Abstract

Females of some species improve their reproductive success not only by being choosy and selecting males with certain traits, but also by sequentially mating with multiple males within one reproductive season. However, it is relatively unknown whether females also evaluate parental care during mate choice and, if they do, whether males actively communicate their care status to approaching females. We monitored a natural population of the glassfrog Hyalinobatrachium valerioi, a species with sequential polyandry and paternal care, to assess the role of parental care and advertisement calling on male mating success. Using field observations and acoustic analysis, we found that even in this species which has single-note calls, variations in call parameters allow for individual discrimination. Calling was strongly associated with mating success in H. valerioi males. Males with longer calls achieved the highest total mating success over the entire study period, indicating that females might have a preference for longer calls. Moreover, active calling and the presence of clutches were both linked to male mating success on a given night, although we cannot fully exclude that the link between presence of clutches and mating success is due to attractive call features alone. Call parameters differed between males when they were calling on top of their clutches, compared to sitting on the leaf directly, which might provide reliable cues about parental state to approaching females. These findings demonstrate the prominent role of acoustic communication and female choice in a species with male parental care and sequential polyandry.

有父代照料的玻璃蛙的合群出勤率和鸣叫参数与交配成功率有关。
一些物种的雌性不仅会挑三拣四地选择具有某些特征的雄性,还会在一个繁殖季节内连续与多个雄性交配,从而提高繁殖成功率。然而,雌性在选择配偶时是否也会评估父母的照料情况,以及如果评估的话,雄性是否会主动向接近的雌性传达其照料情况,这些都是相对未知的。我们对玻璃蛙(Hyalinobatrachium valerioi)的一个自然种群进行了监测,以评估父母照顾和广告呼叫对雄性交配成功率的影响。通过野外观察和声学分析,我们发现即使在这种只有单音叫声的物种中,叫声参数的变化也能进行个体鉴别。雄性缬蛙的叫声与交配成功率密切相关。在整个研究期间,叫声较长的雄性交配成功率最高,这表明雌性可能偏好较长的叫声。此外,在特定夜晚,雄性的活跃叫声和是否有胎块都与交配成功率有关,尽管我们不能完全排除胎块的存在与交配成功率之间的联系仅仅是由于有吸引力的叫声特征。与直接坐在叶片上相比,雄性在卵巢顶端发出叫声时的叫声参数有所不同,这可能为接近的雌性提供了有关亲本状态的可靠线索。这些研究结果表明,在雄性亲代照料和连续多育的物种中,声音交流和雌性选择起着重要作用。

期刊介绍: Studies on the whole range of behaving organisms, including plants, invertebrates, vertebrates, and humans, are included. Behavioral Ecology construes the field in its broadest sense to include 1) the use of ecological and evolutionary processes to explain the occurrence and adaptive significance of behavior patterns; 2) the use of behavioral processes to predict ecological patterns, and 3) empirical, comparative analyses relating behavior to the environment in which it occurs.
