女性经常表现出对某些男性特征的偏好。然而，人们对雌性在自然栖息地寻找配偶时所使用的行为规则知之甚少。我们研究了领地草莓毒蛙 (Oophaga pumilio) 的交配采样策略和相关成本，该毒蛙拥有类似 lek 的交配系统，其中可能会发生顺序采样和同时采样。我们连续监测两次连续交配期间雌性的采样模式和行为。我们没有发现任何证据表明女性通过拜访男性来比较男性。相反，雌性会与距离最近的雄性交配，无论其声音和身体特征以及领地大小如何。在接受性雌性的自然家庭范围内进行的回放实验表明，接受测试的雌性更喜欢最近的说话者，并且不会区分低和高呼叫率或主导频率。我们的结果表明，O. pumilio 的雌性更喜欢研究群体中距离最近的雄性。我们假设该种群的抽样策略受到以下因素的影响：1）性别比例存在强烈的女性偏见；2）由于强烈的雄性竞争，可用雄性的性状差异较小，从而阻止了低质量的雄性保卫领地和交配。
Females have often been shown to exhibit preferences for certain male traits. However, little is known about behavioural rules females use when searching for mates in their natural habitat. We investigated mate sampling tactics and related costs in the territorial strawberry poison frog (Oophaga pumilio) possessing a lek-like mating system, where both sequential and simultaneous sampling might occur. We continuously monitored the sampling pattern and behaviour of females during the complete period between two successive matings. We found no evidence that females compared males by visiting them. Instead females mated with the closest calling male irrespective of his acoustic and physical traits, and territory size. Playback experiments in the natural home ranges of receptive females revealed that tested females preferred the nearest speaker and did not discriminate between low and high call rates or dominant frequencies. Our results suggest that females of O. pumilio prefer the closest calling male in the studied population. We hypothesize that the sampling tactic in this population is affected by 1) a strongly female biased sex ratio and 2) a low variance in traits of available males due to strong male-male competition, preventing low quality males from defending a territory and mating.
