9802812 Pope The 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 support a twenty-four-month postdoctoral research visit by Dr. Denise S. Pope to work with Dr. John Christy at the Smithsonian Tropical Research Institute in Balboa, Panama. Dr. Pope will use fiddler crabs as a model system to study the theories of sexual selection and animal communication to understand the evolution of sexually dimorphic exaggerated traits. Using signal detection theory, she will study the claw waving display of male fiddler crabs, which is done to threaten other males and to attract females for mating. Her studies will use a video playback technique for the presentation of stimuli. She will present females with videos of displays produced by males in different situations, and against different backgrounds. This test will distinguish between female preference for detectability and female preference for a more exaggerated signal. Dr. Christy has studied sexual selection and communication in fiddler crabs for twenty years. The Smithsonian Tropical Research Institute has well-equipped facilities, and provides a location where these crabs are found in the greatest diversity and where the genus is thought to have originated. ***

小行星9802812 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。 该奖项将支持丹妮丝博士为期24个月的博士后研究访问。波普将与巴拿马巴尔博亚史密森热带研究所的约翰·克里斯蒂博士一起工作。 波普博士将使用招潮蟹作为模型系统，研究性选择和动物交流的理论，以了解性二形夸张性状的进化。 她会利用讯号侦测理论，研究雄性招潮蟹挥舞爪子的动作，以威胁其他雄性招潮蟹及吸引雌性招潮蟹交配。 她的研究将使用视频回放技术来呈现刺激。 她将向女性展示男性在不同情况下和不同背景下制作的视频。 该试验将区分女性对可检测性的偏好和女性对更夸张信号的偏好。 克里斯蒂博士研究招潮蟹的性选择和交流已经有20年了。 史密森尼热带研究所拥有设备齐全的设施，并提供了一个位置，这些螃蟹被发现在最大的多样性和属被认为是起源。 ***
