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.

本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个雄心勃勃的实地项目， 行为研究的具体目标和方法论是 现代化的描述--无论是近端的还是最终的-- 家庭内的攻击、冲突和合作 亲属关系的不对称性（由替代生殖策略引起） 以及这些变量与个体的关系 行为，如父母的分配策略和后代的分散， 它可以调节和控制个体社会组织。 具体目标是：（1）评估孕产不确定的程度， 使用血液DNA指纹和孟德尔遗传简单模型的亲子鉴定 遗传学; 2）评估家庭内亲属关系， 男性和女性的攻击行为; 3）评估潜在的来源 包括资源丰富度，以前的历史，激素 条件等，女性和男性的攻击行为; 4） 描述在繁殖期间雌性和雄性的正常激素概况 季节和实验性地操纵荷尔蒙条件， “挑战”测试; 5）评估可能的反策略，以不确定的 亲子关系，即照顾者是否承认亲属与非亲属鸡蛋， 雏鸟; 6）评估性别之间的互动模式 照顾者和后代;和7）评估近端和最终 纳塔尔和繁殖分散的原因。 这些研究目标的实现将使该计划成为 研究社会行为的主要项目。研究发展计划 包括与那些在技术上 技能是具体的;被提名人打算制作一系列论文， 一本关于东部蓝知更鸟行为生态学的专著， 关于社会行为的论文被提名人的其他计划 专业活动包括参与专业协会， 这些角色直接影响她自己和其他人的研究活动。
