该团队以全球6000多万次探测的声学数据集为主题，代表了583种昼夜活动的鸟类，以综合光污染对鸟类发声的影响。光污染平均使发声活动延长50分钟。在繁殖季节，对光污染反应最强烈的物种是大眼睛、开放巢穴、迁徙习性和范围大的物种。长时间的运动可能产生消极、中性或积极的健身效果；记录这些适应性效应和控制光污染是21世纪自然保护面临的挑战。
据悉，光污染破坏了生物体作为生命时间表的明暗线索。尽管研究——典型的对单个物种的聚焦研究——已经记录了光污染景观中鸟类早起发声的情况，但缺乏跨物种、空间和季节的光污染影响的综合研究。

Abstract: Light pollution disrupts light–dark cues that organisms use as timetables for life. Although studies—typically focusing on individual species—have documented earlier morning onset of bird vocalization in light-polluted landscapes, a synthesis of light pollution effects across species, space, and season is lacking. We used a global acoustic dataset of more than 60 million detections, representing 583 diurnal bird species, to synthesize effects of light pollution on avian vocalization. On average, light pollution prolonged vocal activity by 50 min. Light pollution responses were strongest for species with large eyes, open nests, migratory habits, and large ranges and during the breeding season. Prolonged activity may confer negative, neutral, or positive fitness effects; documenting these fitness effects and curbing light pollution are challenges for 21st-century conservation.
