research programs to do simple experiments using zebrafish. Results will be disseminated broadly at varied scientific meetings, university presentations, and an established series of lectures to elementary school students. High-speed videos, as well as developmental techniques, will be available via online sources.
