Animal Behavior ProgramNontechnical AbstractProposal #: 9874608PI: Huber, RobertTitle: The behavioral mechanisms of hierarchy formation and the neurochemical correlates of aggression and dominance in crayfishHierarchical social structures are a widespread phenomenon in species ranging from anemones to humans and yet the behavioral processes that produce them remain poorly understood. This comprehensive study of dominance relationships will use crayfish to explore how animals modify their behavior in the context of aggressive interactions. This work will first characterize how previous fighting success modifies an organism's subsequent behavior in paired encounters. Since it is not intuitively obvious how relationships between such pairs develop into a complex social web in larger groups of animals, computer simulations of 'virtual' crayfish will explore more complex social structures. Predictions arising from these models will then be tested using real crayfish. Results from this project should provide considerable insight into the complex associations that exist between different levels of organization, including sensory processes, dispositions for aggression, dominance status, and brain chemistry. Given the theoretical significance, evolutionary importance, and broad taxonomic spread of aggression, elucidating the mechanisms of formation and maintenance of dominance inthese 'lower' animals will lead to a better understanding of the laws which govern social behavior. Results from this research may also have implications for the development of pharmaceuticals for the control of affective states, and for psychologists investigating the role of past experience in aggressive behavior.

动物行为计划非技术摘要提案编号：9874608PI：Huber，Robert标题：小龙虾中等级形成的行为机制以及攻击性和支配地位的神经化学关联等级社会结构是从海葵到人类的物种中普遍存在的现象，但产生它们的行为过程仍然存在不太了解。 这项对支配关系的综合研究将利用小龙虾来探索动物如何在攻击性互动的背景下改变自己的行为。 这项工作将首先描述先前的战斗成功如何改变有机体在配对遭遇中的后续行为。 由于在较大的动物群体中，这些配对之间的关​​系如何发展成复杂的社交网络并不直观，因此对“虚拟”小龙虾的计算机模拟将探索更复杂的社会结构。然后将使用真实的小龙虾来测试这些模型的预测。该项目的结果应该能够深入了解组织不同层次之间存在的复杂关联，包括感觉过程、攻击性倾向、支配地位和大脑化学反应。考虑到攻击性的理论意义、进化重要性和广泛的分类学传播，阐明这些“低等”动物统治地位的形成和维持机制将有助于更好地理解支配社会行为的法则。这项研究的结果也可能对开发控制情感状态的药物以及研究过去经验在攻击行为中的作用的心理学家产生影响。
