在Peromyscus小鼠中，建立三维巢的能力是保守的。不同的类群筑巢的潜伏期不同，这表明它们的动机不同。筑巢的潜伏期与气候、挖洞行为或体重无关。一夫一妻制的老鼠比滥交的老鼠有更短的筑巢潜伏期。动物建造的结构，如巢穴，通常可以被认为是促进动物行为研究的扩展表型。对啮齿类动物来说，筑巢既是行为体温调节的重要形式，也是亲代照顾的重要组成部分。因此，巢结构的变化或筑巢行为的优先次序可能对生存和繁殖产生影响，生物和非生物环境因素都可能影响这种差异的适应价值。在这里，我们首先开发了一种新的分析方法来研究鹿鼠（Peromyscus属）筑巢行为的种间变异。通过这一实验，我们发现，虽然Peromyscus小鼠筑巢的复杂性存在一些差异，但开始筑巢的潜伏期差异更为显著。在这里研究的7个分类群中，有4个在得到筑巢材料后的一个小时内筑巢，但这种筑巢的延迟与巢结构的最终差异无关，这表明筑巢的能力在属内相对保守，但物种在筑巢行为的优先顺序上有所不同。我们还发现，筑巢的潜伏期与体型、气候或洞穴的建造无关，这些洞穴会产生小气候。然而，四个筑巢潜伏期较短的分类群都有一夫一妻制的交配系统，这表明筑巢潜伏期的差异可能与社会环境有关。该属内筑巢行为的详细特征为未来研究有助于行为进化的遗传和神经生物学机制提供了重要基础。
HighlightsAbility to build a three-dimensional nest is conserved in Peromyscus mice.Taxa vary in their latency to nest, which suggests differences in motivation.Latency to nest is not linked to climate, burrowing behaviour or body weight.Monogamous mouse species have shorter nesting latencies than promiscuous mice.Structures built by animals, such as nests, often can be considered extended phenotypes that facilitate the study of animal behaviour. For rodents, nest building is both an important form of behavioural thermoregulation and a critical component of parental care. Changes in nest structure or the prioritization of nesting behaviour are therefore likely to have consequences for survival and reproduction, and both biotic and abiotic environmental factors are likely to influence the adaptive value of such differences. Here we first develop a novel assay to investigate interspecific variation in the nesting behaviour of deer mice (genus Peromyscus). Using this assay, we find that, while there is some variation in the complexity of the nests built by Peromyscus mice, differences in the latency to begin nest construction are more striking. Four of the seven taxa examined here build nests within an hour of being given nesting material, but this latency to nest is not related to ultimate differences in nest structure, suggesting that the ability to nest is relatively conserved within the genus, but species differ in their prioritization of nesting behaviour. We also find that latency to nest is not correlated with body size, climate or the construction of burrows that create microclimates. However, the four taxa with short nesting latencies all have monogamous mating systems, suggesting that differences in nesting latency may be related to social environment. This detailed characterization of nesting behaviour within the genus provides an important foundation for future studies of the genetic and neurobiological mechanisms that contribute to the evolution of behaviour.
