0076202SchultheisThe International Research Fellow Awards Program enables U.S. scientists and engineers to conduct three 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 provide Dr. Alicia S. Schultheis with support for twelve months to work with Dr. Jane Hughes at Griffith University in Brisbane, Australia.This one-year study will use molecular techniques developed by Dr. Schultheis to determine how adult dispersal and differences in life history affect the genetic structuring of Australian stream insect populations. They will address whether 1) adult flight operates as an effective large-scale dispersal mechanism across areas of fragmented adult (terrestrial) habitat?, and 2) are fine-scale patterns of genetic differences among larval populations of stream insects the result of limited in-stream movement and patchy oviposition? Besides leading to a better understanding of the effects of genetic structuring, it will also provide valuable information about whether fragmentation of the surrounding forest affects stream insect populations by disrupting adult dispersal. The study will provide a framework in which to begin studying similar processes in streams throughout the world, including temperate streams of North America.Dr. Hughes and her colleagues have generated a unique set of data regarding dispersal and genetic structure of stream insects that is not available elsewhere. Their data provide the only system in which effects of life history of these insects can be studied.***

0076202 Schultheis国际研究员奖励计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。 该计划的奖项提供了机会，联合研究，并使用独特的或互补的设施，专业知识和实验条件国外。这项为期一年的研究将使用Schultheis博士开发的分子技术来确定成虫的传播和生活史的差异如何影响澳大利亚溪流昆虫种群的遗传结构。他们将解决1）成虫飞行是否是在支离破碎的成虫（陆地）栖息地地区有效的大规模传播机制？，溪流昆虫幼虫种群间遗传差异的精细模式是否是有限的溪流内移动和斑片状产卵的结果？ 除了导致更好地了解遗传结构的影响，它也将提供有价值的信息，是否破碎化的周围森林影响流昆虫种群扰乱成年人的传播。 这项研究将为开始研究包括北美温带溪流在内的世界各地溪流中的类似过程提供一个框架。休斯博士和她的同事们已经生成了一套独特的关于溪流昆虫传播和遗传结构的数据，这是其他地方所没有的。 他们的数据提供了研究这些昆虫生活史影响的唯一系统。
