DESCRIPTION (Adapted from applicant's abstract): This ADAHMA RSDA proposal is a request for a 5-year K02 renewal. The original funded K02 proposal described a research plan designed to evaluate the relationship of within family aggression, conflict, and cooperation to kinship asymmetries (from alternative reproductive tactics) and the relationship of these variables to parental allocation tactics and dispersal of offspring, variables that mediate social behavior in one species. The research will experimentally manipulate wild-living and laboratory populations of several model species. The current proposal is in three parts: Part 1 describes continuing experimental manipulations to evaluate both proximately and ultimately how aggression, paternal provisioning, and genetic parentage are related in eastern bluebirds, Sialia Sialis. Part 2 describes an experimental test of a new hypothesis that links social monogamy with multiple mating by females, which will be tested initially in three species of bluebirds (Sialia sp), and later several non cavity nesting thrushes and cavity nesting non thrushes. Part 3 will test in multiple species through collaborative research the evolutionary function of freely expressed female choice, specifically the hypothesis that freely expressed female choice increases the quality and viability of females' offspring. The specific aims of Part 1 are 1) to evaluate if male-male aggression during females' fertile periods currently functions to decrease the likelihood that females' broods will be sired by other than her territorial partner. 2) Mate guarding by males is a facultative response to behavioral variation of females or ecological circumstances that increase the likelihood that females mate with more than one male. 3) Paternal provisioning of nestlings varies facultatively as a function of the behavior of fertile females. The specific aims of Part 2 are to experimentally evaluate in three species of bluebirds the relationship of extra pair paternity, patterns of multiple mating by females, and variance in male reproductive success to intrinsic quality of females and the quality of the environments females are in. The specific aims of Part 3 are to evaluate the effects of free female choice on the quality and viability of offspring in a number of species. Further research development plans include national and international collaborations with scientists whose technical skills or knowledge of particular species will enhance the achievement of the research aims. The candidate's mentoring activities focus not only on students and postdoctoral scientists in ecology, genetics, and zoology, but notably on undergraduate and graduate students in Womens' Studies - a group with individuals often antagonistic towards science. She encourages students and others to understand the significant and important sources of overlap in concerns, methods, and outcomes of evolutionary biology and feminism. She will continue her outreach to women and minority students in a variety of ways.

描述（改编自申请人摘要）：本ADAHMA RSDA提案 申请K 02的5年更新。 原K 02提案 描述了一项研究计划，旨在评估 家庭攻击，冲突，合作，亲属关系不对称（从 替代生殖策略）以及这些变量与 父母的分配策略和后代的分散，变量， 调节一个物种的社会行为。 这项研究将实验性地 操纵几个模式物种的野生和实验室种群。 目前的建议分为三个部分：第一部分描述了继续 实验操作，以评估probability和最终如何 攻击性、父源供给和遗传亲子关系与 东部蓝知更鸟，西亚利亚西亚利斯。 第2部分描述了一个实验测试， 一种新的假说，将社会一夫一妻制与雌性的多次交配联系起来， 其最初将在三种蓝知更鸟（Sialia sp）中进行测试， 后来又有几种非穴巢画眉和穴巢非 画眉 第3部分将通过协作在多个物种中进行测试 研究自由表达的女性选择的进化功能， 特别是自由表达的女性选择增加 雌性后代的质量和生存能力。 第一部分的具体目的是：1）评估男性之间的攻击性是否 在女性的生育期，目前的功能，以减少 雌性的后代可能不是由她的领地 搭档 2)雄性守卫配偶是一种对行为的任意反应 女性或生态环境的变化，增加了 女性与不止一个男性交配的可能性。 3)父系 雏鸟的供给能力随着行为的变化而变化 有生育能力的女性 第2部分的具体目标是通过实验 评估三种蓝鸟中额外对的关系 父系、雌性多次交配的模式和雄性的变异 繁殖成功的内在质量的女性和质量的 女性所处的环境 第3部分的具体目标是评估 雌性自由选择对后代质量和生存能力的影响 在许多物种中。 进一步的研究发展计划包括国家和国际 与科学家的合作，他们的技术技能或知识， 特定物种将促进研究目标的实现。 的 候选人的指导活动不仅关注学生和博士后 科学家在生态学，遗传学和动物学，但特别是在本科 和研究生在妇女研究-一组与个人往往 对科学持敌对态度。 她鼓励学生和其他人 理解重叠关注的重要和重要来源， 进化生物学和女权主义的方法和结果。 她将 继续以各种方式与妇女和少数民族学生接触。
