发光二极管（LED）路灯市场正在全球范围内扩大，了解LED灯如何影响野生动物种群非常重要。我们比较了逃避飞行反应的飞蛾蝙蝠回声定位呼叫实验LED照明和无光条件下。值得注意的是，更少的飞蛾执行'powerdive'飞行演习，以回应蝙蝠的呼叫（喂养嗡嗡声序列从夜鹰属）。在LED路灯下比在黑暗中更容易。LED路灯减少了飞蛾的反捕食行为，改变了平衡，有利于它们的捕食者，空中的鹰蝠。
The light-emitting diode (LED) street light market is expanding globally, and it is important to understand how LED lights affect wildlife populations. We compared evasive flight responses of moths to bat echolocation calls experimentally under LED-lit and -unlit conditions. Significantly, fewer moths performed ‘powerdive’ flight manoeuvres in response to bat calls (feeding buzz sequences from Nyctalus spp.) under an LED street light than in the dark. LED street lights reduce the anti-predator behaviour of moths, shifting the balance in favour of their predators, aerial hawking bats.
