气味信号用于男性之间的竞争和侵略性的相互作用进行了很好的研究，在性选择的背景下。相比之下，对女性使用的类似信号知之甚少，尽管目前对女性装饰品和武器的进化感兴趣。现有的证据表明，气味信号是重要的，在雌性哺乳动物之间的竞争性相互作用，减少或逆转男性偏见的性二态性的信号，女性竞争激烈。气味标记通常与女性之间争夺资源或生殖机会的冲突有关。因此，雌性的气味标记可能提供了竞争能力的可靠信号，可以被竞争者和潜在的配偶使用。与这一假设相一致，我们报告说，雌性家鼠的攻击行为与其尿液中排泄的主要尿蛋白（MUP）的量相关，这是一组用于气味标记信号传导的多态性蛋白质。在半自然条件下，具有高MUP输出的雌性更有可能产生由具有高繁殖成功的雄性所产生的后代，而不太可能产生由多个不同的雄性所产生的后代，这表明具有强MUP信号的雌性被特别高质量的雄性所垄断。我们的结论是气味信号是值得更详细的调查调解员的女性竞争。
Odour signals used in competitive and aggressive interactions between males are well studied in the context of sexual selection. By contrast, relatively little is known about comparable signals used by females, despite current interest in the evolution of female ornaments and weaponry. Available evidence suggests that odour signals are important in competitive interactions between female mammals, with reductions or reversals of male-biased sexual dimorphism in signalling where female competition is intense. Scent marking is often associated with conflict between females over access to resources or reproductive opportunities. Female scent marks may therefore provide reliable signals of competitive ability that could be used both by competitors and potential mates. Consistent with this hypothesis, we report that aggressive behaviour of female house mice is correlated with the amount of major urinary protein (MUP) excreted in their urine, a polymorphic set of proteins that are used in scent mark signalling. Under semi-natural conditions, females with high MUP output are more likely to produce offspring sired by males that have high reproductive success, and less likely to produce offspring by multiple different sires, suggesting that females with strong MUP signals are monopolized by males of particularly high quality. We conclude that odour signals are worthy of more detailed investigation as mediators of female competition.
