令人惊讶的是，人们对哺乳动物雌性择偶中声音线索的作用知之甚少。在这里，我们研究的反应，女性红鹿（马鹿）男性的咆哮声中，身体大小的声学线索，共振峰，已被重新缩放模拟不同大小的呼叫者。我们的研究结果表明，发情期的红鹿hinds喜欢咆哮模拟较大的呼叫者，并构成了第一个证据表明，雌性哺乳动物使用的声音线索，身体大小在择偶的情况下。我们继续认为，通过女性交配偏好的性选择可能提供了一个额外的选择压力沿着与广播大小相关的信息，在红鹿和其他哺乳动物的雄性-雄性竞争。
Surprisingly little is known about the role of acoustic cues in mammal female mate choice. Here, we examine the response of female red deer (Cervus elaphus) to male roars in which an acoustic cue to body size, the formants, has been re-scaled to simulate different size callers. Our results show that oestrous red deer hinds prefer roars simulating larger callers and constitute the first evidence that female mammals use an acoustic cue to body size in a mate choice context. We go on to suggest that sexual selection through female mating preferences may have provided an additional selection pressure along with male-male competition for broadcasting size-related information in red deer and other mammals.
