Mate preferences can vary in the direction of the preference, as well as the strength of the preference, and both direction and strength of preference are known to be plastic in many species. Preferences might have a learned component, and current and past social context may influence an individual's choosiness. In the damselfly species Calopteryx splendens, females increase the strength of their mate preferences with sexual experience. Here we show that sexually naïve females selectively respond to conspecific courtship as soon as physical contact has been established, suggesting a role for tactile cues perceived through interspecific morphological differences in secondary reproductive traits. In addition our data also shows that males and females selectively respond to the intensity of the courtship of the potential, conspecific mate, while ignoring such information in heterospecific potential mates. These results underscore that mate choice is the result of dynamic interactions between the sexes, where both current and past information are integrated.

配偶偏好可能在偏好方向以及偏好强度上有所不同,而且已知在许多物种中,偏好的方向和强度都是可变的。偏好可能有一个学习成分,当前和过去的社会环境可能会影响个体的挑剔程度。在豆娘物种华丽色蟌中,雌性会随着性经验的增加而增强其配偶偏好的强度。在这里我们表明,性成熟前的雌性一旦建立身体接触就会对同种求偶行为做出选择性反应,这表明通过次生生殖特征的种间形态差异所感知到的触觉线索发挥了作用。此外,我们的数据还表明,雄性和雌性会对潜在同种配偶求偶行为的强度做出选择性反应,而忽略异种潜在配偶的此类信息。这些结果强调配偶选择是两性之间动态相互作用的结果,其中当前和过去的信息都会被整合。本文是名为《野外认知》的特刊的一部分。
