Anyone interested in the topics


Artificial light at night (ALAN) is a relatively new and rapidly increasing global change driver. Evidence is increasing on adverse effects of ALAN on biodiversity and ecosystem functioning, among which disruption of nocturnal plant-pollinator interactions which can reduce the plant reproductive output. However, little is known on the spatial and temporal extent of its effects. Here we tested for the effect of ALAN on mutualistic and antagonistic species interactions on systems respectively located in areas not directly illuminated by ALAN and including day-active species. Combining field and laboratory experiments we show that ALAN effects on species interactions and ecosystem functioning relying on them propagate in the dark area adjacent to an artificially illuminated areas and even to daytime. But this is not the all story... The rest will be presented at the Seminar ;-)

The Biodiversity Seminar Series (BD-Seminars) are organized by the WSL Biodiversity Center. Every two weeks, we aim to host a seminar speaker that presents research or outreach on topics relevant to the biodiversity community at WSL. The seminars are currently exclusively held as online events.
