Red light has no effect on bat activity
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). -
Nocturnal light makes birds change their behaviour
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... -

They can kill aquatic animals, and play havoc with their food web and reproductive cycle. An international team of researchers led by the NIOO makes an urgent case for better wastewater treatment and biodegradable pharmaceuticals.
