Dissertation Research: Fitness Components and Ontogenies in Complex Societies

研究人员将在哥斯达黎加对高度群居的棕松鸦进行研究。他们将采用遗传分析和追踪个体发生来确定可供年轻个体选择的繁殖选择的复杂性。这项研究是建立在对社会行为和人口密度之间关系的长期研究基础上的，自30年前人口开始增长以来，人口密度不断增加。这个社会的一个关键因素是延迟成熟和支配地位的信号所起的作用。通过了解不同的繁殖活动、领地遗传和分散和生存模式，将有助于阐明“亲代促进”假说。这些假设表明，在某些情况下，优势群体对其他群体的宽容可能是有利的。将棕松鸦作为群居鸟类的模型进行研究，将为脊椎动物的群居性提供一个明确的证明，这是一个主要的，但人们知之甚少的分支。研究人员将在哥斯达黎加对高度群居的褐松鸦进行研究。他们将使用基因O Q S UJ O Q!!!!F t Q （Times New Roman Symbol & Arial \ \ \ !）d !# = \ Q m S U O“我的名字是T Rabenold/Williams抽象伊丽莎白·贝伦斯伊丽莎白·贝伦斯

9311491 Rabenold The investigators will conduct a study of highly social brown jays in Costa Rica. They will employ genetic analyses and trace ontogenies to determine the complexity of breeding options available to young individuals. %%% This research builds on a long-term study of the relationship between social behavior and increasing density as this population has grown since its inception 30 years ago. A key element in this society is the role played by delayed maturation and the signaling of dominance status. By understanding differential reproductive activity, territory inheritance and patterns of dispersal and survival, light will be shed on the "parental facilitation" hypotheses. These hypotheses propose that tolerance by dominants by others might under some circumstances by favored. Study of brown jays as a model of social birds, will provide a definitive demonstration of a major, but poorly understood, branch of vertebrate sociality. *** ofbejays as a model of social birds 9311491 Rabenold The investigators will conduct a study of highly social brown jays in Costa Rica.
