9901202 Boughman The International Research Fellow Awards Program enables U.S. scientists and engineers to conduct three to twenty-four months of research aboard. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions aboard. This award will provide Dr. Janette W. Boughman with support for twelve months to work with Dr. Dolph Schluter at the University of British Columbia's Department of Zoology. Dr. Boughman will study the divergent sexual selection of Stickleback fish, testing costs and benefits of condition dependent handicaps in two populations. The signals used to select mates can be influenced by the local environment, possibly leading to divergence. This work will describe and compare reproductive benefits and viability costs of signalling in two light environments. These results are important to the understanding of speciation (reproductive isolation). The host, Dr. Schluter, is renowned for his work measuring selection in natural populations and identifying the selective forces shaping morphology and behavior.***

9901202鲍曼国际研究员奖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。该项目的奖项提供了联合研究的机会，并提供了使用独特或互补的设施、专业知识和实验条件的机会。这项奖励将为珍妮特·W·鲍曼博士提供为期12个月的支持，以便与不列颠哥伦比亚大学动物系的多尔夫·施卢特博士合作。鲍曼博士将研究针叶鱼不同的性别选择，在两个种群中测试条件依赖性障碍的成本和收益。用于选择配偶的信号可能会受到当地环境的影响，可能会导致分歧。这项工作将描述和比较两种光环境下信号传递的生殖效益和生存成本。这些结果对于理解物种形成(生殖隔离)很重要。主持人施卢特博士以测量自然种群中的选择和识别塑造形态和行为的选择性力量而闻名。
