在有性繁殖的生物体中，配偶的选择可以强烈地影响适应性。配偶选择的一种形式是配偶复制，在这种情况下，个体通过复制其他个体的配偶选择来利用有关潜在配偶的信息。虽然许多研究都记录了配偶复制行为，但人们对环境条件对这种行为的影响知之甚少。在这里，我们报告了第一个证据，即黑腹果蝇雌性可以在目睹单一配偶选择事件（即速度学习）后获得对一种雄性特征的性偏好。我们还发现，交配复制与气压和气压变化有关，因此，当气压高且不断增加时，即在良好和改善的天气条件下，雌性复制的数量要多得多。这些结果揭示了一种快速的社会观察学习，并强调了气象条件对配偶复制的潜在重要性，这是一种可能导致生殖隔离的特征。(C) 2016年作者。由爱思唯尔有限公司代表动物行为研究协会出版。
Mate choice can strongly affect fitness in sexually reproducing organisms. A form of mate choice is mate copying, in which individuals use information about potential mates by copying the mate choice of other individuals. While many studies have documented mate copying, little is known about the effect of environmental conditions on this behaviour. Here, we report the first evidence that Drosophila melanogaster females can acquire a sexual preference for one male characteristic after witnessing a single mate choice event (i.e. speed learning). We also found that mate copying was correlated with air pressure and air pressure changes, so that females copied far more when air pressure was high and increasing, i.e. in good and improving weather conditions. These results reveal a quick social observational learning and highlight the potential importance of meteorological conditions for mate copying, a trait potentially driving reproductive isolation.
