Urbanisation is increasing worldwide at an unprecedented rate and the majority of people now lives in urban areas. This process dramatically alters the spatial environment, fragmenting natural habitat and leading to biodiversity loss. However, a far-less appreciated effect of urbanisation is the modification of the temporal environment. Specifically, the presence of artificial light at night disrupts the natural alternation of light and darkness that organisms use to synchronise their daily, lunar and seasonal rhythms. Such rhythms are one of the most pervasive features of life on Earth, from bacteria to humans, evolved for millions of years in a world where cycles of light and darkness have been extremely predictable. Prominent examples are the activity patterns of animals, diel rhythms of hormones and metabolism, and seasonal reproduction. Studies in humans have linked disruption of circadian rhythms by artificial light at night to negative health consequences, including diabetes, obesity, cardiovascular disease and cancer. However, despite the increasing interest in the ecological effects of artificial light at night, we still lack an understanding of the extent to which it might cause circadian disruption also in wild species living in urban areas, what the outcomes of such disruption will be, and what we can do about it. As with other anthropogenic stressors, it is likely that species differ greatly in their responses. Hence, in this project we will firstly use state-of-the-art biotelemetry to assess how urban life affects circadian rhythms in a carefully selected range of wild bird species that differ in sensitivity to light. We will then experimentally test the effects of artificial light at night on targeted physiological pathways related to health in birds. Last, we will examine the potential for mitigating the effects of light pollution through partial night lighting, a strategy that is largely neglected in the context of circadian disruption, but that could provide both ecological and economic benefits. By integrating these approaches, our project will enable the most comprehensive understanding of both the scale and the mechanisms of the problem of light pollution to date, and explore the basis for a novel mitigation strategy.

城市化正在以前所未有的速度在世界范围内发展，现在大多数人生活在城市地区。这一过程极大地改变了空间环境，破坏了自然栖息地，导致生物多样性丧失。然而，城市化的一个鲜为人知的影响是时间环境的改变。具体来说，夜间人造光的存在扰乱了生物用来同步其日常、月球和季节节律的自然明暗交替。这种节律是地球上生命最普遍的特征之一，从细菌到人类，在一个光与暗的循环非常可预测的世界里进化了数百万年。突出的例子是动物的活动模式，激素和新陈代谢的昼夜节律，以及季节性繁殖。对人类的研究表明，夜间人造光扰乱昼夜节律与糖尿病、肥胖、心血管疾病和癌症等负面健康后果有关。然而，尽管人们对夜间人造光的生态影响越来越感兴趣，但我们仍然不了解它可能在多大程度上导致生活在城市地区的野生物种的昼夜节律中断，这种中断的结果将是什么，以及我们能做些什么。与其他人为压力源一样，不同物种的反应可能存在很大差异。因此，在这个项目中，我们将首先使用最先进的生物遥测技术来评估城市生活如何影响对光线敏感度不同的野生鸟类的昼夜节律。然后，我们将通过实验测试夜间人造光对鸟类健康相关的目标生理途径的影响。最后，我们将研究通过部分夜间照明减轻光污染影响的潜力，这一策略在昼夜节律中断的背景下基本上被忽视，但它可以提供生态和经济效益。通过整合这些方法，我们的项目将能够最全面地了解迄今为止光污染问题的规模和机制，并探索新的缓解策略的基础。
