当表型与环境变化紧密匹配时，表型可塑性可以是适应性的。在蟋蟀中，生物和非生物环境的节律性波动经常导致性活跃个体密度的昼夜节律。鉴于密度强烈影响性选择的强度，我们询问蟋蟀是否在信号行为中表现出可塑性，与社会性环境中的这些节奏波动相一致。我们量化了两种蟋蟀物种，蟋蟀veletis和G。pennsylvania icus。蟋蟀表现出可塑性的交配信号行为，大多数雄性在野外交配活动最高的一天中发出更频繁、更有吸引力的信号。大多数雄性G.在野外交配活动最高的一天中，pennalicus啁啾更频繁，更响亮，脉冲间持续时间、脉冲周期、啁啾持续时间和啁啾间持续时间更短，并且载波频率略高。同样，大多数雄性G.在野外交配活动高峰期，veletis更频繁地啁啾，每个啁啾脉冲更多，脉冲间持续时间、脉冲周期和啁啾持续时间更长，啁啾间持续时间更短，并且载波频率更低。在男性之间的变化，信号可塑性高，一些男性信号在一个明显的适应不良的方式。个体大小解释了G. pennaculicus的可塑性，而G.软腭可塑性总的来说，我们的研究结果表明，蟋蟀表现出表型塑料配偶吸引信号，密切匹配波动的社会性背景下，他们的经验。
Phenotypic plasticity can be adaptive when phenotypes are closely matched to changes in the environment. In crickets, rhythmic fluctuations in the biotic and abiotic environment regularly result in diel rhythms in density of sexually active individuals. Given that density strongly influences the intensity of sexual selection, we asked whether crickets exhibit plasticity in signaling behavior that aligns with these rhythmic fluctuations in the socio-sexual environment. We quantified the acoustic mate signaling behavior of wild-caught males of two cricket species, Gryllus veletis and G. pennsylvanicus. Crickets exhibited phenotypically plastic mate signaling behavior, with most males signaling more often and more attractively during the times of day when mating activity is highest in the wild. Most male G. pennsylvanicus chirped more often and louder, with shorter interpulse durations, pulse periods, chirp durations, and interchirp durations, and at slightly higher carrier frequencies during the time of the day that mating activity is highest in the wild. Similarly, most male G. veletis chirped more often, with more pulses per chirp, longer interpulse durations, pulse periods, and chirp durations, shorter interchirp durations, and at lower carrier frequencies during the time of peak mating activity in the wild. Among-male variation in signaling plasticity was high, with some males signaling in an apparently maladaptive manner. Body size explained some of the among-male variation in G. pennsylvanicus plasticity but not G. veletis plasticity. Overall, our findings suggest that crickets exhibit phenotypically plastic mate attraction signals that closely match the fluctuating socio-sexual context they experience.
