哺乳动物表现出多样化的生殖策略，然而，从进化和生理的角度来看，这种多样性及其复合特征背后的最终和近似机制仍然知之甚少。分布于北美洲和中美洲的Peromyscus属啮齿类动物沿着生活史的梯度呈现多样化，在物种内部和物种之间都有不同的繁殖策略。这种变异为研究生殖多样性提供了一个有用的模型。在此，我们结合文献综述和对六种Peromyscus物种圈养群体繁殖记录的新分析，来评估我们目前对可塑性和局部适应如何促进物候和凋落物投资两类生殖性状多样性的理解。有大量证据表明，物候和凋落物投资的许多特征在种群之间以可能具有局部适应性的方式存在差异，尽管这些特征的可塑性仍然很普遍。然而，这些结论主要是基于两种最广泛分布的Peromyscus物种：P. maniculatus和P. leucopus收集的数据。在繁殖物候学和凋落物性状方面，大部分的大蕈属物种多样性仍未得到充分的研究。最后，我们讨论了使用Peromyscus作为哺乳动物生殖性状多样性和进化模型的关键挑战和考虑因素。本文综述了各种间及各居群间在生殖性状方面的多样性。包括产仔数。我们研究了与环境变化的关系（图右）。我们还使用从实验室收集的Peromyscus菌落（小提琴图，右）收集的大型数据集来测试在普通花园条件下的物种和种群水平差异。种内种群和种内种群在关键生殖性状上存在差异。生态梯度与生殖性状一致。这种性状多样性的生理和遗传基础在很大程度上仍然未知。
Mammals display diverse reproductive strategies, however, the ultimate and proximate mechanisms that underlie this diversity and its composite traits remain poorly understood from both evolutionary and physiological perspectives. The Peromyscus genus of rodents, which is found throughout the north and central Americas, has diversified along life history gradients, varying both within and among species in reproductive strategies. This variation provides a useful model for studying reproductive diversity. Here, we combine a literature review with new analyses of captive colony breeding records from six Peromyscus species to assess our current understanding of how plasticity and local adaptation contribute to diversity in two classes of reproductive traits: phenology and litter investment. There is substantial evidence that many traits underlying phenology and litter investment have diverged among populations in ways that are likely to be locally adaptive, though plasticity in these traits remains common. However, these conclusions are largely based on data collected from the two most widespread Peromyscus species: P. maniculatus and P. leucopus. The majority of Peromyscus species diversity remains understudied regarding reproductive phenology and litter traits. We conclude by discussing key challenges and considerations relevant to using Peromyscus as a mammalian model for reproductive trait diversity and evolution moving forward. In this review, we summarize diversity among Peromyscus species and populations in a number of reproductive traits. including litter size. We examine associations with environmental variation (map, right). We also use a large dataset compiled from lab‐held colonies (violin ploots, right) of Peromyscus to test for species‐ and population‐level differences under common garden conditions. Peromyscus species and populations within species differ in key reproductive traits. Ecological gradients consistently covary with reproductive traits. The physiological and genetic basis of this trait diversity remain largely unknown.
