27/11/2020 Dutch researchers joining forces in the BioClock consortium - including NIOO's Kamiel Spoelstra - have won 9.7 million euros to keep our biological clocks healthy.
Songbirds change their behaviour and timing when nestboxes are exposed to artificial light at night. "They become light sleepers, literally and metaphorically", says Maaike de Jong (NIOO-KNAW). She successfully defended her thesis on the effects of different colours of light at Wageningen University on Friday. The most surprising effect she's found? Some birds are forced to become more monogamous...
Artificial light at night can have a disruptive effect on bats, but not if the light is red. Switching to red light may therefore limit or prevent habitat loss for rare, light-shy bat species. The latest issue of Proceedings of the Royal Society B publishes results from five years of pioneering research led by the Netherlands Institute of Ecology (NIOO-KNAW).
Kamiel Spoelstra is this year's winner of the Stairway to Impact Award. The Dutch Research Council (NWO) has awarded him the prize for his contribution towards the acquisition and propagation of knowledge about the impact of artificial light on flora and fauna.
We produce more and more light at night. Virtually everybody in Europe or the US lives in a light polluted place: all areas where artificial light always exceeds the light of the moon and the stars. These areas expand with about two percent per year, while already light polluted areas become even brighter at night.
Sperm are critical to successful fertilisation in sexually reproducing animals. The function of sperm – to find and fertilise ova – is universal throughout the animal kingdom, yet the sperm cell is the most morphologically diverse cell type known.
Illumination of forest edges leads to a decrease in moth numbers and changes in the behaviour and success of bigger day as well as night-active animals in the long run. What did we find out at NIOO and what can we do with these results?
