由动物建造的结构可以传达关于建造者的有用信息，这些信息可以被同种用于质量评估。在鱼类中，巢的建造被认为反映了个体建造者的素质，但人们对个体差异随着时间的推移如何一致知之甚少。如果筑巢确实可靠地反映了建造者的质量，那么我们预计在这种扩展的表型性状中个体之间的变化是一致的。我们测试这一假设在男性三刺，Gasterosteus aculeatus，通过测量巢的重复性特征。我们鼓励从英国威尔士中部的四个种群中捕获的雄性，在标准化的实验室条件下完成三个连续的巢。我们量化了巢的一些结构成分和设计特征，并估计了这些特征的重复性（r）。在种群内，使用的线的数量，巢的面积和沉积在巢顶的基质的质量都是重复的男性（0.39<r<0.51），表明个体男性三刺鱼在他们生产的巢的大小和组成一致。我们的数据支持这一假设，巢的特点可能揭示了重要的信息，个别男性的质量，他们可能，至少在部分，遗传控制。我们讨论这些发现的背景下，在刺鱼和其他物种的巢特征的演变。
Structures built by animals may convey useful information about the builder that may be used by conspecifics in quality assessment. In fish, nest construction has been suggested to reflect qualities of individual builders, but little is known about how consistent individual differences are over time. If nest construction does reliably reflect builder quality, then we expect consistent variation between individuals in this extended phenotypic trait. We test this hypothesis in male three-spined sticklebacks, Gasterosteus aculeatus, by measuring the repeatability of nest characteristics. We encouraged males, caught from four populations in mid-Wales, U.K., to complete three consecutive nests under standardized laboratory conditions. We quantified a number of structural components and design characteristics of nests and estimated repeatability (r) of these traits. Within populations, the number of threads used, the area of the nest and the mass of substrate deposited on top of the nest were all repeatable within males (0.39<r<0.51), showing that individual male three-spined sticklebacks differed consistently in the size and composition of the nests they produced. Our data support the hypothesis that nest characteristics may reveal important information about the quality of individual males, and that they may, at least in part, be under genetic control. We discuss these findings in the context of the evolution of nest characteristics in sticklebacks and other species.
