动物个体间一致的行为差异，或动物个性，越来越多地被认为是性选择的一个重要组成部分。尽管越来越多的证据表明，在双亲照顾的物种中，个性介导的生殖成功的影响，在单亲照顾的物种中，个性和性内竞争或配偶选择之间的联系仍然在很大程度上未被探索。在这里，不关心的性别特别应该寻找具有承诺高质量护理的个性特征的伴侣。因此，我们调查的男性个性的影响，在共同的虾虎鱼，一个完善的模式物种的性选择下，独家男性照顾。使用竞争性试验，我们调查了个性如何影响男性垄断两个核心生殖资源，筑巢地点（雄性-雄性竞争）和准备产卵的女性（女性选择）。个性评分喂养的背景下，因此独立的繁殖。我们发现，缓慢喂养的个人更好地成功垄断巢穴，但女性产卵的决定是独立的两个男性竞争对手的觅食个性。相反，女性表现出显着一致的女性产卵偏好稍重的男性和男性更精致的巢。我们的研究结果表明，健身的好处，男性的个性类型只体现通过男性-男性的竞争环境中，筑巢地点是一个有限的资源，而女性的选择有利于大男性精心巢独立的男性personal.Significance statementAnimal个性可以强烈影响繁殖成功的物种与父母的照顾。我们在普通虾虎鱼中研究了这种联系，这是一种雄性筑巢并独自照顾幼鱼直到孵化的鱼。因此，女性应该选择一个男性的个性特征承诺高质量的照顾。我们对雄性的性格进行了评分，并进行了巢竞争和配偶选择试验。我们发现，男性的个性有巢独占的影响，但没有对女性的交配偏好。相反，雌性在交配决定上非常一致，并且一贯青睐拥有精致巢穴的大型雄性。我们的研究结果表明，男性的个性是重要的巢分配，这是至关重要的环境中，筑巢地点是罕见的。
AbstractConsistent inter-individual behavioral differences in animals, or animal personalities, are increasingly recognized as an important component of sexual selection. Despite growing evidence for personality-mediated effects on reproductive success in species with biparental care, the link between personality and intrasexual competition or mate choice in species with uniparental care remains largely unexplored. Here, the non-caring sex in particular should seek partners with personality traits that promise high quality care. Therefore, we investigated effects of male personality in the common goby, a well-established model species for sexual selection under exclusive male care. Using competitive trials, we investigated how personality affects male ability to monopolize either of two central reproductive resources, nesting sites (male-male competition) and ready-to-spawn females (female choice). Personalities were scored in a feeding context and thus independent of reproduction. We found that slow-feeding individuals better succeeded in monopolizing nests, but that female spawning decisions were independent of the foraging personality of two male competitors. Instead, females showed a remarkably consistent between-female spawning preference for slightly heavier males and males with more elaborate nests. Our findings indicate that fitness benefits of the male personality type only materialize via male-male competition in environments where nesting sites are a limiting resource, whereas female choice favors large males with elaborate nests independent of male personality.Significance statementAnimal personality can strongly affect reproductive success in species with parental care. We studied this link in the common goby, a fish where males build nests and solely take care of the brood until hatching. Hence, females should choose a male whose personality traits promise high quality care. We scored male personalities and conducted nest-competition and mate-choice trials. We found that male personality had an effect on nest monopolization, but not on female mating preferences. Instead, females agreed remarkably well in their mating decisions and consistently favored large males with elaborate nests. Our results show that male personality is important for nest allocation, which is crucial in environments where nesting sites are rare.
