Artificial light driver nighttime landscape

项目摘要

Artificial light, from streetlights and other sources, is eroding natural light cycles over large areas of the globe; more than 80% of people now live under light polluted skies. Artificial light is thus giving rise to an environmental pressure on organisms that they have not previously encountered in their evolutionary histories. Documented impacts include effects on the physiology and behaviour of individual organisms, the abundance and distribution of species, and the structure and functioning of ecological communities. However, the exposure of organisms to artificial light in real landscapes, and thus the spatial extent and temporal dynamics of these effects, remain poorly understood. In major part this is because there is a substantial mismatch between the relatively coarse spatial and temporal scales at which artificial light has to date typically been mapped (often using satellites) and the relatively fine spatial and temporal scales at which organisms will often experience artificial nighttime lighting. This lack of detail constrains understanding of how animals move within, and respond to, dynamic lightscapes. In this project we will address this important limitation. We will measure the spatial and temporal distributions of artificial nighttime lighting across urban and suburban sites, and use these data to build generalisable models of their light dynamics. We will then produce high resolution maps that more accurately represent the ecological barriers, fragmentation and patch structure of light in urban and suburban areas and test these with new ecological data on the movements of hedgehogs, bats and moths. Only once ecological risks of artificial light at night have been understood at relevant spatial and temporal scales can better mitigation strategies be implemented to alleviate pressure from this pernicious driver of global change.

来自路灯和其他来源的人造光正在侵蚀全球大片地区的自然光循环；超过80%的人现在生活在光污染的天空中。因此，人造光正在给生物体带来环境压力，这是它们在进化史上从未遇到过的。有据可查的影响包括对单个生物体的生理和行为、物种的丰度和分布以及生态群落的结构和功能的影响。然而，生物体在真实景观中暴露在人造光下的情况，以及这些影响的空间范围和时间动态，仍然知之甚少。这在很大程度上是因为迄今通常绘制人造光地图的相对粗略的空间和时间尺度(通常使用卫星)与生物体经常经历人造夜间照明的相对精细的空间和时间尺度之间存在严重的不匹配。这种细节的缺乏限制了对动物如何在动态光景中移动并对其做出反应的理解。在本项目中，我们将解决这一重要限制。我们将测量城市和郊区人工夜间照明的空间和时间分布，并使用这些数据来建立其光动力学的通用模型。然后，我们将制作高分辨率地图，更准确地表示城市和郊区的生态屏障、光的碎片和斑块结构，并用刺猬、蝙蝠和蛾子活动的新生态数据来测试这些地图。只有在相关的空间和时间尺度上了解了夜间人造光的生态风险，才能实施更好的缓解战略，以减轻这一有害的全球变化驱动因素带来的压力。
