This ADAMHA RCDA (Level II) proposal describes a comprehensive research plan that will result in completion of an ambitious field project on social behavior. The specific aims and methodologies of the research are headed toward a modern characterization - in both proximate and ultimate terms - of the relationship of within family aggression, conflict, and cooperation to kinship asymmetries (arising from the alternative reproductive tactics of individuals) and the relationship of these variables to individual behavior, such as parental allocation tactics and dispersal of offspring, that may mediate and control individual social organization. The specific aims are: 1) to assess the degree of uncertain maternity and paternity using DNA-fingerprinting of blood and simple models of Mendelian genetics; 2) To evaluate the relationship of within family kinship to aggressive behavior of males and females; 3) To evaluate potential sources of variation, including resource abundance, previous history, hormonal condition, etc., in aggressive behavior of females and males; 4) To describe normal hormonal profiles of females and males during the breeding season and to experimentally manipulate hormonal condition using "challenge" tests; 5) To assess a possible counter-strategy to uncertain parentage, namely whether caregivers recognize kin versus nonkin eggs and nestlings; 6) To assess the patterns of gender interactions between caregivers and offspring; and 7) To evaluate the proximate and ultimate causes of natal and breeding dispersal. The achievement of these research objectives will establish this program as a major program in the study of social behavior. Research development plans include the establishment of collaborations with scientists whose technical skills are specific; the nominee intends to produce a series of papers and a monograph on the behavioral ecology of eastern bluebirds and several general papers on social behavior. The nominee's plans for other professional activities include involvement in professional societies in roles that directly affect her own research activities and those of others.

这份ADAMHA RCDA(二级)提案描述了一项全面的研究 该计划将导致完成一项雄心勃勃的社会问题实地项目 行为。研究的具体目标和方法是前瞻的。 走向现代的特征--无论是直接的还是终极的-- 关于家庭内部的攻击性、冲突和合作的关系 亲属关系不对称(由另一种生育策略引起 个体)以及这些变量与个体的关系 行为，如父母分配策略和后代的分散， 可能调解和控制个人社会组织的人。 具体目标是：1)评估产妇的不确定程度和 孟德尔血型DNA指纹和简单模式的亲子鉴定 遗传学；2)评估家庭内亲属关系与 男性和女性的攻击行为；3)评估潜在的来源 变异，包括资源丰度，既往病史，荷尔蒙 男女攻击性行为的状况等；4) 描述雌性和雄性在繁殖过程中的正常荷尔蒙状况 并通过实验来控制荷尔蒙状况 “挑战”测试；5)评估对不确定因素的可能对策 亲子关系，即照顾者是否识别亲缘关系和非亲缘关系 雏鸟；6)评估性别之间的互动模式 照顾者和后代；以及7)评估最近和最终的 出生和繁殖扩散的原因。 这些研究目标的实现将使该计划成为 研究社会行为的一个主要项目。研究发展计划 包括与科学家建立合作关系，这些科学家的技术 技能是具体的；被提名者打算制作一系列的论文和 东方蓝知更鸟行为生态学专著及几种 关于社会行为的一般论文。被提名人的其他计划 专业活动包括参与专业协会 直接影响她自己和其他人的研究活动的角色。
