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

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，以及使用独特或互补的设施，专业知识和国外的实验条件。贝尔与费利西蒂·A博士合作。该项目是对三棘鱼行为综合征的研究，三棘鱼是一种分布广泛的淡水鱼，非常适合测试进化假说。 PI将从三个方面研究个体和群体之间的大胆和侵略性差异。 首先，她将确定大胆和侵略性是否在捕食风险不同的一些种群中也有类似的相关性。 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密切相关的。 第三，她将从系统发育的角度研究“大胆-攻击性”综合征在人群中的演变，以询问为什么这些特征在某些人群中相关，而在其他人群中则不相关。

0301899BellThe International Research Fellowship 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 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.
