城市化可以通过改变感官环境从根本上破坏自然生态系统。预计栖息地干扰将有利于行为灵活、能够适应变化环境的物种。当夜间人造光（ALAN）被引入城市地区时，它有可能通过模糊它们的生物发光求爱信号来阻碍当地萤火虫种群的繁殖。单个萤火虫是否能在明亮的背景下发出更亮的信号以保持可见度仍然是未知数。在这项研究中，我们将雄性水生萤火虫暴露在不同波长和强度的漫射光下，并记录它们的警报闪光信号。当暴露于533 nm或以下的波长时，雄性会发出更亮的信号，但频率会降低。这是萤火虫个体水平光信号可塑性的第一个证据。相反，长波长环境光（≥ 597 nm）不影响信号形态，可能是因为A. FICTA不能感知这些波长。这些结果表明，长波长的照明是不太可能影响萤火虫求偶，它的使用，而不是广谱白色照明可以增加萤火虫保护工作。更一般地说，这项研究证明了生物发光信号可塑性在“嘈杂”的信号环境中的好处，并揭示了城市化的一个重要但未充分研究的后果。
Urbanization can radically disrupt natural ecosystems through alteration of the sensory environment. Habitat disturbances are predicted to favor behaviorally flexible species capable of adapting to altered environments. When artificial light at night (ALAN) is introduced into urban areas, it has the potential to impede reproduction of local firefly populations by obscuring their bioluminescent courtship signals. Whether individual fireflies can brighten their signals to maintain visibility against an illuminated background remains unknown. In this study, we exposed male Aquatica ficta fireflies to diffused light of varying wavelength and intensity, and recorded their alarm flash signals. When exposed to wavelengths at or below 533 nm, males emitted brighter signals with decreased frequency. This is the first evidence of individual-level light signal plasticity in fireflies. In contrast, long wavelength ambient light (≥ 597 nm) did not affect signal morphology, likely because A. ficta cannot perceive these wavelengths. These results suggest long wavelength lighting is less likely to impact firefly courtship, and its use in place of broad spectrum white lighting could augment firefly conservation efforts. More generally, this study demonstrates benefits of bioluminescent signal plasticity in a “noisy” signaling environment, and sheds light on an important yet understudied consequence of urbanization.
