Cover Story (view full-size image): Plant phenology is closely related to natural cycles of light, which, notably, have been disrupted by artificial light at night (ALAN) due to recent urbanization. Here, we showed that ALAN tended to advance the start date of the growing season (SOS), although the overall response of SOS to ALAN was relatively weak. The phenological impact of ALAN showed a spatially divergent pattern, whereby ALAN predominantly advanced SOS at climatically moderate regions, while at very cold and hot regions, its effect was insignificant or even reversed. Such a divergent pattern was mainly attributed to its high sensitivity to chilling insufficiency, though other mechanisms may also play a part, such as the interplay between chilling, forcing and photoperiods, as well as the difference in the life strategies of species.
