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.

项目标题：Cyriniform形态创新：起源、性能和进化影响首席研究员：Hernandez，L.PatriciaNSF项目#：iOS 1025845长期以来，进化生物学家一直对关键创新感兴趣，因为这种创新与适应性辐射有因果关系。鲤形鱼约占所有淡水鱼的25%，其特征是与摄食有关的一些进化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食性新颖性知之甚少。这个综合项目结合了分子发育技术、功能形态方法和比较方法来研究鲤形鱼类形态新奇的起源和最终的进化结果。这些新奇生物产生的不同发育机制将用分子技术进行研究。许多实验方法(高速视频、PIV和XROMM)将被用来研究这些喂养新奇事物的功能含义。最后，将使用比较方法来确定相互关联的进化在鲤科内某些家庭多样化中的作用。结果将：阐明不同发展机制在进化新颖性起源中的作用，详细说明不同发展机制导致的新颖性的表现含义，并确定相关进化在适应性辐射中的作用。这个EVO-DEVO项目在从发育遗传水平开始，通过表现，最终到进化结果的多个层面上考察新颖性方面是独一无二的。该项目还具有重大的更广泛的影响，包括促进科学职业生涯，对所有人员进行跨学科培训，继续招募代表不足的少数族裔，以及在暑期研究计划期间培训K-12教师使用斑马鱼进行简单的实验。结果将在不同的科学会议、大学演讲和为小学生举办的一系列讲座上广泛传播。高速视频以及开发技术将通过在线资源提供。
