Molecular and Morphological Systematics of the Australian Genera of Freshwater Crayfish (Decapoda: Parastacidae)

9418425希利斯和克兰德尔这笔奖金将支持基思·A·克兰德尔博士前往澳大利亚的三个月的旅费。克兰德尔博士和德克萨斯大学奥斯汀分校动物系的大卫·M·希利斯博士正在与澳大利亚维多利亚州沃南布尔的迪肯大学水产科学和自然资源管理学院的克里斯·奥斯汀博士进行合作研究。这项研究将为了解淡水小龙虾家族的系统学和进化生物学提供信息。这次旅行的目的是收集一系列的对二甲酸小龙虾，为它们的系统发育的形态/分子研究做准备。一旦系统发育被开发出来，它将被用来检验早期关于系统发育关系和生物地理学的假说。这项研究还将产生一些数据，这些数据应该对针对这些动物的保护活动有用。奥斯汀博士将他在澳大利亚小龙虾的形态和地理分布方面的专业知识带到了合作中。美国研究人员在分子系统技术方面做出了相当大的贡献。

9418425 Hillis and Crandall This award will support the travel expenses for three months of Dr. Keith A. Crandall to Australia. Dr. Crandall, along with Dr. David M. Hillis of the Department of Zoology at the University of Texas, Austin, are conducting collaborative research with Dr. Chris Austin of the School of Aquatic Science and Natural Resource Management at Deakin University in Warrnambool, Victoria, Australia. The study will provide information to assist in understanding the systematics and evolutionary biology of a family of freshwater crayfishes. The purpose of the travel is to collect a series of parastacid crayfish in preparation for a morphological/molecular study of their phylogeny. Once the phylogeny has been developed it will be used to test earlier hypotheses on phylogenetic relationships and biogeography. The study will also yield data that should be useful in conservation activities directed at these animals. Dr. Austin brings to the collaboration his expertise on the morphology of Australian crayfish and their geographic distribution. The American investigators have considerable contributions in molecular systematic techniques.
