使用动态求爱展示来吸引雌性的雄性可能会根据自己的社会环境对其求爱进行战术调整。然而，我们对性信号在复杂的自然环境中是如何调节的知之甚少，在复杂的自然环境中，个人在来自附近和远处对手的信号的背景下竞争注意力。我们使用野生蟋蟀项目的数据对此进行了调查，野生蟋蟀是一种野生蟋蟀种群，通过闭路电视摄像机持续监测。我们在51天的时间里使用了129名男性的100多万个扫描样本来探索唱歌和与其他男性的接近如何影响男性的唱歌行为。我们首先量化了雄性鸣叫重叠的空间网络，以了解它们之间的距离如何影响鸣叫重叠的程度，并发现无论距离如何，整个种群都存在适度的重叠。然后我们使用了控制环境变量影响的更细粒度的分析。在超过1米的距离上，我们发现其他男性的歌唱对焦点男性的歌唱行为有刺激作用，导致男性在相同的时间间隔内歌唱。随着雄性之间距离的增加，歌唱中的重叠部分变得更弱。相反，我们发现，当另一只雄性在非常近的地方(1米以内)唱歌时，雄性更不可能打电话，这表明这是一种抑制效应。这些发现揭示了，在野生种群的动态社交网络中，雄性如何对自己的信号行为进行精细的调整，以回应来自附近和远处的其他雄性的信号。
Males that employ dynamic courtship displays to attract females may tactically adjust their courtship in response to their social environment. However, we know little about how sexual signals are adjusted in complex natural settings, where individuals are competing for attention against a backdrop of signals from nearby and distant rivals. We investigated this using data from the WildCrickets project, a wild population of field crickets,Gryllus campestris, continuously monitored via CCTV cameras. We used over a million scan samples from 129 males across 51 days to explore how the singing and proximity of other males influenced male singing behaviour. We first quantified the spatial network of the males to understand how the extent of singing overlap is affected by the distance between them, and found a moderate overlap across the whole population, regardless of distance. We then used a finer-grained analysis controlling for the effect of environmental variables. At distances greater than 1 m, we found a stimulatory effect of singing by other males on a focal male's singing behaviour, leading to males singing in the same time intervals. The overlap in singing became weaker as the distance between males increased. Conversely, we found that males were less likely to call when another male was singing very close by (within 1 m), suggesting an inhibitory effect. These findings reveal how, in a dynamic social network in a wild population, males perform fine-scale adjustments to their signalling behaviour in response to signalling by other males both nearby and far away.
