In animals, the expression of diverse reproductive behaviors is hormonally regulated. In particular, vocalizing during courtship has been related to circulating androgen levels, and reciprocally, conspecific vocalizations are known to modulate androgen secretion in vertebrates. The effect of natural sounds of abiotic origin on hormonal status has virtually not received attention. Therefore, we evaluated the vocal responses of male Batrachyla taeniata frogs to conspecific chorus and rainfall sounds in natural and controlled laboratory settings, measuring the testosterone levels of exposed individuals. In field and laboratory conditions, testosterone levels of frogs exposed to 31.5 min of chorus and rain sounds and non-exposed individuals were similar. In the field, frogs increased their call rate in response to playbacks of chorus and rain sound, but the evoked calling activity was unrelated to plasma testosterone. In contrast to the field, frogs showed limited responsiveness to 31.5-min acoustic exposures in the laboratory. Similarly to the field, for vocally active males tested in the laboratory there was no association between call rate and testosterone levels. Additionally, in this group, testosterone levels were higher in vocally active males relative to non-calling individuals. Overall, these results indicate that in B. taeniata testosterone levels are not altered following a short-term exposure to conspecific biotic and to abiotic sounds. Our results are suggestive of a threshold influence of testosterone on the vocal activity of the species studied. Further explorations of the influence of abiotic sounds on endocrine activation are required to understand how animals respond to variable acoustic environmental conditions.

生物音和非生物音会影响野外和圈养中雄蛙(Batrachyla taeniata)的通话活动,但不会影响血浆睾丸激素水平。

在动物中,各种生殖行为的表达受到荷尔蒙调节。特别地,求爱时的发声与循环中的雄激素水平有关,相反,已知同种发声可以调节脊椎动物中雄激素的分泌。非生物来源的自然声音对荷尔蒙状态的影响实际上尚未引起注意。因此,我们在自然和受控的实验室环境中评估了雄性Batrachyla taeniata蛙对特定合唱和降雨声的声音响应,从而测量了暴露个体的睾丸激素水平。在野外和实验室条件下,青蛙在31.5分钟的合唱声和雨声下的睾丸激素水平与未接触个体的睾丸激素水平相似。在野外,青蛙会根据合唱和雨声的播放来提高通话率,但诱发的呼气活动与血浆睾丸激素无关。与野外相反,在实验室中,青蛙对31.5分钟的声音暴露反应有限。与该领域类似,在实验室测试的有声带活动的男性在呼出率和睾丸激素水平之间没有关联。另外,在这一组中,有声活动的男性的睾丸激素水平相对于非呼叫者更高。总体而言,这些结果表明,短期暴露于同种生物和非生物声音后,taeniata B.睾丸激素水平不会改变。我们的结果表明睾丸激素对所研究物种的声音活动有阈值影响。
