项目摘要

Noctilionoid bats comprise more than 200 species that span nearly the entire ecological diversity of land mammals. They range from tiny insectivores and nectarivores to large carnivores, and even vampire bats. This superfamily provides an unparalleled system for understanding how, when, and where bats evolved new diets, changed roosting habits and developed different kinds of echolocation. This project will use DNA sequences and comparison of morphological variations to reconstruct evolutionary relationships among these bats, including the fossils of 20 extinct species. Together with powerful methods for estimating the timing of historical events, this extensive fossil series will provide a timeline for investigating patterns and processes of ecological adaptation, speciation, and extinction across all species. This project will mentor and train postgraduate, graduate, and undergraduate students in molecular and morphological laboratory techniques and research methods. The data generated during the course of this study -- including photographs and DNA sequences -- will be freely available to the public through existing databases and online repositories heavily used by educators at all levels. Extensive documentation of morphological data through Morphobank will facilitate future research. Finally, this project will provide a robust framework for exploring the mechanisms driving ecological and species diversity in a hyperdiverse group of mammals.

夜氨酸型蝙蝠包括200多种物种，这些物种几乎涵盖了陆地哺乳动物的整个生态多样性。它们的范围从微小的食虫动物和蜜饯到大型食肉动物，甚至是吸血鬼蝙蝠。这个超家族提供了一个无与伦比的系统，用于了解蝙蝠如何，何时和何处如何进化新饮食，改变栖息的习惯并开发出不同种类的回声定位。该项目将使用DNA序列和形态变化的比较来重建这些蝙蝠之间的进化关系，包括20种灭绝物种的化石。加上估计历史事件时间的有力方法，这个广泛的化石系列将为研究所有物种的生态适应，物种形成和灭绝的模式和过程提供时间表。该项目将指导和培训分子和形态实验室技术和研究方法的研究生，研究生和本科生。在本研究过程中生成的数据（包括照片和DNA序列）将通过现有数据库和在线存储库免费提供，并在各级教育工作者大量使用。通过Morphobank对形态数据的广泛文献将促进未来的研究。最后，该项目将提供一个强大的框架，用于探索在哺乳动物群中推动生态和物种多样性的机制。
