人们普遍认为，当男性单独负责筑巢，巢的特点应该反映其所有者的质量和巢本身应该是一个重要的线索，在女性的选择。然而，这并不总是必须的情况下，例如，巢属性是一个不可靠的反映男性的质量。在这里，我们调查女性是否应该喜欢巢的特点，在一个小的海洋鱼类，沙虾虎鱼，Pomatoschistus minutus。先前的研究结果表明，雌性沙虾虎鱼更喜欢拥有建造良好的巢穴（基于顶部堆积的沙子数量）的雄性。然而，目前还不清楚雌性选择雄性是基于巢穴本身的质量，还是其他一些相关的建造者的质量。在目前的研究中，我们发现了相互矛盾的证据，证明状况良好的雄性是否能够将更大比例的卵带到孵化阶段。在野外调查中，我们还发现，身体状况和筑巢程度之间的关系是暂时不稳定的。此外，当我们通过实验将巢的质量与其他雄性性状分离时，我们发现雌性并不喜欢与拥有最精致巢的雄性一起产卵。总之，这些结果表明，女性不一定更喜欢男性的巢特征的基础上，而可能依赖于多种线索时，选择伴侣，其相对重要性应根据上下文而定。版权所有2009年，牛津大学出版社。
It is widely assumed that when males alone are responsible for nest building, nest characteristics should reflect the quality of its owner and that the nest itself should be an important cue in female choice. This, however, does not always have to be the case if, for example, nest attributes are an unreliable reflection of male quality. Here, we investigate whether females should prefer nest characteristics in a small marine fish, the sand goby, Pomatoschistus minutus. Previous findings suggest that female sand gobies prefer males that possess well-built nests (based on the amount of sand piled on top). It was unclear, however, whether females chose males based on the quality of the nest per se or some other, correlated quality of the builder. In the current study, we found conflicting evidence of whether males in good condition are able to bring a greater percentage of eggs to the hatching stage. In a field investigation, we also found that the relationship between body condition and the degree of nest construction was temporally unstable. Furthermore, when we experimentally disentangled nest quality from other male traits, we showed that females did not prefer to spawn with males that had the most elaborate nests. Together, these results suggest that females do not necessarily prefer males based on nest characteristics and may, instead, rely on multiple cues when choosing mates, the relative importance of which should vary depending on context.
