The International Research Fellowship Program enables U.S. scientists and engineers to conduct nine to twenty-four months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad. This award will support a twenty-four-month research fellowship by Dr. Brent P. Thoma to work with Prof. Peter K. L. Ng at the Raffles Museum of Biodiversity Research, National University of Singapore, Singapore, Republic of Singapore.This project aims to clarify the evolutionary relationships of the geographically widespread and taxonomically diverse superfamily of mud crabs known as Xanthoidea. The integration of studies on New and Old World taxa represents the largest genetic dataset of mud crabs, to date, with data for 10 genes from nearly 300 species. This information allows for the inference of evolutionary relationships of the mud crabs on a global scale in an effort to 1) test if the morphological characteristics currently used to delineate various xanthoid taxa reflect evolutionary relatedness or are the result of convergence, 2) determine if short branch lengths along the backbone of the xanthoid phylogeny are representative of a rapid radiation event that occurred early in the evolution of the mud crabs, and 3) infer the historical origins of potentially invasive or cryptogenic taxa.In addition to the obvious benefit of increased knowledge about the evolution of mud crabs, this research will help develop new international collaboration between the PI and research groups at Raffles Museum of Biodiversity Research and the National University of Singapore, Republic of Singapore (Prof. Peter K. L. Ng, Dr. Joelle C. Y. Lai, and Dr. J. C. Mendoza) and the University of Louisiana at Lafayette in Lafayette, Louisiana, USA (Prof. Darryl L. Felder).

国际研究奖学金计划使美国科学家和工程师能够在国外进行9至24个月的研究。该计划的奖项提供了联合研究的机会，以及使用国外独特或互补的设施，专业知识和实验条件。该奖项将支持一个为期二十四个月的研究奖学金博士布伦特P托马斯与教授彼得K。L. Ng在新加坡国立大学莱佛士生物多样性研究博物馆，新加坡，新加坡共和国。这个项目旨在阐明地理上广泛分布和分类上多样的泥蟹总科（Xanthoidea）的进化关系。对新大陆和旧大陆分类群的研究的整合是迄今为止最大的泥蟹遗传数据集，拥有来自近300个物种的10个基因的数据。这些信息允许在全球范围内推断泥蟹的进化关系，以1）测试目前用于描述各种黄质分类群的形态特征是否反映进化相关性或是趋同的结果，（二）确定是否短分支长度沿着骨干的黄质发育是一个快速的辐射事件，发生在早期的演变，这项研究除了可增加对青蟹演化的认识外，亦有助推动研究所与莱佛士生物多样性研究博物馆及新加坡国立大学的研究小组进行新的国际合作。L.
