Trumbo, Stephen IBN-9420985 NON-TECHNICAL SUMMARY Behavioral flexibility is the key to relating behavior to ecology and to reproductive success. The research proposed here will develop the first invertebrate model of a biparental organism for studying the behavioral and hormonal mechanisms that regulate reproductive behavior. Blood levels of juvenile hormone will be determined and correlated with detailed changes in parental behavior. Topical application of juvenile hormone will be used to test the hypothesis that increased male parental effort will increase the rate of larval development and lead to a decrease in parental effort by the male's partner. Hormone levels will also be measured during competitive interactions between two females to test the hypothesis that contests for the breeding resource result in elevated levels of juvenile hormone. Furthermore, Juvenile hormone will be administered to subordinate females during competition for resources to examine hormonal influences on dominance, reproductive output and parental contributions to broods of mixed parentage. This study will be based on an already thorough understanding of behavioral variation in the animals in a natural ecological context. The ability to integrate behavioral and physiological analyses in a group amenable to experimental manipulation will contribute to a broader understanding of the flexibility of reproductive behavior. The proposed project promises to advance our understanding of how complex sequences of behavior are organized, and how behavioral flexibility contributes to effective parental care.

Trumbo，Stephen IBN-9420985 非技术性总结 行为灵活性是将行为与生态和繁殖成功联系起来的关键。 这里提出的研究将开发出第一个双亲生物的无脊椎动物模型，用于研究调节生殖行为的行为和激素机制。 将测定保幼激素的血液水平，并将其与父母行为的详细变化相关联。 保幼激素的局部应用将被用来测试的假设，即增加雄性父母的努力将增加幼虫发育的速度，并导致减少父母的努力，由男性的合作伙伴。 激素水平也将在两个雌性之间的竞争性相互作用，以测试的假设，竞争的繁殖资源导致保幼激素水平升高。 此外，保幼激素将被管理到下属的女性在竞争资源，以检查激素的优势，生殖输出和父母的贡献，混合亲子关系的育雏的影响。 这项研究将基于对自然生态环境中动物行为变化的深入了解。 将行为和生理分析整合到一个易于实验操作的群体中的能力将有助于更广泛地理解生殖行为的灵活性。 拟议中的项目有望促进我们对复杂的行为序列是如何组织的，以及行为灵活性如何有助于有效的父母照顾的理解。
