International Research Fellowship Program: Differences Between Individuals and Populations of Threespined Stickleback in Boldness and Agressiveness

贝尔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，并利用国外独特或互补的设施、专业知识和实验条件。该奖项将支持艾莉森·M·贝尔博士与英国格拉斯哥大学的费利西蒂·A·亨廷福德博士合作的为期24个月的研究奖学金。该项目是对三刺鱼行为综合症的研究，三刺鱼是一种分布广泛的淡水鱼，非常适合测试进化假说。PI将通过三种方式研究个体和群体在大胆和攻击性方面的差异。首先，她将确定在捕食风险不同的一些种群中，大胆和攻击性是否具有类似的相关性。其次，她将研究这两种行为背后的生理机制，以推断这两种特征可能是如何近距离相关的。第三，她将用系统发生学的观点来研究整个种群中“大胆-攻击性”综合症的进化，以询问为什么这些特征在一些种群中是相关的，而在另一些种群中却没有。

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. Alison M. Bell to work with Dr. Felicity A. Huntingford at the University of Glasgow in Glasgow, United Kingdom.This project is a study of a behavioral syndrome in threespined stickleback, a widely-distributed freshwater fish well-suited for testing evolutionary hypotheses. The PI will study differences between individuals and populations for boldness and aggressiveness in three ways. First she will ascertain whether boldness and aggressiveness are similarly correlated in a number of populations which differ in predation risk. Second, she will investigate a physiological mechanism underlying both behaviors in order to infer how the two traits might be related proximally. Third she will examine the evolution of the 'boldness-aggressiveness' syndrome across the populations with a phylogenetic perspective to ask why the traits are correlated in some populations but not others.
