A seemingly simple but significan question is, whether in responses to drug treatment or behavioral interactions, why do different individuals respond differently? Research on fish and other vertebrates has demonstrated consistent inter-individual differences in behaviors such as boldness and aggression. These inter-individual differences in behavior have been termed animal personalities. The work conducted under this award examines the ecological consequences of individual behavioral variation in largemouth bass, an important North American sport fish. To date, only a handful of studies have investigated the relationship between personality traits and various components of fitness in the field, and even fewer studies have investigated whether inter-individual differences in behavior are consistent across life stages. Fish are excellent study organisms to investigate the impact of personality traits on growth, survival, and reproductive success at different life stages. The work conducted under this award will use DNA-based paternity analysis to examine how variation in shy/bold behavior affects various components of fitness in largemouth bass under field conditions. These field studies focus on juvenile growth and survival, adult male and female reproductive success, heritability of personality types, and the fitness tradeoffs of shy/bold personality types across life stages. Bass are one of the most economically important sport fish in North America and the results of this research will help inform decision makers on how to better manage these and other fish species. Although the evolutionary impacts of commercial harvest on fish populations are well-recognized, the effects of recreational angling (including catch and release fishing) on fish population are largely unknown. Research conducted under this award will directly address how recreational angling affects bass behaviors and reproductive success. Results from this research will be communicated through presentations and publications to scientific and non-scientific audiences, including secondary school students through K-12 education programs at the Kellogg Biological Station.Data used in publications from this project will be deposited into DRYAD (http://datadryad.org)

一个看似简单但意义重大的问题是，无论是对药物治疗的反应还是对行为互动的反应，为什么不同的个体反应不同？对鱼类和其他脊椎动物的研究表明，个体之间在大胆和攻击性等行为上存在一致的差异。这些个体间的行为差异被称为动物性格。在这个奖项下进行的工作研究了大口黑鲈个体行为变化的生态后果，大口黑鲈是一种重要的北美运动鱼。迄今为止，只有少数研究调查了人格特征与该领域各种健康成分之间的关系，而调查个体间行为差异在生命阶段是否一致的研究就更少了。鱼类是研究人格特征对不同生命阶段的生长、生存和繁殖成功的影响的优秀研究生物。根据该合同进行的工作将使用基于dna的父系分析来研究在野外条件下，大口黑鲈害羞/大胆行为的变化如何影响适合度的各个组成部分。这些实地研究集中在幼年动物的生长和生存、成年雄性和雌性的生殖成功、性格类型的遗传能力以及羞怯/大胆性格类型在生命阶段的适应性权衡。鲈鱼是北美经济上最重要的运动鱼类之一，这项研究的结果将有助于决策者更好地管理这些鱼类和其他鱼类。虽然商业捕捞对鱼类种群的进化影响是公认的，但休闲垂钓（包括捕捞和放生）对鱼类种群的影响在很大程度上是未知的。在该奖项下进行的研究将直接研究休闲钓鱼如何影响鲈鱼的行为和繁殖成功。这项研究的结果将通过演讲和出版物传达给科学和非科学受众，包括通过凯洛格生物站K-12教育项目的中学生。本项目出版物中使用的数据将存入DRYAD （http://datadryad.org）。
