群居动物生活在复杂的物理和社会环境中，这要求它们通过改变行为来关注和快速响应社会和环境信息。一个关键的社会影响是等级或地位，这是动物社会中普遍存在的因素。等级通常控制着生殖和其他资源的获得，以及对个人的其他影响。因为繁殖可以说是任何动物生命中最重要的事件，所以了解社会地位和相关生理因素如何调节繁殖可以指导我们对进化变化的理解。本文回顾了一个社会制度模型的证据，在这个模型中，社会地位严格控制着生育。令人惊讶的是，社会地位的变化在很短的时间内产生了迅速而深远的影响，并从根本上改变了明显的行为，以及调节生殖能力的生理，细胞和分子因素。
Social animals live in complex physical and social environments requiring them to attend and rapidly respond to social and environmental information by changing their behavior. A key social influence is rank or status, a ubiquitous element in animal societies. Rank typically regulates access to reproduction and other resources, among other consequences for individuals. Because reproduction is arguably the most important event in any animals' life, understanding how reproduction is regulated by social status and related physiological factors can instruct our understanding of evolutionary change. This article reviews evidence from a model social system in which reproduction is tightly controlled by social status. Surprisingly, changes in social status have rapid and profound effects over very short time scales and radically alter overt behavior, as well as physiological, cellular, and molecular factors that regulate reproductive capacity.
