交配特征和偏好的并发差异对于通过性选择进行生殖隔离的进化是必要的,并且这种共同进化已在不同的谱系中得到证明。然而,择偶偏好在多大程度上足以推动自然界的生殖隔离尚不清楚。特征和偏好不同的谱系之间的自然接触区为测试这种差异的预测进化后果提供了绝佳的机会。草莓毒蛙(Oophaga pumilio)在年轻的博卡斯德尔托罗群岛及其周围表现出极端的颜色多态性。在红色和蓝色异域谱系之间的过渡区域,我们询问女性偏好是否随着肤色而出现分歧,以及在同源区域中是否存在任何不同的偏好。当在红色、蓝色和表型中间的雄性中进行选择时,来自单态红色和单态蓝色种群的雌性都表达了选型偏好。然而,来自接触区的红色、蓝色和中间雌性都更喜欢红色雄性,这表明不同的偏好可能不足以影响行为隔离。我们的结果强调了行为隔离的复杂性,以及需要进行研究来揭示不同偏好对物种形成有贡献和无贡献的情况。
The concurrent divergence of mating traits and preferences is necessary for the evolution of reproductive isolation via sexual selection, and such coevolution has been demonstrated in diverse lineages. However, the extent to which assortative mate preferences are sufficient to drive reproductive isolation in nature is less clear. Natural contact zones between lineages divergent in traits and preferences provide exceptional opportunities for testing the predicted evolutionary consequences of such divergence. The strawberry poison frog (Oophaga pumilio) displays extreme color polymorphism in and around the young Bocas del Toro archipelago. In a transition zone between red and blue allopatric lineages, we asked whether female preferences diverged along with coloration, and whether any divergent preferences persist in a zone of sympatry. When choosing among red, blue and phenotypically intermediate males, females from monomorphic red and monomorphic blue populations both expressed assortative preferences. However, red, blue, and intermediate females from the contact zone all preferred red males, suggesting that divergent preferences may be insufficient to effect behavioral isolation. Our results highlight the complexity of behavioral isolation, and the need for studies that can reveal the circumstances under which divergent preferences do and do not contribute to speciation.
