Through an integrative study of DNA sequences and morphological features, including the use of high-resolution computer tomography, we will study the adaptations to terrestrial and arboreal lifestyles in a large group of amphibians - the worldwide-distributed narrow-mouthed frogs (Microhylidae). Microhylids are not entirely restricted to the water for breeding, and many groups have completely abandoned the need of water for reproduction. Examination of anatomical adaptations related to this transition (aquatic to terrestrial breeding) in these frogs can help us understand the evolution of terrestriality in vertebrates as a whole.Results and data associated with this research will be broadly disseminated for both the scientific community and general public through a variety of outlets (scientific journals, newspapers, internet). Curriculum material will be developed together with the Department of Education the American Museum of Natural History (AMNH) as part of the Science Research Mentoring and the Research Experience for Undergrads program at the AMNH, introducing high school and undergrad students to moderns research topics and techniques.

通过对DNA序列和形态特征的综合研究，包括使用高分辨率计算机断层扫描，我们将研究一大类两栖动物-世界各地分布的窄口蛙（Microhylidae）对陆地和树上生活方式的适应。 小水螅并不完全局限于水来繁殖，许多群体已经完全放弃了对水的繁殖需求。通过对这些蛙类从水生到陆生的转变过程中的解剖学适应性的研究，可以帮助我们理解脊椎动物陆生性的进化。与这项研究相关的结果和数据将通过各种渠道（科学期刊、报纸、互联网）向科学界和公众广泛传播。课程材料将与美国自然历史博物馆（AMNH）教育部一起开发，作为AMNH本科生科学研究指导和研究经验计划的一部分，向高中和本科生介绍现代研究主题和技术。
