Hunting for wild meat in the tropics provides subsistence and income for millions 29 of people. Methods have remained relatively unchanged since the introduction of 30 shotguns and battery-powered incandescent flashlights, but due to the short life of batteries in such flashlights, nocturnal hunting has been limited. However, brighter, 32 more efficient light-emitting diode (LED) flashlights, have recently been adopted by 33 hunters. Brighter spotlights increase the freezing response of many species, and 34 greater battery life allows hunters to pursue game for longer and more frequently. 35 Hunters interviewed in African and South American forests, disclosed that LEDs 36 increase the frequency and efficiency of nocturnal hunting, and the number of kills 37 made. These changes were reflected in harvest data in Brazil. The drastic change in 38 efficiency brought about by LEDs, well known to hunters around the world, poses a 39 significant threat to wildlife. We consider the implications for communities, governments, 40 wildlife managers and conservationists

LED 手电筒技术促进了热带地区的野肉提取

在热带地区狩猎野生肉类为数百万人提供了生计和收入 29。自从推出 30 支霰弹枪和电池供电的白炽手电筒以来，方法一直保持相对不变，但由于此类手电筒的电池寿命较短，夜间狩猎受到了限制。然而，最近有 33 个猎人采用了更亮、更高效的 32 个发光二极管 (LED) 手电筒。更亮的聚光灯增加了许多物种的冰冻反应，34 更长的电池寿命让猎人可以更长时间、更频繁地追求游戏。35 位在非洲和南美森林接受采访的猎人透露，LED 36 增加了夜间狩猎的频率和效率，并且杀死了 37 人。这些变化反映在巴西的收获数据中。LED 带来的 38 效率的急剧变化为世界各地的猎人所熟知，对野生动物构成了 39 重大威胁。我们考虑对社区、政府、40 名野生动物管理者和保护主义者的影响
