Results from a new study published in the Journal of Applied Ecology indicate that dim light pollution may have detrimental effects on insect populations and may explain part of the ongoing, large-scale insect declines around the world. During the study, investigators raised the offspring of moths from urban and rural populations from North- and Mid-European countries and treated them with and without dim light at night. The researchers assessed the induction of diapause, a dormant state that is critical for survival through the winter. Light treatment affected diapause overall, but more so in Mid- than in North-European populations. ...
