Susan C. Alberts and Jeanne Altmann: Proposal number 0322781(Altmann)/0322613(Alberts), Collaborative Research: Relationship among demographic, social and genetic structure. Behavior plays a pivotal role in survival and reproduction. Its immediate, short-term impact is in maintaining homeostasis and organismal integrity as behavior provides the individual with a mechanism of rapid and flexible response to changes in its internal and external environments. Even more profound is behavior's long-term impact on the lives of individuals and on the evolutionary trajectories of populations. The main long-term objective of the investigators is to develop a comprehensive picture of how behavior shapes fitness outcomes and population processes in one population of wild mammals - the savanna baboons of the Amboseli basin in east Africa. The proposed work not only will accomplish important short-term goals but will reach overtly toward the long-term ones as well.The overall conceptual framework is an integrative socioecology that is sensitive to the intrinsic interdependencies among behavior, physiology, genetic structure, and demography. During the next three years, the research will (1) probe more deeply into the function and lifetime development of relationships through individuals' paternal as well as maternal lineage and (2) continue to delineate sources of lifetime fitness differences for both sexes. This will be accomplished by testing eight explicit predictions derived from three hypotheses. For females, these relate to the impact of social status and of paternal and maternal relatives on fitness. For males they address the relationship between mating success and paternity success, the role of male mate choice in paternity success, and the direct behavioral contributions that males make to the survival of their offspring. Genetic and physiological analyses are based on non-invasive biological sampling and associated assay and genotyping techniques, the development and refinement of which have been a cornerstone of these research groups.

Susan C. Alberts和Jeanne Altmann：提案号0322781(Altmann)/0322613(Alberts)，合作研究：人口，社会和遗传结构之间的关系。行为在生存和繁殖中起着关键作用。它的直接、短期影响是维持体内平衡和机体完整性，因为行为为个体提供了一种对内部和外部环境变化做出快速、灵活反应的机制。更深刻的是行为对个体生活和种群进化轨迹的长期影响。研究人员的主要长期目标是对一种野生哺乳动物种群——东非安博塞利盆地的热带草原狒狒——的行为如何影响适应性结果和种群过程形成一个全面的图景。拟议的工作不仅将实现重要的短期目标，而且将明显地达到长期目标。总体概念框架是一个综合的社会生态学，它对行为、生理、遗传结构和人口统计学之间的内在相互依赖性很敏感。在接下来的三年里，研究将(1)通过个体的父系和母系谱系更深入地探索人际关系的功能和终身发展；(2)继续描述两性终生健康差异的来源。这将通过测试来自三个假设的八个明确预测来完成。对于女性来说，这与社会地位以及父系和母系亲属对健康的影响有关。对于雄性，他们探讨了交配成功和父权成功之间的关系，雄性配偶选择在父权成功中的作用，以及雄性对后代生存的直接行为贡献。遗传和生理分析基于非侵入性生物取样和相关的分析和基因分型技术，这些技术的发展和完善一直是这些研究小组的基石。
