abstract="This issue of Acta Paediatrica contains a paper by Grech and Borg that explores the seasonality of sex ratios at birth and the effect of the famous volcanic eruption in April 2010, which caused widespread disruption to air traffic all over Europe. The authors report that a slight decline in male births was noted after the eruption and conclude that this provides further evidence that acute and violent incidents, including natural events, can affect the sex ratio. They also state that the sex ratio is a cheap and reliable indicator of the degree of stress experienced by a given population. This article is protected by copyright.
